烤烟主要化学成分的因子分析

对我国优质烤烟产区云南省的烤烟主要化学成分进行因子分析。化学成分相关系数矩阵表明 ,烤烟多种化学成分间存在显著或极显著的相关性 ,相关系数矩阵前 4个特征根的累计贡献率已达 85 .3 8%。由化学成分的因子载荷矩阵得到 4个主因子 ,即碳氮因子、灰分因子、氯因子、烟叶pH值因子

Analysis of the Main Chemical Components of the Flue-cured

The analysis of the main chemical components of Yunnan flue-cured tobacco was carried out in the paper. The coefficient correlation matrix of chemical components showed that there was significant or extremely significant correlation among the main chemical components. The contribution rate of first-four characteristic roots was 85.38%.Four main factors from the factor load matrix, namely the carbon nitrogen factor, ash content factor, factor of pH value of tobacco leaf and chlorine factor.
