泸州烤烟单叶重调查分析

Investigation and Analysis of Single Leaf Weight of Flue-cured Tobacco in Luzhou City

在烘烤工场对上、中、下3个部位的烟叶,以及在8个收购站点对X2F、X3F、C2F、C3F、C3L、C4F、B2F、B3F等8个收购等级的烟叶单叶重进行调查。结果表明,泸州烤烟下部、中部、上部烟叶的单叶重分别为7.00~9.00、11.01~13.00、12.00~14.00 g。下部叶X2F、X3F 2个等级烟叶的单叶重平均值为8.65 g,中部烟叶C2F、C3F、C3L、C4F 4个等级烟叶的单叶重平均值为11.85 g,上部叶B2F、B3F 2个等级烟叶的单叶重平均值为9.39 g。综上所述,泸州烤烟单叶重基本适宜,但上部烟叶单叶重略低,应采取平衡施肥、合理密植、适时打顶、科学留叶等农艺措施加以调控。

The single leaf weight of tobacco leaves in the upper, middle and lower parts in the curing workshop were investigated as well as the eight purchasing grades of X2F, X3f, C2F, C3F, C3L, C4F, B2F and B3F at the eight purchasing sites. The results showed that the single leaf weight of lower, middle and upper leaves of flue-cured tobacco in Luzhou was 7.00-9.00 g, 11.01-13.00 g, 12.00-14.00 g, respectively. The average single leaf weight of lower leaves with X2F and X3F was 8.65 g, the average single leaf weight of middle leaves with C2F, C3F, C3L and C4F was 11.85 g, and the average single leaf weight of upper leaves with B2F and B3F was 9.39 g. In conclusion, the single leaf weight of Luzhou flue-cured tobacc was basically suitable, but the single leaf weight of the upper tobacco was slightly lower, which should be regulated by adopting agricultural measures such as balanced fertilization, rational dense planting, timely topping and scientific leaf number.
