摘　　要：作为一种高效的节水灌溉技术,滴灌被广泛应用于大田、果园和温室。然而在应用过程中,滴头堵塞问题却严重限制了这一先进灌水技术的推广和应用。针对这一现象,就滴头产生堵塞的机理、堵塞类型等及应采取的预防措施进行了探讨与总结。As an efficient technology of irrigation, dripping irrigation is applied in farmland, orchard and greenhouse broadly. While during the process of application, the clogging of dripper places a restriction on the spread. In view of that, the article makes the discussion and summary about the mechanism and type of clogging and measures to prevent clogging and so on. [
