Description

Technical Field

[0001] This invention relates to the field of agricultural greenhouse cultivation technology, specifically to a smart greenhouse and cultivation method for optimizing the cultivation parameters of Polygonatum sibiricum. Background Technology

[0002] As a traditional medicinal and edible crop, Polygonatum rhizome is rich in active ingredients such as polysaccharides and saponins, possessing both medicinal and nutritional value, leading to a continuous increase in market demand. However, Polygonatum rhizome has a long growth cycle, typically 2 to 3 years, and has stringent specific requirements for its growing environment, especially light intensity, light transmittance gradient, temperature stability, and the precision of water and fertilizer supply, which directly affect its rhizome enlargement, accumulation of effective components, and plant survival rate.

[0003] In the current artificial cultivation of Polygonatum, the control methods for the aforementioned core environmental parameters are difficult to adapt to its growth requirements; the control of key cultivation parameters such as light, temperature, water and fertilizer lacks a linkage and matching mechanism, and the cultivation chambers do not have an independent control layout design, making it impossible to carry out single variable experiments and difficult to efficiently screen the optimal parameter combination suitable for the growth of Polygonatum. Summary of the Invention

[0004] The purpose of this invention is to provide a smart greenhouse and cultivation method for optimizing the cultivation parameters of Polygonatum sibiricum. It addresses the problems in existing technologies where the control of multiple parameters in Polygonatum sibiricum cultivation lacks a linkage and matching mechanism, the cultivation chambers lack independent control layout, and it is impossible to conduct single-variable experiments to screen the optimal combination of cultivation parameters. The invention proposes a solution that enables the linkage control of multiple parameters in Polygonatum sibiricum cultivation, supports the conduct of single-variable experiments, efficiently screens the optimal combination of cultivation parameters, and adapts to the environmental requirements for Polygonatum sibiricum growth.

[0005] This invention is achieved through the following technical solution: Firstly, a smart greenhouse for optimizing the cultivation parameters of Polygonatum sibiricum includes: a cultivation cabinet with a cultivation cavity at its top, the cultivation cavity being divided into multiple independent cultivation chambers; multiple light-transmitting covers, each corresponding to one of the cultivation chambers, each light-transmitting cover being detachably installed on the top of its corresponding cultivation chamber; multiple environmental detection components, each corresponding to one of the cultivation chambers, each environmental detection component being installed within its corresponding cultivation chamber; multiple environmental control components, each corresponding to one of the cultivation chambers, each environmental control component being installed within its corresponding cultivation chamber; and a control host connected to the multiple environmental detection components, the control host being able to independently control the environmental control components within each cultivation chamber based on the detection data from the environmental detection components.

[0006] Furthermore, in this invention, the aforementioned environmental detection components include: a light detection component, which is assembled inside the cultivation chamber and is used to detect the light intensity parameters inside the cultivation chamber in real time; a temperature detection component, which is installed inside the cultivation chamber and is used to detect the ambient temperature parameters inside the cultivation chamber in real time; and a humidity detection component, which is installed inside the cultivation chamber and is used to detect the air humidity parameters inside the cultivation chamber in real time.

[0007] Furthermore, in this invention, the aforementioned environmental control components include: a light control component installed in the cultivation chamber for real-time control of the light intensity inside the cultivation chamber; a temperature control component installed in the cultivation chamber for real-time control of the ambient temperature inside the cultivation chamber; and a humidity control component installed in the cultivation chamber for real-time control of the air humidity inside the cultivation chamber.

[0008] Furthermore, in this invention, the above-mentioned light adjustment component includes: a supplementary light unit installed in the cultivation chamber for increasing the light intensity inside the cultivation chamber; and a shading unit installed in the cultivation chamber for reducing the light intensity inside the cultivation chamber.

[0009] Furthermore, in this invention, the aforementioned shading unit includes: multiple shading curtains installed from top to bottom within the cultivation chamber, each shading curtain having a different light transmittance; and an actuator installed within the cultivation chamber, capable of controlling the pre-set shading curtains to unfold or fold; wherein the actuator can selectively control any shading curtain to unfold, thereby forming a shading cover on the light-transmitting cover plate, and simultaneously control the remaining shading curtains to fold and store.

[0010] Furthermore, in this invention, the aforementioned sunshade curtain body includes: two guide rods, which are installed parallel to each other on opposite sides of the cultivation chamber; a sliding crossbar, which is guided and installed between the two guide rods and can reciprocate along the extension direction of the guide rods; a sunshade curtain surface, one end of which is fixedly connected to the end between the two guide rods, and the other end of which is connected to the sliding crossbar; and a linkage joint, which is installed on the sliding crossbar and can be driven and engaged with an actuator; wherein, in the unfolded state, the actuator drives the linkage joint to move in a first direction, causing the sunshade curtain surface to unfold and form a full-coverage shading of the light-transmitting cover; in the folded state, the actuator drives the linkage joint to move in a second direction, causing the sunshade curtain surface to fold and retract.

[0011] Furthermore, in this invention, the lengths of the multiple linkage joints decrease sequentially from top to bottom, so that the ends of the multiple linkage joints that cooperate with the actuator are at the same vertical height; the multiple linkage joints are staggered in different positions in the horizontal direction, thereby avoiding transmission interference between adjacent linkage joints.

[0012] Furthermore, in this invention, the actuator includes: a longitudinal transmission module installed in the cultivation chamber; a transverse transmission module installed on the longitudinal transmission module; and a drive connector installed on the transverse transmission module; wherein the transverse transmission module can drive the drive connector to connect with the corresponding linkage connector, and the longitudinal transmission module can drive the drive connector to drive the linkage connector.

[0013] Furthermore, in this invention, an unfolding limiting member is installed on one side of the cultivation chamber, and a folding limiting member is installed on the other side of the cultivation chamber. The unfolding limiting member and the folding limiting member are respectively located on both sides of the light-transmitting cover. A docking slot is provided on the linkage connector, and at least one receiving channel is provided on the inner wall of the docking slot. A linkage block is guided in the receiving channel, and unfolding guide slope and folding guide slope are respectively provided on both sides of one end of the linkage block. An elastic member is installed in the receiving channel, one end of the elastic member is connected to the inner wall of the receiving channel, and the other end of the elastic member is connected to the linkage block. In the unfolded state, the top end of the drive connector pushes the unfolding guide slope, causing the sliding crossbar to abut against the unfolding limiting member. In the folded state, the top end of the drive connector continues to push the unfolding guide slope, driving the linkage block to retract into the receiving channel, so that the drive connector extends into the docking slot, and the folding guide slope engages with the bottom end of the drive connector. The bottom end of the drive connector pushes the folding guide slope, causing the sliding crossbar to abut against the folding limiting member.

[0014] Secondly, a method for optimizing the cultivation parameters of Polygonatum sibiricum, applied to a smart greenhouse for optimizing Polygonatum sibiricum cultivation parameters, includes the following steps: S1, planting Polygonatum sibiricum seedlings in multiple cultivation chambers, and detachably installing light-transmitting covers on the top of the cultivation chambers, ensuring that the environmental detection and environmental control components in each cultivation chamber are in working condition; S2, the control host independently controls the operation of the environmental control components in each cultivation chamber, applying differentiated cultivation parameters of light intensity, ambient temperature, and air humidity to each cultivation chamber, forming multiple sets of differentiated Polygonatum sibiricum cultivation experimental environments; S3, the environmental detection components in each cultivation chamber collect real-time data on light, temperature, humidity, and Polygonatum sibiricum growth status, and upload this data to the control host; S4, the control host compares and analyzes the light, temperature, humidity, and Polygonatum sibiricum growth status data, and selects and determines the optimal cultivation environment parameter thresholds suitable for each growth stage of Polygonatum sibiricum, thus completing the optimization of Polygonatum sibiricum cultivation parameters.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. This invention adopts a separate layout of multiple independent sealed cultivation chambers, independent environmental regulation components, and independent environmental detection components. This avoids experimental interference caused by heat exchange and water vapor diffusion between traditional cultivation chambers, fundamentally solving the problem of uncontrollable variables in the traditional regulation of Polygonatum cultivation parameters. At the same time, it ensures that the environment of each chamber is independent and controllable, significantly improving the scientific nature of parameter screening experiments and adapting to the parameter optimization needs of Polygonatum at multiple growth stages.

[0016] 2. This invention ensures that a single shade curtain completely covers the light-transmitting cover when unfolded and returns to its original position when folded by limiting the unfolding and folding components. Compared with the traditional method of controlling multiple layers of curtains, this invention completely avoids the problem of inaccurate light transmittance control caused by the accumulation of layering deviations, and ensures that the shading effect of a single curtain is controllable.

[0017] 3. This invention uses a multi-parameter collaborative prediction and control formula linked to the control host to achieve correlation prediction, deviation correction and fluctuation constraint of light, temperature and humidity. It eliminates the need for manual individual control of each parameter, solves the environmental imbalance problem caused by traditional single-parameter independent control, significantly reduces manual operation costs and control errors, promotes the enlargement of Polygonatum rhizomes and the accumulation of effective components, and improves cultivation quality.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention. Example

[0021] Please refer to Figures 1 to 8 This invention provides a smart greenhouse for optimizing the cultivation parameters of Polygonatum sibiricum. It includes a cultivation cabinet 1, multiple light-transmitting covers 3, multiple environmental monitoring components, multiple environmental control components, and a control host 4. The bottom of the cultivation cabinet 1 is equipped with several casters 5 for easy transfer to different locations according to experimental needs. Multiple independent cultivation chambers 6 are formed within the cultivation cavity 2 at the top of the cultivation cabinet 1, evenly spaced to ensure the fairness of experimental variable control. Each light-transmitting cover 3 corresponds to one of the cultivation chambers 6, and uses a snap-fit ​​detachable structure to quickly install, remove, and seal the top of the cultivation chamber 6, facilitating seedling planting and allowing for replacement of covers with different light transmittance properties as needed. The environmental monitoring components and environmental control components are each installed within one of the cultivation chambers 6. The environmental monitoring components are used to collect environmental parameters within the cultivation chambers 6 in real time. The control host 4 communicates with each environmental monitoring component and can independently control the operation of the corresponding environmental control components within the cultivation chamber 6 based on the monitoring data.

[0022] In the experiment to optimize the cultivation parameters of Polygonatum, the operator opened the light-transmitting cover 3 through a detachable structure, selected Polygonatum seedlings with consistent growth status (or seeds with the same genetic background) and planted them in each independent cultivation chamber 6, and then closed the light-transmitting cover 3; the operator then used the control host 4 to drive the environmental adjustment component to adjust the initial environmental parameters of each cultivation chamber 6 to a uniform baseline value; subsequently, the operator used the control host 4 to control the environmental adjustment component to adjust a single environmental parameter for each cultivation chamber 6 individually, so that there is only a gradient difference in a single parameter among the cultivation chambers 6, while the other parameters remain consistent, and carried out a single-factor variable cultivation experiment; each round of experiment focused on one parameter, and after completing the single-factor gradient experiment of core parameters such as light, temperature, water and fertilizer in sequence, the optimal growth adaptation value of Polygonatum corresponding to each parameter was selected.

[0023] After completing single-parameter optimization, the environmental parameters of each cultivation chamber 6 were synchronously adjusted to the optimal combination of each single parameter, and the growth performance of Polygonatum was observed. If growth deterioration occurred after parameter superposition, the researchers initiated a multi-parameter synergistic optimization experiment: using the optimal value of each single parameter as the baseline threshold, the core parameters such as light, temperature, water and fertilizer were adjusted according to preset gradients. Differentiated parameter combination control commands were issued to each cultivation chamber 6 through the control host 4. Utilizing the independent control function of each cultivation chamber 6, each cultivation chamber 6 corresponded to a unique set of parameter combinations, forming multiple sets of parameter combination controls. During the experiment, the environmental detection component continuously collected real-time environmental parameters of each cultivation chamber 6, and synchronously recorded growth indicators such as plant height, stem diameter, and accumulation of effective components of Polygonatum (collected by image acquisition equipment). After the experimental period, the growth data corresponding to each parameter combination were analyzed for correlation to locate the antagonistic effect range between parameters. Finally, the optimal combination range of synergistic adaptation between each parameter was selected to achieve precise matching of the growth environment of Polygonatum under multi-parameter coupling.

[0024] Each cultivation chamber 6 adopts a heat-insulating and sealed structure design. The partition walls between cultivation chambers 6 are made of high thermal conductivity and heat-insulating material in one piece. The walls of cultivation chambers 6 are covered with sealing strips. With the sealing structure of the light-transmitting cover plate 3, each cultivation chamber 6 can achieve an independent closed-loop environment. This effectively avoids the interactive interference such as heat exchange and water vapor diffusion that occurs between adjacent chambers during the environmental parameter control process, and ensures that the environmental parameter adjustment of each cultivation chamber 6 is independent.

[0025] Please refer to Figure 1 , Figure 2 and Figure 4In some embodiments of this application, the environmental monitoring component includes a light detection component, a temperature detection component, and a humidity detection component. All three components are installed within the cultivation chamber 6. The light detection component is used to collect real-time light intensity parameters within the cultivation chamber 6; the temperature detection component is used to collect real-time ambient temperature parameters within the cultivation chamber 6; and the humidity detection component is used to collect real-time air humidity parameters within the cultivation chamber 6. By using these three core environmental parameters—light, temperature, and air humidity—comprehensive monitoring of the growth environment of *Polygonatum sibiricum* within the cultivation chamber 6 is achieved.

[0026] Among them, the light detection component, temperature detection component and humidity detection component can respectively adopt photosynthetically active radiation sensor 25, temperature sensor 26 and humidity sensor 27. Each sensor establishes a communication connection with the control host 4, and can stably output detection signals of corresponding environmental parameters, adapting to the heat-insulated and sealed environment of the cultivation chamber 6 to complete all-weather monitoring.

[0027] In some embodiments of this application, the environmental control component includes a light control component, a temperature control component, and a humidity control component. The light control component, temperature control component, and humidity control component are all correspondingly installed in each cultivation chamber 6. The light control component is used to control the light intensity in the cultivation chamber 6 in real time, the temperature control component is used to control the ambient temperature in the cultivation chamber 6 in real time, and the humidity control component is used to control the air humidity in the cultivation chamber 6 in real time.

[0028] The light regulation component includes a supplementary light unit and a shading unit, both of which are installed inside the cultivation chamber 6. The supplementary light unit is used to increase the light intensity inside the cultivation chamber 6, while the shading unit is used to reduce the light intensity inside the cultivation chamber 6. Through the coordinated operation of supplementary light and shading, the light intensity inside the cultivation chamber 6 can be regulated.

[0029] For example, the shading unit includes several shading curtains and actuators. Each shading curtain is arranged vertically from top to bottom along the cultivation chamber 6. Each shading curtain is made of polyester fiber shading base fabric with different shading performance, and the light transmittance of each curtain shows a gradient difference. The actuator is installed in the cultivation chamber 6 and is connected to each shading curtain. According to the light control requirements, it can selectively control the opening of a specified shading curtain to form a complete shading coverage of the light-transmitting cover 3, and at the same time, it can link and control the other shading curtains to fold back in time, thereby realizing flexible adjustment of the light intensity in the cultivation chamber 6.

[0030] Please refer to Figure 4The supplemental lighting unit can use LED plant growth lamp group 28. The LED plant growth lamp group 28 is adapted to the spectral band required for the photosynthetic growth of Polygonatum sibiricum. It can realize graded supplemental lighting adjustment according to the light control needs of cultivation chamber 6, so as to meet the light supply requirements of Polygonatum sibiricum at different growth stages.

[0031] It should be noted that the shading unit consists of several shading curtains and actuators. The actuators selectively control the pre-set shading curtains to fully cover the light-transmitting cover 3. Compared with the existing cultivation method of using multi-layer shading components and adjusting the light transmittance by adding or removing layers, this method can effectively avoid the misalignment and offset problems that are easy to occur between multi-layer curtains, and avoid the accumulation of deviations caused by the increase of the number of superimposed layers. This solves the defects of the existing technology, such as the large deviation between the actual light transmittance and the target control value, the difficulty in achieving precise light control, and the inability to adapt to the light transmittance gradient requirements of different growth stages of Polygonatum.

[0032] Please refer to Figure 2 , Figure 4 and Figure 6 The sunshade curtain includes two guide rods 14, a sliding crossbar 21, a sunshade curtain surface, and a linkage joint 15. The two guide rods 14 are arranged in parallel on opposite sides of the cultivation chamber 6. The sliding crossbar 21 is guided and assembled between the two guide rods 14 and can move back and forth along the extension direction of the guide rods 14. The sunshade curtain surface is made of flexible material. One end of the sunshade curtain surface is fixed to the end position between the two guide rods 14, and the other end is fixedly connected to the sliding crossbar 21. The linkage joint 15 is assembled on the sliding crossbar 21 and can form a transmission cooperation with the actuator. When the sunshade curtain is in the unfolded state, the actuator drives the linkage joint 15 to move along the first direction, causing the sliding crossbar 21 to move synchronously, thereby driving the sunshade curtain to unfold and form a full-coverage shading of the light-transmitting cover 3; when in the folded state, the actuator drives the linkage joint 15 to move in the opposite direction along the second direction, and the sliding crossbar 21 is reset and drives the sunshade curtain to fold and close. Through the corresponding transmission between the actuator and the linkage joint 15 of each sunshade curtain, independent control of the movement state of different sunshade curtains can be achieved.

[0033] Several rings are evenly distributed on both sides of the sunshade curtain along its extension direction. Each ring is fitted onto the guide rods 14 on both sides. Through the sliding cooperation between the rings and the guide rods 14, the movement trajectory of the sunshade curtain can be effectively constrained, ensuring the stability of the sunshade curtain during the opening and closing process and improving the stability of the shading state.

[0034] It should be noted that the specific structural form of the sunshade curtain is not shown in the schematic diagram. This design is to prioritize the complete display of the guide rod 14, sliding crossbar 21, linkage joint 15, etc. of the sunshade curtain body, so as to avoid visual obstruction of the above key structures due to the coverage of the sunshade curtain, so as to present the assembly relationship and spatial layout of each component more intuitively.

[0035] Please refer to Figure 6 The lengths of the various linkage joints 15, distributed from top to bottom, decrease sequentially along the vertical direction, ensuring that the transmission ends of each linkage joint 15 that cooperate with the actuator are at the same vertical height. Simultaneously, the linkage joints 15 are arranged in a staggered manner in the horizontal direction, forming a misaligned horizontal positional relationship. Based on the vertically stacked layout of the various sunshade curtains, the actuator can drive different linkage joints 15 within the same horizontal plane. The equal-height design of the transmission ends, achieved through the decreasing vertical lengths of the linkage joints 15, combined with the staggered horizontal arrangement, ensures both transmission compatibility between the actuator and each linkage joint 15 and effectively avoids motion interference between adjacent linkage joints 15. This ensures that the actuator can independently drive different linkage joints 15 to move the corresponding sunshade curtain to complete the opening or closing action by adjusting its own horizontal position.

[0036] The actuator includes a longitudinal transmission module, a transverse transmission module, and a drive connector 17. The actuator is positioned below all the sunshade curtains. The longitudinal transmission module is installed inside the cultivation chamber 6, the transverse transmission module is mounted on the longitudinal transmission module, and the drive connector 17 is installed on the transverse transmission module. The transverse transmission module can drive the drive connector 17 to move laterally, achieving docking with different linkage connectors 15. After docking, the longitudinal transmission module can drive the transverse transmission module and the drive connector 17 to move longitudinally, thereby driving the linkage connectors 15 through the drive connector 17 to complete the opening or closing action of the corresponding sunshade curtain.

[0037] Please refer to Figure 2 , Figure 4 and Figure 6 Specifically, the longitudinal transmission module includes a longitudinal guide rod 7, a longitudinal lead screw 8, a longitudinal slide block 9, and a longitudinal motor 23. The longitudinal guide rod 7 and the longitudinal lead screw 8 are respectively located on opposite sides of the cultivation chamber 6. The longitudinal guide rod 7 passes through the longitudinal slide block 9 to form a guiding fit, and the longitudinal lead screw 8 passes through the longitudinal slide block 9 to form a threaded fit. The longitudinal motor 23 is mounted on the side wall of the cultivation chamber 6. The output shaft of the longitudinal motor 23 is connected to the longitudinal lead screw 8 for transmission. By driving the longitudinal lead screw 8 to rotate through the longitudinal motor 23, the longitudinal slide block 9 can be driven to reciprocate longitudinally, thereby driving the transverse transmission module mounted on the longitudinal slide block 9 to move synchronously longitudinally.

[0038] The transverse transmission module includes two mounting supports 10, a transverse guide rod 11, a transverse lead screw 12, a transverse slide 16, and a transverse motor 13. The two mounting supports 10 are respectively mounted on both sides of the longitudinal slide 9. The transverse guide rod 11 and the transverse lead screw 12 are parallel to each other between the two mounting supports 10. The transverse lead screw 12 is rotatably mounted on the mounting support 10. The transverse motor 13 is mounted on the longitudinal slide 9. The output shaft of the transverse motor 13 is connected to the transverse lead screw 12. The transverse slide 16 passes through both the transverse guide rod 11 and the transverse lead screw 12. The transverse slide 16 and the transverse guide rod 11 form a guiding fit. The transverse slide 16 and the transverse lead screw 12 form a threaded fit. The drive connector 17 is mounted on the transverse slide 16. By driving the transverse lead screw 12 to rotate through the transverse motor 13, the transverse slide 16 can be driven to reciprocate along the transverse guide rod 11.

[0039] Please refer to Figures 2 to 5 In some embodiments of this application, an unfolding limiting member 22 is installed on one side of the cultivation chamber 6, and a folding limiting member 29 is installed on the other side. The unfolding limiting member 22 and the folding limiting member 29 are respectively located on both sides of the light-transmitting cover plate 3. A docking groove 30 is formed on the linkage connector 15. At least one receiving channel 31 is formed on the inner wall of the docking groove 30. A linkage block 33 is guided and assembled in the receiving channel 31. An unfolding guide slope 34 and a folding guide slope 35 are respectively processed on both sides of one end of the linkage block 33. An elastic member 32 (spring) is also assembled inside the receiving channel 31. One end of the elastic member 32 is connected to the inner wall of the receiving channel 31, and the other end is fixedly connected to the linkage block 33. When the sunshade curtain is in the unfolded state, the top of the drive connector 17 pushes against the unfolding guide slope 34, causing the sliding crossbar 21 to move in the corresponding direction until the sliding crossbar 21 abuts against the unfolding limit member 22, thus achieving the full unfolding of the sunshade curtain. When the sunshade curtain is in the folded state, the top of the drive connector 17 continues to push against the unfolding guide slope 34, causing the linkage block 33 to retract into the receiving groove 31, so that the drive connector 17 can smoothly extend into the docking groove 30. At this time, the folding guide slope 35 of the linkage block 33 and the bottom end of the drive connector 17 form a locking engagement. The bottom end of the drive connector 17 further pushes against the folding guide slope 35, causing the sliding crossbar 21 to move in the opposite direction until it abuts against the folding limit member 29, thus completing the folding and closing of the sunshade curtain.

[0040] When the experimenter performs the control operation on the preset sunshade curtain, the drive joint 17 is first moved to the end position of the cultivation chamber 6 through the longitudinal transmission module. Then, the transverse transmission module is used to adjust the transverse position of the drive joint 17 so that the drive joint 17 is aligned with the preset linkage joint 15. Then, the longitudinal transmission module is controlled to drive the drive joint 17 to move longitudinally so that the drive joint 17 is engaged in the groove of the docking slot 30. Because the linkage block 33 is at least partially inserted into the docking slot 30 under the elastic force of the elastic element 32, the drive joint 17 can push the linkage block 33 to move longitudinally, causing the linkage joint 15 to move synchronously, thereby pulling the sliding crossbar 21 to move to realize the unfolding action of the sunshade curtain until the sliding crossbar 21 abuts against the unfolding limit element 22, and the sunshade curtain is fully unfolded. When it is necessary to retract the unfolded sunshade curtain, the experimenter continues to control the drive connector 17 to advance longitudinally. The drive connector 17 continuously presses against the unfolding guide slope 34 of the linkage block 33. The component force generated by this can drive the linkage block 33 to retract completely into the receiving channel 31, allowing the drive connector 17 to continue to move forward. After the drive connector 17 has completely passed through the linkage block 33, the elastic force of the elastic element 32 can drive the linkage block 33 to reset and form a locking engagement with the bottom end of the drive connector 17. At this time, by controlling the drive connector 17 to move in the reverse longitudinal direction, the bottom end of the drive connector 17 can push against the folding guide slope 35 to drive the linkage connector 15 to move in the reverse direction, pulling the sliding crossbar 21 to move synchronously until the sliding crossbar 21 abuts against the folding limit element 29, and the sunshade curtain is completely retracted. The experimenters continued to control the drive connector 17 to move in the opposite direction along the longitudinal direction, and the pressure it applied to the folding guide slope 35 gradually increased. The resulting component force could drive the linkage block 33 to retract completely into the receiving channel 31 again, and finally achieve the separation of the drive connector 17 from the docking slot 30.

[0041] Please refer to Figure 7 and Figure 8 It should be noted that the drive joint 17 can push the unfolded guide ramp 34 and the folded guide ramp 35 to drive the linkage joint 15 to move synchronously; after the sliding crossbar 21 abuts against the limiting member, the drive joint 17 is continued to be pushed forward in the abutment direction. The thrust applied by the drive joint 17 can be decomposed into a lateral component force. The lateral component force can overcome the elastic force of the elastic member 32, thereby driving the linkage block 33 to retract into the receiving channel 31.

[0042] Among them, the folding limiting member 29 is equipped with a magnetic suction member vertically from top to bottom, and the end of the sliding crossbar 21 is equipped with a corresponding magnetic guide member. When the sliding crossbar 21 is in the folded and retracted state, it can be adsorbed and positioned by the magnetic attraction of the magnetic suction member and the magnetic guide member, which effectively avoids the sunshade curtain from being unintentionally unfolded. Moreover, when the drive connector 17 pushes against the unfolding guide slope 34 of the linkage block 33, the elastic member 32 does not need to deform, and the magnetic attraction force can be directly overcome, so as to drive the sliding crossbar 21 to move smoothly.

[0043] It should be noted that several longitudinally arranged telescopic rods can be installed at the bottom of the sunshade curtain. One end of the telescopic rod is connected to the inner wall of the cultivation chamber 6, and the other end is fixedly connected to the sliding crossbar 21. The telescopic rod can extend synchronously with the unfolding of the sunshade curtain and shorten synchronously with the folding of the sunshade curtain. The telescopic rod provides support for the folded sunshade curtain, effectively avoiding structural interference caused by the drooping of the sunshade curtain after folding, and ensuring the normal operation of the actuator.

[0044] Please refer to Figure 2 and Figure 4 In some embodiments of this application, the temperature control component can be a combination of a heating and cooling coil 20 and a circulating fan 24 arranged on the side wall of the cultivation chamber 6, and the humidity control component can be an ultrasonic atomizing humidification module 19 installed in the cultivation chamber 6 and a dehumidification and exhaust structure 18 embedded in the side of the cultivation chamber 6. These components can respectively control the temperature and humidity inside the cultivation chamber 6, adapting to the temperature and humidity control requirements of Polygonatum cultivation. Furthermore, the cultivation chamber 6 has ventilation holes, which can form a compliant air circulation loop to meet the airflow exchange requirements for temperature and humidity control.

[0045] Secondly, Please refer to Figure 9 This invention provides a method for optimizing the cultivation parameters of Polygonatum sibiricum. The method includes the following steps: S1. Plant the Polygonatum sibiricum seedlings in multiple cultivation chambers 6, and detachably install the light-transmitting cover 3 on the top of the cultivation chamber 6, so that the environmental detection components and environmental control components in each cultivation chamber 6 are in working condition. Select uniformly growing Polygonatum seedlings and plant them in the preset cultivation positions in each cultivation chamber 6. The light-transmitting cover 3 is detachably assembled on the top of each cultivation chamber 6 to construct an independent and sealed cultivation experimental space. Simultaneously start the environmental detection components and environmental regulation components in each cultivation chamber 6 to ensure that the shading curtain and supplementary lighting unit of the light regulation component, the heat exchange coil 20 and circulating fan 24 of the temperature regulation component, the ultrasonic atomizing humidification module 19 and dehumidification exhaust structure 18 of the humidity regulation component, and the air control valve plate at the ventilation hole are all in the ready-to-regulate state. S2. The control host 4 independently controls the operation of the environmental regulation components in each cultivation chamber 6, and applies different cultivation parameters such as light intensity, ambient temperature and air humidity to each cultivation chamber 6 to form multiple sets of differentiated Polygonatum cultivation experimental environments. The control host 4 sends independent control commands to the environmental control components of each cultivation chamber 6. The actuator drives the shading curtains with different light transmittance to open or close, and coordinates with the supplementary lighting unit to achieve differentiated control of light intensity in each chamber. The heat exchange coil 20 of the temperature control component works in conjunction with the air supply of the circulating fan 24, and coordinates with the ventilation hole control valve plate to regulate airflow circulation, thereby achieving differentiated control of the ambient temperature of each cultivation chamber 6. Through the coordinated action of the ultrasonic atomizing humidification module 19 of the humidity control component and the dehumidification and exhaust structure 18, differentiated control of air humidity in each cultivation chamber 6 is achieved. Finally, multiple sets of differentiated Polygonatum cultivation experimental environments covering the dimensions of light, temperature and humidity are constructed in each cultivation chamber 6. S3. The environmental monitoring components in each cultivation chamber 6 collect the light parameters, temperature parameters, humidity parameters and growth status data of the corresponding cultivation chamber 6 in real time, and upload them to the control host 4. The environmental monitoring components in each cultivation chamber 6 continuously collect real-time light, temperature, and humidity parameters of the corresponding cultivation chamber 6, and simultaneously collect growth status data of the Polygonatum seedlings. After collection, the data of each type of parameter is uploaded to the control host 4 in real time through a preset data transmission link, and the control host 4 completes the classification, storage and preliminary organization of the data. S4 and the control host 4 compare and analyze the light parameters, temperature parameters, humidity parameters and growth status data of Polygonatum, screen and determine the optimal cultivation environment parameter thresholds suitable for each growth stage of Polygonatum, and complete the optimization of Polygonatum cultivation parameters. The control host 4 calls the preset data analysis model to conduct a correlation comparison analysis between the light, temperature, and humidity parameters corresponding to each experimental environment and the growth status data of Polygonatum. Combined with the growth physiological characteristics of Polygonatum, it completes the verification and elimination of abnormal data, selects the combination of environmental parameters that can ensure the healthy growth of Polygonatum, and then calibrates the optimal cultivation environment parameter thresholds that are suitable for each growth stage of Polygonatum, thus completing the optimization configuration of Polygonatum cultivation parameters.

[0046] In some embodiments of this application, the control host calls a multi-parameter collaborative prediction and control formula to analyze and process the collected data, and determines the optimal cultivation environment parameter thresholds suitable for each growth stage of Polygonatum. The multi-parameter collaborative prediction and control formula is as follows:

[0047] in, For the predicted value of the k-th type of environmental parameter, This is the baseline value for the k-th type of environmental parameter. , For the control coefficient, Let k be the time-varying change of the environmental parameter of type k. The data collection time interval For the collaborative weights between parameters, Let be the real-time value of the i-th type of associated environmental parameter. Let be the baseline value for the i-th type of associated environmental parameter. For parameters that deviate from the threshold, For parameter correction coefficients, (*) represents the variance of the predicted value. This is the variance control coefficient. This serves as the baseline value for parameter fluctuations.

[0048] For each cultivation chamber, the control host 4 sets the light, temperature, and humidity parameters (corresponding to k=1, 2, and 3 respectively). First, based on the baseline value of a certain type of parameter (taking temperature parameter k=2 as an example), the control host 4 first sets the parameters according to the baseline value of a certain type of parameter. Combined with the temperature change during the current period Acquisition interval with environmental monitoring components ,pass The project predicts the temperature's own changing trend, while also using... The real-time deviations of relative illumination (i=1) and humidity (i=3) are considered; for example, increased illumination may lead to a rise in temperature. In this case, the collaborative weighting is adjusted. It will amplify the effect of light deviation on temperature, and decreased humidity will exacerbate temperature fluctuations. This will incorporate the effect of humidity deviation, ultimately yielding a predicted temperature value for the next moment. This step involves "binding" and regulating three types of parameters to prevent adjusting any single parameter from disrupting the environmental balance of the cultivation chamber; if the predicted value is close to the baseline value... The difference exceeds the threshold This indicates that the temperature is about to deviate from the suitable range for Polygonatum, so the control unit calls the correction factor. The predicted value is then reversed to obtain the actual control value. The corresponding device's temperature regulation components will synchronously adjust the heat exchange power of the heating and cooling coils and the air supply intensity of the circulating fan to ensure the temperature returns to a suitable range; finally, through variance... Constrain the fluctuation range of the predicted values ​​to ensure that they do not exceed The corresponding threshold is used to avoid stressing the Polygonatum seedlings by sudden temperature changes and to adapt to the need for a stable growing environment for Polygonatum.
