不同烤烟品种特性的综合评价研究

Comprehensive Evaluation on Characteristic of Different Variety of Flue-cured Tobacco

采用熵权法确定测定指标的权重,应用灰色系统关联度法对17个烤烟品种特性进行综合评价,结果表明,烤烟品种特性综合表现较好的为南江3号、贵烟2号、毕纳1号和遵烟6号,表现最差的为黔西1号,其余常规品种表现一般。同时利用综合评价值与各指标进行逐步回归分析,表明烤烟品种的留叶数、最大叶宽、上部叶总糖含量、下部叶氯含量、上部叶香气量、中部叶香气质、中部叶香气量和中部叶杂气8个指标对品种特性综合评价影响显著。

Entropy weight method was used to construct index weights of evaluating index, comprehensive evaluation was carried out on the seventeenth flue-cured tobaccl varieties by using gray correlative degree. The results indicated that Nanjiang 3 ,Guiyan 2,Bina 1 and Zunyan 6 were the best,the comprehensive performance of rest conventional varieties were performance general,and that of Qianxi 1 was the worst.The relationahip between comprehensive evaluation and evaluating index was analyzed with the method of stepwise regression,comprehensive evaluation of flue-cured tobacco had a significant correlation with the leaves number,width of middle leaves ,total sugar of upper leaves ,the chlorine content of lower leaves ,the sensory quality of upper leaves, smoking quantity of middle leaves and offensive odor.
