摘　　要：秸秆高温(厌氧或缺氧)条件下炭化形成生物质炭,其本身具有丰富的孔隙结构、巨大的比表面积、植物所需的营养元素、较高的结构稳定性和较强的阳离子交换能力,还田能促进农田土壤生产力提升。本文综述了生物质炭还田对农田土壤肥力、农作物产量和农田温室气体排放的影响,并展望了生物质炭农业利用前景,以期促进低碳农业发展。Straw carbonization under high temperature(anaerobic or anoxic)conditions forms biochar,which has abundant pore structure,huge specific surface area,nutrient elements required by plants,high structural stability and strong cation exchange capacity,and can promote the improvement of farmland soil productivity.In this paper,the effects of biochar returning on soil fertility,crop yield and greenhouse gases emissions were reviewed,and the prospects of biochar agricultural utilization were prospected to promote the development of low carbon agriculture.

关 键 词：生物质炭 土壤肥力 产量 温室气体
