Based on field experiments carried out in Yangling,field application efficiency is simulated by SRFR software and simulated values are then compared with measured values.Results show that the margin of error is reasonable,indicating that SRSF software is appropriate for the analysis of border and furrow irrigation.According to the simulation by SRSF software,optimum combination of reasonable irrigation technique elements under different conditions of border irrigation and furrow irrigation is found through changing the combination of irrigation technique elements.The result from the study may be useful in avoiding waste of water resources,enhancing irrigation application efficiency and distribution efficiency,and attaining aim of saving water.Meanwhile,the method can provide some references for other regions to formulate a scientific irrigation scheme.
