The irrigation process under different combinations of border irrigation technology elements was simulated to obtain the corresponding border irrigation performance index values, and determine the minimum irrigation quota under different combinations of border irrigation technology elements in North China Plain. Combined with the current situation of border irrigation in North China Plain, the border length, slope, field leveling accuracy, micro-topography spatial distribution difference and border unit width flow were taken into account, including 53088 border irrigation technology elements in total. The whole field was covered with the surface irrigation water, the minimum irrigation depth Zmin>0 was taken as the control condition, and the SISM model was taken to simulate the irrigation process under the combination of different technology elements, analyze the corresponding relationship between border irrigation technology elements and irrigation performance index values, and by combining with the test results of border irrigation numerical simulation and relevant regulations of surface irrigation, the recommended range of border irrigation elements under three representative lengths of border field 50 m, 100 m and 150 m (such as field leveling accuracy Sd, slope Sp, and unit width flow q) was proposed. The minimum irrigation quota of three representative border lengths should not be lower than 84 mm, 117 mm and 148 mm under normal conditions, and the minimum irrigation quota of three representative border lengths should not be lower than 71mm, 75mm, and 79 mm under the optimized conditions.
