Both moisture content and salt content has a smaller dispersion alonge the border head to border tail by saline water surge flow irrigation, yield decreased significantly irrigated by saline water traditional surface border irrigation than that of surge flow irrigation. Both irrigation efficiency and irrigation uniformity were analyzed by SRFR Model, it showed that when the field slope gradient is 0.15%, border length is 200-250m, unit width flux is 3.0～4.0L/m. s, periodic numbers is 3, circulation rate is 1/3, water supply time in one period is 30 min, surge flow irrigation can obtain maximal irrigation degree.
微咸水波涌灌在可以使水盐分布在畦首～畦尾方向上离散度更小,微咸水传统地面畦灌产量比波涌灌有显著降低；采用SRFR模型对灌水效率和均匀度进行分析,显示当田面坡度为0.15%、畦长为200～250m、入畦流量为3.0～4.0L／m.s、周期数为3、循环率为1／3、单次供水时间为30min时,进行波涌灌能达到最高的灌水质量。
