生物质炭化还田作为土壤改良与循环农业的技术途径分析

Analysis of biomass carbonization and conversion to fields as a technical approach to soil improvement and circular agriculture

循环农业与绿色低碳是生态文明建设的重要途径。生物质炭化还田在土壤改良与循环农业等方面具有良好的发展潜力。土壤中施入生物质炭是通过改善土壤理化性质、提高土壤肥力、修复土壤污染等方式对农业土壤生态系统功能产生影响。围绕生物质炭理化特性及炭化还田改良土壤这一基本途径,系统分析了生物质炭用于改良土壤的研究现状,明确了生物质炭改良植烟土壤所具有的突出优势,提出了生物质炭化还田技术利用模式,探讨了生物质炭在植烟土壤保育和营养管理等方面的潜力。

Circular agriculture and green low carbon is an important way of promoting the construction of ecological civilization.Agriculture to biomass returning carbonized has good development potential in soil improvement.The application of biomass charcoal in soil has an impact on the function of agricultural soil ecosystem by improving soil physical and chemical properties,improving soil fertility and remediation of soil pollution.Based on the physicochemical properties of biomass charcoal and the basic approach of carbonization returning to the field to improve the soil,the research status of biomass charcoal used in soil improvement was systematically analyzed,and the outstanding advantages of biomass charcoal in improving tobacco planting soil was identified.The utilization model of biomass carbonization technology was proposed,and the potential of biomass carbon in tobacco planting soil conservation and nutrition management was discussed.
