摘要
生物炭是由生物质废弃物在缺氧及低氧条件下经热裂解产生的一类难熔的、稳定的、高度芳香化的富含碳元素的固态物质。本文论述了生物炭的特性,重点阐述了生物炭对污染土壤、酸性土壤、盐碱土壤等障碍性土壤改良修复的作用机理,并提出促进生物炭工业化生产和土地利用,是达到废弃物资源化利用,固碳节能减排,应对全球气候变化,实现生态与农业可持续发展的最佳途径。
Bochar is a kind of high-melting, stable and highly-aromatized solid substance with high content of carbon,which produced from biologic waste after thermal cracking in a low or deficient oxygen conditions. This paper described the features of biochar,and particularly gave dissertation to the function mechanism of biochar in improvement of polluted soil, acid soil and alkali soil, at the same time brought forward that facilitating industrialized production and utilization in land improvement of biochar was the most preferred way to utilize waste resources, and to save energy and reduce carbon dioxide emission, and to cope with the global warming and finally actualize sustainable development of economy and agriculture.
