灰色关联分析方法在烟草内在质量评价上的应用

Application of Grey Incidence Analysis in the Evaluation of the Inner Quality of Tobacco

应用灰色关联分析的原理,分析了烟草内在质量与综合评分之间的关联度,结果表明:烟草主要内在质量与综合评分之间的关联度依次为糖差>总糖含量>还原糖含量>氮碱比>蛋白质含量>糖碱比>总氮含量>K2O含量>烟碱含量,为云南优质烤烟质量标准体系建立提供了重要的理论依据。

Grey incidence analysis is an analytical tool based on grey theory. The basic ideology is to estimate the relation of factors. According to this theory, through the relation index（k） and relation R, the degree of incidence between the integral rating and the inner quality of tobacco was analyzed.The results indicated that the order of relational grades of main qualitative characters was different： sugar 〉 total sugar 〉 reductive sugar 〉 the ratio of nitrogen and nicotine 〉 protein 〉 the ratio of sugar and nicotine 〉 total nitrogen 〉 K2O 〉 nicotine. The rosults provided theoretical base of the design of the standard quality system in Yunnan Tobacco.
