With global climate change and population growth, the contradiction between water supply and demand has become increasingly prominent, especially in the field of agricultural irrigation. When irrigating vegetables, traditional irrigation methods usually use kettles for spraying. Due to the large area of ​​the greenhouse, a large amount of manpower is required to water the plants piece by piece. This method is not only time-consuming, but also requires multiple people to help with watering. There are often problems such as serious waste of water resources and low utilization efficiency. Tidal irrigation has effectively improved the work efficiency of modern agriculture and is the future direction of agricultural development. However, the existing tidal irrigation equipment has a complex structure and high price. It is not suitable for small-scale planting irrigation, especially for irrigation of seedling beds, which is not conducive to the promotion of tidal irrigation. Utility Model Content

After the crop roots fully absorb the nutrient solution, the liquid level will continue to rise. When the liquid level reaches the height position of the upper end of the semicircular tube 5, due to the siphon principle, when one end of the pipe is lower than the liquid level, sufficient negative pressure can be generated to make the liquid overcome gravity and flow, and the outlet pipe 2 begins to drain outward, thereby achieving the effect of tidal irrigation. The device is also provided with a lifting and adjusting device 11, so that the height of the outlet pipe 2 is adjustable, thereby achieving a control effect on the liquid level inside the seedbed 1.

[0022] In summary, the utility model can save labor costs, realize effective irrigation of the seedbed, and has the advantages of simple structure and easy installation.
