Abstract: To produce pause flow in surge irrigation and solve the key technique problems of surge flow irrigation, a new water-saving irrigation technique—the siphon surge flow irrigation with low pressure pipes was put forward based on the principle of siphon.The surge irrigation is realized by using an intermittent flow generating device and a regulating pond to form automatically intermittent flow in the outlet low distribution pressure pipeline. The technique combines surge flow with low-pressure pipeline harmoniously, exerting each advantage fully to attain the best water-saving result. The constitution and each part's function of the system were introduced, and the principle to form intermittent flow was analyzed. Moreover, indoor expriments have been carried out to test the feasibility of the new system which laid the foundation for further field experiment.
