Abstract：[Objective]Attempt to explore the quality of border irrigation and the best border check specifications in Zuncun in Yellow River irrigation district.[Method]A field experiment was conducted from May 2015 to De-cember 2016 at the irrigation area in Shanxi Province. The technique applied was referred to as border irrigation. In this paper, the advance and recession of the irrigation water was recorded. And the irrigation performance was calculated and simulated with WinSRFR4.1, a software for simulating surface irrigation system.[Result]The re-sults showed that irrigation efficiency and irrigation uniformity cannot satisfied the requirement of water saving, and the shortage of irrigation and the excessive irrigation was common in the irrigation area. Simulation results showed that the longer the boder length the more difficult it is to meet the requirements of water saving irrigation.[Conclusion]Then the paper concludes with new border dimensions to improve the quality of irrigation, as fol-lows:the width is 2 meters, the length is 280～340 meters;the width is 3 meters, the length is 240～270 meters;the width is 4 meters, the length is 170～240 meters;the width is 5 meters, the length is 130～170 meters;the width is 6 meters, the length is 110～140 meters. The results have theoretical value for border irrigation and have practical value for water management in Zuncun Yellow River District.
