[Objective] The wel peak, deposited salt range and salt absorption ability of salt angle grass were determined, and absorption deposited salt was controlled within the scope. [Method] Taking Ph 7. 9 water as irrigation water, the change process of moist soil body was studied under the condition of different initial moisture content, soil bulk density and flow rate. [ Result] salt angle grass aborbed part of Na * and Cl-to inhibit the salinity- The total salt content within the soilt depth of 20 cm dropped 0. 12 g/kg. F Conclusion ] The research could provide ihe basis for the control of soil salinity of the fringe of the wetting front under the condition of drip irrigation.%[目的] 确定湿润峰、积盐范围及盐角草吸盐能力,控制积盐范围内盐分.[方法] 以pH 7.9的水作为灌溉水源,在不同土壤初始含水率、土壤容重及滴共流量的条件下研究土壤湿润体的变化过程.[结果] 盐角草吸走部分Na+、Cl-抑制盐分,积盐范围内土深20cm处的总含盐量降低了0.12 g/kg.[结论] 该研究可以为有效地控制滴灌条件下湿润锋边缘积累盐分提供依据.
