[0068] Working principle: During the cultivation process, spray irrigation is required. During the spray irrigation, the second water pump 511 is controlled by the mobile terminal to work. When the second water pump 511 is working, the liquid in the second box 501 can be pumped out and discharged to the nozzle 305. The water sprayed from the nozzle 305 can realize the irrigation of the seedlings on the placement rack 1. When the irrigation range needs to be adjusted, the two second electric cylinders 301 can be controlled to extend and retract to achieve it; while spraying irrigation, the substrate in the cultivation pot on the placement rack 1 will be washed out or seeped out with the water under the impact of the water body, and the substrate will be washed out. The matrix after filtering will fall onto the blocking plate 202 and then flow to the right and gather. At this time, the V-shaped groove formed at the blocking plate 202 can block the matrix, ensuring the cleanliness of the water body after collection; in the process of collecting the water body, the liquid filtered by the filter assembly 2 will flow to the collecting pipe 102, and will be discharged to the first hose 404, the second hose 405 and the iron pipe 406 through the collecting pipe 102, and finally discharged into the first box 401 through the iron pipe 406, realizing the recovery of the water body and the fertilizer dissolved in the water body, saving water resources and improving the utilization rate of fertilizers;

[0069] The first water pump 503 is controlled to work by the mobile terminal. When the first water pump 503 is working, the settled water in the first box 401 can be pumped out and discharged into the second box 501. At this time, disinfectant can be added into the second box 501 through the funnel 510 to achieve the disinfection of the liquid in the second box 501. The concentration of the nutrient elements can also be tested by sampling at the funnel 510, and the concentration can be adjusted according to the concentration. After the adjustment is completed, the second water pump 511 can continue to be controlled to work to achieve spray irrigation;

[0070] When absorbing the water in the first box 401, the height of the absorption tube 505 can be adjusted to avoid absorbing the settled mud. During the adjustment, the height of the absorption tube 505 can be adjusted by controlling the rotation of the second motor 506 through the mobile terminal, thereby avoiding the absorption tube 505 from contacting the settled mud and sand, ensuring the cleanliness of the water in the second box 501, and avoiding the subsequent nozzle 305 from being blocked;

[0071] When it is necessary to clear the blockage of the through hole at the collecting pipe 102, the second motor 506 is controlled to rotate, and the sliding frame 504 moves upward under the drive of the second motor 506. When the sliding frame 504 moves upward until the rubber block elastically contacts the discharge end of the iron pipe 406, the iron pipe 406 is in a sealed state, and the second motor 506 is continuously controlled to rotate. At this time, the sliding frame 504 continues to move upward, and the second hose 405 can be deformed by squeezing the sliding frame 504 and the handle 407. At this time, the airflow refluxes, and the refluxed airflow can clear the blockage of the collecting pipe 102.

[0072] During use, the temperature data transmitted by the temperature sensor 509 on the mobile terminal can be observed. When the temperature is too low, the external heating device needs to be started;

[0073] When cleaning the mud and sand on the blocking plate 202 and the first elastic block 203, water can be used for flushing. During the flushing process, the first electric cylinder 208 can be controlled to retract through the mobile terminal. When the first electric cylinder 208 retracts, it can drive the gear row 206 to move forward. When the gear row 206 moves forward, it can drive the gear 204 and the blocking plate 202 to rotate. After the blocking plate 202 rotates and unfolds, the cleaning is more thorough.

[0074] The above are only specific implementations of the present disclosure, but the protection scope of the present disclosure is not limited thereto, and the protection scope of the present disclosure shall be based on the protection scope of the claims.
