微喷灌是利用管道输水由低压微喷头将水均匀地喷洒在作物根区土壤上的新型灌溉技术。由水源、首部枢纽、管网系统和微喷头四部分组成。其特点为: 省水:微喷灌采用管道输水,减少了沿程渗漏和蒸发损失,仅在作物根部均匀喷洒,灌水量小,不易发生地表径流和深层渗透,与其它灌水方法相比较,水的利用率高。 节能:微喷头工作压力低,需水少,降低了抽水扬程和抽水量,从而减少抽水能耗,比喷灌节能。 增产:微喷灌能适时适量地向作物根区供水,使 Micro-sprinkler irrigation is the use of pipelines from the low-pressure micro-nozzle water evenly spread in the crop root zone of the soil on the new irrigation technology. By the water, the first hub, pipe network system and micro-nozzle four parts. Its characteristics are: Water saving: Micro-sprinkler irrigation using pipelines to reduce leakage and evaporation along the process of loss, only the crop roots evenly sprayed with small amount of irrigation, less prone to surface runoff and deep infiltration, compared with other irrigation methods, High utilization of water. Energy-saving: Micro-nozzle working pressure is low, less water needs, reducing the pumping lift and pumping capacity, thereby reducing pump energy consumption than sprinkler energy saving. Yield: Micro-sprinkler timely and appropriate supply of water to the crop root zone
