烟叶模块烟碱变异系数与几个因子的相关性分析

摘要

[目的]探讨烟叶模块烟碱变异系数与烟叶模块数量、烟叶模块部位、烟叶模块等级个数的关系.[方法]对2015年贵州中烟加工烟叶模块烟碱变异系数与烟叶模块数量、烟叶模块部位、烟叶模块等级个数进行相关性分析和数理统计.[结果]烟叶模块烟碱变异系数与烟叶模块数量呈极显著正相关,烟叶模块烟碱变异系数与烟叶模块部位和烟叶模块等级个数相关性不明显;数量级在2.5×105kg以下的烟叶模块平均烟碱变异系数较小,数量级在7.5×105~1.5×106kg的烟叶模块平均烟碱变异系数较大;从变化趋势看,烟叶模块数量级越大,平均烟碱变异系数也越大;上部上等烟叶平均烟碱变异系数最小,中部中等烟叶平均烟碱变异系数最大;烟叶模块平均烟碱变异系数从高到低依次是中部中等烟叶、下低等烟叶、上部中等烟叶、下部中等烟叶、中部上等烟叶、上部上等烟叶.[结论]该研究可为片烟均值化加工提供理论依据.%[Objective] The aim was to discuss the relationship between tobacco module nicotine variation coefficient and tobacco module number,tobacco module position and tobacco module rank number.[Method] Correlation analysis and mathematical statistics of tobacco module nicotine variation coefficients and tobacco module number,tobacco module position and tobacco module rank number from China Tobacco Guizhou Industrial Co.,Ltd.,in 2015 was conducted.[Result] The results showed that tobacco module nicotine variation coefficients and tobacco module number are extremely positively correlated,there is no obvious correlationship between tobacco module nicotine variation coefficients and tobacco module position,tobacco module rank number;The average nicotine variation coefficient of tobacco modules with orders of magnitude below 2.5×105 kg was smaller,the orders of magnitude between 7.5×105 and 1.5×106 kg tobacco modules had more average nicotine variation coefficient.From the change tend,the larger the number of tobacco modules,the average nicotine variation coefficient is greater.The average nicotine variation coefficient of the superior class top tobacco leaves was minimal,the average nicotine variation coefficient of the medium class middle part tobacco leaves was maximal.The average coefficient of variation of tobacco module nicotine from high to low is the medium class middle part tobacco leaves,low class bottom tobacco leaves,medium class upper part tobacco leaves,medium class bottom tobacco leaves,superior class middle part tobacco leaves,superior class upper part tobacco leaves.[Conclusion] The study can provide theoretical basis for tobacco homogenization process.
