Abstract
Throngh field experiment, the effects of the number and method of different remained leaf on the growth,leaf yield and quality of flue-cured tobacco variety K326 were studied. The results showed that the height of the flue-cure tobacco increased with increasing remained leaf number of brance tobacco when remained leaf number of the stems was the same. Girth and pitch ?f stem were influenced little. Remained leaf number had great impact on the lower leaves. The length and width of the lower leaves increased with increasing remained leaf number of brance tobacco when remained leaf number of the stems was the same, but the middle and upper leaf pf flue-cured tobacco were not appreciably affected. The method of remained leaf had a small influence on economic index and other characters except plant height when total remained leaf number was the same. The yield and output would be decreased by keeping less leaves per plant,but keeping more leaves would influence on the average price and the rate of high and middle class leaf. Generally,keeping twenty four leaves per plant for K326 was appropriate.关键词
