提高磷矿粉肥效的生物学途径

Biological Route to Improvement in Fertilizer Efficiency of Ground Pho6phate Rock

概要叙述了我国磷矿的大致分类情况和矿物学性质 ,提出了用生物学方法提高磷矿肥效的可能性 ,并介绍了国内外应用解磷微生物的进展 ,提出解决我国磷矿品位较低及氮。

A biief account is given of the rough classification of phosphate rocks in China and theif mineralogical properties. The possibility is suggested of improving the fertilizer efficiency of ground phosphate rock by biological means. An introduction is given to the progress made in the use of phosphatdecsrnposing micro-prganisms at home and abroad Finally, biological countermeasures are proposed to solve the problems of low grade of phosphate rocks in China and uneven ratin of nitrogenous to phosphatic fertilizers applied.
