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钾素与土壤钾素相关性不明显。在将土壤钾素含量分组后，在红壤中，烟叶钾含量随土壤全钾和速效钾含量的变化而表现出了较大的差异；在黄壤和水稻土中，烟叶钾含量在不同土壤钾素分组间未表现出明显的差异性；在新积土和水稻土中，烟叶钾含量在土壤全钾含量分组中没有明显的差异性，但在土壤速效钾含量的分组中则表现出较大的差异性。

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 >paddy soil >alluvial soil >red soil.The average available potassium content was ranked as follows:yellow soil >alluvial soil >paddy soil >purple soil >red soil.The average potassium content in flue -cured tobacco leaves in different soil -type fields had the following order:yellow soil >alluvial soil >red soil >paddy soil >purple soil.(2) Potassium content in tobacco leaves was very significantly correlated with soil total potassium content only in red -soil field, and was very significantly correlated with soil available potassium content only in red -soil, alluvial-soil and purple-soil fields, but it was not significantly correlated with soil potassium content in other soil -type fields.After the grouping of soil potassium content , the content of potassium in tobacco leaves varied largely with the changes in soil total potassium and available potassium contents in red-soil field;the content of potassium in tobacco leaves varied unobviously with the changes in soil potassium content in yellow -soil and paddy-soil fields;in alluvial-soil and paddy-soil fields, there was no significant difference in tobacco leaf potassium content among different soil total potassium content groups , but there was a large difference in tobacco leaf potassium content among different soil available potassium content groups .
