基于指数和法的皖南烤烟主要化学成分协调性分析
|
摘要
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 differenttowns of Anhui Province.A total of 304 flue-cured tobacco samples from 10 townships were collected by random sam-pling method.The main chemical components were assigned by index sum method,and differential analysis,simplecorrelation analysis and system clustering were performed.The results showed that,there were significant differencesbetween the chemical compositions of flue-cured tobacco in South Anhui tobacco-growing area,the scores of thechemical compositions of Hanting and Wenchang were higher in 10 townships;the cluster analysis based on thescores of chemical compositions of flue-cured tobacco C3F showed that Shijie was In addition,the overall quality ofSouth Anhui tobacco area was good,and the difference had not reached a significant level;the cluster analysis basedon the scores of chemical compositions of flue-cured tobacco B2F was divided into three categories,the first echelonwas Hanting,Honglin and Wenchang,and the second echelon was Hongyang,Shizi,Shencun,Huangdu,Yangliu,Yijiang,the third echelon was Shijie.
