采用典型相关分析方法研究了土壤理化性状与烟叶主要化学成分含量的关系。结果表明:土壤速效钾和有效镁含量与烤后上部和中部烟叶中钾、总糖和氯含量关系密切,在一定范围内,土壤有效镁含量与上部和中部烟叶中钾、总糖和氯含量呈显著负相关,土壤速效钾含量与上部和中部烟叶中钾、总糖和氯含量呈显著正相关;在一定范围内,土壤pH值与中部烟叶中总糖、氯以及钾含量呈显著负相关。
Canonical correlation analysis was used to study the relationship between soil physical and chemical properties and the main chemical components of tobacco leaves. The results showed that the contents of available potassium and available magnesium in soil were closely related to the contents of potassium, total sugar and chlorine in the upper and middle tobacco leaves. Within a certain range, the content of soil available magnesium was positively correlated with the contents of potassium, total sugar and chlorine in the upper and middle leaves There was a significant negative correlation between soil available potassium and potassium, total sugar and chlorine content in upper and middle tobacco leaves. Within a certain range, soil pH value had a significant negative correlation with total sugar, chloride and potassium content in middle tobacco .
