摘　　要：滴灌技术是当前农业节水的主要方式之一。半干旱地区地表蒸发强烈,导致农田土壤盐分表聚及次生盐渍化的发生风险增大,在石灰性土壤地区尤为明显。笔者综述了灌溉制度、田间管理、土壤质地等因素对土壤水盐运移及次生盐渍化影响,并针对目前半干旱区节水灌溉的发展,提出了明确滴灌条件下土壤水盐运移规律、土壤盐分累积效应以及防止次生盐渍化调控途径等需要进一步加强的研究方向,以期为半干旱地区农业节水和土地可持续利用提供理论参考。Drip irrigation is one of the main ways to save water in agriculture at present.Due to the strong surface evaporation in semi-arid areas,the risks of surface soil salinity accumulation and secondary salinization in farmland has increased,especially in linestone soil areas.The effects of irrigation system,field management,and soil texture on soil water and salt migration and secondary salinization are reviewed in this study.In view of the development of water-saving irrigation in semi-arid areas,we suggest that research on the law of soil water and salt migration,soil salt accumulation effect and ways of preventing secondary salinization should be strengthened to provide reference for agricultural water saving and sustainable utilization of land in semi-arid areas.
