Due to its good economic benefits, the planting area of greenhouse vegetables is getting larger and larger, especially the use of advanced water-saving irrigation technology (drip irrigation, micro-spray irrigation), which can achieve significant water-saving, labor-saving, production increase, and crop quality improvement effects , More and more greenhouses are beginning to use techniques such as drip irrigation and micro-sprinkler irrigation for irrigation. Different from the traditional flood irrigation method, the implementation of water-saving irrigation technology requires a certain number of water transmission and distribution pipes near the greenhouse. When the crops need to be irrigated, the valve can be opened to irrigate. However, the application of this water-saving irrigation technology in greenhouses currently has the following problems: the weather is hot in summer, and the irrigation system pipes are exposed to the sun, and the water temperature in the pipes is bound to increase. If water is poured into the roots of soil crops, it will cause crops harm. In winter, the indoor temperature is low, which is not conducive to crop growth. The irrigation water source is also piped from the outside of the greenhouse, and the water temperature is also low. Under this condition, irrigation will further reduce the soil temperature, which is not conducive to crop growth.
