生物炭在农业上的研究进展

Research Advance of Biochar in Agriculture Field

近年来,随着亚马逊黑土增产作用的出现,对于生物炭的研究不断深入,发现其良好的理化性质可作为土壤改良剂、肥料缓释载体及碳封存剂,开始成为农业领域的研究热点。生物炭农用是碳减排的过程,将废弃生物质生产成生物炭,不仅解决了废弃生物质问题,而且给农业生产带来显著效果。通过国内外有关研究成果的综合分析,重点阐述了生物炭对土壤性质和作物生长的影响。

In recent years,with the emergence of increace production on black earth in Amazonian ,the investigation on biochar has been deep-ened ,and it has been found that its good physical and chemical properties could be used as soil amendment, slow-release carrier for fertilizer and carbon sequestrating agent, and it became a hotspot in agricultural field. Agricultural utilization of biochar can reduce carbon emissions, the aban-doned biomass was made into biochar, not only solve the problem of waste biomass, but also produce a significant effect of agricultural production. Through the comprehensive analysis of the research results at home and abroad, effect characteristics of biochar on soil property and corp growth were mainly discussed.
