土壤有机质中的磷素必须经过矿化并成为可溶性状态时,才能被作物吸收利用。本文介绍如何从有机土壤及微灰化土壤中,分离的细菌可以矿化有机磷素。用选择的培养基,以卵磷脂或核酸作为磷素的来源,用威诺格拉斯基矽酸膠的选择分离,所得菌种经形态和生理特性的鉴定,并通过矿化磷素接种试验证明,是强度矿化有机磷——卵磷脂或核酸——的磷细菌。分述如下:
Soil organic matter in the phosphorus must be mineralized and become soluble, can be absorbed by crops. This article describes how bacteria isolated from organic soils and slightly ashed soils can mineralize organic phosphorus. With the selected medium, lecithin or nucleic acid was used as the source of phosphorus, and Separation with Winograssia gum was selected. The obtained strains were identified by morphological and physiological characteristics and proved by mineralized phosphorus inoculation test , Is an intensely mineralized organophosphorus - lecithin or nucleic acid - phosphorous bacterium. As follows:
