摘要: 滴灌技术是当前农业节水的主要方式之一,由于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。本文综述了灌溉制度、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。

Abstract: Drip irrigation technology is one of the main ways to save water in agriculture at present. As a result of the strong surface evaporation in semi-arid regions, the risks of surface soil salinity accumulation and secondary salinization have been enlarged especially in calcareous soil regions. This paper reviewed the effects of irrigation practice, field management, and soil texture factors on soil water and salt transport as well as secondary salinization. In view of the development of water-saving irrigation in semi-arid area at present, we put forward some research directions that need to be further strengthened, such as the rule of soil water-salt migration under drip irrigation, the effect of soil salt accumulation, and the ways to prevent secondary salinization in order to provide theoretical references for agricultural water conservation and sustainable land use in semi-arid regions.
