[0002] The cultivation and breeding of industrial hemp has important application value in modern agriculture and medicine. However, the existing industrial hemp cultivation process relies heavily on manual supervision and detection, which not only greatly increases labor costs, but also limits the cultivation efficiency and the ability of large-scale production. In current production practices, researchers and growers usually need to manually monitor the growth status of cannabis plants and make adjustments based on observations. This process is not only time-consuming and labor-intensive, but also involves a certain degree of randomness and luck, making it difficult to achieve precise control and the expected cultivation direction.

DETAILED DESCRIPTION

[0034] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0036] See also Figure 1-Figure 9 , a breeding device for genetic improvement of industrial hemp germplasm according to some embodiments of the present invention is described below.

[0037] The embodiments of the first aspect of the present invention provide a breeding device for genetic improvement of industrial hemp germplasm. In some embodiments of the present invention, Figure 1-Figure 9 As shown, the breeding device comprises:

[0038] The light-transmitting portion 1 is buckled on the foundation 2; a cultivation chamber 101 isolated from the outside is formed between the inside of the light-transmitting portion 1 and the foundation 2, and a cultivation soil layer 3 is laid on the foundation 2 in the cultivation chamber 101; the cultivation soil layer 3 fixes the cannabis plants through preset planting positions; the number and position of the planting positions can be pre-set according to needs, and a cannabis plant is arranged on each planting position.

[0039] The detection unit is installed on the foundation 2, and the cultivation soil layer 3 covers the detection unit; the detection unit is provided with a sampling head that penetrates the cultivation soil layer 3 and extends to the cultivation chamber 101, so as to detect the cannabis plants at predetermined time intervals during their growth.

[0040] The water supply part 4 penetrates the light-transmitting part 1 from the outside and extends to the inside of the cultivation chamber 101; the water supply part 4 includes at least one sprinkler head 401, and the sprinkler head 401 corresponds to a planting position. Each sprinkler head 401 corresponds to a cannabis plant, so as to control the amount of water during cultivation and improvement, and cultivate cannabis plants that meet the use requirements and are more drought-resistant.

[0041] The sampling head and the sprinkler head 401 are connected together to a controller for associated control in cultivation improvement; when the sprinkler head 401 supplies water to the planting position, the sampling head collects the cannabinoid index of the cannabis plant; the controller generates a growth status index of the cannabis plant through the cannabinoid index, and uses the cannabinoid index produced by the cannabis during the growth cycle as an important indicator for improvement, and uses it as a growth status index to facilitate screening and targeted cultivation.

[0042] The present invention provides a breeding device for genetic improvement of industrial hemp germplasm. The light-transmitting part 1 is responsible for providing natural light or controllable artificial light to the inside of the cultivation chamber 101 to ensure that the hemp plants can carry out effective photosynthesis. Transparent or translucent materials are usually used, such as reinforced glass or high-quality plastic film. These materials can not only ensure good light transmittance, but also resist the invasion of external environmental factors; the foundation 2 provides a stable support structure to fix the light-transmitting part 1, and at the same time maintain the structural integrity when the cultivation chamber 101 is isolated from the outside world. The foundation 2 is usually composed of solid building materials, such as concrete or reinforced metal, to ensure the stability and durability of the entire breeding device; the cultivation chamber 101 forms a closed environment to control the air Climate conditions such as temperature, humidity, CO2 concentration, etc. provide an optimal growth environment for cannabis plants. The design of the cultivation room 101 ensures complete isolation from the external environment to prevent the invasion of external pollutants and microorganisms, thereby reducing the risk of diseases and pests; the cultivation soil layer 3 provides the necessary nutrition and support for the cannabis plants. The soil layer is generally composed of soil rich in organic matter, or a cultivation medium specially customized for cannabis plants is used, such as a mixture of coconut bran, perlite and vermiculite; the preset planting positions allow the position and number of plants to be set according to research needs and plant characteristics to maximize space utilization and lighting efficiency. The design of the planting positions allows researchers to adjust the position of the plants according to the needs of the experimental design to support different breeding experiments and observations.

[0043] The light-transmitting portion 1 is automatically adjusted according to the sunlight conditions and the required light cycle, and the light is supplemented by artificial light sources when necessary to simulate the lighting environment required for different growth stages; the cultivation room 101 is equipped with sensors and adjustment equipment, such as temperature and humidity controllers, CO2 generators and air filtration systems to maintain suitable growth conditions and air quality; water and nutrients are supplied regularly through an automated irrigation system to ensure that plants in each planting position can obtain a balanced supply of water and nutrients.

[0044] The detection unit is installed on the foundation 2 and is designed to be located below the cultivation soil layer 3 to ensure that the normal growth of the plants is not affected. The cultivation soil layer 3 covers the detection unit to ensure the representativeness of the sampling and the accuracy of the data, while protecting the detection unit from physical damage; the sampling head passes through the cultivation soil layer 3 from above the detection unit and directly reaches the inside of the cultivation room 101 to directly monitor the environment around the plants. The sampling head is used to collect real-time data on the soil and the surrounding environment, such as soil moisture, temperature, pH value, conductivity, etc.

[0045] The detection unit automatically collects various environmental parameters directly related to plant growth through its sampling head at regular intervals (according to the set time intervals). These data are collected by sensors and transmitted to the data processing center; the collected data are transmitted to a central processor or cloud platform through a wired or wireless network for data recording, analysis and processing. This information can be used to evaluate the growth status of plants and adjust the environmental settings of the cultivation room 101, such as adjusting irrigation, lighting, temperature and humidity; based on the analyzed data, the control system of the breeding device can automatically or manually adjust the conditions in the cultivation room 101 to optimize the plant growth environment and achieve more effective germplasm improvement and breeding efficiency; the detection unit can also be equipped with an early warning system. When it is detected that the plant growth environment or soil conditions deviate from the set optimal range, the system will issue an alarm to prompt the operator to check and intervene.

[0046] The water supply part 4 is configured to penetrate the light-transmitting part 1 from the outside, and the water supply pipeline is introduced from the outside, passes through the light-transmitting part 1 and enters the interior of the cultivation chamber 101. This design can ensure the continuity and safety of the water source and prevent pollution; each planting position corresponds to a sprinkler head 401, and the sprinkler head 401 is directly located above or close to the corresponding cannabis plant to ensure that water is directly and efficiently supplied to the plant; the sprinkler head 401 is designed with an adjustable spraying pattern and flow rate, so that it can provide an appropriate amount of water according to the specific needs and growth stage of the plant, ensuring that each plant can obtain a uniform and consistent water supply to support the balanced and healthy growth of the plant.

[0047] The control system automatically adjusts the activity of the water supply unit 4 according to a preset program or according to the real-time data provided by the detection unit. For example, the irrigation amount and frequency are adjusted according to the feedback data of the soil moisture sensor; the water supply system is equipped with automatic control technology, which can automatically start irrigation at a fixed time or according to demand. This highly automated irrigation system can effectively reduce the waste of water resources and improve the efficiency of water use; by individually controlling each sprinkler head 401, the system can adapt to the specific water needs of each plant, especially in the process of cultivating drought-resistant varieties, which helps to accurately control water; in the breeding process, by selectively adjusting the water supply, the growth response of cannabis plants under different water stress conditions is studied, so as to screen out varieties with strong drought resistance.

[0048] The sampling head and the sprinkler head 401 are both connected to the same controller, so that irrigation and data collection can be carried out in coordination, achieving more efficient data collection and resource management. The controller automatically adjusts the irrigation behavior of the sprinkler head 401 according to the preset program or real-time data, and directs the sampling head to collect the cannabinoid indicators of the plant at critical moments; while the sprinkler head 401 supplies water to the planting position, the sampling head is responsible for collecting cannabinoid indicators from the cannabis plant, such as the content of CBD and THC. These indicators help to evaluate the growth status and efficacy of the plant. The collected data is sent to the controller, which analyzes the data to generate detailed indicators about the growth status of the plant.

[0049] The controller uses algorithms to analyze cannabinoid data collected from the sampling head to evaluate the health and productivity of the plant and its response to specific environmental conditions; based on the cannabinoid index, the controller adjusts the irrigation plan, lighting and other environmental parameters to optimize the growth conditions of the plant and increase the yield of the target cannabinoid; using the cannabinoid index as the basis for screening plants, select those with ideal cannabinoid expression for further cultivation and research, and adjust the cultivation strategy in a targeted manner according to the required cannabinoid expression pattern to cultivate cannabis plants that meet specific usage requirements. By integrating the irrigation system and the plant physiological data acquisition system into one controller, the breeding device can achieve precise control and real-time monitoring of the growth environment of the cannabis plant. This integrated approach not only improves breeding efficiency, but also enhances data accuracy and ease of operation during the cultivation process. Ultimately, this will promote the development of cannabis varieties that grow healthier and have higher medicinal value. In addition, by precisely controlling and optimizing the growth conditions of the cannabis plant, it is possible to maximize resource utilization and minimize environmental impact. When the cannabinoid index decreases, the growth state index also decreases linearly.

[0050] In summary, by integrating the detection unit and the water supply unit 4 with a central controller, real-time monitoring and automatic adjustment of the growth environment and physiological state of the cannabis plant are achieved. This integrated system reduces the need for manual intervention and improves the automation of the breeding process; the design of the water supply unit 4 ensures that each plant can get the appropriate amount of water according to its specific needs, and the precise control of the sprinkler head 401 helps to achieve effective water resource management and improve the drought resistance of the plant. This control mechanism solves the problem of water management; the controller generates plant growth status indicators based on the cannabinoid indicators collected from the sampling head, and these data are used to optimize breeding strategies and cultivation directions. By using the production of cannabinoids as an evaluation and screening criterion, a data-driven method is provided to guide cultivation and breeding decisions, reducing randomness and "luck components".

[0051] Through automation and precise control, the cultivation efficiency and productivity of cannabis plants are significantly improved, and systematic data collection and analysis ensure higher repeatability and predictability; precisely controllable water and environmental control reduce the waste of water resources and energy, while reducing dependence on chemical fertilizers and pesticides, because environmental conditions can be optimized to prevent diseases and pests; by precisely controlling growth conditions and using cannabinoid indicators as breeding standards, plants with specific traits (such as high CBD content or low THC content) can be cultivated, while improving the plant's ability to adapt to adversity, such as drought resistance.

[0052] In any of the above embodiments, the light-transmitting portion 1 includes a light-transmitting outer shell and a pre-embedded positioning member 106 for fixing the light-transmitting outer shell on the foundation 2; the bottom of the pre-embedded positioning member 106 is buried inside the foundation 2, and the top of the pre-embedded positioning member 106 is located above the cultivation soil layer 3 and fixedly assembled with the light-transmitting outer shell.

[0053] In this embodiment, the main function of the light-transmitting shell is to allow natural light or artificial light to penetrate and directly illuminate the cannabis plant to promote the photosynthesis of the plant. The light-transmitting shell is usually made of transparent or translucent materials, such as tempered glass or high-quality plastics, with good light transmittance and weather resistance. The selection of materials needs to take into account the ability to resist ultraviolet rays, impact resistance, and durability under long-term exposure to the external environment; the embedded positioning member 106 is a key component for fixing the light-transmitting shell, and its bottom is buried inside the foundation 2, and the top protrudes from the ground and is located above the cultivation soil layer 3. This design allows the light-transmitting shell to be firmly installed in a predetermined position to prevent displacement or tilting caused by environmental factors (such as wind). The top of the embedded positioning member 106 is fixedly assembled with the light-transmitting shell, usually using bolts, screws or other mechanical fasteners to ensure the stability and safety of the structure.

[0054] The embedded positioning member 106 is embedded deep in the foundation 2, providing solid support for the entire light-transmitting portion 1. This structural design not only ensures the stability of the light-transmitting portion 1 in daily use, but also resists potential damage caused by natural disasters such as strong winds or small earthquakes; through the high light transmittance of the light-transmitting shell, the plants can get enough light, which is essential for the healthy growth of plants. If necessary, the intensity and quality of the light can also be adjusted through the shell (such as by using materials or coatings with different light transmittances) to adapt to specific cultivation needs; the design takes maintenance convenience into consideration. The embedded positioning member 106 makes the installation and removal of the light-transmitting shell simple and quick, and is convenient for daily maintenance and replacement when necessary.

[0055] Specifically, the embedded positioning member 106 includes a steel frame and a cement shell cast on the steel frame and solidified. The embedded positioning member 106 between the cement shell and the steel frame also includes embedded bolts 1061, which are fixedly assembled with the ring bodies on the opposite surfaces of the inner and outer layer solar panels 102.

[0056] As can be seen from the above, the steel frame provides basic structural support for the embedded positioning parts 106, and its solid nature can withstand greater mechanical stress and environmental loads. The steel frame is usually designed to be able to bear weight and resist various external forces, such as wind and earthquake, to ensure the stability of the entire device; the cement shell is cast on the steel frame to form a solid and durable protective layer, further enhancing the stability and durability of the structure. Cement has good weather resistance and corrosion resistance, and can protect the internal steel frame from environmental factors for a long time; embedded bolts 1061 are arranged between the cement shell and the steel frame, and are used to fix the positioning parts to other structural components of the light-transmitting part 1 (such as the inner and outer layer sun panels 102), and the bolts are connected to the ring body on the sun panel 102 to ensure that the light-transmitting part 1 is installed firmly and accurately.

[0057] The combination of the steel frame and the cement shell provides extremely high structural stability and deformation resistance. The steel frame provides the basic skeleton, while the cement shell provides additional weight and protection, so that the entire positioning piece can remain stable even under harsh external conditions; the design of the embedded bolts 1061 allows the relevant components of the light-transmitting part 1 (such as the sun panel 102) to be quickly and safely fixed in place. This fixing method not only improves the installation efficiency, but also ensures the safety and reliability of the structure during use; the overall design of the structure takes into account the needs of wind pressure resistance and earthquake resistance. The combination of the steel frame and the cement shell, as well as the sturdy bolt fixing, work together to resist possible external forces, such as strong winds and seismic activities, and protect the internal plants from being affected.

[0058] Furthermore, the light-transmitting outer shell is composed of a plurality of solar panels 102 which are spliced ​​circumferentially and longitudinally, and adopts an inner and outer double-layer splicing arrangement to form a reserved isolation cavity between the inner and outer layers. The top of the embedded positioning piece 106 is inserted into the inner end of the isolation cavity close to the foundation 2 to form a sealed isolation of the isolation box relative to the external gas environment and the culture chamber.

[0059] As can be seen from the above, the light-transmitting shell is composed of two layers of sun panels 102, which are fixed by precise splicing to form a shell with a composite structure. This double-layer structure not only enhances the physical strength of the shell, but also forms an isolation cavity between the two layers of panels; the isolation cavity plays a role of buffering and isolation, which can effectively isolate external environmental influences, such as temperature fluctuations and external pollution, while maintaining the stability of the environment in the culture room; the top of the embedded positioning member 106 is designed to be inserted into the inner end of the isolation cavity, close to the foundation 2, and such a design ensures a close connection between the entire light-transmitting shell and the foundation 2, and enhances the overall stability of the structure; the setting of the embedded positioning member 106 also helps to form an isolation space that is more sealed relative to the external environment and the interior of the culture room, called an isolation box. This isolation box provides additional protection for the gas environment in the culture room to prevent external pollution and gas exchange.

[0060] Through the double-layer structure of the inner and outer solar panels 102 and the isolation chamber in the middle, the device can effectively control and stabilize the environmental conditions in the culture room. The isolation chamber acts as a heat and gas buffer, reducing the impact of external temperature changes on the environment in the culture room, helping to maintain constant growth conditions; the thermal insulation performance of the double-layer solar panels 102 reduces energy loss, especially in a cultivation environment where temperature control is very important, such as a culture room that needs to maintain a certain temperature. This design allows for better insulation and reduces energy consumption in the heating or cooling system; the sealed isolation box design helps prevent external contaminants, such as dust and pathogens, from entering the culture room, helping to ensure healthy plant growth.

[0061] Specifically, a plurality of filter plates 1021 are installed in the isolation cavity by angle docking, and the light color type required for the preset cultivation direction of the cannabis plant can be pre-set through the filter plates 1021; the filter plates 1021 are also used to connect the inner and outer layers of the sunlight panels 102 of the light-transmitting shell.

[0062] As can be seen from the above, the filter plate 1021 is installed in the isolation chamber by a specific angle docking method. This installation method allows the filter plate 1021 to be firmly fixed between the inner and outer sunlight panels 102, while ensuring that the light can be evenly distributed throughout the cultivation chamber 101. In addition to adjusting the light, the filter plate 1021 also plays the role of a structural connector to enhance the overall stability and sealing of the light-transmitting shell; the required light color type can be pre-set through the filter plate 1021 to meet the needs of cannabis plants for light quality at different growth stages. These filter plates 1021 can selectively filter certain wavelengths of light, such as blue light, red light, etc., according to the physiological needs of plants to promote photosynthesis, flowering control or other specific growth reactions. According to the cultivation goals and growth stages, the filter plate 1021 can adjust the intensity and quality of light, for example, enhance certain wavelengths of light to stimulate better growth reactions or adjust flowering time.

[0063] The filter plate 1021 selectively absorbs or reflects light of a specific wavelength through the characteristics of physical or chemical materials, and only allows light wavelengths that are beneficial to plant growth to pass through. This helps to create the most suitable light environment and improve the efficiency of light energy utilization; by precisely controlling the type and intensity of light, the growth conditions of cannabis plants can be optimized, their growth rate can be enhanced, the growth quality can be improved, and it is possible to control the growth habits of plants, such as the shape of the support, the chlorophyll content, etc.; the combination of the double-layer sunlight panel 102 and the filter plate 1021 in the structure makes the environment in the cultivation room 101 more stable, effectively isolates external environmental interference, such as temperature fluctuations and harmful UV radiation, and ensures that the plants grow in the optimal environment.

[0064] In any of the above embodiments, the light-transmitting portion 1 further comprises a sealing film coil 103, and the sealing film coil 103 is laid on the inner wall of the culture chamber formed by the light-transmitting outer shell to form a primary seal for the culture chamber.

[0065] In this embodiment, the sealing film coil 103 is laid on the inner wall of the light-transmitting shell, close to the shell, and forms the inner wall of the culture chamber. This laying method helps to form a continuous, seamless protective layer. The sealing film is usually made of materials with strong weather resistance, UV resistance and high chemical stability, such as polyethylene (PE), polyvinyl chloride (PVC) or special composite materials, which can resist the invasion of various environmental factors for a long time; the main function of the sealing film is to perform primary sealing on the culture chamber, prevent external air, dust and possible microorganisms and pathogens from invading the interior of the culture chamber, thereby keeping the internal environment clean and stable. In terms of waterproofing and moisture-proofing, the sealing film also plays an important role, especially under humid or highly variable climate conditions.

[0066] By forming a primary sealing layer, the sealing film roll 103 effectively isolates the internal and external environments, which helps control the climate conditions in the culture room, such as temperature, humidity and CO2 concentration, ensuring that these parameters remain within the range most suitable for plant growth; the use of the sealing film roll 103 reduces energy loss, especially the loss of heat energy, thereby reducing the energy consumption of the heating and air-conditioning system. This energy saving not only reduces operating costs, but also helps protect the environment; the design of the sealing film usually takes into account the characteristics of easy installation and easy maintenance. Its replacement and repair are relatively simple, which greatly reduces the cost and workload of daily maintenance.

[0067] Furthermore, between the sealing film coil 103 and the sun panel 102 of the light-transmitting outer shell, the light-transmitting portion 1 also includes an iron beam 104 for supporting the sealing film coil 103 on the sun panel 102, so that an observation cavity is formed between the sealing film coil 103 and the sun panel 102, and the observation cavity is used to form a primary isolation for the culture room, and when a pressure difference is formed between the culture room and the external environment, it is judged whether the air pressure in the culture room meets the expected setting requirements through the expansion or contraction of the observation cavity and the sealing film coil 103.

[0068] As can be seen from the above, the iron beam 104 is installed inside the light-transmitting part 1, specifically between the sun panel 102 and the sealing film coil 103. The iron beam 104 provides the necessary structural support to ensure that the sealing film coil 103 is kept in the proper position and tension to avoid sagging or displacement due to gravity or external forces. The iron material is selected for its firmness and durability, and is suitable for bearing static and dynamic loads for a long time; the observation cavity is located between the sealing film coil 103 and the sun panel 102. This space provides a primary isolation layer for the culture room, which helps to maintain the independence of the internal and external environments, prevent direct gas exchange, and thus maintain the specific climate conditions in the culture room. The observation cavity is also used to monitor the air pressure in the culture room. When the internal and external air pressure difference changes, the sealing film coil 103 will swell or shrink accordingly. By observing this change, it can be determined whether the air pressure in the culture room meets the preset requirements.

[0069] When there is a difference in air pressure inside and outside the culture chamber, the sealing film coil 103 will physically deform (expand or shrink) according to the change in pressure difference. This deformation can be easily observed and measured inside the observation chamber, so that the air pressure state in the culture chamber can be monitored in real time; the observed pressure information can be fed back to the control system, and the relevant equipment (such as ventilation system, gas regulating equipment, etc.) can be automatically adjusted according to the preset environmental parameters to maintain or restore the ideal air pressure and environmental conditions; the structural support of the iron beam 104 and the isolation function of the sealing film are combined to ensure the stability and controllability of the environment in the culture chamber, and at the same time provide an effective environmental monitoring method, making the operation of the entire breeding device safer and more efficient.

[0070] Furthermore, the light-transmitting part 1 further includes a cement enclosure 105 between the cultivation soil layer 3 and the iron beam 104 supported at the end of the sealing film coil 103, and the reeling opening of the sealing film coil 103 is arranged at one end close to the cement enclosure 105, and a laying length of at least one tenth of the overall length is reserved to ensure the sealing integrity of the bottom edge and the top of the culture chamber. In addition, a magnet is arranged on the other side of the sealing film coil 103 away from the iron beam 104, which is used to cooperate with the iron beam 104 to clamp and fix the sealing film coil 103.

[0071] As can be seen from the above, the cement enclosure 105 is installed between the cultivation soil layer 3 and the iron crossbeam 104 to fix and support the sealing film coil 103 to prevent it from shifting or loosening during use. In addition, as a solid physical barrier, the cement enclosure 105 also helps prevent the direct impact of external environmental factors on the interior of the culture room. Cement is used as a enclosure material due to its excellent weather resistance and stability. It can withstand greater physical pressure and environmental loads to ensure durability for long-term use; the reeling port of the sealing film coil 103 is set at one end close to the cement enclosure 105. Such a configuration is conducive to maintaining the consistency of tension when the sealing film is unfolded or rolled up, preventing the film material from loosening. When laying, a laying length of at least one-tenth of the overall length is reserved. This reservation ensures that the sealing film can be sealed and docked with other parts of the culture room at the bottom edge and the top to ensure the sealing integrity of the entire culture room.

[0072] With the support of the cement enclosure 105, the sealing film coil 103 forms a continuous and solid sealing layer, covering the inner wall of the entire culture room from the bottom to the top. This all-round sealing protection helps to isolate external gases, moisture and other potential pollutants, and maintain the stability of the internal environment of the culture room; through the precise configuration of the cement enclosure 105 and the reeling mouth of the sealing film coil 103, the device ensures the stability of the structure and the correct tension of the sealing film. The reserved length allows the sealing film to be properly adjusted when necessary, such as when the temperature changes cause the material to expand or contract, it can still maintain a good sealing effect; the design of the sealing film takes into account the adjustments and maintenance that may be required in actual use. The reserved length allows the sealing film to be replaced or repaired without destroying the existing structure, which improves the convenience and economy of maintenance.

[0073] In any of the above embodiments, the sampling head includes:

[0074] The gas collecting plate 5 is arranged inside the cultivation soil layer 3; the gas collecting plate 5 has a first inner cavity and a plurality of through holes connected to the first inner cavity, which are used for centralized collection of the gas collected by the collecting head.

[0075] A gas collection pipe 6 has one end connected to the through hole; the gas collection pipe 6 extends from the inside of the cultivation soil layer 3 to the cultivation chamber 101; multiple gas collection pipes 6 are arranged along the circumference of the gas collecting plate 5, and the gas collection pipes 6 and the gas collecting plate 5 form a planting position. The planting position formed by the gas collection pipes 6 and the gas collecting plate 5 is not only convenient for calibration in the cultivation chamber 101, but also the amount of soil cultivated for each cannabis plant can be controlled, which is convenient for controlling variables.

[0076] In this embodiment, the gas collecting plate 5 is located inside the cultivation soil layer 3, at the center of the planting position, close to the root of the cannabis plant. The gas collecting plate 5 is provided with a main first inner cavity, which is connected to the external gas collection pipe 6 through multiple through holes. These through holes are used to receive gas from other collection equipment; one end of each gas collection pipe 6 is connected to the through hole of the gas collecting plate 5 to ensure that the gas can flow smoothly from the pipeline into the inner cavity of the gas collecting plate 5. The gas collection pipe 6 is arranged along the circumference of the gas collecting plate 5 to form a structure surrounding the planting position. Such a layout not only helps to mark each planting position, but also can accurately control the environment around each plant.

[0077] Furthermore, a positioning rod 8 is installed along the longitudinal direction of the gas collecting plate 5, and the positioning rod 8 is respectively inserted into the foundation 2 and the cultivation soil layer 3. Sealing rings 801 are respectively installed on the upper and lower surfaces of the positioning rod 8 corresponding to the gas collecting plate 5, and the sealing ring 801 covers the connection between the positioning rod 8 and the gas collecting plate 5.

[0078] As can be seen from the above, the positioning rod 8 is arranged longitudinally along the gas collecting plate 5, with one end inserted into the foundation 2 and the other end extending to the cultivation soil layer 3. This layout enables the positioning rod 8 to provide solid support and precise positioning for the gas collecting plate 5. The setting of the positioning rod 8 ensures the stability of the position of the gas collecting plate 5 in the soil layer, and prevents the position of the gas collecting plate 5 from changing or tilting due to soil movement or other physical interference; the sealing ring 801 is installed on the upper and lower surfaces of the connection between the positioning rod 8 and the gas collecting plate 5 to provide additional sealing protection. These annular seals prevent gas leakage between the gas collecting plate 5 and the cultivation soil layer 3, ensuring the integrity and accuracy of gas collection. The sealing ring 801 is usually made of rubber or other flexible but durable materials to adapt to gases of different environmental conditions and chemical properties.

[0079] The positioning rod 8 ensures the stability of the vertical and horizontal positions of the gas collecting plate 5 in the soil layer by physical insertion. This physical fixing method is the basis for the gas collecting plate 5 to effectively collect gas and ensures the reliability of the equipment in long-term operation; the function of the sealing ring 801 is to ensure that there will be no gas leakage at the interface between the gas collecting plate 5 and the positioning rod 8. This sealing measure helps to maintain the purity of the collected gas and prevent external pollutants from entering the gas collection system. When the gas is introduced into the first inner cavity through the through hole of the gas collecting plate 5, the sealing ring 801 ensures that these gases will not escape during the transmission process, thereby improving the accuracy of data collection and the overall efficiency of the system; the design of the positioning rod 8 and the sealing ring 801 also takes into account easy maintenance and overhaul. When it is necessary to inspect or replace the gas collecting plate 5 and its components, the operator can easily access the positioning rod 8 and the sealing ring 801 to perform necessary maintenance work.

[0080] In any of the above embodiments, the spray head 401 and the other port of the gas collection pipe 6 are blocked by the cannabis plant, and the gas collection pipe 6 obtains the gas around the cannabis plant to collect cannabinoid indicators; when the spray water is sprayed and contacts the cannabis plant, the gas collection pipe 6 is set corresponding to the cannabis plant. When collecting air, the wet and water-containing leaves of the cannabis plant can play a role of primary filtration. On the one hand, it isolates large particles of debris, and on the other hand, it can block to a certain extent the volatile components generated by more cannabis plants due to the airflow. In addition, the wet and water-containing leaves of the cannabis plant can absorb volatile components that are easily soluble in water, which can effectively reduce the impurity components in the collected air and facilitate component detection.

[0081] In this embodiment, one end of the gas collection pipe 6 is connected to the through hole of the gas collecting plate 5, and the other end extends to the vicinity of the cannabis plant, but is kept at a certain distance by the physical barrier of the plant. This arrangement enables the gas collection pipe 6 to capture the gas near the leaves of the plant; the spray head 401 is used to spray water on the cannabis plant, which not only provides the necessary water resources, but also affects the gas collection process through the contact between the water droplets and the plant leaf surface.

[0082] When the sprinkler head 401 sprays water on the cannabis plant, the leaves of the plant become wet. The gas sampling tube 6 is close to the plant and can use the plant leaves as a primary filter layer when inhaling air. The plant leaves can effectively capture and absorb volatile organic compounds that are easily soluble in water when wet, while blocking larger particulate impurities. When spraying water, due to the humid environment of the leaf surface, the plant may release more volatile components. After these components are partially dissolved in the water film on the leaf surface, they are more easily captured by the gas sampling tube 6. In addition, the wet state of the plant leaves also helps to reduce the impurity content in the air, thereby improving the purity of the collected gas samples, which is convenient for subsequent component analysis and detection. The collected gas samples are transmitted to the analysis equipment through the gas sampling tube 6 to detect chemical components such as the cannabinoid content. This precise data support can be used to evaluate the growth status, environmental adaptability and physiological response of the plant. The design of the system also helps to standardize experimental conditions and data collection, making the research results more reliable and repeatable.

[0083] Furthermore, the water supply unit 4 also includes a water supply pipe group 402, which is located in the culture chamber and has multiple water supply ports. Each water supply port is connected to the spray head 401 through a high-pressure hose 403 to spray water on the interior of the culture chamber. The water supply pipe group 402 is connected to the external water supply network through a control valve.

[0084] As can be seen from the above, the water supply pipe group 402 is installed inside the culture room, usually arranged along the top or side wall of the culture room to achieve uniform coverage of the entire culture space. The water supply pipe group 402 is provided with multiple water supply ports, each of which is connected to the sprinkler head 401 through a high-pressure hose 403. This design allows water to be sprayed directly and evenly onto each plant; the water supply port and the sprinkler head 401 are connected to ensure the continuity and stability of the water flow under water pressure. The high-pressure hose 403 is made of pressure-resistant material to withstand the operating pressure of the water supply system, and is designed to provide an adjustable spraying pattern of fine to coarse water droplets to adapt to different irrigation needs and plant growth stages.

[0085] The water supply pipe group 402 is connected to the external water supply network through a control valve. The function of the control valve is to adjust the water flow and pressure entering the water supply pipe group 402, thereby controlling the amount of water sprayed on the plants. The control valve is usually programmable or manually adjusted, so that the irrigation system can operate according to a preset irrigation plan or real-time plant needs; the design of the water supply pipe group 402 ensures uniform irrigation of the plants in the entire culture room. The distribution and spraying pattern of the sprinkler head 401 are optimized to cover the maximum plant area, and the droplet size is adjusted according to the size and growth stage of the plant. The high-pressure hose 403 ensures that sufficient water pressure can be maintained even at a long distance or high position to ensure that water reaches each plant evenly.

[0086] In any of the above embodiments, the cannabinoid index includes the CBD content of the cannabis plant, the CBD content is cannabidiol, and the CBD content is characterized by the VOCs concentration of the gas. VOCs can be selected from one or more of the following categories: pinene, limonene, caryophyllene and myrcene; by controlling the amount of sandblasting water of the sprinkler head 401, the water effect on the cannabis plant can be controlled to produce water stress. Cannabidiol and the VOCs released by cannabis are both products of secondary metabolism. Through water stress, the CBD yield of the cannabis plant can be effectively increased and THC (tetrahydrocannabinol) can be reduced in the primary stage. In order to ensure the medical effect of industrial hemp, more CBD with medical efficacy but no psychoactive effect is needed to reduce THC with psychoactive effect and entertainment purpose; in deeper water stress, the cannabis plant will reduce the generation of secondary metabolism in order to ensure inventory, so it is necessary to control the degree of water stress, which can both generate the ability of CBD and increase the drought resistance of the cannabis plant.

[0087] In this embodiment, the sprinkler head 401 achieves water stress on the cannabis plant by controlling the amount of water. The sprinkler system can adjust the amount and frequency of water to accurately control the degree of water stress suffered by the plant. By changing the amount of water sprayed, different degrees of water stress can be applied at different stages of plant growth to stimulate or inhibit specific physiological responses; water stress has been shown to affect the secondary metabolism of plants, including the synthesis of CBD and THC. Moderate water stress can promote the synthesis of CBD, because plants may increase the production of certain stress-resistant secondary metabolites to cope with stress. Specific volatile organic compounds, such as pinene, limonene, cinnamaldehyde and menthene, are also products of secondary metabolism, and their production can be affected by water stress. Changes in the concentration of these compounds can be used as an indicator to evaluate the response of plants to water stress.

[0088] Moderately increasing water stress in the early stages of plant growth can stimulate the synthesis of CBD and may reduce the synthesis of THC, because plants may prioritize the synthesis of secondary metabolites that contribute to their survival, and control the amount and frequency of water in the sprinkler system to achieve the desired stress level. Precise control of the sprinkler system allows experimenters to adjust water supply based on plant growth response and desired compound production; continuously monitor plant growth and changes in chemical composition, such as CBD and THC content, and the release of VOCs. These data can be collected in real time through networked sensors and analytical instruments, and sprinkler strategies can be adjusted based on the collected data to optimize CBD production and control THC content, while ensuring that plants do not reduce growth vitality or overall levels of secondary metabolism due to excessive stress.

[0089] In any of the above embodiments, the detection unit further includes:

[0090] The bottom rail 7 is arranged on the foundation 2 and is connected to the gas collecting plate 5. A second inner cavity 701 is formed inside the bottom rail 7, and the second inner cavity 701 is connected to the first inner cavity through a through hole.

[0091] The detector is connected to the second inner cavity 701; the detector obtains the cannabinoid index through the gas, and the detector can be placed independently outside the culture chamber or inside the culture chamber; when the detector is placed outside the culture chamber, the detector is also connected to the external air environment to discharge the detected waste gas and maintain the same air pressure as the external gas environment.

[0092] In this embodiment, the bottom rail 7 is arranged on the foundation 2 as a direct support structure of the gas collecting tray 5 to ensure the stability and correct position of the gas collecting tray 5 in the soil layer. The design of the bottom rail 7 includes sufficient strength and rigidity to bear the weight and pressure of the gas collecting tray 5 and the gas transmitted therethrough; a second inner cavity 701 is formed inside the bottom rail 7, and this inner cavity is connected with the first inner cavity on the gas collecting tray 5 through a through hole. This connection design allows the gas collected from the gas collecting tray 5 to flow smoothly into the second inner cavity 701 of the bottom rail 7, and finally be transmitted to an external analysis or processing device. The design of the second inner cavity 701 ensures the continuity and efficiency of the gas flow and prevents any potential blockage or leakage.

[0093] The detector can be placed independently outside or inside the culture chamber. The location is determined according to actual needs and operational convenience for easy monitoring and maintenance. The detector is connected to the second inner cavity 701 and receives gas samples transmitted from the gas collecting plate 5 through the bottom rail 7; the detector analyzes the acquired gas through various sensors and analysis techniques (such as gas chromatography, mass spectrometry, etc.), specifically targeting cannabinoid indicators, such as the concentration of components such as CBD and THC, and other related volatile organic compounds (VOCs). The detector is usually equipped with a data processing unit inside, which can process and analyze data in real time, and output the results for the evaluation of plant growth status and the adjustment of environmental control.

[0094] The gas collected from the gas collecting plate 5 is transmitted to the detector through the second inner cavity 701 of the bottom rail 7. This direct connection ensures the integrity of the gas sample and avoids contamination; the detector analyzes the gas sample to identify and measure the content of cannabinoids and other chemicals. These data are helpful in understanding the physiological response of plants, optimizing cultivation conditions and verifying breeding results; when the detector is placed outside the culture chamber, it also needs to be connected to the external air environment so that the detected waste gas can be safely discharged. This not only protects the internal environment, but also helps to maintain the air pressure balance between the detector and the culture chamber, preventing changes in external air pressure from affecting the internal environment and test results.

[0095] Also, the detector can be:

[0096] Gas chromatography-mass spectrometry (GC-MS) combines the techniques of gas chromatography (GC) and mass spectrometry (MS) to separate and identify individual compounds in complex samples; the sample is first heated in the gas chromatograph, causing the compounds to evaporate and separate through the chromatographic column. Different compounds migrate at different speeds in the column, allowing separation. These separated compounds are then introduced into the mass spectrometer and further analyzed and identified based on their mass-to-charge ratio (m / z).

[0097] High Performance Liquid Chromatography (HPLC) is a technique used to separate, identify and quantify the various components in a liquid sample; the sample is passed under high pressure through a chromatographic column filled with a stationary phase. Different compounds move at different rates in the column due to differences in their interactions between the mobile phase (solvent) and the stationary phase, resulting in separation. Detection usually uses a UV / visible detector or other type of detector to identify and quantify the compounds.

[0098] Real-time polymerase chain reaction (qPCR), qPCR technology is often used to quantitatively analyze DNA samples, and can also be used to detect the expression of specific genes, which are related to the biosynthesis of certain specific compounds in cannabis. qPCR monitors the real-time progress of DNA replication by measuring the accumulation of fluorescent markers during the PCR reaction. The increase in fluorescent signal is proportional to the initial amount of target DNA, thus achieving quantitative analysis.

[0099] Mass spectrometry (MS) is a technique used to determine the mass and structure of sample molecules; sample molecules are ionized into charged particles and then separated according to their mass-to-charge ratio in an electromagnetic field. By analyzing the mass spectrum, the mass, structure and quantity of the molecules can be determined.

[0100] Ultraviolet-visible spectroscopy (UV-Vis) is used to determine the concentration of compounds in a sample that absorb ultraviolet or visible light; when light passes through a sample, light of a specific wavelength is absorbed. The amount of light absorbed is proportional to the concentration of a specific compound in the sample, and the concentration of the compound can be calculated using Beer's Law.

[0101] Any of the above embodiments further includes an air supply unit, which is arranged on the light-transmitting portion 1 ; the air supply unit is connected to the cultivation chamber 101 , and an electromagnetic valve 601 is installed on the gas sampling pipe 6 .

[0102] Before the solenoid valve 601 opens the gas collection pipe 6, the air supply unit is used to adjust the air pressure in the cultivation chamber 101 to a preset value higher than the internal air pressure of the gas collection pipe 6. The preset value can be set according to the specific needs of the detection, and the selection range can be selected between 102% and 110% of the standard atmospheric pressure value, so as to automatically press the internal air of the cultivation chamber into the gas collection pipe 6.

[0103] In this embodiment, the air supply unit is arranged above the light-transmitting portion 1 and is connected to the cultivation chamber 101. The air supply unit is responsible for regulating and controlling the air pressure in the cultivation chamber 101. The air supply unit can adjust the air pressure in the cultivation chamber 101 to a preset value higher than the air pressure inside the gas sampling tube 6. This preset value is set according to the detection requirements and is usually between 102% and 110% of the standard atmospheric pressure. The solenoid valve 601 is installed on the gas sampling tube 6 to control the flow direction and flow rate of the gas. It is opened only when gas needs to be collected, thereby controlling the timing and amount of gas sample collection.

[0104] Before the solenoid valve 601 is opened, the air supply unit increases the air pressure in the cultivation chamber 101 to a preset value to create a pressure difference, so that when the solenoid valve 601 is opened, the air in the cultivation chamber 101 can be automatically pressed into the gas sampling tube 6. This pressure difference drives the gas to flow into the gas sampling tube 6 to ensure the continuity and representativeness of the gas sample; the operation of the solenoid valve 601 is performed by the control system according to the set sampling plan. When it is necessary to collect gas samples, the solenoid valve 601 is opened to allow the pressure-adjusted gas to flow into the gas sampling tube 6, and then transmitted to the detection equipment for analysis. The solenoid valve 601 remains closed when it is not necessary to collect, which can prevent external gas from contaminating the sample and avoid unnecessary loss of internal gas; by controlling the pressure difference between the inside and outside of the cultivation chamber 101, the air supply unit and the solenoid valve 601 jointly ensure efficient and accurate collection of gas. This method not only improves the quality of gas samples, but also reduces the complexity of operation and the possibility of human error.

[0105] Furthermore, the air supply unit may be: an air pressure booster pump, a pressure regulating fan, a centrifugal fan, a variable speed drive fan and an HVAC system component.

[0106] In any of the above embodiments, all the solenoid valves 601 located at the same planting position are grouped together, and each group of solenoid valves 601 is electrically connected to the controller, so that the opening and closing of the gas sampling pipe 6 can be controlled by the controller, thereby realizing the collection and detection of the surrounding gas of different numbers of cannabis plants in each detection.

[0107] Each time the sprinkler head 401 supplies water, the controller generates a first instruction to open one or more groups of solenoid valves 601 to achieve collection control based on the cannabis plant.

[0108] In this embodiment, all solenoid valves 601 located in the same planting position are regarded as a group. Such grouping allows multiple gas collection points in the same planting area to be uniformly controlled. Each group of solenoid valves 601 is connected to a central controller through wires. This controller is responsible for sending an open or close signal to the solenoid valve 601 and operating according to the set sampling plan; the controller can be programmed to accurately control the opening and closing of each solenoid valve 601 according to the experimental design or growth monitoring requirements. This includes controlling the time, frequency and duration of opening and closing. The program setting of the controller allows the selection of opening a different number of solenoid valves 601 in each detection, so that the gas around a specific number and position of cannabis plants can be collected as needed.

[0109] When gas collection is required, the controller sends a signal to a specific solenoid valve 601 according to a preset program, instructing it to open. The opened solenoid valve 601 allows gas to flow from its corresponding gas collection pipe 6 and be transmitted to the detection equipment. The controller can activate different solenoid valves 601 simultaneously or sequentially to collect gas samples from different planting positions according to the requirements of the experimental design; by controlling the activities of different solenoid valves 601, gas can be collected from specific plants or plant groups, which helps to study the physiological responses of plants under specific conditions. The collected gas samples are analyzed to evaluate the health status, physiological changes or responses to environmental changes of the plants, such as water stress, light changes, etc.

[0110] The main task of the controller is to receive environmental and plant physiological data, generate instructions based on these data, control the water supply of the sprinkler head 401 and the opening of the corresponding solenoid valve 601, and the controller is programmed to generate a first instruction to open a specific group or multiple groups of solenoid valves 601, and these instructions are synchronized with the water supply time of the sprinkler head 401; it is responsible for providing the necessary water to the cannabis plants, regulating the plant growth environment, such as humidity and soil moisture, etc., all of which may affect the gas composition released by the plants, controlling the opening and closing of the gas collection pipe 6, and opening it during water spraying according to the instructions of the controller to collect the gas environment changed due to irrigation.

[0111] When the sprinkler head 401 starts to supply water, the controller detects the irrigation signal and simultaneously generates instructions to open one or more sets of solenoid valves 601. These instructions ensure that the gas sampling pipe 6 is open when water acts on the plant and may cause the plant to release new or increased volatile organic compounds (VOCs); the solenoid valve 601 is opened according to the instructions of the controller, allowing gas samples to be collected from around specific plants. Such control is not only for a single plant, but can also be extended to multiple plants. Depending on the preset collection strategy and experimental requirements, the opening of each set of solenoid valves 601 is synchronized with a specific spraying cycle, allowing researchers to more accurately analyze the impact of water stress on the physiological state of the plant; the gas samples collected during the opening of the solenoid valve 601 are sent to analytical equipment (such as a gas chromatograph-mass spectrometer) for chemical composition analysis to identify and measure the concentration of key compounds including cannabinoids.

[0112] In any of the above embodiments, a first judgment threshold is set in the controller, and the first judgment threshold is used to judge whether the currently acquired growth status index is qualified. The first judgment threshold is used to judge the growth status index to determine whether the current cannabis plant can withstand the current degree of water stress.

[0113] If the currently acquired growth status indicator is unqualified, the controller generates a second instruction to continuously close the corresponding solenoid valve 601 to indicate that the cannabis plant is judged to be in an eliminated state during breeding; the second instruction has a higher priority than the first instruction, and the cannabis plant will no longer be trimmed and tested in subsequent gas collection.

[0114] In this embodiment, a first judgment threshold is set in the controller, which is a preset numerical value or parameter set for evaluating whether the growth status indicators of the plant meet the requirements of stress resistance and healthy growth. The controller receives real-time data about the growth environment and physiological status of the plant by connecting to multiple sensors (such as soil moisture sensors, gas analyzers, etc.); these indicators may include physiological and chemical parameters of the plant, such as chlorophyll content, cannabinoid content, plant moisture status, etc. The controller analyzes the data received from the sensor and compares it with the first judgment threshold.

[0115] The sensor regularly or continuously monitors key indicators of the plant and its environment, such as moisture, nutrient status, concentration of physiologically active substances, etc., and transmits the data to the controller; after receiving the data, the controller compares the measured value with the first judgment threshold. If the growth status indicator is lower than the threshold, it indicates that the plant may not be able to adapt to the current level of water stress. According to the judgment result, the controller can automatically adjust the irrigation strategy, such as increasing water supply to alleviate water stress, or adjusting other environmental parameters to support the health and growth of the plant; the controller can also record the plant's response data and the adjustment measures taken for future decision optimization and model establishment. In long-term operation, through accumulated data and feedback, the controller can more accurately set thresholds and response strategies to improve the overall health and yield of the plant.

[0116] The controller is provided with an algorithm and a logic judgment standard for evaluating the growth status index of the plant, including a preset first judgment threshold. When the data obtained by the controller from the connected sensor shows that the growth status index of the plant is lower than the first judgment threshold, the controller generates a second instruction to instruct to continuously close the solenoid valve 601 corresponding to the plant; the priority of the second instruction is higher than any other instruction to open the solenoid valve 601 (the first instruction), ensuring that once the plant is judged to be unqualified, its related gas collection is terminated. This control logic ensures that resources are concentrated on plants that are expected to produce high-quality cannabinoids, while reducing investment in plants that do not perform well.

[0117] The controller receives and analyzes data from various sensors in real time. These data reflect various growth status indicators of the plants. Once the indicators of a plant are lower than the set threshold, it indicates that it may not be suitable for continued breeding or research. The controller automatically generates a second instruction based on the evaluation results to continuously close the solenoid valve 601 of the corresponding plant, blocking any further gas collection from the plant. Since the second instruction has a higher priority than the first instruction, even during a regular collection cycle, the solenoid valve 601 of the plant will remain closed and no data will be collected. By eliminating plants with poor performance, the controller helps optimize resource allocation and ensures that water, nutrients and monitoring resources are used for plants that have the potential to achieve or exceed breeding goals. This strategy also helps maintain the overall health and production efficiency of the culture room and improves the success rate of research and commercial breeding.

[0118] In any of the above embodiments, the number of second instructions is a, the number of planting positions is b, and the ratio t=a / b. The controller determines the improvement state of the cultivation room in the current growth cycle of the cannabis plant according to the ratio t. By performing a quantity ratio, the controller can obtain the proportion of cannabis plants in the cultivation room 101 that can continuously resist water stress.

[0119] In this embodiment, the data analysis module built into the controller is responsible for calculating the ratio of the number of plants whose solenoid valves 601 have been closed due to failure to meet the growth status index to the total number of planting positions. This ratio provides a quantitative indicator showing the proportion of plants that can continue to resist the current water stress conditions among the total plants. Through the ratio calculation, the controller evaluates the improvement status of the cultivation chamber 101 in the current growth cycle of the cannabis plants, especially the degree of improvement in resistance to water stress. The controller may adjust the degree of water stress or other environmental parameters based on the calculation results to optimize the growth conditions and increase the proportion of stress-resistant plants.

[0120] The controller continuously monitors the growth status indicators of each planting position, and records in real time the events that require closing the solenoid valve 601. The controller calculates in real time the ratio of the number of plants for which the solenoid valve 601 is closed to the total number of planting positions, and uses this data as a basis for evaluating the improvement status. Based on the calculated ratio, the controller can dynamically adjust the intensity of water stress, such as reducing water stress to reduce the elimination rate, or increasing water stress to further screen out only the strongest plants. Through this dynamic adjustment, the controller can more effectively optimize the plant germplasm of the entire cultivation room 101 and improve the overall resistance of the plants to adverse growth conditions.

[0121] In any of the above embodiments, the controller is also provided with a second judgment threshold that changes with the growth cycle of the cannabis plant. Since the cannabinoids and VOCs generated by the cannabis plant have very large differences in different growth stages, the judgment of the cannabinoid index needs to be made according to different growth stages. The controller adjusts the water supply amount and / or water supply frequency of the sprinkler head 401 through the second judgment threshold and the cannabinoid index to control the degree of water stress.

[0122] In this embodiment, the second judgment threshold set in the controller is dynamically adjusted according to the different growth stages of the cannabis plant to adapt to the natural fluctuations of cannabinoids and VOCs in the growth cycle. The controller can identify the current growth stage of the cannabis plant and adjust the second judgment threshold accordingly. For example, different cannabinoid and VOCs expression levels may be required in the early growth stage, flowering stage or maturity stage; water supply and frequency control: based on the output of the second judgment threshold, the controller adjusts the water supply and / or water supply frequency of the sprinkler head 401 to accurately control the degree of water stress, which directly affects the synthesis of cannabinoids and VOCs. By accurately controlling the water supply, the controller helps the plant achieve optimal biochemical product synthesis efficiency during the critical period.

[0123] The controller monitors the growth status and environmental conditions of the plants in real time by connecting to the sensor network, such as soil moisture, plant size, the start of flowering, etc. The controller uses these data to determine the growth stage of the plant and adjusts the second judgment threshold based on this stage to adapt to the specific needs of cannabinoid and VOCs production at different stages; based on the analysis results of the growth stage and the second judgment threshold, the controller automatically adjusts the operation of the sprinkler head 401 to ensure that the plants receive an appropriate amount of water stress and promote the optimal production of the required chemicals. The controller continuously evaluates the effectiveness of the adjusted irrigation strategy and iteratively optimizes it based on the actual cannabinoid and VOCs measurement results to fine-tune future irrigation plans.

[0124] In any of the above embodiments, the controller can be independently installed on the foundation 2 of the culture chamber, or can be centrally controlled outside a plurality of relatively independent light-transmitting parts 1; and the controller includes:

[0125] The data collection module is responsible for collecting real-time data from sensors, sampling heads, detectors and other equipment, including soil moisture, air pressure, cannabinoid indicators (such as CBD content) and VOCs concentration, etc., to provide basic data input for the system and ensure that subsequent analysis and decision-making have reliable data support.

[0126] The data analysis module processes and analyzes the collected data, evaluates the growth status indicators of the cannabis plants, and compares these indicators with the preset first judgment threshold and second judgment threshold; judges the current health status of the plants and their response to water stress, generates an analysis report, and provides a basis for subsequent decision-making.

[0127] The judgment and decision module is internally provided with a first judgment threshold and a second judgment threshold that can be adjusted according to the cultivation requirements; the first judgment threshold is used to evaluate whether the plant growth status index is qualified. If it is unqualified, the second instruction is triggered; the second judgment threshold is used to adjust the threshold according to the growth cycle changes of the cannabis plant, which is used to optimize the water management strategy; the second instruction is generated: when the plant is unqualified, a second instruction is generated to continuously close the corresponding solenoid valve 601, and the priority is higher than the first instruction, and a decision is made according to the analysis results and the preset judgment criteria to ensure the intelligent regulation of the system. Among them, the first judgment threshold and the second judgment threshold are both values ​​that can be set according to the actual cultivation and screening requirements.

[0128] The execution control module receives the instructions from the judgment and decision-making module and performs corresponding operations, including controlling the water supply and frequency of the sprinkler head 401, controlling the opening and closing of the solenoid valve 601, adjusting the operation of the air supply unit, etc.; converting the control instructions into specific operations to ensure the accuracy of environmental control and resource management.

[0129] The feedback and monitoring module monitors the status and effect of each execution link, feeds back the actual operation results to the controller for further adjustment and optimization, adjusts the system parameters in real time, and ensures that the controller's decisions are consistent with the actual operation results.

[0130] The ratio calculation module calculates the ratio of the number of solenoid valves 601 closed due to unqualified growth status to the total number of planting positions, which is used to evaluate the overall improvement status of the plants in the cultivation room 101, help determine the performance of the entire cultivation room 101 under the current water stress conditions, and adjust the overall cultivation strategy.

[0131] The user interface and communication module provides a user operation and monitoring interface, displays system status, threshold settings, real-time data, alarm information, etc., and supports remote monitoring and communication, enhances the interaction between users and the system, enables users to view and adjust system parameters in real time, and supports data upload and system maintenance.

[0132] The security and priority management module manages the priorities of different instructions, such as the second instruction takes precedence over the first instruction, ensuring that the system can prioritize the execution of key instructions under abnormal circumstances. In addition, it is also responsible for detecting and responding to potential system failures or security issues to ensure the stability and security of the system and avoid waste of resources or erroneous operations.
