摘　　要：磷肥的低利用率不仅会造成直接的经济损失,而且对人们赖以生存的环境产生不良后果。因此如何提高磷肥当季利用率、减少因磷肥损失带来的环境污染是长期以来全球共同关注的课题。磷素活化剂的研制和应用是改善我国磷肥利用率低、磷素固化严重现状的有效途径之一。它能有效地提高土壤中磷素利用率,减少磷肥施用量,缓解磷资源不足的矛盾,具有远大的发展前景。本文总结了磷素活化剂的种类及各种活化剂的作用机理和作用效果,并展望了今后的研究方向。The low utilization rate of phosphate fertilizer will result in not only direct economic losses,but also the adverse consequences for human survival environment.Therefore,the global topic subject is how to improve the seasonal utilization of phosphate fertilizer and reduce environmental pollution.The phosphorus activator is an effective way which improves the low utilization rate of phosphate fertilizer and the serious fixation of phosphate status.Phosphorus activator effectively improves the utilization rate of soil phosphorus,reduces the amount of phosphate fertilizer,and alleviates the contradiction of insufficient resources.So it has a broad prospect for development.This paper summarized the types of phosphorus activator,the mechanism and effects of various activators and also predicted the future research directions.
