喷灌是一种先进的灌水技术。对于某些场地和作物,如苗圃、温室、蔬菜、茶叶以及其它一些娇嫩的阔叶经济作物,要求喷头喷洒的水滴细小,就是雾化要好,不致伤害作物。这种喷头一般工作压力较低,在利用自然水头的梯田喷灌系统的低压区,也可安装使用。延河1·10型喷头(图1)就是针对上述要求研制的,其技术 Sprinkler irrigation is an advanced irrigation technology. For certain sites and crops, such as nurseries, greenhouses, vegetables, tea leaves and other delicate, broad-leaved cash crops, the water droplets sprayed by the spray nozzles need to be fine enough to atomize them without damaging the crops. This nozzle is generally low pressure, in the use of natural head of the low-pressure irrigation area of ​​the terraced system, can also be installed to use. Yan River 1 · 10-type nozzle (Figure 1) is developed for the above requirements, its technology
