摘要： 为探讨凤凰县烤烟化学成分的稳定性和年度变化趋势，以凤凰县7年的B2F、C3F、X2F 3个等级烟叶为试验材料，采用方差分析和回归分析方法对其化学成分年度变化规律进行研究。结果表明：（1）凤凰县烟叶钾和氯的年度稳定性最差，总氮稳定性最好；（2）除B2F等级的总糖和还原糖外，不同年份间烟叶化学成分差异达极显著水平；（3）烟叶总糖、还原糖年度间变化呈升高趋势；烟碱、总氮、钾、氯年度间变化呈下降趋势。

Abstract: The laws of annual changes on chemical components of flue-cured tobacco with 3 grades (B2F,C3F,X2F) from Fenghuang County in 7 years were studied by the way of variance analysis and regressive analysis in order to explore their stability and variation tendency. The results showed that the stability of potassium and chlorine were worst, while that of total nitrogen was best in different years. The differences of chemical components of flue-cured tobacco among years were significant at 1% level, except that total sugar and reducing sugar of B2F grade. The variation tendency of total sugar and reducing sugar increased, while that total nitrogen, nicotine, potassium and chlorine decreased in different years.
