| 摘 要： | 通过大田试验，研究了不同留叶数（每株留叶16、20、24片）对美引NC297烤烟新品种生长及产质量的影响，结果表明：随着留叶数的增加，烟株株型与上部叶面积有明显的差异；留叶数的多少对中、下部叶片大小和单叶重的影响较小，对上部叶的影响较大；留叶数偏少，烟叶的产量会受到一定的影响，而留叶数过多，均价、上等烟比例将受到不利影响。综合产、质量效益，NC297以留叶数20片为最佳。

| Abstract: | By field experiment, effects of different remained leaf number on the growth, leaf yield and quality of flue-cured tobacco, the results showed that inter node of the flue-cure tobacco was increased with increasing the remained leaf number. remained leaf number would be more influence on leaf weight .The yield will be decreased by keeping less leaves per plant, but keeping more leaves will influence on the average price and the rate of high and middle class leaf. Generally, keeping twenty leaves per plant was acceptable, which would provide more yield, good quality and industry usability of tobacco leaf. |
