土壤解磷细菌解磷机制及其促生作用综述

Review of Phosphorus-Resolving Mechanism and Growth-Promoting Function of Soil Phosphorus-Solubilizing Bacteria

磷是植物生长发育必须的营养元素之一,也是植物生长的一个主要限制因子.土壤中的解磷细菌可将难溶性磷转化为可溶性磷,为植物提供丰富的磷.本文对土壤解磷细菌的种类与分布、解磷机制及其促生作用等方面进行了综述,为进一步研究和应用解磷细菌提供参考.

Phosphorus is not only an essential element,but also a limiting factor for plant growth.The phosphate-solubilizing bacteria(PSB)in soil can promote the transformation from insoluble P to available P,which increases P uptake by plant.Herein,the diversity and distribution of PSB,the mechanism of P solubilization,and its promotion effect on plant growth were reviewed in this paper,which provided reference for the further research and application of PSB.
