生物质炭是各种生物质在完全或部分缺氧的情况下经热解炭化后的固态物质,具有高度的芳香性,物理、化学和生物抗分解性。随着炭化工艺的日趋成熟和生物质炭稳定的碳封存效果,大规模转化农业废弃物为生物质炭以应用于土壤改良和生态环境保护成为现实可能,正受到越来越多的研究关注。本文概述了生物质炭的性质特点、稳定性,以及对土壤理化性质、碳氮养分循环和微生物学特性的影响,总结分析了生物质炭对土壤环境质量的影响及应用前景。 Biochar refers to the solid carbon materials produced from slow pyrolysis of biomass under limited oxygen condition which is highly aromatic, recalcitrant to the physical, chemical and biological decomposition processes. Along with the development of carbonization technology and the stable carbon sequestration of biochar, it is realizable to transfer the agricultural waste into biochars for soil amelioration and environment protection, which has attracted more and more concerns. This paper summarized the properties and stability of biochar and its effects on soil physical and chemical properties, carbon and nitrogen nutrient cycling and microbial properties, and analyzed the effects of biochar on soil environmental quality and its application potentiality.
