大棚滴灌具有降低湿度、提高地温、节水、省工和高效、增产等许多优点。但大棚滴灌机械在使用中常出现灌水器损坏、滴孔堵塞、出水均匀度差及流量小等毛病。为了避免以上毛病的发生,用户应注意以下几点。1选择合适的滴灌机械①通过计算或按设计要求,选择合适的水泵;通过计算设计出合理的供水管径和管长,以达到较高的均匀度;供水管道应选择具有抗老化性能的塑料管材。②灌水器是关键部件,要选择出水均 Drip shed with a greenhouse to reduce humidity, improve ground temperature, water, labor and efficient, yield and many other advantages. However, greenhouses drip irrigation machinery used in the often appear emitter damage, drip hole plugging, poor water uniformity and flow problems. In order to avoid the above problems, users should pay attention to the following points. 1 choose the appropriate drip irrigation machinery ① by calculating or according to design requirements, select the appropriate pump; calculated through the design of a reasonable supply pipe diameter and pipe length, in order to achieve a high degree of uniformity; water supply pipe should be selected with anti-aging properties of plastic Pipe. ② emitter is a key component, to select the water are
