生物炭对农业土壤及作物生长影响的研究进展

A Review of the Effects of Biochar on Agricultural Soil and Crop Growth

生物炭是一种高效利用废弃生物质材料,在缺氧或厌氧条件下经过高温炭化得到的多孔富碳黑色固态物。生物炭的研究推广不仅可以促进废弃生物质资源再利用,且对土壤固碳培肥有巨大潜力。本文综合前人研究成果,探究了生物炭对土壤物理性质、化学性质及生物性质的改良作用和对作物生长的促进效果,同时对生物炭需要进一步研究的科学问题和应用前景提出了展望,旨在为废弃生物质资源化利用提供思路,为广泛应用生物质炭化技术提供借鉴和参考。

Biochar is a porous carbon-rich black solid obtained by high-efficiency carbonization of waste biomass materials under anoxic or anaerobic conditions.The research and promotion of biochar not only promotes the reuse of waste biomass resources,but also has great potential for soil carbon sequestration.This paper explored the effects of biochar on the physical,chemical and biological properties of soils and the promotion of crop growth based on the previous research results.At the same time,it also proposed a prospect for the scientific research of biochar and its broad application prospect,which.providing ideas for the utilization of waste biomass resources,and reference for the extensive application of biomass carbonization technology.
