Abstract: Soil is one of the important ecological factors for plant growth. Soil quality has a direct influence on the growth and development of tobacco. Due to the unreasonably using of land, a series of prolems appeared in tobacco soil, some achievements have been made on the research of tobacco soil remediation in recent years. This paper introduced the green manure，biological activated carbon, reusing of crop straws, microbial fertilizer and other improvement measures to tobacco soil repair status, and mainly analyzed from the soil physical and chemical properties, soil nutrients, soil microbial diversity and enzyme activities. Combining with the improvement of tobacco soil conditions in recent years, this paper analyzed  the existing problems, and put forward some suggestions for future research, for example, reseach depth of soil improvement materials and application of modern biotechnology, hoping to provide research approaches for the remediation of tobacco soil in the next step.

Key words: tobacco planting soil, soil restoration, green manure, reusing of crop straws, biomass charcoal, microbial fertilize
