摘要
运用灰色关联分析方法对文山州气象因子中的月平均温度和降水量与烟叶主要化学成分进行关联分析,结果表明,月平均温度对主要化学成分的影响明显大于降水量。B2F烟叶主要化学成分受月平均温度的影响大小依次为烟碱>总氮>总糖>还原糖>钾>氯,C3F烟叶主要化学成分受月平均温度的影响大小依次为烟碱>总氮>还原糖>总糖>钾>氯,X2F烟叶主要化学成分受月平均温度的影响大小依次为烟碱>钾>总氮>还原糖>总糖>氯。
The gray correlation analysis between monthly rainfall and mean temperature in Wenshan and the contents of chemical compositions in flue -cured tobacco were analyzed.The results indicated that effects of monthly mean tempera-ture on main chemical compositions were significantly higher than those of monthly rainfall.Effects of monthly mean tem-perature on main chemical composition of B2F flue -cured tobacco leaves showed the trend of nicotine >total N >total sugar >reducing sugar > potassium > chlorine.Effects of monthly mean temperature on main chemical composition of C3F flue -cured tobacco leaves showed the trend of nicotine >total N > reducing sugar > total sugar > potassium >chlorine.Effects of monthly mean temperature on main chemical composition of X2F flue -cured tobacco leaves showed the trend of nicotine >potassium >total N >reducing sugar >total sugar >chlorine.
