[0026] As Figures 1 to 5 shown, wedge blocks 10 are fixedly connected to the two sides of the adjusting plate 9, wedge grooves 11 are formed in the inner surfaces of the two sides of the water storage shell 1, and the outer surfaces of the wedge blocks 10 are movably embedded inside the wedge grooves 11. The adjusting plate 9 and the wedge blocks 10 move along the slotting direction of the wedge grooves 11.

[0027] As Figures 1 to 5 shown, a mounting sleeve 12 is fixedly connected to one side of the water storage shell 1, a motor 13 is fixedly embedded in the inner surface of the mounting sleeve 12, the output end of the motor 13 is fixedly connected to the end of the forward and reverse screw rod 2 extending out, and the motor 13 is fixed to one side of the water storage shell 1 through the mounting sleeve 12.

[0028] As Figures 1 to 5As shown, the bottom of the water storage shell 1 is fixedly connected with a pressure plate 14, and the top of the pressure plate 14 is fixedly connected with a main body 15 for planting, which is used for planting experimental objects.

[0029] As shown in the drawings, Figures 1 to 5 As shown, the pressure plate 14 is provided with a water outlet 16, and the bottom of the main body 15 for planting is provided with a plurality of water outlets 17, which are in communication with the water outlet 16. The excess water will flow out through the water outlets 17 and the water outlet 16 of the pressure plate 14.

[0030] As shown in the drawings, Figures 1 to 5 As shown, the inner surface of the water storage shell 1 is fixedly embedded with a water distribution shell 18, and the inner surface of the water distribution shell 18 is in communication with a plurality of water outlet pipes 19, which can be embedded in different depths of soil respectively. Because the lengths of the water outlet pipes 19 are different, the roots at different depths can obtain water in time.

[0031] As shown in the drawings, Figures 1 to 5 As shown, the top of the water distribution shell 18 is in communication with a hose 20, and the end of the hose 20 away from the water distribution shell 18 is in communication with a water pump 21.

The rotating thread will drive the internal threaded block 3, and the limiting plate 4 at the bottom of the internal threaded block 3 can only move along the slotting direction of the limiting groove 5, so the rotating thread will drive the two internal threaded blocks 3 to move closer to or away from each other. When the internal threaded block 3 moves, it will drive one end of the connecting rod 7 through the first shaft block 6, and the other end of the connecting rod 7 will push the adjusting plate 9 through the second shaft block 8, so that the adjusting plate 9 and the wedge block 10 move along the slotting direction of the wedge groove 11. In this way, the depth of the water suction pipe 22 embedded in the water in the water storage shell 1 is adjusted, and then the external power supply of the water pump 21 is started. After the water pump 21 is powered on, it will suck water into the water pump 21 through the water suction pipe 22, and then the water will flow into the water distribution shell 18 through the hose 20 after being pressurized by the water pump 21. Finally, the water flows into the main body 15 for planting through the water outlet pipes 19. Because the lengths of the water outlet pipes 19 are different, the roots at different depths can obtain water in time, which can avoid the roots from growing to a certain depth due to uneven water supply, promote the balanced growth of the roots, and the excess water will flow out through the water outlets 17 and the water outlet 16 of the pressure plate 14.
