摘　　要：本文通过研究冬灌对塔里木灌区盐分运移的影响,得出随着冬灌定额的增加,土壤的PH值、总盐及盐分组成等变化趋势不同的结果。结合本地区的地下水位、棉花苗期的耐盐性等因素,得出适合本地区的冬灌定额为3500m3/hm2。This paper studies the effects of winter irrigation on salt movement in the Tarim irrigation area.The results show that with the increment of winter irrigation norm,it has different variation tendency with PH value,total salt and salt component.Considering groundwater level and salt tolerance of cotton seedling,it is concluded that 3500m3/hm2 is feasible to be used in the Tarim irrigation area.
