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.
