Abstract: 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.

Key words: biomass carbon, tobacco field, soil improvement, fixing carbon and reducing discharge, technological approach
