Based on the field experiments carried out in Yangling, the values of irrigation performance were simulated by the WinSRFR software, and the influence of border length, field slope, unit discharge and cutoff time on irrigation application efficiency, distribution uniformity and storage efficiency were analyzed. On this basis, combined with uniform design and multiple regression analysis，a single-objective optimization model was established including irrigation application efficiency, distribution uniformity and storage efficiency, and taking unit discharge and cutoff time as variables. The model was solved by genetic algorithms, the optimized combination of irrigation technique element under different theories of water requirement were proposed in Wangshang Village, the results show that it can realize a high irrigation performance and water saving for border irrigation through a proper selection of unit discharge and cutoff time.
