The study showed that 10 sites tobacco existed differences between chemical composition, tobacco main routine chemistry compatibility was good, besides the sugar than alkali and nitrogen than alkali of X2F was high, overall performance for two sugar small, potassium than chloride high; Tobacco aromas material content was different degree; There was slightly difference among different area in the sensory quality indexes and comprehensive score, X2F from Jiujia township slightly a comprehensive tall score, C3F from Yunxian township slightly a comprehensive tall score, B2F from Yutang township slightly a comprehensive tall score; With 10 sites tobacco chemical composition and sensory quality inspection data analysis of principal component analysis concluded that produces can be divided into 3 types of tobacco.
