1、重庆酉阳植烟土壤理化性状与烟叶化学成分的相关性分析王勇(重庆市烟草公司，重庆400023)摘要：采用相关分析、典型相关分析研究了湖南中烟重庆酉阳苍岭基地植烟土壤理化性状对烟叶化学成分的影响。烟区植烟土壤pH值总体适宜，速效磷相对缺乏，速效钾、碱解氮、有机质含量中等，水溶性氯含量较低，相关分析结果表明：土壤pH值与烟叶还原性糖含量正相关，与烟叶总氮含量负相关；土壤速效磷含量与烟叶烟碱含量负相关；土壤速效磷、碱解氮含量与烟叶氮碱比显著正相关。典型相关分析结果表明：烟区土壤理化性状对烟叶化学成分作用的大小依次为：pH值>速效磷>有机质>速效钾>碱解氮>水溶性氯；土壤速效钾、有机质的含量主要影响烟叶

2、中糖组分含量，土壤速效钾含量对烟叶还原糖的积累有利，对总糖积累不利；土壤有机质含量对糖含量的影响与土壤速效钾含量相反。关键词：土壤理化性状；烟叶化学成分；相关分析；典型相关；酉阳中图分类号：S158．3文献标识码：A文章编号：1006—060X(2014)O1—0043—03AnalysisofCorrelationbetweenPhysiochemiealCharacteristicsofTobaccoPlantingSoilandChemicalCompositionsofTobaccoLeafinYouyangCountyofChongqingProvinceWANGYong(Chon
