【摘要】 炭化还田是农林废弃物资源化循环利用的有效技术手段之一,也是土壤改良的新途径,对促进农业低碳、循环、可持续发展具有重要意义。以生物炭为核心,从其改良土壤的理论基础分析入手,综合评述了炭化还田技术的由来、发展与技术内涵,着重介绍了炭化还田技术的产业化发展现状和前景,明确了炭基肥料和炭基土壤改良剂是炭化还田的有效技术载体,国家应在炭基多元化产品开发方面给予高度重视。更多还原

【Abstract】 Carbonization and returning is one of the effective technological means in recycling utilization of agro-forestry residues and soil amelioration,and it has important meaning to promote low carbon circulation and sustainable development of agriculture.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.更多还原
