Abstract: To explore the relationship of the tobacco leaf’s reducing sugar and the main chemical components of soil and tobacco leaf, we studied the influence of 15 kinds of tobacco chemical composition (reducing sugar, nicotine, total potassium, chloride, protein, total nitrogen, total P, Mg, Ca, Fe, Mn, Cu, Zn, K / Cl and sugar / nicotine) and 6 kinds of soil composition (Cu, Zn, Fe, Mn, K and the soil pH value) under two kinds of soil conditions. The results showed that Fe promoted a positive effect on reducing sugar and Ca could restrain the increase of reducing sugar, increased the content of Cu, Zn, Ca and decreased the content of Fe can reduce the reducing sugar content. Moreover, it could optimize the content of volatilizable aroma components and improve the quality of tobacco leaves in south of Anhui province through adjusting the main chemical composition of the soil and tobacco which could be reduced the reducing sugar’s content.
