以云南曲靖烟区5种不同土壤类型土样及其对应的烟样为材料，分析了土壤钾素和烤烟烟叶钾素含量在不同土壤类型中的分布特点及其相互关系。结果表明：（1）土壤钾素含量与烤烟烟叶钾素含量在5种土壤类型中存在显著差异，不同土壤类型中平均全钾含量高低顺序为紫色土＞黄壤＞水稻土＞新积土＞红壤；速效钾含量高低顺序为：黄壤＞新积土＞水稻土＞紫色土＞红壤；平均烤烟钾含量在不同土壤类型中的分布高低顺序为：黄壤＞新积土＞红壤＞水稻土＞紫色土。（2）烟叶钾素仅在红壤类型上与土壤全钾含量呈极显著正相关，仅在红壤、新积土和紫色土类型上与土壤速效钾呈极显著正相关，在其他土壤类型下烟叶...

According to 5 types of soil samples and corresponding flue -cured tobacco leaf samples in Qujing tobacco -growing area of Yunnan province , we analyzed the distributive characteristics of potassium content in both soil and tobacco leaf as well as their mutual relationship.The results showed that：（1） There were significant differences in the contents of potassium in soil and flue-cured tobacco leaves among 5 different soil types .The average total potassium content in different types of soil was ranked as follows：purple soil 〉yellow soil 〉...
