摘　　要：[目的]分析腾冲县火山灰母质不同类型植烟土壤养分状况。[方法]对云南省保山市腾冲县烟区火山灰母质的旱地与水田土壤样品各81个进行了土壤养分的测定及比较。[结果]腾冲县烟区火山灰植烟土壤整体偏酸,旱地土壤的pH平均值低于水田。腾冲烟区火山灰母质植烟土壤的有机质和碱解N含量整体偏高;水田土壤的速效K含量偏低,而旱地土壤速效K含量较丰富,其有效Mg含量则偏低;腾冲烟区有效Zn、有效B和水溶性Cl含量整体偏低。[结论]为腾冲县烟区的土壤改良与平衡施肥提供了参考。[ Objective ] The aim was to analyze the nutrient status of different kinds of volcanic ash tobacco-growing soils in Tengchong. [ Meth- od] Nutrient status of 81 dry-land soil samples and 81 paddy field soil samples from tobacco-growing areas in Tengchong County of Yunnan Prov- ince were analyzed and compared. [ Result ] The soils in Tengchong were of slight acid. The average pH of dry-land soil was lower than that of paddy field soil. Contents of organic matter and alkaline N in Tengchong were too higher, while contents of available Zn, available B and water sol- uble C1 were in low level. The content of available K in paddy field soil was in a low level ,while dry-land soil was rich in available K. The content of available Mg in dry-land soil was in a low level. [ Conclusion] The research provides reference for soil improvement and balanced fertilization of tobacco in Tengchong.
