As one of the key components of drip irrigation technology， the existence of sediment particles seriously affects the service life of emitters and restricts the popularization of drip irrigation technology. In this paper， two kinds of patch drip irrigation emitters are used as research object， and the anti-clogging performance experiment is carried out in the laboratory. The dynamic changes in emitters’ clogging characteristics (Dra， Cu) were statistically analyzed. The movement mechanism of emitter clogging and discharging sediment was studied. The effects of emitter structure and position factors on emitter clogging were analyzed. The results show that: (1) The pressure-compensated emitter has better anti-clogging performance， and its service life is 227.8% of the labyrinth channel emitter. (2) Single structural factor can not evaluate the anti-clogging performance of emitters. All factors causing emitter clogging should be considered comprehensively. (3) All emitters have sensitive clogging sediment inside， but only when sediment content is high can it easily cause blockage. The results show that when the sensitive sediment content is 5.46% and 5.54%， it does not affect the clogging characteristics of the emitters. (4) The discharge of sediment V90 from the emitter is affected by the accumulation effect of clogged sediment. The experimental results show that the emitter can discharge up to 50% of the accumulated clogged sediment without clogging. In comparison， the emitter with clogging can only discharge up to 25% of the accumulated clogged sediment. These results could provide references for the application and promotion of drip irrigation technology.
