摘要
生物炭是生物质在高温厌氧条件下通过热化学分解产生的一种富炭、较高稳定性和高度芳香化的固体材料,因其具有更高的比表面积、孔隙率、呈碱性和丰富的官能团等特点,被广泛用于土壤重金属污染修复与改良.本文介绍了生物炭的改性方法,综述了生物炭对农业病虫害防控、作物产质量、土壤改良、温室气体减排以及控释农药、肥料等方面的作用,分析了现阶段生物炭在农业生产与推广应用中存在的问题,并对生物炭未来在农业领域应用前景和方向提出了新的见解.
Biochar is a carbon-rich, highly stable and highly aromatic solid material produced by thermochemical decomposition of biomass under the conditions of high temperature and anaerobic condition. It has been widely used in the remediation of heavy metal contaminated soil and soil improvement for its specific surface area, porosity, alkaline and rich functional groups. In this paper, the modification methods of biochar were introduced. The control effects of biochar on agricultural pest and disease, the promotion of crop growth, and the reduction of greenhouse gas emission, as well as research on controlled-release pesticides and fertilizer were summarized. Besides, the existing problems in production and promotion of application of biochar in agriculture were analysis. Finally, new insights into the future application prospects and directions of biochar in the agricultural field were put forward.
