滴灌带的作用
The role of the drip irrigation zone
滴灌较喷灌具有更高的节水增产效果，同时可以结合施肥，提高肥效一倍以上。可适用于果树、蔬菜、经济作物以及温室大棚灌溉，在干旱缺水的地方也可用于大田作物灌溉。其不足之处是滴头易结垢和堵塞，因此应对水源进行严格的过滤处理。国产设备已基本过关，有条件的地区应积极发展滴灌.
Drip irrigation has higher water saving and yield increasing effect than sprinkler irrigation, and it can increase fertilizer efficiency more than twice with fertilizer application. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouse, and can also be used for irrigation of field crops in areas where drought and water shortage are needed. The shortcoming is that the dripping head is easy to scale and block, so the water source should be filtered strictly. Domestic equipment has basically passed, and drip irrigation should be developed actively in areas with conditions.
