摘　　要：苏打盐碱土的改良是东北松嫩平原土壤治理的重要目标。综合前人的研究结果,归纳总结了改良剂的作用机理和改良效果,主要类型及应用,以及改良剂在实际使用中存在的问题,也展望了改良剂的应用前景,为今后改良剂的深入研究提供参考。改良剂可分为无机改良剂、有机改良剂、微生物菌剂,组合改良剂的使用效果好于单一改良剂,改良剂的应用对土壤理化性质、结构、养分含量以及微生态环境都有改善,并促进植物生长。提出针对北方旱田盐碱土的改良,新型有机改良剂以及配套改良技术的研发是今后研究的重点。An important goal of soil management in the Songnen Plain is improvement of soda saline-alkali soil.Summing up the previous research results on soil improvement,this article summarized the application types,action mechanisms,improvement effects,existing problems of improvers in soil improvement,and looked forward to the application prospects of improvers,in order to provide reference for future in-depth research.The results showed that improvers could be divided into inorganic improvers,organic improvers,and microbial agents.The use of combined improvers was better than that of single improver.The application of improvers improved soil physical and chemical properties,structure,nutrient content,and micro ecological environment,and promote plant growth.The research and development of new organic improvers were the focus of future research.
