在大田生产条件下 ,采用单株挂牌设置处理的方法 ,研究了环剥措施对烤烟叶片钾含量的影响。结果表明 ,在圆顶期沿茎基部环剥韧皮部 5cm左右 ,无论是烟叶的相对钾含量还是绝对钾含量 ,环剥株最终都高于未环剥的对照株。说明环剥有利于烟叶钾含量的提高 ,且影响程度存在品种间的差异。
Under the conditions of field production, the method of single set listing was used to study the effect of the circumrotation on potassium content in flue-cured tobacco leaves. The results showed that about 5 cm of the phloem around the base of the scion during the dome stage, both the relative potassium content and the absolute potassium content of tobacco leaves were higher than those of the uncoated control. The results showed that girdling was beneficial to the increase of potassium content in tobacco leaves, and the degree of influence was different among cultivars.
