解磷微生物及其在盐碱土中的应用研究进展

Phosphate Solubilizing Microorganisms and Application Progress in Saline-alkaline Soil

解磷微生物能够将土壤中难溶性磷酸盐转化为可供植物吸收利用的磷,在提高土壤有效磷含量、缓解植物盐碱胁迫损伤及修复盐碱土中表现出良好的应用前景。本文从解磷微生物的研究及应用现状入手,综述了盐碱土中解磷微生物的分离、解磷机制,同时阐述了盐碱耐受性和解磷能力关系及其在盐碱土修复中的应用进展,以期为利用耐盐碱解磷菌缓解植物盐胁迫损伤及修复盐碱土提供重要参考。

Phosphate-solubilizing microorganisms(PSMs)are a group of plant growth-promoting rhizobacteria,which can dissolve insoluble phosphates and increases P uptake by the plant as well as improve properties of saline-alkaline soil.In this article,the PSMs and their application research status were briefly reviewed.The research status of PSMs in saline-alkaline soil including the halotolerant varieties,saline-alkali tolerance,phosphate-dissolving abilities and mechanisms,especially their roles in saline-alkaline soil remediation were comprehensive reviewed.It was expected to provide an important reference for the use of saline-alkali tolerant PMS to alleviate plant damage under salt stress and remediate saline-alkali soil.
