摘　　要：生物炭是一种新型土壤改良剂,具有多种特性,包括较高的pH值、大比表面积、丰富的孔隙结构和表面官能团,因此在贫瘠土壤改良方面逐渐受到学者们的关注。结合国内外在生物炭对不同贫瘠土壤(酸性土壤、盐碱土壤、沙质土壤)理化性质、养分利用和微生物结构等方面的最新研究,总结了生物炭在不同类型土壤改良中的作用机制,对生物炭在贫瘠土壤改良方面的应用前景进行了展望,以期为生物炭改良贫瘠土壤的理论研究和应用推广提供参考。Biochar is a new type of soil amendment,which has various characteristics,including a high pH value,large specific surface area,rich pore structure,and abundant surface functional groups.Therefore,it has gradually attracted scholars attention to improving poor soil.Combined with the latest researches on the physicochemical properties,nutrient utilization and microbial structure of different poor soil(acid soil,saline-alkali soil,sandy soil)at home and abroad,the mechanism of applying biochar in the improvement of different types of soils was summarized,and the application prospect of biochar in improving poor soils was prospected,which provided a reference for the theoretical research and application of biochar to improve poor soil.
