生物磷肥制备及应用研究概况

Preparation and Application of Biological Phosphorus Fertilizer

为了给生物磷肥的制备及其更好的应用提供参考,对传统磷肥存在的问题、生物磷肥的特点、优势以及废弃磷矿石在制备生物磷肥上的应用等方面进行介绍。以废弃磷矿石为原料,利用解磷微生物制取生物磷肥,具有作用时间短、条件易控制、肥效高等优势,现已成为废弃磷矿的主要用途之一。可见,利用解磷微生物能将无工业价值的废弃磷矿石转化为生物磷肥。

In order to provide a reference for the preparation of biological phosphorus fertilizer and its better application, we reviewed the prob- lems of traditional phosphate fertilizer, the characteristics and the advantages of biological phosphorus fertilizer and the application of waste phos- phate rock in preparation biological phosphorus fertilizer. Using phosphate-solubilizing bacteria to produce biological phosphorus fertilizer with waste phosphate rock had the advantage of short duration, easy control and high fertilizer efficiency. Therefore waste rock phosphate without com- mercial value can be translated into biological phosphorus fertilizer using phosphate-solubilizing microorganisms.
