Abstract: Honghuadajinyuan as experimental material, The agricultural characteristics of tobacco plants, conventional chemical composition and others were determined. The results displayed that the effects of different treatments on the agronomic characters of tobacco plant, physical properties and appearance score of original tobacco were not obvious. The contents of starch, total sugar and reducing sugar in S1 and S3 were higher than that in S2, S4 and S5, and the contents of total nitrogen, volatile base, chlorine ion and potassium in S2, S4 and S5 were higher than that in S1 and S3. From the perspective of quality of tobacco leaves, there was no significant difference in appearance quality among treatments. The content of carbohydrate in the leaves was increased and the content of nitrogenous compounds was decreased.
