滴灌系统灌水器堵塞及防堵措施研究进展

滴灌系统灌水器堵塞一直是制约滴灌技术应用推广的关键问题，为探索预防、解决该问题的方法，首先，从灌溉水源、灌水器流道结构、滴灌系统运行方式等方面总结了灌水器堵塞类型，论述了该领域的研究成果；其次，通过控制水源处理、配置合适过滤设备、改进灌水器流道、选用较优系统运行方案等方式提高灌水器抗堵塞性能，提出进一步研究发展灌水器堵塞防治新技术；最后，讨论了目前研究中存在的问题及下一步研究建议，为更好地防治灌水器堵塞问题提供新思路。 

Research Advances in Drip Irrigation Emitter Clogging and Anti-clogging Measures

To prevent and solve clogging issue of drip irrigation emitters，which has always been important，restricted application and promotion of drip irrigation technology，firstly，clogging types of emitter were summarized from aspects of irrigation water source，structure of emitter channel，and operation mode of drip irrigation system，and research results of experts and scholars in this field were discussed.Secondly，anti-clogging performance of emitter was improved by controlling water source treatment，configuring appropriate filtering equipment，improving flow channel of emitter，selecting a better system operation plan，and further research and development of new emitter clogging prevention and control technology was proposed.Finally，problems existing in current study and future research recommendations were discussed，which provided new ideas for better prevention and control of emitter clogging.
