When several plants with different water requirements are planted close together, precise irrigation of different plants is required.

[0004] Point irrigation is often used to irrigate the water spray position according to the water requirement of the plants. The existing irrigation methods include sprinkling irrigation and drip irrigation. In the sprinkling irrigation method, fixed nozzles or mobile nozzles are generally used. Although different ranges and angles of water flow can be sprayed, the adjustment method is too simple for point irrigation, and there are still some deficiencies in actual application, especially in environments with strong winds. The water flow is easily blown away by the wind, affecting the irrigation effect. When point irrigation is performed, the point irrigation position is easily shifted or the irrigation water flow is dispersed. At the same time, the existing equipment lacks effective adjustment of the water flow stability and spray direction, especially in high wind environments. The spray flow and water flow direction are easily affected by the external environment, resulting in low irrigation efficiency. The spray range and position of the water flow cannot be precisely controlled. How to irrigate multiple points after fixing, while considering wind resistance and flexible adjustment, is a problem that needs to be solved. SUMMARY
