[0002] A greenhouse is a common agricultural facility. It changes the temperature inside the greenhouse through a frame covering structure, thereby achieving the effect of off-season vegetable planting and seedling cultivation. When the greenhouse is in use, there is no natural rainwater for irrigation. In order to ensure sufficient water irrigation, a spray irrigation device is generally installed in the greenhouse to meet the water requirements for crop growth. However, the existing water and fertilizer spray irrigation device for seedling greenhouses still has some disadvantages, such as its high cost and high subsequent maintenance cost. It is impossible to adjust the position according to the use requirements during use, and it is very cumbersome to install and disassemble. Moreover, since it is set at the top of the greenhouse, when it fails, personnel cannot quickly perform maintenance and replacement.
