研究了不同打顶方法对填充型烤烟农艺性状(株高、节距、茎围、有效叶数、叶长叶宽)、经济性状(单叶重、烤黄率、产量)和化学成分的影响。结果显示:供试品种在不同打顶方法处理下的化学成分含量适宜,比例较协调。CY9504在现蕾打顶后留杈处理下,产量超过3 750 kg/hm2;南江3号在盛花打顶处理下,产量接近3 750 kg/hm2,能满足填充型烟叶的开发需要。
The effects of different topping methods on agronomic characters (plant height, pitch, stem circumference, number of effective leaves, leaf length and width), economic characters (single leaf weight, ratio of roasted yellow, yield) and chemical composition of flue- . The results showed that the contents of chemical components of the tested varieties under different topping methods were suitable and the proportions were more compatible. The output of CY9504 was more than 3 750 kg / hm2 after the buds were topped and the output was nearly 3 750 kg / hm2, which could meet the development needs of filled tobacco leaves.
