基于指数和法的皖南烤烟主要化学成分协调性分析

Coordination Analysis of Main Chemical Components of Flue-cured Tobacco in South Anhui Based on Index Sum Method

为明确皖南不同乡镇烤烟主要化学成分协调性情况,利用随机取样的方法采集10个乡镇的304份烤烟样品,采取指数和法对主要化学成分进行赋值,并进行差异性分析、简单相关分析和系统聚类。结果表明,皖南烟区烤烟常规化学成分之间有明显的差异,在10个乡镇中以寒亭、文昌化学成分得分较高;基于烤烟C3F常规化学成分综合得分的聚类分析表明,除誓节外,皖南烟区总体质量较好,差异均未达到显著水平;基于烤烟B2F常规化学成分综合得分的聚类分析分为3类,第1梯队为寒亭、洪林、文昌,第2梯队为红杨、十字、沈村、黄渡、杨柳、弋江,第3梯队为誓节。

The aim was to clarify the coordination of main chemical components of flue-cured tobacco in different towns of Anhui Province.A total of 304 flue-cured tobacco samples from 10 townships were collected by random sampling method.The main chemical components were assigned by index sum method,and differential analysis,simple correlation analysis and system clustering were performed.The results showed that,there were significant differences between the chemical compositions of flue-cured tobacco in South Anhui tobacco-growing area,the scores of the chemical compositions of Hanting and Wenchang were higher in 10 townships;the cluster analysis based on the scores of chemical compositions of flue-cured tobacco C3F showed that Shijie was In addition,the overall quality of South Anhui tobacco area was good,and the difference had not reached a significant level;the cluster analysis based on the scores of chemical compositions of flue-cured tobacco B2F was divided into three categories,the first echelon was Hanting,Honglin and Wenchang,and the second echelon was Hongyang,Shizi,Shencun,Huangdu,Yangliu,Yijiang,the third echelon was Shijie.
