磷细菌肥料的研究和应用现状概述

Study of Phosphorus Bacterial Fertilizers and Present Status of their Use

磷细菌肥料是从提高磷素在土壤中的有效性、活化固定态磷资源、实现农业可持续发展等方面着手研制的一种新型的生物肥料。简要综述了国内外有关磷细菌肥料中磷细菌在土壤中的种类分布、解磷机制、菌株的分离筛选、解磷能力的测定方法及磷细菌肥料在农业生产上的应用和意义等方面的研究,并指出了日前仍待解决的问题。

A brief review is given of the study of species distribution in soil of phosphorus bacteria in phosphorus bacterial fertilizers, the mechanism of phosphorus decomposition, the separation and screening of strains, the methods for the determination of phosphorus decomposition capacity and the use and significance of these fertilizers in agricultural production. The problems to be solved yet are pointed out.
