土壤溶磷微生物的研究进展及应用

Research Progress and Application of Phosphate-Solubilizing Microorganisms in Soils

溶磷微生物是一种能将植物难以利用的磷转换为可吸收状态的微生物,能够通过分泌有机酸、氢离子等降低PH的方式以及酶解作用为植物提供磷元素,可以有效提高土壤中磷的利用率,减少环境污染,对农业可持续发展具有重要意义。本文对溶磷微生物的种类、溶磷机制研究以及溶磷微生物肥料的应用等方面进行了综述,并对溶磷微生物肥料在生产应用中的问题和今后研究的方向进行了阐述。

Phosphate-solubilizing microorganisms are a kind of microorganism that can transform the phosphorus which is difficult to be used by plants into an absorbable state, and can provide phosphorus for plants by reducing PH, including secret organic acids, hydrogen ions and other ways, as well as enzymatic hydrolysis. It can effectively improve the utilization rate of phosphorus in soil and reduce environmental pollution;on the other hand, it is greatly significant to the sustainable development of agriculture. In this paper, the types of phosphate-solubilizing microorganisms, the mechanism of phosphate-solubilizing microorganisms and the application of phosphate-solubilizing microbial fertilizers were reviewed, and the problems in the production and application of phosphate-solubilizing microbial fertilizers and the direction of future research were described.
