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 of phosphate fertilizer not only causes direct economic losses, but also has adverse consequences for the environment in which people depend. Therefore, it has been a common concern in the world to improve the seasonal utilization of phosphate fertilizer and reduce the environmental pollution caused by the loss of phosphate fertilizer. The development and application of phosphorus activator is one of the effective ways to improve the low phosphorus utilization rate and the serious status of phosphorus curing in our country. It can effectively improve the utilization of phosphorus in the soil, reduce the amount of phosphate fertilizer, phosphorus resources to alleviate the contradiction, with great prospects for development. This paper summarizes the types of phosphorus activators and the mechanism and effect of various activators, and looks forward to the future research direction.
