生物炭对作物增产与温室气体排放研究综述

Review on Impacts of Biochar on Crop Yield and Greenhouse Gas Emission

生物炭是由含碳量丰富的生物质在无氧或限氧的条件下低温热解而得到的1种细粒度、多孔性的碳质材料,在能源、环境、农业等多个领域都有巨大的应用价值,已成为当前的研究热点。目前全球气候变化对人们生存生活产生的影响已经成为全球化问题,农田作为温室气体重要排放源的同时也作为粮食的重要来源,一直受到各国政府的高度重视。该文探究了生物炭对农田粮食增产与温室气体减排等研究热点,梳理了相关研究成果,并提出两者结合研究的方向性建议。

Biochar is a kind of fine size and porous carbonaceous material obtained by pyrolysis of carbon rich bio-mass at low temperature without oxygen or oxygen limitation. It has great application value and functions in manyfields such as energy,environment and agriculture,and has become the current research hotspot. At present,the im-pact of global climate change on people＇s livelihood has become a global issue. As an important source of greenhousegas emissions,farmland is also an important source of food,which has been highly valued by governments and localresearch departments. In this paper,biochar is combined with several research hotspots of increasing crop yield andreducing greenhouse gas emissions,and relevant research results are sorted out,and the directional suggestions ofthe research are proposed.
