Greenhouse micro sprinkler nozzle diameter is small, pressure, there is a lot of fog index can improve air humidity, reduce small ambient temperature, regulate local climate, suitable for acting on the fungus and other hi damp fungus crops. In its construction should meet the requirements are: ① should collect basic information on water, weather, topography, soils, crops, irrigation experiment, energy and equipment, socioeconomic status and other aspects of development planning, feasibility study. ② irrigated plain areas hilly area of ??more than 100 hectares of irrigated area greater than 50 hectares of micro-irrigation projects should be divided into planning and design of the two phases, a small area can be combined into one phase. ③ should meet the requirements of the local agricultural zoning and irrigation planning and coordination with the rural development plan should include water projects, the first hub and the pipe network layout plan and proposed budget for the project. ④ greenhouse micro sprinkler irrigation methods should be adapted to local conditions. Not only that, there are certain greenhouse micro sprinkler water supply capacity, can increase soil moisture, refraction, rotation, or radiation micro sprinklers evenly sprayed water to irrigation methods such as crop foliage area.
