秸秆生物质炭农业领域应用研究进展

Progress in the Study of Straw Biochar Application in Agriculture

秸秆炭化还田是近年来兴起的一项新的农业技术措施,是一种新的土壤可持续管理途径.秸秆炭化还田是破解我国资源环境约束和保障国家粮食安全的必然选择,符合当前我国绿色发展和循环经济的国家需求.本文在总结近年来施用生物质炭对作物生长和产量、土壤理化及其生物学性质、农田主要温室气体排放等影响方面的研究进展基础上,提出生物质炭的施用对于农田生态系统的影响存在显著个体差异,生物质炭的结构性质与生物质炭-土壤-作物相互关系的基础研究是未来土壤可持续管理中的重要研究方向.

The carbonization of straw is a new technology measure for sustainable soil management. Straw carbonization is an inevitable choice to solve the constraints of China＇s resources and environment and ensure national food security, which meets the national demand of green development and circular economy. Based on the summary of recent studies on the effects of biomass charcoal application on crop growth and yield, soil physical and chemical properties, and main greenhouse gas emissions in farmland, we put forward that there are significant individual differences in the effects of biomass charcoal application on farmland ecosystems, and the structural properties and biology of biomass charcoal. The basic research on the relationship between carbon, soil and crop is an important direction in the future sustainable soil management.
