On the basis of theoretical analysis of the biochar function on soil amelioration, this article discussed the origin, development and technological content of carbonization and returning of agro -forestry residue to soil, made emphasis on the current situation of industrialization and future prospect, clarified that biochar based fertilizers and soil amendments should be taken as an effective way in the practical applications. we call for a focus on the development of diversified products which are based on residue derived biochar. Key words 院 agro-forestry residue; biochar; carbonization and returning; soil-amendment; biochar based fertilizer 农业袁尤其是种植业的可持续发展袁是确保国家粮食安全袁促进全社会持续和谐进步的基础遥 当前袁我国粮 食产量已经连续多年保持在5 亿t 以上[1] 袁为保障粮食安全和社会稳定做出了突出贡献遥在未来一段时期内袁我 国
