High-throughput sequencing of root zoon soil of tobacco K326 of treatments with original soil (OEE ), no biochar and biochar of 0. 75,1.5,2.25 t/ha were done,and the diversity and composition of bacteria were analyzed,so as to provide reference for improvement of mountain soils by biochar. The results showed that, compared with CK, Chaol, Shannon indices of treatments with biochar decreased, the community abundances of Proteobacteria, Chloroflexi, Armatimonadetes increased, the community abundance of Acidobacteria decreased, the community abundance of Saccharibacteria, Gemmatimonadetes and Actinobacteria changed with the application rates of biochar. There was higher similarity for dominant phyla composition among treatments with biochar, but lower between OEE and treatments with biochar, the similarity for dominant phyla composition between CK and treatments with biochar was higher than that between OEE and treatments with biochar.
