摘　　要：生物炭是生物质在高温缺氧条件下热裂解的产物。其具有多孔性、高阳离子交换量(CEC)和低容重特征,对土壤性状改良、环境污染修复和作物生长等方面都有一定的积极作用。生物炭的农业应用作为一种农业碳汇减排和提高土壤生产力技术途径已得到广大学者的关注。现从土壤性状改善、作物生长、生态环境效应方面综述了生物炭的研究进展,基于生物炭的研究方法、范围、内容及推广应用等方面存在的几大问题,展望了生物炭今后的研究趋向与前景,指出生物炭在农业领域中的研究应用存在巨大潜力,以期为生物炭在农业领域的有效应用与推动现代农业可持续发展提供遵循依据。Biochar is the product of pyrolysis of biomass at high temperature under anoxic condition. Porous, high cation exchange capacity （CEC） and low bulk density are main features of bioehar, and it has a positive effect on improvement of soil properties, remediation of environmental pollution and crop growth, etc. As a technology way of reducing agricultural carbon emission and enhancing soil productivity, the agricultural application of biochar has received attentions from scholars. Based on soil improvement,crop growth and ecological environment effects, the research advances on biochar application were reviewed in agricultural fields. Finally, the research prospects and huge potential of biochar in the agricultural fields were pointed through several problems on research methods,scope,content and application of biochar. This study would aim to provide basis of effective use of biochar in agricultural fields and promotion to sustainable development of modern agriculture.
