摘要 [目的]分析會东县烤烟各年度化学成分稳定性，为改进烟叶生产技术措施、生产稳定优质烟叶以及卷烟工业合理选择原料提供依据。[方法]选取会东县烤后烟样品，进行主要化学成分的测定，并进行方差分析。[结果]会东县烤烟主要化学成分平均值基本符合工业企业要求，两糖含量偏高，钾含量偏低。会东县烤烟B2F、C3F主要化学成分含量等级间的变化基本符合烟叶化学成分含量的部位特征。主要化学成分含量变异系数中氯、钾氯比的变异较大，其他各项指标变异均较小;其中C3F氯含量的变异系数最大，说明C3F氯含量较不稳定;C3F总糖含量的变异系数最小，说明C3F总糖含量较稳定。会东县烤烟主要化学成分变异性在各年度表现不同。C3F等级烟叶年度间变异较小，其中还原糖、氯、钾、总氮、淀粉含量各年度间均无变异，较稳定。B2F等级烟叶总糖、糖碱比有所变异，其他化学成分年度间变异较小，其中氯、钾、钾氯比较稳定。[结论]会东县烤烟化学成分年度间变化基本稳定，基本符合卷烟原料需求。

Abstract [Objective]To analyze the stability of the chemical composition of flue cured tobacco in Huidong County in each year， and provide a basis for improving the technical measures of tobacco production， producing stable and high quality tobacco and rationally selecting raw materials for the cigarette industry.[Method]A sample of flue cured tobacco from Huidong County was selected， the main chemical components were determined and the variance analysis was carried out. [Result]The average value of the main chemical components of flue cured tobacco in Huidong County basically met the requirements of industrial enterprises， the content of sugar was on the high side and the content of potassium was on the low side. The changes of the main chemical composition levels of flue cured tobacco B2F and C3F in Huidong County basically accord with the site characteristics of tobacco chemical composition content. The variation of chlorine and potassium chloride ratio in the coefficient of variation of main chemical composition content was larger，the variation of other indexes was small. The coefficient of variation of C3F chlorine content was the largest， which indicated that the C3F chlorine content was unstable， and the coefficient of variation of C3F total sugar content was the smallest， which indicated that the total sugar content was stable. The variability of main chemical components of flue cured tobacco in Huidong County was different in each year. The variation of C3F grade tobacco leaves was relatively small. Among them， the content of reducing sugar， chlorine， potassium， total nitrogen， and starch had no variation from year to year and was relatively stable.The changes in total sugar， sugar base ratio of B2F grade tobacco leaves were observed， and the variation of other chemical components was smaller from year to year. Among them， chlorine， potassium， and potassium chloride were relatively stable.[Conclusion] The chemical composition of flue cured tobacco in Huidong County is stable and meets the demand of cigarette raw materials.
