文山烟叶主要化学成分与土壤养分典型相关分析
摘 要：采用典型相关分析方法研究了云南文山烤烟化学成分与土壤养分状况之间的关系，结果表明：土壤pH值与烟叶还原糖呈显著或极显著正相关，土壤速效钾含量与钾和钾氯比呈显著或极显著正相关，土壤有效镁与烟叶还原糖呈极显著负相关。土壤有机质、速效磷、有效镁和水溶性氯含量对B2F和C3F烟叶主要化学成分的影响存在一定差异。土壤养分对B2F烟叶烟碱含量和糖碱比的影响大于C3F，土壤养分对C3F烟叶钾含量的影响大于B2F。

Abstract：The correlations between the contents of chemical components of flue-cured tobacco and soil nutrients in Wenshan were analyzed with canonical correlation analysis. The results indicated that there were significant or extremely significant positive correlation between the reducing sugar content of tobacco leaves and soil pH value， as well as between soil available potassium content and the ratio of potassium to chlorine； soil effective magnesium content was extremely significantly negative correlated with the reducing sugar content of tobacco leaves. There ...
