By setting the retaining plate 14 at the bottom of the planting box 1, the planting box 1 is stably supported, ensuring that the planting box 1 is placed stably and reducing shaking or tilting caused by external forces or environmental factors. By movably mounting the water tank 15 inside the retaining plate 14, the irrigation water is collected and stored, effectively avoiding water waste and facilitating centralized management of irrigation water. The handle on the water tank 15 provides a convenient operating gripping point, making the installation, disassembly, and cleaning of the water tank 15 more convenient. By setting up an irrigation mechanism between the water tank 15 and the planting box 1, the irrigation process is made more automated and precise, and irrigation can be carried out according to the actual needs of the Gastrodia elata plants, improving the efficiency of water resource utilization and providing a more suitable growth environment for the Gastrodia elata plants.

[0026] The irrigation mechanism includes a water pump 17 installed inside the water tank 15, a drain pipe 16 installed at the discharge end of the water pump 17 and extending outside the water tank 15, an extension pipe 10 installed on the drain pipe 16 via a threaded connector 13, and a nozzle 11 installed on the extension pipe 10 for spraying irrigation water. The nozzle 11 is located above the planting box 1. By setting up the water pump 17 inside the water tank 15, the purpose of actively extracting irrigation water is achieved, ensuring the continuity and stability of the irrigation process. By connecting the discharge end of the water pump 17 to the drain pipe 16... Extending beyond the water tank 15, it serves to transport water from the water tank 15 to the top of the planting box 1, providing a necessary channel for irrigation. The extension pipe 10 is installed on the drain pipe 16 via the threaded connector 13, allowing the irrigation range to be flexibly adjusted according to actual needs, improving the flexibility and efficiency of irrigation. By installing the nozzle 11 on the extension pipe 10 and positioning the nozzle 11 above the planting box 1, the irrigation water can be evenly sprayed onto the Gastrodia elata plants, ensuring the uniformity and effectiveness of irrigation, which helps the healthy growth of the Gastrodia elata plants, while also saving water resources.

[0027] The top of the planting box 1 is fixed with a bracket 9 for supporting the extension pipe 10. The extension pipe 10 is provided with a flexible hose section 12 for assisting the extension pipe 10 in its extension, contraction, and bending. By setting the bracket 9 on the top of the planting box 1, the extension pipe 10 is stably supported, effectively preventing it from sagging or swaying due to its own weight or external force, thus ensuring the stability and reliability of the irrigation system. The flexible hose section 12 on the extension pipe 10 assists in its extension, contraction, and bending, allowing the extension pipe 10 to be flexibly adjusted according to actual irrigation needs. This allows users to adjust the irrigation position and angle according to different planting areas or the growth of the Gastrodia elata plants. The combination of the bracket 9 and the flexible hose section 12 ensures that the irrigation system is both stable and flexible.

[0028] The inlet end of the water pump 17 is fitted with a filter screen 18 for secondary filtration of irrigation water. The planting box 1 is equipped with a soil moisture sensor for monitoring soil temperature and humidity. By fitting the filter screen 18 to the inlet end of the water pump 17, the beneficial effect of secondary filtration of irrigation water is achieved. This effectively intercepts impurities and particulate matter that may be present in the water, preventing these impurities from entering the water pump 17 and subsequent irrigation system. This avoids blockage or damage caused by impurities, thereby extending the service life of the irrigation system and ensuring the cleanliness of the irrigation water, which is conducive to the healthy growth of Gastrodia elata. By setting a soil moisture sensor in the planting box 1, the soil temperature and humidity can be monitored in real time, allowing users to understand the soil environment in a timely manner and adjust the irrigation amount and frequency according to actual needs. This achieves precise irrigation, which not only saves water resources but also provides the most suitable growth environment for Gastrodia elata, helping to improve the yield and quality of Gastrodia elata.

[0029] The top of the support rod 6 is covered with a transparent film to isolate natural rainwater. Crossbars are installed on both sides of the transparent film to support it. These crossbars are placed on the connecting plate 5. By covering the top of the support rod 6 with a transparent film, natural rainwater is effectively isolated, preventing excessive moisture in the growing box 1 due to excessive rainwater. It also prevents untreated rainwater from directly irrigating and contaminating the substrate. The crossbars installed on both sides of the transparent film and placed on the connecting plate 5 provide stable support for the transparent film, ensuring that it covers the top of the support rod 6 smoothly.

[0030] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.

[0032] This solution also includes a controller, which is installed on the equipment. During use, the controller can be used to start the operation of each electrical device. The power connection method of each electrical device is an existing mature technology and is well known to those in the field. It will not be described in detail here. The water pump 17 can be any one of the IS series, the soil moisture sensor can be an FDR-100 soil moisture sensor, and the controller can be a CNC controller.

[0033] In use, first place the planting box 1 in a suitable environment for the growth of Gastrodia elata, ensuring that the bottom plate 14 is stably supported. Insert the water tank 15 into the plate 14 and connect the irrigation mechanism between the water tank 15 and the planting box 1. Lay a gauze sheet 3 on the support mesh plate 2 of the planting box 1, then place the culture medium on the gauze sheet 3, ensuring even distribution and preventing overflow. Fix the support plate 4 to the outer wall of the planting box 1. Place the connecting plate 5 and support rod 6 in sequence, and unfold the protective net 7 covering the support rod 6. Simultaneously unfold the isolation net 8 sewn onto the protective net 7 to ensure comprehensive coverage and effective isolation of pests and contaminants. Cover the top of the support rod 6 with a transparent film, using a crossbar to support the transparent film, ensuring the crossbar is stably placed on the connecting plate 5. To prevent excessive natural rainwater from entering the planting box 1 (the transparent film can be removed on sunny days), install the water pump 17 inside the water tank 15 and connect the inlet end (covered with the filter screen 18) and the outlet end (connected to the outlet pipe 16). At the same time, install the extension pipe 10 on the outlet pipe 16. Adjust the position of the nozzle 11 so that it is above the planting box 1. Install a soil moisture sensor inside the planting box 1 to monitor soil temperature and humidity in real time. When the soil moisture sensor detects that the soil humidity is lower than the set threshold, the controller starts the water pump 17. The water pump 17 draws irrigation water from the water tank 15, filters it twice through the filter screen 18, and then delivers it to the nozzle 11 through the outlet pipe 16 and the extension pipe 10. The nozzle 11 sprays the irrigation water evenly onto the Gastrodia elata plants.
