摘　　要：为探究云南陆良烟区土壤肥力状况,对该县境内的植烟土壤进行了系统的调查取样,并利用灰色关联度分析法对该地区不同植烟土壤类型的土壤肥力状况进行了综合评价及关联度分析。结果表明:1陆良县植烟土壤类型主要有水稻土、红壤、新积土和紫色土,其中以红壤和水稻土为主。2新积土氮、磷、速效钾和有效镁含量较高;红壤有效钼含量较高,全钾和速效磷含量较低;水稻土p H相对较高,速效钾含量较低;紫色土p H及氮、磷含量偏低,全钾和有效硼含量较高;4类土壤的有效硫和水溶性氯含量均不同程度偏高。34类植烟土壤肥力的灰色关联度排序为:红壤(0.8548)>新积土(0.8392)>水稻土(0.8222)>紫色土(0.8214),说明在该区的生态环境条件下,红壤的肥力较高,紫色土的肥力最差,且土壤肥力与土壤颗粒构成存在一定的相关性。In order to study the fertility of tobacco planting soil in Luliang county,Yunnan province,soil samples were collected systematically from local tobacco planting area,and the relationships between soil types and fertility by grey relation analysis were studied. The results showed that（i） Red soil and paddy soil are major soil types in local.（ii） Alluvial soil was rich in N,P,available K and available Mg; The contents of K and available P of red soil were low while available Mo was rich; The p H of paddy soil was high comparatively while available K was low; The K,P and p H of purple soil were a lot low,however,available K and available B were high. In addition,the available S and available Cl of 4 soil types were on the high side.（iii） Soil fertilities of 4 types of tobacco planting soil varied significantly,which were in order of red soil（0. 8548） alluvial soil（0. 8392） paddy soil（0. 8222） purple soil（0. 8214）. It indicated that red soil was more fertilizer than any other soil types,while purple soil had the poorest fertility. Moreover,soil fertility was not only related to nutrition content but also to particles distribution.
