生物炭在农业上的研究进展

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。

Research Advance of Biochar in Agriculture Field

In recent years,with the emergence of increace production on black earth in Amazonian,the investigation on biochar has been deepened,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 abandoned biomass was made into biochar,not onty 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 properly and corp growth were mainly discussed.
