滴灌带的作用： Drip irrigation: 它是目前干旱缺水地区最有效的一种节水灌溉方式，其水的利用率可达95%。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。目前，国产设备已基本过关，有条件的地区应积极发展滴灌。 It is the most effective method of water-saving irrigation in arid water area, and its water utilization can reach 95%. Drip irrigation is more effective than sprinkler irrigation, and can be combined with fertilizing and more than doubling. It can be used for fruit trees, vegetables, economic crops and greenhouse irrigation, and can be used for crop irrigation in areas where drought is scarce. The downside is that the droplets are easily fouled and blocked, so the water supply is strictly filtered. At present, the domestic equipment has passed the basic pass, the area that has the condition should actively develop drip irrigation.
