有机物料在农业生态系统养分循环及其持续生产中具有重要作用,研究有机物料中的磷素,对于深入了解土壤-植物系统中磷的养分循环特征具有重要意义.本文结合国内外已有成果和最新研究进展,从有机物料中的磷素组成,植物的有效性及对土壤磷库的影响等几个方面进行了综述,并探讨了这部分磷素研究过程中存在的问题和今后研究热点.
Phosphorus (P) in organic material plays an important role in the nutrition cycling and sustainable production in agro-ecosystem, and the study on P of organic materials is vital for understanding deeply the cycle characteristics of P nutrient in soil-plant system. This paper summarized composition of P in organic material, its availability to plant and effect on P pool in soil, combining the latest research achievements at home and abroad about P in organic material. The existing problems and the main study direction on the future research were also discussed.
