Description

Technical Field

[0001] This invention relates to the field of plant cultivation simulation box technology, and specifically to an intelligent plant cultivation box for simulating abiotic stresses in plants. Background Technology

[0002] Salt-alkali stress is a common abiotic stress in agriculture, severely impacting plant growth and development. High salt concentrations in saline-alkali soils lead to water loss from plant cells, causing cell dehydration and physiological dysfunction, ultimately affecting normal plant growth and yield. Furthermore, salt-alkali stress alters the physical and chemical properties of the soil, affecting the activity of soil microorganisms and the health of plant roots. With the continuous expansion of saline-alkali land globally, salt-alkali stress has become a significant problem restricting sustainable agricultural development. Therefore, studying the effects of salt-alkali stress on plants and exploring effective coping strategies is of great scientific significance and practical value for improving crop salt tolerance, ensuring food security, and protecting the ecological environment.

[0003] In existing patent literature with patent publication number CN208354091U and patent title "A Device for Simulating Plant Growth Under Stress," it is specifically disclosed that "it includes a box, with several growth cells above the box to provide space for plant growth, several liquid storage cells below the box, nozzles inside the growth cells, and a seepage structure at the bottom of the growth cells, the seepage structure including a sponge layer and a seepage trough, the sponge layer covering the top of the seepage trough, a drain outlet at the bottom of the seepage trough, and the inner side of the growth cells being inclined, with the nozzles installed in the middle of the inner side, thus creating an environment close to that of growing in soil." However, the seepage structure of the above patent cannot actually simulate the real soil environment, and it has certain errors compared to the actual situation. In addition, some consumables cannot be reused, resulting in many drawbacks.

[0004] In existing patent literature with patent publication number CN212993381U and patent name "A Simulation Observation Device for Plant Stress Growth", it is specifically disclosed that "it includes a box body and a box cover set on the top of the box body. A spray plate is fixed at the bottom of the box cover. The water supply pipe of the spray plate passes through the box cover and is connected to the liquid storage tank. A water pump is provided on the water supply pipe. An air inlet pipe is provided on one side of the upper part of the side wall of the box body, and an air outlet pipe is provided on the other side. The air inlet pipe is connected to the air outlet of the blower. Several electric heating rods and semiconductor cooling chips are also provided in the middle part of the inner side wall of the box body. Multiple adjustable water filtration mechanisms are provided on the lower part of the side wall or the bottom wall, thereby simulating various adverse conditions that are not conducive to plant growth." However, the above patent can only simulate through spray equipment and cannot accurately control the salt and alkali concentration and pH value set by the soil and other substrates.

[0005] The patent, with publication number CN213991870U and titled "A Cabinet for Plant Stress Physiology," specifically discloses that "it includes an upper cabinet and a lower cabinet. The upper cabinet is divided into multiple test chambers with top openings by vertical partitions. Each test chamber is equipped with a vertical telescopic mechanism, a support plate, and a planting pot. The vertical telescopic mechanism is fixed to the bottom of the test chamber and can drive the support plate above it to rise and fall. The top surface of the support plate is equipped with multiple positioning blocks. The planting pot is placed on the top surface of the support plate. Each test chamber also has an openable and closable cover at its top opening. A plant growth light is installed on the lower surface of the cover. The lower cabinet contains a fan. The fan's air outlet is connected to the air inlet at the bottom of each test chamber through an air outlet pipe. Each test chamber has an exhaust vent on its upper rear wall." However, the above patent mainly studies the impact of drought, a single stress variable, on plant growth, and has certain shortcomings in dealing with other environmental variables such as salt and alkali stress.

[0006] The patent publication number is CN220000179U, and the patent name is a plant stress treatment device. It specifically discloses that "it mainly includes a cabinet, several laboratories, a control room and several planting pots. The planting pot has a planting trough and a liquid cavity around the planting trough. It mainly injects liquid into each liquid cavity through a pump, a multi-port pipe and a liquid inlet pipe. The liquid can be sent to the planting trough through the water passage and absorbed by the sponge. The substrate on the filter screen can absorb the liquid on the sponge. The sponge can continuously absorb the liquid, thereby avoiding direct spraying of liquid onto the plant leaves." However, the sponge substrate used in the above patent may not be suitable for the growth of all plants, and it cannot accurately simulate the actual salt and alkali stress environment.

[0007] In summary, this study developed an intelligent plant cultivation box to simulate abiotic stress in plants. This box accurately simulates the actual salt-alkali stress environment in the laboratory, while simultaneously regulating plant growth factors such as salt concentration, temperature, humidity, and light during the growth process. Furthermore, it can rapidly record plant growth status. This research has significant scientific and practical value for studying the impact of salt-alkali stress on plants, thereby improving crop salt tolerance, ensuring food security, and protecting the ecological environment.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1

[0050] Reference Figure 1 A smart plant cultivation box for simulating abiotic stress in plants includes a cultivation box body 5, and a cultivation module 7, a lighting and spraying module 10, a regulated power supply 2, a central controller 3, a cooling module 4, a temperature sensor 8, a control panel 13, a heating module 14, a metering pump 15, and a reagent tank 16 installed inside the cultivation box body 5. It should be noted that the regulated power supply 2 inside the smart plant stress cultivation box can provide power to each device.

[0051] Specifically, the bottom of the incubator shell 5 is equipped with four casters 1 to facilitate the movement of the entire incubator shell 5; the central controller 3 is located at the bottom of the incubator shell 5 and is connected to the control panel 13. The control panel 13 is located in the center of the incubator door 11 and can be used to set different culture conditions and related parameters; the incubator door 11 is hinged to the front of the incubator shell 5.

[0052] Reference Figure 1 The cooling module 4 and the heating module 14 are both located at the bottom of the incubator. They are connected to the cold air outlet 9 and the hot air outlet 12 at the top of the chamber through ventilation ducts, respectively, to realize real-time temperature control of the incubator 5. Both the cooling module 4 and the heating module 14 are connected to the central controller 3, which can realize intelligent control.

[0053] Furthermore, the temperature sensor 8 is connected to the central controller 3, which can detect the temperature inside the incubator in real time, and maintain the temperature inside the incubator 5 within the set value range by adjusting the operation of the cooling module 4 and the heating module 14 according to the set value.

[0054] Reference Figure 1 and Figure 2 The culture module 7 contains three vertically equidistant culture units 708. It should be noted that the number of culture units 708 depends on the size of the culture module 7 and the actual needs. This application does not limit the number of culture units 708, but only provides one embodiment. This application takes three culture units 708 as an example. The three culture units 708 are independent of each other and can carry out different experiments. Each culture unit 708 is equipped with a nylon mesh material box 706, which is a quick-replaceable structure, making it convenient to select different culture media to carry out corresponding experiments.

[0055] A collection tank 703 is provided directly below the culture unit 708. The bottom of the collection tank 703 is connected to a collection pipe 702, which is connected to a liquid detection module 711 located inside the culture module 7. A solenoid valve 701 is also installed at one end of the collection pipe 702 near the liquid detection module 711. A cleaning pipe 704 is provided inside the culture unit 708 and on one side of each culture unit 708. The cleaning pipe 704 can be connected to a metering pump 15 and a reagent tank 16 located at the bottom of the culture chamber 5.

[0056] Furthermore, refer to Figure 6The nylon mesh container 706 contains plant culture medium, and a breeding tray 710 is placed directly above the medium. The breeding tray 710 includes a seed tray 7101, a connecting bracket 7102, a breeding tray unit 7103, a support rod 7104, and a plant support frame 7105. The seed tray 7101 is connected to the breeding tray unit 7103 through multiple connecting brackets 7102. The plant support frame 7105 is placed on the support rod 7104. The breeding tray 710 includes three breeding tray units 7103. The number of breeding tray units 7103 is the same as the number of culture units 708. Therefore, this application also takes three breeding tray units 7103 as an example. They can be connected in series as a whole by splicing according to the experimental design requirements.

[0057] When cultivating plants, seeds can be placed on each seed tray 7101 at once, and pressing the seed tray 710 will press the lower part of the seed tray into the substrate below, thus quickly completing the planting of plants, thereby reducing repetitive planting work, improving work efficiency, and saving time.

[0058] Furthermore, refer to Figure 2 The cultivation module 7 is equipped with eight intelligent supports 707. It should be noted that the number of intelligent supports 707 depends on the actual needs and is not limited in this application. Only one implementation method is given. This application describes the method with eight intelligent supports 707.

[0059] Reference Figure 3 Each intelligent support 707 includes a first electric lifting rod 7071, a support 7072, and a fixing ring 7073. The support 7072 is connected to the top of the first electric lifting rod 7071 via the fixing ring 7073. During use, the number of supports 7072 can be increased or decreased according to actual needs, and the angle of the supports 7072 can be adjusted. The main function of the support 7072 is to connect the plant support frame 7105. Under the action of the first electric lifting rod 7071, the plant support frame 7105 can be raised and lowered. The first electric lifting rod 7071 is connected to the central controller 3. The central controller 3 will automatically adjust the height position of the plant support frame 7105 through the first electric lifting rod 7071 based on the plant height information measured by the intelligent ranging module 709, thereby achieving the plant support function.

[0060] Reference Figure 4The top of the cultivation module 7 is provided with a series of interconnected moving tracks 705, and the intelligent ranging module 709 can move on the moving tracks 705. The intelligent ranging module 709 includes a support foot 7091, a base plate 7092, a second electric lifting rod 7093, a ranging unit 7094, a photography unit 7095, a support frame 7096, a fixing ring 7097, an electric pulley 7098, and a rubber ring 7099. The intelligent ranging module 709 has four support feet 7091, which are fixed at the four corners of the base plate 7092 to support the base plate 7092. The second electric lifting rod 7093, the ranging unit 7094, the imaging unit 7095, and the electric pulley 7098 are all connected to the central controller 3. Therefore, the central controller 3 can control the automatic lifting of the second electric lifting rod 7093, and the data measured by the ranging unit 7094 and the imaging unit 7095 can be sent to the central controller 3 for analysis and processing. The central controller 3 can also control the operation of the electric pulley 7098.

[0061] Furthermore, a pair of electric pulleys 7098 are provided on the base plate 7092. The electric pulleys 7098 are connected to the central controller 3. The electric pulleys 7098 are equipped with rubber rings 7099. The function of the rubber rings 7099 is to enhance the friction when moving. Under the control of the central controller 3, they can move on the moving track 705 to record relevant information of crops in different cultivation units. The ranging unit 7094 and the imaging unit 7095 are fixed on the support frame 7096. The support frame 7096 is connected to the second electric lifting rod 7093 through the fixing ring 7097.

[0062] Furthermore, the ranging unit 7094 has an opening facing downwards, primarily used to measure the distance between the intelligent ranging module 709 and the top of the substrate inside the nylon mesh loading box 706. The opening direction of the photographing unit 7095 is perpendicular to the opening direction of the ranging unit 7094 and faces the crop. It is mainly used to record the growth status of the crop. At the same time, under the internal program analysis of the central controller 3, the second electric lifting rod 7093 is controlled to move up and down, so that the ranging unit 7094 is parallel to the highest point of the crop, thereby facilitating the recording of information such as the growth height of the crop. It can also adjust the distance from the LED light panel 104 on the top of the box to the top of the plant, thereby strictly controlling the light intensity received by the crop.

[0063] Reference Figure 1At the bottom of the culture chamber 5, a metering pump 15 and a reagent tank 16 are also provided. The metering pump 15 and the reagent tank 16 are connected. The reagent tank is divided into a clean water tank and a reagent tank. Specifically, one end of the metering pump 15 is connected to the reagent tank in the reagent tank 16, and the other end is connected to the drug delivery pipeline 102 in the lighting and spraying module 10. Through the set parameters on the control panel 13, the solution in the reagent tank is quantitatively and evenly sprayed onto each culture unit 708 in the culture module 7 through the nozzle 103. Therefore, the metering pump 15 is connected to the central controller 3 and is turned on and off by the central controller 3. The metering pump 15 can also be connected to the clean water tank in the reagent tank 16, and then the other end is connected to the drug delivery pipeline 102 and the cleaning pipe 704 in the culture module 7 to clean the substrate.

[0064] Furthermore, the central controller 3 can also open the solenoid valve 701 in the culture module 7, allowing the liquid collected in the collection tank 703 of each culture unit 708 to be transported to the liquid detection module 711 through the collection pipeline 702, thereby detecting the salt concentration in the culture substrate in the nylon mesh loading box 706 in real time. Secondly, this application can also use a second salt solution addition method through the program setting on the control panel 13. Under the control of the central controller 3, the metering pump 15 works continuously, continuously delivering the reagent in the reagent tank 16 until the salt concentration detected in the liquid detection module 711 meets the experimental parameter setting value. At this time, the metering pump 15 stops working, and the solenoid valve 701 closes, forming a closed environment with only the top opening in a single culture unit 708, thereby meeting the requirements of the experimental design.

[0065] Reference Figure 1 and Figure 5 The control panel 13 has a cleaning mode. When a single culture unit 708 finishes its culture experiment, cleaning can be performed to reset the salt content of the substrate in the nylon mesh loading box 706 to zero. This is mainly accomplished through the cleaning pipes 704 on both sides of the culture unit 708 and the nozzles 103 in the lighting and spray module 10. During the cleaning operation, the control panel 13 controls the lifting bracket 101 on the lighting and spray module 10 to extend above the culture unit 708. The metering pump 15 pumps water from the clean water tank in the reagent tank 16. At the same time, the cleaning work is carried out through the cleaning pipes 704 and the nozzles 103 in the lighting and spray module 10 to clean the substrate. The waste liquid from the cleaning enters the liquid detection module 711 through the collection tank 703 and the collection pipe 702, and then is discharged. When the liquid detection module 711 detects that the salt content in the waste liquid has decreased to the level of clean water, the cleaning operation is stopped.

[0066] It should be noted that the software and corresponding control equipment involved in this application all adopt existing technologies.

[0067] Example 2

[0068] The working mode and specific implementation method of this embodiment are basically the same as those of embodiment 1. The only difference is that in this embodiment, the plant stress mode under flooding can be selected through the control panel 13. In this mode, based on the simulated rainfall input by the system, the central controller 3 controls the metering pump 15 to evenly spray the clean water in the clean water tank of the reagent tank 16 into the cultivation unit 708 through the nozzles 103 in the lighting and sprinkler module 10, thereby simulating the plant stress under flooding conditions. It should be noted that replacing the clean water in the reagent tank 16 with simulated acid rain can simulate the plant stress under acid rain.

[0069] Example 3

[0070] The working mode and specific implementation method of this embodiment 3 are basically the same as those of embodiment 1. The only difference is that in this embodiment, the plant stress mode of high temperature, low temperature or sun exposure can be selected through the control panel 13. In the corresponding mode, the cooling module 4 and the heating module 14 can be set to work through the central controller 3 respectively. Combined with the real-time feedback of the temperature sensor 8, the temperature in the stress chamber is strictly controlled to form the corresponding high temperature or low temperature plant stress. At the same time, the light intensity of the LED light panel 104 in the lighting and spraying module 10 can be controlled through the central controller 3 to simulate the plant stress environment of sun exposure.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
