喷灌是利用专门的设备（动力机、水泵、管道等）把水加压,或利用水的自然落差将压力水送到需要灌溉的地块,再通过喷洒器（喷头）喷射到空中分裂成细小的水滴,均匀落在田间进行灌溉。据分析,对一般土质,与传统地面灌溉方式相比,采用喷灌技术,粮食一般可增产１０%～２０%,经济作 Sprinkler irrigation is the use of specialized equipment (power machines, pumps, pipes, etc.) to pressurize the water, or the use of natural water drop to the pressure of water to the need to irrigate the land, and then through the sprinkler (nozzle) into the air split into small Water drops, evenly fall in the field for irrigation. According to the analysis, for general soil, compared with the traditional surface irrigation methods, the use of sprinkler irrigation technology, food generally can increase 10% to 20%, economic
