磷素供应是限制作物产量的重要因子之一,作物对磷肥当季利用率较低,其吸收的磷大部分来源于土壤,从而作物对土壤磷的高效利用成为关注热点问题,本文综述了国内外关于磷肥施入土壤后形态转化及其生物有效性,提高作物对土壤磷素吸收利用机制,解磷微生物对土壤无效磷转化机制等方面研究进展,以期为作物对土壤磷素高效利用进一步研究提供参考。参86。
燐素供應是限製作物產量的重要因子之一,作物對燐肥噹季利用率較低,其吸收的燐大部分來源于土壤,從而作物對土壤燐的高效利用成為關註熱點問題,本文綜述瞭國內外關于燐肥施入土壤後形態轉化及其生物有效性,提高作物對土壤燐素吸收利用機製,解燐微生物對土壤無效燐轉化機製等方麵研究進展,以期為作物對土壤燐素高效利用進一步研究提供參攷。參86。

Soil phosphorus ( P) supply capacity is one of important limiting factors for crops yield.Crop P uptake mainly derives from soil due to the low P fertilizer use efficiency in the season ,therefore,the issue about the efficient utilization of soil P by crops has be-come the research hotspot.The paper summarized the P form transform and bioavailability ,the mechanism of the absorption and utiliza-tion of soil P and the transform mechanism of soil unavailable P under effect of phosphate -solubilizing microorganisms after P fertilizer was applied based on the latest research achievements from all over the world.The objective of this paper is to provide the reference for the further study on the efficient utilization of soil P in the future.
