以云烟97品种为材料,通过对比两种不同采收方式下叶绿素、外观品质及内在化学成分的差别,研究了不同采收方式对上部烟叶质量的影响。结果表明:一次性采收的上部烟叶各叶位叶绿素含量降低,上部1～6片烟叶的外观品质明显提高,主要表现在烟叶成熟度、发育状况、叶片结构、身份、油份、色度、色均匀度等方面;在内在化学品质方面,一次性采收方式采收的烟叶钾含量、总氮、烟碱含量都要低于传统采收方式采收的烟叶,而淀粉、总糖、还原糖含量都要高于传统采收方式采收的烟叶;总体上看,一次性采收方式采收的烟叶成熟度较高、外观质量较好、化学品质更协调,有利于上部烟叶质量和可用性的提高。
Taking Yunyan 97 as material, the effects of different harvesting methods on the quality of upper leaves were studied by comparing the difference of chlorophyll, appearance quality and internal chemical composition under two different harvesting methods. The results showed that the content of chlorophyll decreased at the upper leaves and the appearance quality of the upper leaves at 1 ~ 6 increased significantly, mainly in the maturity, development status, leaf structure, identity, oil, color, Color uniformity, etc. In terms of internal chemical quality, the potassium content, total nitrogen and nicotine content of tobacco collected in one-off harvesting are lower than those of the tobacco harvested by traditional harvesting methods, while the starch, total sugar, reduction The content of sugar should be higher than that of the tobacco harvested by traditional harvesting methods. Generally speaking, the tobacco harvested by one-time harvesting method had higher maturity, better appearance quality and better chemical quality, which was favorable for the quality and usability of the upper leaves Improve.
