摘要
采用典型相关分析方法考察了凉山烟区烤烟的主要化学指标与土壤养分之间的关系。分析结果表明:烤烟糖类化合物与土壤养分之间、含氮化合物与土壤养分之间、无机物质与土壤养分之间均有1对典型相关系数达到5%显著水平。由各组变量之间的典型变量构成的相关系数可知:烟叶的总糖、还原糖含量与土壤的全氮、碱解氮、水溶性氯的含量呈显著负相关;烟叶的挥发性碱含量与土壤中速效钾含量呈显著负相关;烟叶的硫酸根含量与土壤中有效硫含量呈显著正相关。
Canonical correlation analysis was conducted to investigate the relationships between main chemical components of flue-cured tobacco leaves and soil nutrients in Liangshan tobacco growing area of Sichuan province.The results showed that the canonical correlation coefficients between soil nutrient and sugar compound content in tobacco leaves,between soil nutrient and nitrogen-containing compound content in tobacco leaves,between soil nutrient and inorganic matter content in tobacco leaves all achieved 5% sig...
