[0021] In actual use, soil is laid in the culture cabin 2, and the pear seedlings are cultivated in the soil in the culture cabin 2. When the pear seedlings need to be watered, the top cover 6 is first removed from the water inlet 5, and then the nutrient solution is poured into the water tank 1 from the water inlet 5. After pouring, the top cover 6 is put back into the water inlet 5 to prevent dust, flying insects, etc. from entering the water tank 1, thereby blocking the leakage port 9 opened on the surface of the water tank bottom 8, and then the pull rod 18 in the pull rod hole 17 is pulled outward. The movement of the pull rod 18 causes the movable plate 11 to move in the same direction until the end of the movable plate 11 fixed with the pull rod 18 is against the inner side of the interlayer 10. On the wall, on the one hand, the spring 16 is compressed and completely retracted into the spring groove 15, and on the other hand, the through hole 12 is aligned with the leakage port 9, so that the nutrient solution in the water tank 1 is sprinkled into the culture chamber 2 through a plurality of groups of evenly distributed leakage ports 9 and through holes 12, and the soil in the culture chamber 2 where the pear seedlings are cultivated is evenly watered. After the watering is completed, the pull rod 18 is released, and the spring 16 pushes the movable plate 11 back to its original position, so that the positions of each group of through holes 12 and each group of leakage ports 9 are staggered, thereby ensuring that the nutrient solution can be accumulated in the water tank 1 first when the nutrient solution is poured into the water tank 1 next time.

[0022] Embodiment 2

[0023] On the basis of Example 1, in order to prevent the nutrient solution from leaking from the gap between the inner wall of the interlayer 10 and the movable plate 11, a plurality of groups of sealing sheet grooves 13 are provided on the surface of the movable plate 11. The sealing sheet grooves 13 are in an annular groove structure. The positions of the plurality of groups of sealing sheet grooves 13 on the surface of the movable plate 11 correspond one-to-one to the plurality of groups of through holes 12. A sealing sheet 14 is provided in the sealing sheet groove 13, and the top end of the sealing sheet 14 is against the inner wall of the interlayer 10.

[0024] An annular sealing sheet groove 13 is provided next to each group of through holes 12, and a sealing sheet 14 is provided in the sealing sheet groove 13. The sealing sheet 14 is made of a highly elastic material, and the top of the sealing sheet 14 is against the inner wall of the interlayer 10, so as to fill the gap between the inner wall of the interlayer 10 and the movable plate 11, thereby preventing the nutrient solution from leaking from the gap between the inner wall of the interlayer 10 and the movable plate 11.

[0025] Embodiment 3

[0026] On the basis of the second embodiment, in order to facilitate the observation of the pear seedlings in the culture chamber 2, an observation window 4 is provided on the surface of the culture chamber 2.

[0029] When too much nutrient solution is applied to the soil in the culture chamber 2 where the pear seedlings are cultivated, the excess nutrient solution will precipitate from the soil and, under the action of gravity, seep into the residual liquid collecting chamber 3 through the residual liquid through hole 19. The nutrient solution in the residual liquid collecting chamber 3 can be taken out with a bucket by opening the drain pipe 7. After processing and removing the mixed soil, the nutrient solution can be kept for next use.

[0030] In actual use, soil is laid in the culture cabin 2, and the pear seedlings are cultivated in the soil in the culture cabin 2. When the pear seedlings need to be watered, the top cover 6 is first removed from the water inlet 5, and then the nutrient solution is poured into the water tank 1 from the water inlet 5. After pouring, the top cover 6 is put back into the water inlet 5 to prevent dust, flies, etc. from entering the water tank 1, and the leakage port 9 opened on the surface of the water tank bottom 8 is blocked, and then the pull rod 18 in the pull rod hole 17 is pulled outward, and the movement of the pull rod 18 causes the movable plate 11 to move in the same direction , until one end of the movable plate 11 fixed with the pull rod 18 is against the inner wall of the interlayer 10, which on the one hand compresses the spring 16 and completely retracts into the spring groove 15, and on the other hand aligns the through hole 12 with the leakage port 9, so that the nutrient solution in the water tank 1 is sprinkled into the culture cabin 2 through a plurality of groups of evenly distributed leakage ports 9 and through holes 12, and the soil in the culture cabin 2 where the pear seedlings are cultivated is evenly irrigated. After the irrigation is completed, the pull rod 18 is released, and the spring 16 pushes the movable plate 11 back to its original position, so that The positions of each group of through holes 12 and each group of leakage ports 9 are staggered, so as to ensure that the nutrient solution can be first accumulated in the water tank 1 when the nutrient solution is poured into the water tank 1 next time; an annular sealing sheet groove 13 is provided next to each group of through holes 12, and a sealing sheet 14 is provided in the sealing sheet groove 13. The sealing sheet 14 is made of a highly elastic material, and the top of the sealing sheet 14 is against the inner wall of the interlayer 10, so as to fill the gap between the inner wall of the interlayer 10 and the movable plate 11, thereby preventing the nutrient solution from flowing out from the inner wall of the interlayer 10 and the movable plate 11. Leakage occurs at the gap of the movable plate 11; in order to facilitate observation of the pear seedlings in the culture cabin 2, an observation window 4 is provided on the surface of the culture cabin 2; when too much nutrient solution is applied to the soil in which the pear seedlings are cultivated in the culture cabin 2, the excess nutrient solution precipitates from the soil and, under the action of gravity, seeps into the residual liquid collecting cabin 3 through the residual liquid through hole 19. The nutrient solution in the residual liquid collecting cabin 3 can be taken out with a bucket by opening the drain pipe 7, and can be kept for next use after the mixed soil is removed through processing.
