摘  要：
2011年,采用描述性统计、系统聚类分析等方法,对凉山烟区6种植烟土壤氮、磷、钾在土壤中分布特征及其土壤类型间的差异性进行分析,以期探明凉山烟区主要植烟土壤理化特性,为烟叶生产提供指导。结果表明,凉山烟区不同植烟土壤类型间土壤碱解氮、速效磷、速效钾含量均存在广泛的变异;土壤各层次中碱解氮含量随着土层深度的增加而降低;速效钾含量随着土层深度的增加先大幅减少再小幅增大;速效磷在不同层次间无明显规律。各土壤类型养分含量在20～40 cm土层普遍偏低,烟叶生产中应高起垄深移栽,培植绿肥深耕翻掩,提高土壤熟化程度,为烟叶生长发育提供良好的肥力基础。

摘  要：
To definite the physical and chemical properties for Liangshan major tobacco soil types and provide a guidance for tobacco production,the method of descriptive statistics and systematic cluster analysis were used to analyze the content of available nitrogen,phosphorus and potassium at each layers of soil profile and the differences between soil types in 6 tobacco planting soil of Liangshan tobacco area in 2011.The results showed that: the content of available nitrogen,phosphorus and potassium were widely variant for all soil types in Liangshan tobacco area.The content of available nitrogen reduced as the increasing of soil depth in soil profile.However,available potassium content first greatly reduced and later slightly increased.There was no obvious regularity in the profile between different layers for available phosphorus.Nutrient content of different soil types was generally low in 20-40 cm soil layer.Deep transplantation,high ridges green manure planting and deep inplough were recommended to 20-24 cm soil layer improvement to provide quality soil fertility basis for tobacco growth.
