摘　　要：土壤次生盐渍化是设施栽培土壤的主要障碍性问题,严重制约着中国设施农业的健康可持续发展。本文综述了次生盐渍化土壤的理化特性与土壤盐基离子种类,并对次生盐渍化土壤修复研究进展进行了总结。通过归纳分析壳聚糖、甜菜碱和γ-聚谷氨酸的化学特性及在土壤修复中的研究现状,提出设施土壤次生盐渍化绿色化学修复的研究展望。Secondary salinization in facility soil has become one of the main obstacles to the healthy development of facility agriculture.This article reviewed soil physical and chemical characters and types of salt ions of secondary salinization,and the research progress of remediation by summarizing domestic and foreign literature.A new prospect for the green chemical remediation of the secondary salinization in facility soil was discussed by analyzing the characteristics and remediation effect of three green chemical soil remediation agents:chitosan,glycinebetaine and poly-γ-glutamic acid.
