摘要: 为探明打叶数量对烟叶等级结构及工业可用性的影响,2014—2015年以‘南江3号’为供试品种,研究9种打叶处理下烟叶的单叶干重、鲜干比、经济性状及等级结构。结果表明:(1)随着打叶数量的增加,各处理鲜烟重量、干烟重量、单叶干重增加,其中以清除下部叶4片不适应烟叶,顶部第1~3片不采烤处理的单叶干重最重,鲜干比最低。(2)打顶后清除下部3~4片不适用烟叶,顶部第1~2片不采烤,综合性状表现较好。综合分析认为,陕西省洋县以打顶后及时清除下部4片不适用烟叶和顶部第1片叶不采烤,烤烟产量、产值及等级结构综合表现最好。

Abstract: To find out the effect of different removed leaves number on hierarchical structure of tobacco and industrial availability, field experiments were carried out to study nine kinds of different removed leaves number on leaf dry weight, fresh/dry ratio, economic traits and hierarchical structure of tobacco use ‘Nanjiang No.3’ during 2014 to 2015. The results showed as followed: (1)the fresh weight, dry weight, leaf dry weight, fresh/dry ratio of tobacco gained significant difference among all treatments, and the correlation was positive with removed leaves number. Among them, the yield of the treatment was stable in which the lower 4 pieces of unsuitable tobacco leaves decreased and the upper 1-3 pieces of top leaves uncured,gained the lowest fresh/dry ratio and highest dry weight of tobacco. (2) The yield of the treatment was stable in which the lower 3-4 pieces of unsuitable tobacco leaves decreased and the upper 1-2 pieces of top leaves uncured, quality grade structure was optimal, and the hierarchical structure was more suitable. In summary, the integrate analysis showed that it was the most appropriate treatment to gain the most stable yield, economic values and quality grade structure in Yangxian’s flue-cured tobacco of Shaanxi Province that to the lower 4 pieces of unsuitable tobacco leaves decreased and the upper 1st piece of top leaf uncured.
