[0038] A guide plate 3 is provided on the outside of each insulation plate 15. The design of the guide plate 3 is conducive to collecting and guiding the excess moisture generated by natural precipitation or the large temperature difference between day and night on the surface of the device, thereby improving the utilization of resources;

[0039] The outer surface of the lower end of the insulation plate 15 is fixedly connected to the surface of the guide plate 3, wherein the outer sides of the two symmetrical guide plates 3 are provided with energy supply mechanisms 4, and the setting of the energy supply mechanisms 4 is adjusted according to the position of the sun and the angle of illumination to maximize the reception of solar energy and improve the efficiency of energy acquisition;

The above-mentioned arrangement cooperates with the temperature sensor fixed on the inner side of the insulation board 15 to monitor the ambient temperature of the seeds in real time. When the ambient temperature is low, the fan 10 heats the carbon fiber heating tube 9 and then accelerates the circulation of hot air, so that the heat is evenly distributed inside the device, creating a suitable germination temperature environment for the seeds.

[0043] In this embodiment, the positioning mechanism 2 includes a gear 21 symmetrically arranged along the central axis of the limit frame 11, a spiral nail 22 is fixedly connected to the lower end of the gear 21, and the upper end of the gear 21 is rotatably connected to the inner wall of the sliding groove 16 through a bearing.

[0044] Specifically, the spiral nail 22 fixed at the lower end of the gear 21 can be rotated to screw the spiral nail 22 deeply into the sand layer when the device is placed on the sand. Compared with the ordinary flat-bottomed support structure, the spiral nail 22 can provide greater grip, effectively resist the lateral pushing force of wind and sand on the device, and ensure that the device stands firmly in the soft and windy desert sand, creating a stable and undisturbed basic environment for seed germination; the entire positioning mechanism 2 is driven to operate by rotating the rotating rivet 24 with an electric screwdriver. Compared with multiple decentralized operation points, the installation and debugging process of the device is greatly simplified, especially in the wild desert environment. The convenient operation can save a lot of time and energy for the staff.

[0045] In this embodiment, the energy supply mechanism 4 includes a solar panel 41, and a rotating column 42 is fixedly connected to one side of the solar panel 41. The outer surface of the rotating column 42 is fixedly arrayed with two bearings, and the outer ring of each bearing is fixedly connected to the outer surface of the guide plate 3. The two ends of the rotating column 42 are respectively rotatably hinged with a limit rod 43, and the two ends of the rotating column 42 are respectively fixedly connected with a blocking rod 44, and the surface of the blocking rod 44 is fitted with the surface of the limit rod 43. The outer surface of the guide plate 3 is fixedly connected with a fixing plate 45, and a ratchet groove 46 adapted to the surface of the limit rod 43 is opened on one side of the fixing plate 45. The surface of the limit rod 43 is ratcheted and connected with the inner wall of the ratchet groove 46.

[0046] Specifically, the solar panel 41 is flexibly rotated with the rotating column 42 connected to one side and the outer surface of the guide plate 3 through the bearing 2. The operator can pre-rotate the two smaller solar panels 41 when the solar altitude angle is low in the morning or evening, so that the surface of the solar panel 41 is as perpendicular to the incident direction of sunlight as possible to receive sunlight to the greatest extent; and then, when the solar altitude angle is high at noon, the operator can pre-adjust the angle of the two larger solar panels 41 to ensure that the sunlight irradiates the panel surface at a nearly vertical angle, effectively improving the solar energy collection efficiency, providing sufficient guarantee for the continuous power supply of the device, and meeting the energy demand during the seed germination process.

[0047] In this embodiment, the water supply mechanism 7 includes a water storage barrel 71 arranged on the outside of the four corners of the limiting frame 11, a small water supply pump 72 is arranged on the upper surface of the water storage barrel 71, and a connecting pipe 73 is arranged on the body of the water storage barrel 71. The inner wall of one end of the connecting pipe 73 is fixedly connected to the inner wall of the water storage barrel 71, and the water outlet end of the small water supply pump 72 is connected to the water inlet pipe 74 through a flange. One end of the connecting pipe 73 passes through the body of the insulation board 15 and extends to the inner side of the insulation board 15. The inner side surface of the insulation board 15 is provided with a main pipeline 75. The inner wall of the water inlet pipe 74 is fixedly connected to the inner wall of the main pipeline 75. The main pipeline 7 5 is provided with water outlet holes, both ends of the main pipeline 75 are respectively connected to water supply pumps, the main pipeline 75 is fixedly connected to the pipe body of the main pipeline 75 with an auxiliary pipe 76, the inner wall of the auxiliary pipe 76 is fixedly communicated with the inner wall of the main pipeline 75, one end of the auxiliary pipe 76 penetrates the body of the limiting frame 11 and extends to its lower surface, and half of the remaining part of the auxiliary pipe 76 is embedded in the body of the limiting frame 11 at the lower end, and the upper surface of the limiting frame 11 is dispersedly provided with nozzles 77, and the inner wall of the lower end of the nozzle 77 is fixedly communicated with the inner wall of the auxiliary pipe 76 through a delivery pipe, and the delivery pipe is embedded in the body of the limiting frame 11.

[0048] Specifically, the water outlet holes arrayed on the main pipe 75 and the auxiliary pipe 76 connected to the main pipe work together to achieve uniform distribution of water on the upper surface of the limiting frame 11. The auxiliary pipe 76 extends to the lower surface of the limiting frame 11 and is partially embedded, and then connected to the nozzles 77 dispersed on the upper surface of the limiting frame 11 through the delivery pipe, so that water can be evenly sprayed to the area where the seeds are located, avoiding local drought or water accumulation, creating a consistent moisture environment for seed germination, and is conducive to improving the germination rate of seeds and the uniformity of seedling growth; the water storage barrel 71 is set outside the four corners of the limiting frame 11, which is convenient for centralized storage Water storage resources. In the case of scarce water resources in desert areas, this design can effectively collect and store limited water sources. The rainwater collected by the guide plate 3 or the water condensed on the outer surface of the insulation plate 15 due to the temperature difference between day and night can provide continuous water supply for seed germination; the auxiliary pipe 76 is partially embedded in the body of the lower end of the limit frame 11, and the delivery pipe is embedded in the body of the limit frame 11, which reduces the contact between the pipeline and the external environment, reduces the erosion and aging effects of harsh conditions such as wind, sand, and high temperature on the pipeline, extends the service life of the pipeline, and reduces maintenance costs and the risk of water supply failures due to pipeline damage.

[0049] In this embodiment, the interior of the guide plate 3 is a symmetrical inclined arc surface, and guide holes are respectively opened at both ends of the guide plate 3. The inner wall of each guide hole is fixedly connected to the outer surface of the connecting pipe 73.

[0050] Specifically, the symmetrical inclined arc surface inside the guide plate 3 can accurately capture rainwater falling from the sky or water droplets condensed on the outer surface of the insulation plate 15 due to the large temperature difference between day and night in the desert, and finally gather in the guide plate 3. Its special inclined arc surface can guide the rainwater to flow to both ends. When the water droplets contact the inclined arc surface of the guide plate 3, the rainwater will converge to both ends along the slope, and finally flow into the water storage barrel 71 through the guide hole and the connecting pipe 73. This efficient rainwater collection mechanism maximizes the use of natural precipitation, replenishes precious water resources for seed germination in the device, reduces dependence on external water supply, and improves the self-sufficiency of the device in the desert environment.

[0051] In this embodiment, the insulation board 15 is a double-layer hollow structure, the inner layer of the insulation board 15 is a degradable PLA film, the outer layer of the insulation board 15 is made of aluminum alloy, and the interlayer of the insulation board 15 is filled with a paraffin base uniformly mixed with 20% nano-scale silica particles.

[0052] Specifically, the paraffin base filled in the double-layer hollow interlayer is a phase change material, which has the characteristics of absorbing or releasing a large amount of latent heat at a specific temperature. When the ambient temperature rises, the paraffin base absorbs heat and undergoes a phase change, changing from solid to liquid, thereby storing heat; when the ambient temperature drops, the paraffin base will release the stored heat and change from liquid back to solid. This phase change process can effectively buffer temperature changes, further enhance the insulation effect of the insulation board 15, and reduce the impact of external temperature fluctuations on seed germination; while nano-scale silicon dioxide has a high specific surface area and a porous structure, which can increase thermal resistance and reduce thermal conductivity. At the same time, it can also prevent the flow and leakage of the paraffin base during the phase change process, thereby improving the stability and service life of the phase change material; in the desertification control scenario, the use of degradable PLA film helps to reduce the negative impact on the ecological environment, which is in line with the concept of sustainable development. When the device completes its mission or is abandoned, the degradable PLA film will decompose naturally, leaving no difficult-to-handle waste, and. Aluminum alloy can be recycled and reprocessed.

[0053] In this embodiment, an air humidity sensor and a light sensor are provided on the upper surface of the limit frame 11, and a soil humidity sensor is provided at the contact position between the limit frame 11 and the desert sand. The above-mentioned sensors are connected to the control signal fixed on the outer side of the guide plate 3 through cables.

[0054] Specifically, the air humidity sensor continuously collects humidity data and transmits it to the controller connected thereto, so that the operator can timely understand the dynamic changes of the air humidity in the device; according to the light intensity information fed back by the light sensor, the light adjustment component 5 can automatically adjust the light transmittance. When the light is too strong, the light adjustment component 5 will reduce the light transmittance and reduce the amount of light entering the device to avoid seeds being burned by strong light; when the light is insufficient, the light adjustment component 5 will increase the light transmittance and increase the light intensity to meet the needs of seed photosynthesis and ensure that the seeds can obtain suitable light under different light conditions. Suitable light promotes its normal growth and development; the controller accurately controls the operation of the water supply mechanism 7 according to the data fed back by the soil moisture sensor. When the soil moisture is lower than the set suitable range, the controller will start the water supply pump connected to the main pipeline 75 to start supplying water, and replenish water to the soil through the water outlet of the main pipeline 75 and the nozzle 77 to ensure that the soil maintains sufficient humidity; when the soil moisture reaches the suitable range, the water supply pump automatically stops working to avoid problems such as soil waterlogging caused by excessive irrigation and seed rotting due to lack of oxygen, thereby achieving accurate regulation of soil moisture and providing good soil conditions for seed germination.

[0055] Reference Figure 1-Figure 13 , a construction method of a device for promoting seed germination by desertification, the operation steps are as follows:

[0056] Step 1: Place the seed germination device on the desert sand, and use an electric screwdriver to dock the rotating rivet 24 in the slot, the electric screwdriver drives the rotating rivet 24 to rotate, the rotating rivet 24 drives the chain 23 meshing with the gear 21 to rotate, and multiple spiral nails 22 rotate at the same time, deep into the sand, until the lower end of the limit frame 11 is embedded in the sand, stop the electric screwdriver and move it away;

[0057] Step 2: Place the seed capsule in the sand in each grid formed by the limit frame 11, then insert the root guide tube 14 into the sand and keep the horizontal distance from the seed capsule at 5-10 cm, then fix the light adjustment component 5 on the upper end of the insulation board 15, and the light sensor feeds back the collected light information to the controller, and the controller controls the light adjustment component 5 to adjust the light transmittance. At the same time, the workers manually rotate the two shorter solar panels 41 so that the panel surface is as vertical as possible to the sunlight in the morning or evening, and adjust the two longer solar panels 41 again so that the panel surface is as vertical as possible to the sunlight at noon, and the light collected by the solar panels 41 is converted into electrical energy and stored in the battery 8;

[0058] Step 3, when the information collected by the soil moisture sensor and the air humidity sensor is fed back to the controller, if the humidity value is within the preset range, the two sensors continue to monitor in real time, otherwise the controller controls the water supply pump connected to the main pipeline 75 to open, the main pipeline 75 starts to take in water, the water flows out through the water outlet of the main pipeline 75, and the water flows into the auxiliary pipe 76, and is sprayed out through the nozzle 77 fixedly connected to the auxiliary pipe 76. The values ​​fed back by the soil moisture sensor and the air humidity sensor are all within the preset range, and the controller controls the water supply pump to stop working. If there is a problem with the water supply pump and the main pipeline 75 cannot supply water normally, the controller activates the reserve plan and starts the small water supply pump 72. The small water supply pumps 72 located at the four corners of the limit frame 11 simultaneously transport the water source in the water storage barrel 71 to the main pipeline 75 through the water inlet pipe 74, so that it can complete the water supply function normally.

[0059] Step 4: The temperature sensor fixed on the inner side of the insulation board 15 monitors the seed environment temperature in the device in real time. If the temperature drops, the information is fed back to the controller. The controller controls the carbon fiber heating tube 9 to heat, and the fan 10 is turned on at the same time. The rotation of the fan 10 drives the air heated by the carbon fiber heating tube 9 to accelerate into the seed germination device, and the air in the device can flow.
