摘　　要：利用生物冶金的方法,将不溶性磷源转化为水溶性或枸溶性磷源,从而提供了一条利用低品位磷矿的新途径。讨论了生物和微生物在磷化工中的研究与应用,介绍了用自制菌磷肥在田间试验所取得的结果,提出了利用生物工程的方法处理低品位磷矿而直接生产磷肥的技术路线。The method of bio-metallurgy is capable of converting insoluble phosphate resources into water or citric acid soluble ones. So it provides a new approach to utilize low grade phosphate ore. In this paper,the investigation and application of organisms or microorganisms in phosphorous chemical industry were reviewed. The good results of field experiments with the home made bacteria-phosphate fertilizer were obtained. The technical road of directly producing phosphate fertilizer by treating low grade phosphate ore with biological engineering method was proposed in the paper.
