本校为第一机构

对云南省曲靖烟区2005～2007年9县（市、区）所产烤烟烟叶C3F的常规化学指标进行总体描述、产烟县（市、区）、年份间、不同品种间的统计分析及烤烟各化学指标间的相关性分析,结果表明：（1）曲靖烟区烤烟中除总糖、还原糖、糖碱比略偏高,钾的含量略偏低外;总氮、烟碱、氯含量、氮碱比、钾氯比等化学指标均符合优质烟叶的要求。（2）除烟碱、氯、钾含量变异较大外,其他化学成分都比较稳定。（3）化学成分在县际间（除氯外）、年份间（除氯、钾外）、主栽品种间（除还原糖、钾外）差异不显著。（4）总糖与还原糖呈高度正相关;烟碱与总氮,氮碱比与糖碱比呈中度正相关;总氮、烟碱与糖碱比,烟碱与氮...

The comparative and correlation analysis of routine chemical indices of C3F flue-cured tobacco leaves from nine counties of Qujin from 2005 to 2007 was carried out. The results indicated that： （ 1 ） except that total sugar, reducing sugar and the ratio of total sugar to nicotine were higher, potassium was lower, total nitrogen, nicotine, chlorine contents, the ratio of total nitrogen to nicotine, potassium to chlorine and other chemical indices were correspond with the requirement of high quality fluecured tobacco. （2） except that the diff...
