[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 research aimed to analyze the nutrient status of different types of tobacco soil in volcanic ash in Tengchong County. [Method] The soil nutrients of 81 soil samples of dry land and paddy soil from volcanic ash parental material in Tengchong County of Baoshan City, Yunnan Province were measured and compared. [Result] The soil of volcanic ash tobacco planting area in Tengchong County was slightly acidic, while the average soil pH of dry land was lower than that of paddy field. The contents of organic matter and alkaline hydrolysis N in volcanic ash parent soil of Tengchong tobacco area were generally high. The available K content in paddy soil was low, but available K content in dry land was more abundant, while the available Mg content was lower. , Effective B and water-soluble Cl overall low content. [Conclusion] This provided reference for soil improvement and balanced fertilization in tobacco area of ​​Tengchong County.
