| 摘 要： | 通过对南丹地区不同叶位的烤烟叶片进行化学成分的检测,了解不同部位叶片主要化学元素分布状况。结果表明：不同叶位镁元素的分布状况为由上到下递减,表现为中下部叶片明显缺镁,缺镁程度由上到下呈递增趋势;碱和总氮含量均未达到理想水平;总糖和还原糖含量在缺镁条件下均超出最佳值,说明烟株缺镁导致烟叶成熟度不够;钾含量逐渐降低,并都处于适宜水平,同时由于钾镁之间的拮抗作用,间接导致南丹地区烟叶中镁含量的不足。

| Abstract: | Through the chemical composition examination to the different flue-cured tobacco leaf position in Nadan area,kown the chemistry quality from different flue-cured tobacco leaf position.The result showed that the distributed condition on magnesium condition is decreasing progressively fromtop down,the performance is the middle and low position lacks the magnesium obviously,the magnesium deficienticy degree from top down to assume the increasing tendency.Nicotine and total nitrogen content do not achieve the i... |
