作为功能性材料,生物炭在应对耕地质量退化、全球气候变暖和能源危机等问题上表现出了独特的作用。综述了生物炭的理化特性及其在农田应用的效应和作用机理等方面的研究进展,并扼要地分析了生物炭在农业生产中应用的难点和研究方向,以期为生物炭应用和推广提供一定的思路。
As a functional material, biochars demonstrates an effective way on deal with farmland degradation, glob- al warming and energy crisis. In this article, the physical and chemical characteristics of biochars are briefly intro- duced, and the research progresses of application effect and action mechanism in agricultural production are re- viewed. In addition, we also analyze the application difficulty and the research directions of biochars in agricultural production. It would provide some idea of the application and promotion of biochars.
