Abstract
In order to optimize the grade structure of flue-cured tobacco leaves,we researched the effects of different topping ways on the main chemical compositions( nicotine,reducing sugar,potassium,etc.) in upper leaves of tobacco. The results indicated that the complete topping( treatment 1) caused single-leaf weight to be overweight,nicotine content to be high,potassium content to be low,and sugar-nicotine ratio to be inharmonious. No topping( treatment 4) could reduce nicotine content and increase potassium content,but it led to the decrease in single-leaf weight and reducing sugar content as well as the inharmony of sugar-nitrogen ratio. Partial topping plus reserving 15 buds( treatment 3) increased single-leaf weight,and made sugar-nitrogen ratio harmonious; the nicotine content was lower and potassium content was higher in treatment 3 than those in treatment 4. Therefore,partial topping plus reserving 15 buds was a way to improve the usability of upper tobacco leaves.
