2、施肥提供参考依据。【方法】应用典型相关分析的方法,分析土壤中微量元素含量与烟叶品质的相关性。【结果】土壤中微量元素中有效铁、有效铜、速效硫含量分别与烟叶化学成分中的总糖、烟碱、总氮、还原糖含量典型相关,土壤样品中有效铁、有效铜和速效硫的平均含量分别为32.89、1.69和31.42mg/l【g;速效硫、交换性钙、有效锌、水溶性硼含量与香气成分中石油醚、棕色化反应产物类、西柏烷类降解产物、类胡萝卜素降解产物、新植二烯含量典型相关,样品中有效钙、有效锌和水溶性硼的平均含量分别为13.44、1.91和o.24m舭g。【结论】土壤中微量元素与烟叶化
3、学成分、致香物质之间典型相关,四川泸州植烟土壤中微量元素含量普遍处于缺乏水平,在施肥过程中应合理增加中微量元素的比例,以提高泸卅I烟区烟叶整体质量。关键词:烤烟;土壤;中微量元素;烟叶品质;相关性;泸州中图分类号:S572;S153.6l文献标志码:A文章编号:2095—1191(2012)02—0200—05Relationshipbetweensoilmoderateandmicr0nutrientsandqualityoftobaccoleafinLuzhoutobaccogrowingareaXIEQiang1,SHIShuang—
