[0025] The effect achieved by the entire embodiment 1 is as follows: First, the seedlings to be cultivated are placed inside the cultivation box 4. Then, the cultivation box 4 is placed in the storage tank 2. Then, water is injected into the hydroponic board 1. The water flow will be between the slow flow tank 12, the storage tank 2 and the outlet tank 14. When the water flow is at the normal liquid level, it will lift the float 11 upward, thereby driving the cylindrical tube 18 to slide upward. This causes the filter port 19 on the cylindrical tube 18 to be misaligned with the filter port 19 on the guide sleeve 17, thereby cutting off the cylindrical tube 18 and preventing the water flow inside the water tank 6 from being discharged into the slow flow tank 12.

[0026] Example 2, as Figure 1-4As shown, the filter port 19 on the outer surface of the guide sleeve 17 is located at the bottom edge of the guide sleeve 17, and the filter port 19 on the outer surface of the cylindrical tube 18 is located at the top edge of the cylindrical tube 18. The filter port 19 near the top of the cylindrical tube 18 is above the filter port 19 near the bottom of the guide sleeve 17. A slow-flow groove 12 is provided on the top of the hydroponic plate 1 near the water tank 6. A side opening 13 is provided on one side of the cylindrical hole 16, penetrating into the slow-flow groove 12. A connecting rod 15 is slidably arranged inside the side opening 13. One end of the connecting rod 15 is fixed to the outer surface of the cylindrical tube 18 near the bottom edge. A float plate 11 is slidably arranged between the inner walls of the slow-flow groove 12. The other end of the connecting rod 15 is fixed to the float plate 11. The top of the hydroponic plate 1... Multiple storage slots 2 are evenly spaced in the hydroponic board 1. Through openings 3 are provided on the inner walls of both sides near the bottom edge of the storage slots 2. A water outlet 14 is provided on the top of the hydroponic board 1 near the other side edge. The through openings 3 and the water outlet 14 are interconnected. The through openings 3 and the slow flow channel 12 are interconnected. A guide plate 8 is fixed on the front side of the hydroponic board 1 near the other side edge. One end of the guide plate 8 is connected to the inside of the water outlet 14. A pull-out groove 10 is provided on the top of the hydroponic board 1, which extends into the inside of the guide plate 8. A sealing plate 9 is provided inside the pull-out groove 10. A culture box 4 is provided inside the storage slots 2. Two cotton strips 5 are provided at the bottom of the culture box 4. The tops of the two cotton strips 5 extend into the inside of the culture box 4.

[0027] The effect achieved by the entire embodiment 2 is that when the water level on the hydroponic board 1 drops, it will drive the float 11 to drop as well. The drop of the float 11 will drive the cylindrical tube 18 to drop through the connecting rod 15. During the drop of the cylindrical tube 18, when the filter port 19 on the cylindrical tube 18 is aligned with the filter port 19 on the guide sleeve 17, the water inside the water storage tank 6 can be discharged into the slow flow tank 12. This cycle can be repeated to achieve the purpose of automatic water supply and can keep the water level on the hydroponic board 1 at a certain height.

[0028] Working principle: First, the seedlings to be cultivated are placed inside the cultivation box 4. Then, the cultivation box 4 is placed in the storage tank 2. Water is then injected into the hydroponic plate 1. The water flow will be between the slow-flow tank 12, the storage tank 2, and the outlet tank 14. When the water flow reaches the normal liquid level, it will lift the float 11 upward, thereby driving the cylindrical tube 18 to slide upward. This causes the filter port 19 on the cylindrical tube 18 to be misaligned with the filter port 19 on the guide sleeve 17, thus cutting off the cylindrical tube 18 and preventing water from flowing into the water tank 6. The water is discharged into the slow-flow trough 12. When the water level on the hydroponic board 1 drops, it will drive the float 11 to drop as well. The drop of the float 11 will drive the cylindrical tube 18 to drop through the connecting rod 15. During the drop of the cylindrical tube 18, when the filter port 19 on the cylindrical tube 18 is aligned with the filter port 19 on the guide sleeve 17, the water inside the water storage tank 6 can be discharged into the slow-flow trough 12. This cycle can be repeated to achieve the purpose of automatic water supply and keep the water level on the hydroponic board 1 at a certain height.
