Abstract:

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.

Key words: secondary salinization, green chemical remediation, chitosan, glycinebetaine, poly-γ-glutamic acid
