生物质炭对农田土壤的影响

Effects of Biochar on Agricultural Soil

生物质炭具有丰富的孔隙结构和表面性能、巨大的比表面积、植物生长所需营养元素、较高的化学稳定性和较强的阳离子交换能力等特点,因而其在土壤改良、污染物吸附、固碳减排、土壤修复等领域具有特别大的应用前景。该文概述了生物质炭的作用及其研究进展,同时指出,目前生物质炭应用技术的研究还处于起步阶段,生物质炭的研究工作还有待于深入和加强。

Biochar has abundant pore structure and surface properties,large specific surface area,high plant growthnutrient contents,high chemical stability,and strong cation exchange capacity. Thus,biochar has a special wide ap-plication prospect on soil improvement,pollution absorption,carbon sequestration and mitigation and soil remedia-tion fields. Although some progress has been made in biochar research,but the application technology research isstill in its infancy and has yet to be further and strengthened.
