三门峡烟区烤烟质量可用性综合评价

选取2004~2006年三门峡烟区126份烤烟样品,对样品的9项化学指标进行了分析测试,并应用灰色关联分析法对烟叶质量可用性指数(tobacco quality usability index)进行评价。结果表明:该区40%的烟叶样品糖含量和糖碱比值明显偏高,其余化学成分含量和比例基本协调,烤烟质量可用性(TQU)以陕县和卢氏为最佳,部位间表现为上部叶大于中下部叶,年际间烤烟可用性基本稳定;烟叶质量的加权关联度处于0.3~0.9之间,烟叶质量可用性(TQU)属于中级和较高级。

Comprehensive Evaluation on Tobacco Quality Usability in Sanmenxia Tobacco-growing Areas

This paper collected 126 flue-cured tobacco samples produced in 2004-2006 in Sanmen-xia tobacco-growing areas.Nine chemical indexes of the samples were analyzed and the tobacco quality usability index(TQUI) was evaluated using grey correlative analysis method.The results indicated that the sugar content and RS/Nic.of 40% samples were obviously higher and the rest samples were appropriate.The TQU of samples from Shanxian county and Lushi county was the best.The TQUI of leaves is larger than cutters and lugs among different position groups.The TQU of flue-cured tobacco is steady among different years.The weighted correlative degree of tobacco quality located in 0.3-0.9,and TQUI belonged to medium and higher grade.
