| 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。 It is currently the most effective water-saving irrigation method in arid and water-deficient areas, and its water utilization rate can reach 95%. Compared with sprinkler irrigation, drip irrigation has higher water-saving and yield-increasing effect. At the same time, it can combine fertilization and increase fertilizer efficiency more than twice. 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 can be used for fruit trees, vegetables, cash crops and greenhouse irrigation. It can also be used for field crop irrigation in arid and water-deficient areas. The disadvantage is that drippers are easy to scale and clog, so the water source should be filtered strictly. At present, domestic equipment has basically passed the customs, and drip irrigation should be actively developed in areas where conditions permit. |
