Description

Technical Field

[0001] The present invention relates to the technical field of rice cultivation, and particularly relates to an intelligent cultivation device for disease-resistant rice. Background Art

[0002] As one of the main food crops in China, the yield and quality of rice are crucial for ensuring national food security. However, during the rice planting process, pests and diseases are an issue that cannot be ignored. Pests and diseases such as rice blast and sheath blight not only lead to a reduction in rice yield, but in severe cases, even result in a complete crop failure, wasting food resources and severely dampening the enthusiasm of farmers. Therefore, cultivating disease-resistant rice has become an effective way to solve this problem. Disease-resistant rice enhances its own resistance to pests and diseases through genetic improvement or traditional breeding methods, thereby reducing the amount of pesticides used, lowering production costs, and at the same time increasing the yield and quality of rice.

[0003] During the cultivation process of disease-resistant rice, inoculating the rice seedlings with pathogenic bacteria to observe their disease-resistant reactions is a key technical step. However, the existing pathogenic bacteria inoculation technology has the following defects: 1. When transplanting rice seedlings, the existing devices lack the function of automatically and precisely adding pathogenic bacteria to the roots of the rice seedlings. This results in the need to rely on additional equipment or manual steps to complete the inoculation of pathogenic bacteria in actual operation, which not only increases the complexity of the operation but also raises the time cost; 2. In the technology of adding pathogenic bacteria during the cultivation process of disease-resistant rice, due to the lack of a precise control mechanism, the addition of pathogenic bacteria is often uneven or excessive, and since it is impossible to precisely adjust the inoculation amount of pathogenic bacteria according to the growth trend of the rice seedlings, some rice seedlings may not achieve the expected research or production effect due to too little inoculated pathogen, while some rice seedlings may be damaged due to too much inoculated pathogen; 3. During the process of transplanting and inoculating the roots of rice seedlings with pathogenic bacteria, the existing technology often easily causes damage to the roots of the rice seedlings. This kind of damage not only affects the growth rate of the rice seedlings but may also lead to a decrease in the resistance of the rice seedlings to pathogenic bacteria, thereby affecting the screening and cultivation effects of disease-resistant rice. To solve the problems existing in the inoculation of pathogenic bacteria in the existing cultivation of disease-resistant rice, there is an urgent need to propose an intelligent cultivation device for disease-resistant rice. Summary of the Invention

[0004] To solve the above problems, the present invention provides an intelligent cultivation device for disease-resistant rice. While protecting the roots of the rice seedlings through the airbag assembly, it can also judge the growth trend by the diameter of the roots of the rice seedlings squeezing the airbag assembly, and then automatically inoculate the original pathogenic bacteria solution according to the growth situation of the rice seedlings to achieve intelligent operation.

[0005] To achieve the above object, the technical solution of the present invention is as follows: A disease-resistant rice intelligent cultivation device includes a cultivation box with an open top. The cultivation box is signal-connected to a controller. A number of partitions are provided inside the cultivation box, and the partitions divide the interior of the cultivation box into several cultivation zones for cultivating rice. Inside the cultivation zones, a number of cultivation components are provided for automatically transporting the original pathogen solution according to the growth of rice and protecting the roots of the rice. Each cultivation component includes a cultivation tank. Inside the cultivation tank, a liquid component for filling the original pathogen solution and a transport component for transporting the original pathogen solution to the rice in the cultivation zone are respectively provided. The liquid component is connected to the transport component. On one side of each cultivation tank, a clamping component is fixedly connected. The clamping component is used for clamping and fixing the roots of the rice. On the inner side walls of the clamping components, airbag components for protecting the roots of the rice are provided. On the clamping components, first spraying components for spraying the original pathogen solution on the roots of the rice are provided. The first spraying components are all connected to the transport component. On the tops of the liquid components, second spraying components for spraying the original pathogen solution on the leaves of the rice are fixedly connected. The transport component and the second spraying components are both signal-connected to the controller. The airbag component is extruded as the root diameter of the rice grows, causing the gas inside the airbag component to enter the transport component. The transport component periodically transports the original pathogen solution to the first spraying component and the second spraying component according to the gas entering its interior for inoculating the rice with the pathogen.

[0006] The technical principle of the above solution is as follows: By planting rice seedlings of different disease-resistant varieties in different cultivation zones or conducting a control experiment. Each cultivation component in each cultivation zone acts on a single rice seedling. Place the cultivation tank on one side of the rice seedling, fill the original pathogen solution into the liquid component, and clamp the roots of the rice seedling with the clamping component. The airbag component is filled with air and connected to the transport component.

[0007] During the natural growth of the rice seedling, since the root diameter of the rice seedling gradually becomes larger, the airbag component is extruded and deformed as the roots of the rice seedling grow, causing the internal gas to enter the transport component. The transport component periodically transports the original pathogen solution to the first spraying component according to the amount of gas entering its interior, realizing the spraying on the roots of the rice seedling. And the controller transports the original pathogen solution to the second spraying component according to the amount of gas in the transport component, realizing the spraying at the leaves of the rice seedling.

[0008] The beneficial effects of adopting the above solution are as follows: 1. In this solution, the airbag assembly not only provides necessary protection for the rice roots to prevent damage during growth, but also indirectly reflects the growth trend of the rice through the degree of its extrusion and deformation. The gas released by the extrusion of the airbag assembly drives the conveying assembly, realizing the automatic adjustment of the conveying amount and spraying frequency of the original pathogen solution according to the growth conditions of the rice. This intelligent operation method not only improves the inoculation efficiency, but also ensures that the original pathogen solution can accurately act on the key growth parts of the rice.

[0009] 2. In this solution, the device can cultivate multiple rice varieties with disease resistance at the same time, or compare the disease resistance of different varieties through control experiments. This helps researchers quickly screen out rice varieties with strong disease resistance and good growth, providing strong support for the popularization and planting of disease-resistant rice.

[0010] 3. In this solution, through the intelligent controller, the device can accurately control the dosage of the original pathogen solution, avoiding waste of resources. At the same time, the design of the cultivation partition also enables each rice variety to obtain a suitable growth environment and nutrient supply, further improving the resource utilization efficiency; the adoption of an automated and intelligent operation method greatly simplifies the cumbersome steps in traditional rice cultivation.

[0011] Furthermore, the liquid components all include a liquid tank fixedly connected to the side wall of the cultivation tank. There is a filling port on the side wall of the liquid tank that communicates with the outside of the cultivation tank. There are several original liquid pipes for filling different original pathogen solutions in the liquid tank. The bottoms of the original liquid pipes are all connected to a first conveying pipe. A mixing pump is fixedly connected to the bottom of the liquid tank. The first conveying pipes are all connected to the mixing pump. The mixing pump is connected to the conveying assembly and is in signal connection with the controller.

[0012] Beneficial effects: The filling port opened at the top of the liquid tank communicates with the outside of the cultivation tank, which enables researchers to conveniently fill or supplement the original pathogen solution into the liquid tank from the outside, not only meeting the requirements for different original pathogen solutions in the process of screening and cultivating disease-resistant rice, but also improving the applicability of the device; the first conveying pipes connected to the bottom of the liquid tank are connected to the conveying assembly, ensuring that the original pathogen solution can be stably and continuously conveyed to the spraying assembly; the mixing pump mixes the original pathogen solutions in different original liquid pipes, ensuring that the concentration and type of the original pathogen solution can be adjusted according to actual needs, and one or more original pathogen solutions can be conveyed for the disease resistance test of rice seedlings, improving the accuracy and flexibility of inoculation.

[0013] Furthermore, each conveying assembly includes a conveying channel fixedly connected to the inner bottom wall of the cultivation tank. The inside of the conveying channel is in the shape of an hourglass. A liquid inlet is formed on one side of the conveying channel. The liquid inlet and the liquid mixing pump are both connected to a second conveying pipe. A conveying port is formed on the side of the conveying channel away from the liquid inlet, and the conveying ports are respectively connected to the corresponding first spraying assemblies. Gas ports communicating with the airbag assemblies are formed at the tops of the conveying channels; A telescopic assembly is fixedly connected to the bottom of each conveying channel. The telescopic assembly is normally located on one side of the conveying port. Gas is discharged from the airbag assembly and enters the conveying channel through the gas port. The gas in the conveying channel compresses the telescopic assembly, sucking the liquid in the stock solution pipe into the conveying channel and then entering the first spraying assembly to spray the rice, realizing the inoculation of pathogenic bacteria on the rice.

[0014] Beneficial effects: The conveying assembly utilizes the gas released by the airbag assembly as it is squeezed and deformed with the growth of the rice roots. The gas enters the conveying channel through the gas port and compresses the telescopic assembly, thereby sucking the pathogenic bacteria stock solution in the stock solution pipe into the conveying channel, realizing the automatic adjustment of the conveying amount of the pathogenic bacteria stock solution according to the growth of the rice, ensuring the accuracy and effectiveness of the inoculation; through intelligent adjustment of the conveying amount, the waste and overuse of the pathogenic bacteria stock solution are avoided.

[0015] Furthermore, the telescopic assembly includes a telescopic rod and a piston block. The piston block divides the conveying channel into an upper channel and a compression channel, and a check valve is provided at the bottom end of the upper channel; The telescopic rod is located in the compression channel and is fixedly connected to the bottom of the conveying channel. The piston block is fixedly connected to the top of the telescopic rod. A spring is sleeved on the telescopic rod, and the two ends of the spring are respectively fixedly connected to the bottom of the piston block and the bottom of the conveying channel. The piston block is located on one side of the conveying port.

[0016] Beneficial effects: The gas released by the airbag assembly compresses the spring and the telescopic rod, thereby pushing the piston block to move in the conveying channel. After the gas enters the compression channel through the gas port, it compresses the spring and pushes the piston block to move. In this process, the energy of the gas is efficiently converted into the kinetic energy of the piston block, thereby driving the conveying of the pathogenic bacteria stock solution, realizing the precise control of the conveying amount of the pathogenic bacteria stock solution according to the growth of the rice, and ensuring the accuracy and automation of the inoculation.

[0017] Furthermore, a first fixing rod is fixedly connected to one side of the telescopic rod. A contact is provided on the first fixing rod. A copper sheet is fixedly connected to one side of the inner wall of the compression channel close to the contact. A DC power supply is also provided in the compression channel. The DC power supply is signal-connected to the controller. The copper sheet is circuit-connected to the positive electrode of the DC power supply, and the contact is circuit-connected to the negative electrode of the DC power supply. The contact and the copper sheet can contact and slide cooperatively. When the contact contacts the copper sheet, the circuit loop is closed, and the current flowing from the contact through the copper sheet of the DC power supply cannot reach the threshold value set by the controller. Therefore, the controller determines that the piston block has not been pressed to the lowest point; when the contact touches the bottom of the copper sheet, the path of the DC power supply flowing from the contact through the copper sheet is the shortest, and the current reaches the threshold value set by the controller. At this time, the controller determines that the piston block has been pressed to the lowest point. When there is no contact between the contact and the copper sheet, the loop is disconnected, and a limiting block for restricting the position of the contact is provided at the bottom of the copper sheet; A closed loop is formed by the DC power supply, the contact and the copper sheet, which can transmit signals to the controller and control the second spraying assembly to spray the rice leaves through the controller.

[0018] Beneficial effects: When the gas released by the airbag assembly compresses the telescopic rod, the contact will slide and contact the copper sheet as the telescopic rod moves. During this process, the contact state between the contact and the copper sheet can reflect the magnitude of the gas pressure in real time, thereby realizing the real-time monitoring of the gas pressure. When the telescopic rod is compressed by the gas, the contact moves with the telescopic rod and contacts the copper sheet to form a closed loop. This signal is transmitted to the controller, and the controller starts the second spraying assembly to spray the rice leaves. This design realizes the intelligent control of the spraying process and improves the accuracy and efficiency of inoculation.

[0019] Furthermore, the clamping assembly includes a hollow second fixing rod fixedly connected to one side of the lower part of the cultivation tank. A fixing clip is fixedly connected to the end of the second fixing rod away from the cultivation tank. The fixing clip is signal-connected to the controller. The input end of the second fixing rod is communicated with the conveying port, and the output end of the second fixing rod is communicated with the first spraying assembly; The pipe diameter gradually decreases from the second conveying pipe to the second fixing rod.

[0020] Beneficial effects: The pathogen stock solution can be stably conveyed to the first spraying assembly through the hollow second fixing rod to achieve precise spraying on the roots of the rice seedlings. By clamping the roots of the rice seedlings with the fixing clip, it not only plays a role in fixing the growth of the rice seedlings and protecting their roots from being damaged by external forces, but also ensures that the pathogen stock solution sprayed from the first spraying assembly will not overflow in large quantities to pollute other rice seedlings.

[0021] Furthermore, the first spraying assembly includes a first nozzle fixedly connected to the second fixing rod. The input end of the first nozzle is communicated with the output end of the second fixing rod.

[0022] Beneficial effects: The design of the first spray head enables the original pathogen solution to be sprayed onto the rice in the form of uniform and fine droplets, improving the accuracy and uniformity of inoculation, and helping to ensure that the original pathogen solution can fully cover the roots of the rice seedlings, thereby improving the inoculation effect.

[0023] Furthermore, the airbag assembly includes airbags symmetrically arranged and fixedly connected to the inner side walls of the fixing clips. Air pipes are connected to the airbags, and the air pipes are all connected to the gas ports and are fixedly connected to both sides of the second fixing rod.

[0024] Beneficial effects: The airbags in the airbag assembly are symmetrically arranged on the inner side walls of the fixing clips. This design ensures that the original pathogen solution can evenly cover the roots of the rice seedlings during spraying. The symmetric airbags can exert pressure on both sides simultaneously when inflated, making the spraying more uniform and avoiding poor inoculation effects caused by uneven spraying; the airbags have a certain buffering effect when inflated, which can absorb part of the impact force generated by the air pressure change and avoid damage to the roots of the rice seedlings.

[0025] Furthermore, the second spraying assembly includes a hollow third fixing rod fixedly connected to one side of the top of the cultivation tank. The input end of the third fixing rod is connected to the liquid tank. A liquid pump is provided on the third fixing rod, and the liquid pump is signal-connected to the controller. The end of the third fixing rod far from the cultivation tank is fixedly connected to a second spray head, and the input end of the second spray head is connected to the output end of the third fixing rod.

[0026] Beneficial effects: By contacting the copper sheet through the contact point to start the liquid pump, the liquid pump can extract the original pathogen solution in the liquid tank to inoculate the pathogen on the leaf parts of the rice seedlings, improving the inoculation efficiency.

[0027] Furthermore, adjustment components are provided in each cultivation partition. The adjustment components include temperature and humidity sensors fixedly connected to the partition boards and third spray heads fixedly connected to the tops of the partition boards. The input ends of the third spray heads are all connected to water pipes, and the ends of the water pipes far from the third spray heads are connected to a water tank. Water pumps are provided on the water pipes, and several heating wires are provided in the partition boards. The temperature and humidity sensors, water pumps, and heating wires are all signal-connected to the controller.

[0028] Beneficial effects: The temperature and humidity sensors can monitor the temperature and humidity in the cultivation partition in real time, ensuring that the rice grows in the most suitable environmental conditions. This real-time monitoring and feedback mechanism enables the controller to adjust the environmental parameters in a timely manner to meet the growth requirements of the rice; through the controller, the heating wires can precisely adjust the temperature in the cultivation partition, and the water pumps can control the spraying amount of the third spray heads, thereby adjusting the humidity. This precise control makes the adjustment of environmental parameters more timely and accurate, helping to improve the growth quality and disease resistance of the rice.

[0035] The following will be further described in detail through specific embodiments: Embodiment 1:

[0036] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 : A disease-resistant rice intelligent cultivation device includes a cultivation box 1 with an open top. The cultivation box 1 is signal-connected to a controller. A plurality of partition plates 4 are provided in the cultivation box 1. The partition plates 4 divide the interior of the cultivation box 1 into a plurality of cultivation zones 2 for cultivating rice. A plurality of cultivation components for automatically conveying the original pathogen solution and protecting the roots of the rice according to the growth conditions of the rice are provided in each cultivation zone 2.

[0037] Each cultivation component includes a cultivation tank 6. A liquid component for filling the original pathogen solution and a conveying component for conveying the original pathogen solution to the rice in the cultivation zone 2 are respectively provided in the cultivation tank 6. The liquid component is communicated with the conveying component. A clamping component for clamping and fixing the roots of the rice is fixedly connected to one side of each cultivation tank 6. An airbag component for protecting the roots of the rice is provided on the inner side wall of the clamping component. A first spraying component for spraying the original pathogen solution on the roots of the rice is provided on each clamping component. The first spraying component is communicated with the conveying component. A second spraying component for spraying the original pathogen solution on the rice leaves is fixedly connected to the top of each liquid component. The conveying component and the second spraying component are both signal-connected to the controller.

[0038] The airbag component is squeezed by the root diameter during the growth of the rice, so that the gas in the airbag component enters the conveying component. The conveying component irregularly conveys the original pathogen solution to the first spraying component and the second spraying component according to the gas entering the interior for inoculating the rice with the pathogen.

[0039] The liquid component includes a liquid tank 16 fixedly connected to the inner side wall of the cultivation tank 6. A filling port 14 communicating with the outside of the cultivation tank 6 is provided on the side wall of the liquid tank 16. A number of stock solution pipes for filling different pathogenic bacteria stock solutions are provided in the liquid tank 16. The bottoms of the stock solution pipes are all connected to a first delivery pipe. A mixing pump 17 is fixedly connected to the bottom of the liquid tank 16. The first delivery pipes are all connected to the mixing pump 17. The mixing pump 17 is connected to the delivery component and is in signal connection with the controller. Through the mixing pump 17, one kind of pathogenic bacteria stock solution or the pathogenic bacteria stock solutions in different stock solution pipes can be mixed and transported for the disease resistance test of rice seedlings, improving the flexibility of inoculation.

[0040] The delivery components all include a delivery channel 19 fixedly connected to the inner bottom wall of the cultivation tank 6. The inside of the delivery channel 19 is in the shape of an hourglass. Liquid inlets are provided on one side of the delivery channel 19. Second delivery pipes 18 connecting the liquid inlets and the mixing pump 17 are provided. A delivery port 21 is provided on the side of the delivery channel 19 away from the liquid inlet. The delivery ports 21 are respectively connected to the corresponding first spraying components. Gas ports communicating with the airbag components are provided on the tops of the delivery channels 19.

[0041] Retractable components are fixedly connected to the inner bottoms of the delivery channels 19. The retractable components are normally located on one side of the delivery port 21. The retractable components include a telescopic rod 24 and a piston block 22. The piston block 22 divides the inside of the delivery channel 19 into an upper channel 23 and a compression channel 20. A check valve is provided at the bottom end of the upper channel 23. The check valve only allows gas to enter the chamber below the check valve in the upper channel 23 from the upper channel 23. The telescopic rod 24 is located in the compression channel 20 and is fixedly connected to the inner bottom wall of the delivery channel 19. The piston block 22 is fixedly connected to the top end of the telescopic rod 24. A spring 25 is sleeved on the telescopic rod 24. The two ends of the spring 25 are respectively fixedly connected to the bottom of the piston block 22 and the bottom of the delivery channel 19. The piston block 22 is located on one side of the delivery port 21 and opens and closes the delivery port 21. The gas is discharged from the airbag component and enters the upper channel 23 through the gas port. The gas in the upper channel 23 compresses the piston block 22 and the telescopic rod 24, sucking the liquid in the stock solution pipe into the delivery channel 19 and then entering the first spraying component to spray the rice, realizing the inoculation of pathogenic bacteria on the rice.

[0042] One side of the telescopic rod 24 is fixedly connected with a first fixing rod 28. A contact 27 is provided on the first fixing rod 28. One side of the inner side wall of the compression channel 20 close to the contact 27 is fixedly connected with a copper sheet 26. A DC power supply is also provided in the compression channel 20. The DC power supply is signal-connected to the controller. The copper sheet 26 is circuit-connected to the positive pole of the DC power supply, and the contact 27 is circuit-connected to the negative pole of the DC power supply. The contact 27 and the copper sheet 26 can contact and slide in cooperation. When the contact 27 contacts the copper sheet 26, the circuit loop is closed. The current flowing from the contact 27 through the copper sheet 26 by the DC power supply cannot reach the set threshold of the controller. Therefore, the controller determines that the piston block 22 has not been pressed to the lowest point. When the contact 27 touches the bottom of the copper sheet 26, the path of the DC power supply flowing from the contact 27 through the copper sheet 26 is the shortest, and the current reaches the set threshold of the controller. At this time, the controller determines that the piston block 22 has been pressed to the lowest point. When there is no contact between the contact 27 and the copper sheet 26, the loop is disconnected, and a limiting block 29 for restricting the position of the contact 27 is provided at the bottom of the copper sheet 26. By forming a closed loop with the DC power supply, the contact 27 and the copper sheet 26, a signal can be transmitted to the controller, and the second spraying assembly can be controlled by the controller to spray the rice leaves.

[0043] The clamping assembly includes a hollow second fixing rod 9 fixedly connected to one side of the lower part of the cultivation tank 6. One end of the second fixing rod 9 far from the cultivation tank 6 is fixedly connected with a fixed clamp 11. The fixed clamp 11 is signal-connected to the controller. The input end of the second fixing rod 9 is communicated with the conveying port 21, and the output end of the second fixing rod 9 is communicated with the first spraying assembly. The pipe diameter from the second conveying pipe 18 to the second fixing rod 9 gradually decreases. Based on the Venturi effect, the flow rate of the original pathogen solution from the second conveying pipe 18 to the second fixing rod 9 increases as the pipe diameter decreases. The first spraying assembly includes a first spray head 13 fixedly connected to the second fixing rod 9. The input end of the first spray head 13 is communicated with the output end of the second fixing rod 9. Thus, the original pathogen solution is sprayed out from the first spray head 13. The airbag assembly includes airbags 12 symmetrically arranged and fixedly connected to the inner side wall of the fixed clamp 11. Air pipes 10 are communicated with the airbags 12. The air pipes 10 are all communicated with the gas port, and the air pipes 10 are all fixedly connected to both sides of the second fixing rod 9.

[0044] The second spraying assembly includes a hollow third fixing rod 7 fixedly connected to one side of the top of the cultivation tank 6. The input end of the third fixing rod 7 is communicated with the liquid tank 16. A liquid pump 15 is provided on the third fixing rod 7. The liquid pump 15 is signal-connected to the controller. One end of the third fixing rod 7 far from the cultivation tank 6 is fixedly connected with a second spray head 8. The input end of the second spray head 8 is communicated with the output end of the third fixing rod 7.

[0045] The specific implementation process is as follows: Rice seedlings of different disease-resistant varieties are planted in different cultivation zones 2, or a control experiment is carried out. The cultivation components of each cultivation zone 2 act on a single rice seedling. A cultivation tank 6 is placed on one side of the rice seedling. Different types of pathogen stock solutions are filled into the stock solution tubes. The fixing clip 11 is used to clamp the rice roots to ensure that they do not shake or fall during the growth process.

[0046] When the rice grows to a certain stage, the controller activates the mixing pump 17 according to the preset pathogen stock solution that the rice seedling needs to be inoculated with. The mixing pump 17 pumps out one or more pathogen stock solutions and transports them to one side of the conveying channel 19 through the first conveying pipe. When the growth of the rice seedling does not reach the inoculation standard, the root diameter of the rice seedling is not large enough to squeeze the airbag 12 to discharge enough air into the upper channel 23 to squeeze the piston block 22. As the growth of the rice seedling gradually reaches the inoculation standard, the root diameter of the rice seedling gradually squeezes the airbag 12 to discharge the gas in the airbag 12 into the upper channel 23. The air in the conveying channel 19 accumulates and presses down the piston block 22. The piston block 22 moves down to below the liquid inlet. Since the conveying channel 19 is hourglass-shaped, when the pathogen stock solution accumulated in the second conveying pipe 18 is instantaneously released, because the pipe diameter from the second conveying pipe 18 to the second fixing rod 9 gradually decreases and there is a one-way valve in the upper channel 23, the pathogen stock solution cannot enter the upper channel 23 through the one-way valve. And there is a piston block 22 blocking in the compression channel 20. Based on the Venturi principle, the flow rate of the fluid will increase when it flows from a wide place to a narrow place. Therefore, the flow rate of the pathogen stock solution entering the inside of the second fixing rod 9 through the delivery port 21 gradually increases. As a result, when the pathogen stock solution flows out from the first nozzle 13, due to the excessive pressure, it sprays out from the first nozzle 13. During this process, due to the large accumulation of the pathogen stock solution in the first conveying pipe and the large air pressure, the energy released after energy storage can quickly spray from the first nozzle 13 to the roots of the rice seedling, resisting the resistance of the water at the roots, rather than slowly dissolving the pathogen stock solution in the water to contaminate other rice seedlings. And the fixing clip 11 also plays a role in preventing the splashing of the pathogen stock solution; when the pathogen stock solution in the first conveying pipe is spraying, the gas in the upper channel 23 rises under the extrusion of the pathogen stock solution. At the same time, the piston block 22 gradually resets under the elastic energy storage of the spring 25, making the piston block 22 block the liquid inlet again, and at the same time squeezing the gas in the upper channel 23 into the airbag 12 again. As a root spraying process, at the same time, the controller adjusts the angle of the fixing clip 11 to become larger to adapt to the root diameter of the rice seedling until the root diameter of the rice seedling squeezes the airbag 12 again.

[0047] Under the extrusion of the air in the conveying channel 19, the piston block 22 compresses the telescopic rod 24 to move downward, and the contact 27 on the first fixed rod 28 gradually contacts the copper sheet 26. During the spraying process of the first nozzle 13, the telescopic rod 24 is compressed to the critical value. At this time, the contact 27 is located at the bottom end of the copper sheet 26, enabling the DC power supply to form a closed circuit to send a current signal to the controller. The controller records this signal as a root spraying process. Since the roots of the rice seedlings can trigger root spraying multiple times during the growth process, but the leaf parts are not yet fully developed, it is not appropriate to inoculate pathogens at this time. Therefore, the controller will record the multiple root spraying processes according to the preset records, indirectly record the growth trend of the rice seedlings, and then start the liquid pump 15 after the number of root sprayings reaches the preset value, and implement pathogen inoculation by spraying the leaf parts of the rice seedlings through the second nozzle 8, ensuring the purpose of automatically inoculating pathogens according to the growth conditions of the rice seedlings.

[0048] Embodiment 2:

[0049] As shown in the attached Figure 1 figure, the difference from Embodiment 1 is that adjustment components are provided in each of the cultivation partitions 2. The adjustment components each include a temperature and humidity sensor fixedly connected to the partition board 4 and a third nozzle 3 fixedly connected to the top of the partition board 4. The input ends of the third nozzles 3 are all communicated with a water delivery pipe. One end of the water delivery pipe far away from the third nozzle 3 is communicated with a water tank 5. A water pump is provided on the water delivery pipe. A number of electric heating wires are provided in each of the partition boards 4. The temperature and humidity sensor, the water pump and the electric heating wires are all in signal connection with the controller.

[0050] The specific implementation process is as follows: During the cultivation process of the rice seedlings, the temperature and humidity in the cultivation partition 2 can be monitored in real time through the temperature and humidity sensor and fed back to the controller. Through the controller, the electric heating wires can accurately adjust the temperature in the cultivation partition 2, and the water pump can control the spraying amount of the third nozzle 3, thereby adjusting the humidity. This precise control makes the adjustment of environmental parameters more timely and accurate, and helps to improve the growth quality and disease resistance of the rice.

[0051] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
