| 摘 要： | 目的]探讨十堰烤烟化学成分的稳定性和年度变化趋势。方法]对十堰2010—2016年烤烟3个部位(B2F,C3F,X2F)烟叶的主要化学成分进行测定和方差分析。结果]十堰烟叶主要化学成分均存在不同程度变异。氯的变异系数最大为66.43%,较不稳定;总糖的变异系数最小为11.15%,比较稳定。十堰烟叶的烟碱、总氮、氯年度间差异均不显著,总糖和钾年度间的差异显著。烟叶的烟碱、总氮、钾部位间差异不显著,总糖和氯部位间差异显著。十堰烤烟总氮、烟碱、钾含量相对适宜,氯含量相对偏低,总糖含量相对较高。结论]进一步协调烟叶糖碱比、钾氯比是十堰烟区下一步提升烟叶内在品质的主攻方向。

Analysis of the Variation of the Main Chemical Components of Flue-cured Tobacco in the Different Years——Taking Shiyan Tobacco Area as an Exapmle |

| Abstract: | Objective]To analyze the stability and annual variation tendency of chemical components of flue-cured tobacco in Shiyan Area.Method] Main chemical components of 3 grades(B2F,C3F,X2F) tobacco during 2010-2016 from Shiyan Area were determined and analyzed by using analysis of variance.Result] There were differences in main chemical components of Shiyan tobacco.The variation coefficient of chlorine (66.43 ％) was the largest,the smallest variation coefficient was 11.15 ％ of total sugar.The differences of nicotine,total nitrogen and chlorine among years were not significant,but the differences of total sugar and potassium were significant.The differences of nicotine,total nitrogen and potassium among grades were not significant,but the differences of total sugar and chlorine were significant.The flue-cured tobacco total nitrogen,nicotine,potassium content were relatively appropriate,but the chlorine content was relatively low,total sugar content was relatively high in Shiyan area.Conclusion] Further coordination of tobacco leaf sugar alkali ratio,potassium chloride ratio is the main direction to improve the internal quality of tobacco leaf in Shiyan Area. |
