摘　　要：滴灌的堵塞问题一直是困扰滴灌技术应用与发展的限制性因素,为了探索解决或者预防该问题的技术途径,从堵塞的成因、机理以及预防措施等方面进行了论述,提出了预防灌水器堵塞的基本措施,包括改进灌水器流道结构、强化水质处理以及严格过程管理。在此基础上,对今后的重点研究方向提出了若干建议。Clogging of emitter has been and continues to be a major restriction with the use and development of trickle irrigation systems.In order to explore ways to solve and prevent the clogging problem,our paper reviews the analysis of the plugging in drip irrigation systems by many scholars at home and abroad(respects about mechanism and cause of emitter plugging and its prevention).Then,we list some practical and basic plugging prevention methods and assumptions: there are basic approaches: 1) optimizing the structure of emitter channels;2)improving the water quality;3) keeping a strict hand over the good system design and management.On this basis,List related views for anti-clogging performance of dripper emitter's development direction and advices for recommendations.
