摘　　要：从3个角度综述了生物质炭对土壤磷素调控的相关研究进展,包括生物质炭处理下土壤对磷素的吸附固定特性,生物质炭对土壤稳定态磷的活化机制,以及生物质炭对土壤磷素的长效调控机制及其影响因素。目前生物质炭对土壤磷有效性影响的调控机制认识不足,,需要系统性的研究生物质炭-土壤-作物之间的互作及其非生物与生物调控过程,同时综合考虑土壤性质和生物质炭原料等影响因素,为农业生产中的合理利用生物质炭保障农业可持续发展提供理论基础。This paper reviews the effect of biochar amendment on soil phosphorus availability,including the adsorption mechanism of biochar treated soil,the activation mechanisms of biochar on soil stable phosphorus,the long-term regulation mechanisms as well as the potential influencing factors.So far we haven’t had sufficient understanding of the mechanisms of biochar amendment on soil P availability,therefore,a systematic study is needed on the interaction between biochar-soil-crop,and on the abiotic and biological regulatory mechanisms,and the influencing factors such as soil properties and biochar feedstock.Should be comprehensively considered so as to provides a theoretical basis for the rational utilization of biochar in agricultural production to guarantee the sustainable development of agriculture.
