摘要
采用水浸提烤烟叶片的方法研究了成熟期水浸提对叶片钾含量的影响。结果表明,水浸提烟叶后造成了钾含量的损失,烟叶中钾(%)的损失率从0.099%~0.2437%。同一烟株的不同叶位,对照和处理L3(施钾量157.5kg/hm^2)的钾含量损失率为顶叶>腰叶>底叶;处理L1为腰叶>底叶>顶叶;处理L2(施钾量105.0kg/hm^2)和L4(施钾量210.0kg/hm^2)则为腰叶>顶叶>底叶。
The effects of water extracting on flue-cured tobacco leaves in mature stage were studied. The results showed that potassium content in tobacco leaves decreased after water extracting. The losing rates of potassium ion were from 0.099% (priming of L2 and L4) to 0.2437% (cutters of L1) . The stalk positions in the same plant of control and treatment L3 in order of potassium-losing rate were tips > cutters > priming, of L1 treatment were cutters > priming > tips, and of treatment L2 and L4 were cutters > tips > priming.
