摘　　要：土壤退化和粮食安全问题愈加受到关注,因地制宜、有针对性地施用土壤调理剂,能达到改善土壤物理化学性状、增加土壤养分、钝化重金属等目的。在国内外相关研究的基础上,本研究概述了土壤调理剂及其主要功能,阐述了以天然矿物、工业废弃物、农业废弃物等廉价原料制备土壤调理剂的现状,归纳概括了调理剂在酸化地、盐碱地和重金属污染土壤的改良效果以及对作物的增产效果,指出现阶段研究中存在的问题并提出展望,以期为土壤调理剂进一步的研究和发展提供依据和参考。The problems of soil degradation and food security have been attracted more attention.Applying soil conditioners according to local conditions can improve soil physicochemical properties,balance soil nutrients and passivate heavy metals.Based on the relevant studies,the main function of soil conditioners was reviewed,the research situation of preparing soil conditioners from cheap raw materials such as natural minerals,industrial wastes and agricultural wastes was expounded,the improvement effect of soil conditioners in acidified land,saline-alkali land and heavy metal polluted soil and the effect of soil conditioners on increasing crop yield were summarized.Finally,aiming at the problems,the prospect was put forward in order to provide reference for the research of soil conditioners.
