摘　　要：综述了配施有机肥调控土壤磷素有效性的研究进展,总结了有机肥的利用现状及供磷潜力,探讨了合理配施有机肥提高作物高效利用磷的生物学潜力,重点阐释了配施有机肥调控土壤磷形态转化、提高磷素有效性的机制,包括提高土壤有机质含量、减少磷素固定和吸附、调节土壤化学计量比、改善团聚体结构及增强微生物活性等。针对目前中国有机肥利用率较低的现状,对未来研究方向进行了展望。This study reviewed the research progress on regulating soil phosphorus(P)availability by applying organic fertilizers.It summarized the current utilization status of organic fertilizer and their potential to supply P,and discussed the biological potential of rational organic fertilizers application to improve the efficient utilization of P by crops.The focus was on explaining the mechanism of regulating the transformation of soil P forms and improving the P availability by applying organic fertilizers.These mechanisms involved increasing soil organic matter content,reducing P fixation and adsorption,adjusting soil stoichiometric ratio,improving aggregate structure,and enhancing microbial activity.In view of the low utilization rate of organic fertilizer in China,the future research directions were prospected.
