Abstract:

The field trials were studied to improve the usability of upper leaves of flue-cured tobacco Variety K326. The results showed that it was more appropriate to top than the others in flower of central flowers for the normal growth tobacco plants. However, it was more appropriate to branch after topping for the abnormal tobacco plants. Tobacco yields and qualities can be greatly increased by these measures. In a word, it suggests that it is very meaningful for the achievement of better yield and quality for K326.
