摘要：

为了研究柠檬酸在土壤形成、物质循环等过程中所起的重要作用，笔者综述了国内外近些年来柠檬酸与土壤磷素相互作用的一些研究进展。主要内容包括：（1）柠檬酸的分泌及其分泌机理；（2）缺磷促进分泌柠檬酸分泌状况；（3）柠檬酸对土壤磷吸附的影响；（4）柠檬酸对土壤磷解吸的影响；（5）人工添加柠檬酸减少磷肥投入的效果。在实际生产中柠檬酸对土壤磷素及磷肥的作用研究有待于加强。

Abstract:

In order to study the role of citric acid in soil genesis and material cycle, the advancement of interaction between citric acid and phosphorus had been discussed. The main contents were: (1) citric acid secretion and secretion mechanism; (2) citric acid secretion in phosphorus deficient; (3) effects of citric acid on adsorption of phosphate; (4) effects of citric acid on desorption of phosphate; (5) effects of manually adding citric acid to soils for reducing the application rates of in phosphorous fertilizers. Studies which were related of citric acid to phosphorus and phosphate fertilizer in the actual production remained to be strengthened.
