解磷微生物肥料的研究与进展

Research and progress of solubilizing microbial fertilizer

磷是植物生长必需的矿物质元素之一,在土壤中易被固定降低其有效性。目前,研究和生产含有解磷功能的微生物有机肥料是转化土壤中无效磷、提高磷肥利用率的有效途径之一。叙述了解磷微生物肥料中微生物的种类、生态分布规律和影响高效解磷微生物选育的外部因素,概述了解磷微生物菌肥的应用和研究进展,探讨了解磷微生物肥料的应用价值。为解磷微生物未来的研究重点提出理论依据。

Phosphorus is one of the mineral elements necessary for plant growth, which can be easily fixed in the soil but its effectiveness reduce. However, the phosphorus content of soluble in soil is relatively low in our country. At present, one of the effective way to transform invalid phosphorus in soil and improve the phosphatic fertilizer-use ratio is that microbial organic fertilizer which possess a function of phosphate-solubilizing should be studied and product. It is narrated in this paper that the species and ecological sub-step law of soil phosphate-solubilizing microorganisms and the external factors which influence breeding of efficient phosphate-solubilizing microorganisms. It gave an overview of the use and research to the phosphate-solubilizing microbial fertilizer. It also discusses the application value of the phosphate-solubilizing microorganisms fertilizer and put forward the theories basis for future study on the phosphate- solubilizing microorganisms.
