英文摘要	Emitter clogging is a persistent problem for drip irrigation using treated effluent. To find an effective flushing regime, research was conducted using two water types (treated effluent and fresh groundwater) with two flushing frequencies (every irrigation event and every five irrigation events) and a control (no flushing). Thin-wall laterals with inline-labyrinth emitters were examined. The irrigation duration was 1 h daily for 91 days. Emitter discharge was monitored. At the end of the study, the mean emitter discharge decreased about 9% in the treated effluent treatment, 7-8% in the fresh water treatment and 13% in the control treatment. Flushing was effective in preventing sediment accumulation, and using fresh water reduced emitter clogging better than using treated effluent. But there were no significant differences between the two flushing frequencies. Flushing with fresh water reduced the calcium and magnesium deposits of the emitter, and the changeable water environment discouraged the bacteria growth. Therefore, when treated effluent is used for drip irrigation, emitter clogging should be controlled by flushing with fresh water every five irrigation events.
