评价配方打叶均匀性特征值的对比分析

Comparative Analysis of Characteristic Value in Formulation Threshing Uniformity Evaluation

为了选择合适的特征值,评价配方打叶混合均匀性,对比分析了配方打叶后烟叶的烟碱、糖碱比、糖氮比和糖碱比×糖氮比变异系数与不同混合均匀梯度的符合性。结果表明:相同产地、相近等级配方打叶后,糖碱比×糖氮比变异系数可有效表达混合均匀程度,而烟碱变异系数与达混合均匀程度符合性较低。

In order to select the appropriate value characteristics,evaluation of formulation threshing mixing uniformity,comparative analysis the compliance between CV of sugar/nicotine,sugar/nitrogen sugar/nicotine×sugar/nitrogen by formulation threshing and different degree of mixing.The results showed that:CV of sugar/nicotine×sugar/nitrogen In the same origin,similar levels tobacco by formulation threshing can effectively express the uniformity of mixing,the compliance was low between mixing degree and CV of nicotine.
