土壤类型对土壤钾素与烤烟烟叶钾素分布及其相互关系的影响研究--以云南省曲靖市为例
Studies on Influences of Soil Type on Distribution of Potassium in both Soil and Flue-cured Tobacco Leaf as well as Their Mutual Relationship in Qujing City, Yunnan Province
摘要
Abstract
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 .关键词
