    摘要:

    20世纪末以来,膜下滴灌技术在我国西北干旱区得到了大规模的推广和应用,极大推动了绿洲农业的发展。然而,滴灌带入盐分无法排出导致的农田土壤积盐问题,使得干旱区绿洲农业的可持续发展面临巨大挑战。如何在水资源短缺的情况下防治农田次生盐渍化和利用西北干旱区广泛分布的盐碱地资源,是我国干旱区农业可持续发展中迫切需要解决的问题。本文结合西北干旱区膜下滴灌农田水盐运移的特点,主要从盐生植物耐盐机制及其生长发育对盐分的响应、盐生植物排盐与盐碱土改良的互馈效应以及种植盐生植物对土壤水盐动态的影响等方面对生物排盐的研究进展进行了比较系统的梳理,同时指出了目前西北干旱区在农田生物排盐研究方面存在的不足,并对今后需要开展的研究工作进行了展望,以期为旱区农业制定合理高效的综合排盐制度提供决策依据,对于实现农田盐分平衡、缓解土壤次生盐渍化危机和土壤可持续利用具有重要意义。

    Abstract:

    Since the end of the 20th century, mulched drip irrigation technology has been widely promoted and applied in arid areas of northwest China, which has greatly pushed the development of oasis agriculture. However, the salt in water brought by drip irrigation cannot be discharged from the soil, which makes the sustainable development of oasis agriculture in arid areas challenging. Therefore, preventing and controlling secondary salinization of farmland to make use of the salt and alkali land resources widely distributed in the arid area of northwest China under conditions of water resource shortage is an urgent problem to be solved in order to promote sustainable development of agriculture. This article sorted literature on biological salt removal and the aspect of salt tolerance mechanism, growth and development of halophytes to salt, mutual feedback effects between salt removal of halophytes and reclamation of saline-alkali soil, and the effects of planting halophytes on soil water and salt dynamics. Also, this study points out the existing problems in the research of biological salt removal in arid areas of the northwest and suggests prospects for further research works. The study can provide decision bases for making reasonable, efficient and comprehensive salt removal systems in arid area agriculture and is of great significance for realizing salt balance in farmland, alleviating soil secondary salinization crisis and soil sustainable utilization.
