为探究非生育期北疆不同滴灌年限棉田在冻融过程中的土壤盐分运移规律，选取新疆生产建设兵团石河子121团炮台实验站6块不同年限棉田，对各地块在冬季的盐分运移规律进行了研究。结果表明，冻融期内，各年份棉田土壤盐分含量基本呈现出随种植年限的增长而减小的趋势，各地块土壤盐分含量表现为中等变异性和强变异性，土壤盐分聚集区有从表层向深层迁移的特征。

In order to investigate soil salt movement law in the process of freezing and thawing with dif-ferent irrigation years during non-growth period in North Xinjiang,six cotton fields with different years were selected in Shihezi Agricultural Division of Xinjiang Production and Construction Corps.The result in-dicated that during the freezing and thawing period,soil salt content in cotton fields were decreasing with the increasing of planting years,and the relative soil salt content showed moderate variability and strong variability.Besides,soil salinity accumulation area moved from the surface to the deep with the increasing reclaimed years.
