In order to probe influence of chemical components in the flue-cured tobacco during different stages with different topping, it is researched in this paper for the dynamic analysis of main carbohydrate and nitrogen compounds in different stalk position of flue-cured tobacco strain K326 after topping on budding period, the first flower and full flower period. The experimental results indicate that topping to accumulation of chemical components in tobacco leaves have the obvious regulation, which the effect of regulating in the middle and upper leaves is more than the lower leaves; regulating action to starch, soluble sugar protein and nicotine on topping of budding period is greatest, secondly on the first flower period, regulation capability of chemistry component on full flower period is smaller. Considering coordination of chemistry component and increasing flavor precursor in tobacco leaves, Topping around the first flower period in the flue-cured tobacco production is relatively suitable.
