摘要
介绍了磷石膏对盐碱土的改良机理,结合对天津经济技术开发区的盐碱地改良试验介绍了磷石膏的施用方法,并分析了其改良的效果(包括土壤的化学性质,物理性质等),得出了磷石膏能有效的对盐碱土壤进行改良,操作方便,并能提高土壤肥力的结论。
The mechanism of saline and alkaline soil amelioration with phosphorus gypsum was introduced, Combined with experiment of saline and alkaline soil amelioration of Tian Jing Economical Technology Development Area, the usage of phosphorus gypsum was intro- duced, and its amelioration effects including soil chemical property and physical property were analyzed. The result showed that ： phosphorus gypsum could ameliorate saline and alkaline soil effectively, and it operated simply, enhancing the soil fertilization.
