摘  要：
通过对曲靖烟区2006~2007年207个烤烟样品的测定分析,研究了不同产烟县、不同等级、不同品种烟叶的中微量元素含量分布特点。结果表明:曲靖烟区烤烟的中微量元素含量较为适中,绝大部分烟叶样本的镁、铁、锰、硼含量达到巴西优质烟叶的水平。从各县所产烟叶的中微量元素含量来看,罗平所产烟叶最符合巴西优质烟叶标准,马龙、麒麟、师宗、沾益所产烟叶表现次之。不同等级烟叶中钙、镁、硫、铁、硼含量差异均达到显著水平。不同品种烟叶的钙、锌含量差异显著。

摘  要：
Through analysis of 207 flue-cured tobacco samples from 2006 to 2007 in Qujing tobacco-growing areas,this paper made a study of the distribution characters of medium and trace element contents of tobacco leaves from different counties,grades and varieties.The results indicated that medium and trace element contents of tobacco leaves were moderate in Qujing tobacco-growing areas.The contents of Mg,Fe,Mn and B in most tobacco-leave samples reached the level of high-quality flue-cured tobacco leaves in Brazil.According to the contents of medium and trace elements in different counties,the tobacco leaves in Luoping were up to the standard of high-quality tobacco in Brazil,while the tobacco leaves in Malong,Qilin,Shizong and Zhanyi took second place.The difference in contents of Ca,Mg,S,Fe and B was statistically significant in different grades of tobacco leaves.The contents of Ca and Zn were obviously different in distinct varieties.
