采用聚类分析方法,对山东22个植烟县169个乡镇3年共计464个烤烟初烤烟叶C3F样品的化学成分进行了分析和评价。结果表明:山东烟区烤烟化学成分的平均值基本都在优质烟的适宜值范围内,说明山东烟区各项化学成分协调,是烤烟的优质产区;用聚类分析方法将山东烟区分为5类,即中糖中碱中氯区、低糖高碱中氯区、高糖中碱中氯区、高糖低碱中氯区、高糖中碱低氯区,多元方差分析和多重比较表明,各类间差异明显。
The cluster analysis was used to analyze and evaluate the chemical constituents of 463 primary flue-cured tobacco C3F samples from 169 towns and villages in 22 Shandong Tobacco-planting counties in three years. The results showed that the average value of the chemical components of flue-cured tobacco in Shandong Province was basically within the appropriate range of good-quality tobacco, indicating that the coordination of chemical components in tobacco-growing areas in Shandong Province was the high-quality producing area for flue-cured tobacco. Using the cluster analysis method, 5 categories, namely, the sugar in the chlorine in the area of alkali, low-sugar high-alkali in the area of chlorine, high-sugar medium-alkali chloride, high-sugar low-alkali in the area of chlorine, high-sugar alkali low chlorine area, multivariate analysis of variance and multiple comparisons , All kinds of differences between the obvious.
