摘　　要：为了了解火山区域腾冲地区植烟土壤养分状况,2010～2011年在腾冲6个主要基地单元采集土样353个,进行了土壤养分测试分析。结果表明:腾冲地区土壤pH值均小于7,呈酸性,且大多数样品pH值处于适宜值范围内,有机质、碱解氮、速效磷含量较高,缺镁缺硼现象明显。并针对腾冲地区现状提出了稳氮、稳磷,增施镁肥硼肥,对部分土壤补施钾、锌肥的建议。In order to know the nutrient status of tobacco planted soil in volcanic region of Tengchong, 353 soil samples were collected from six main base units of Tengchong from 2010 to 2011 to test and analyze the soil nutrient. The resuhs showed that the pH of soil in Tengchong was acidic, but most of the pH was in a range of appropriate value. The contents of organic matter, available N and available P were higher than average, but the contents of effective M and B were low. Therefore, some advices were proposed according to the status quo of Tengchong, such as controlling the contents of N and P, increasing contents of M and B, partially increasing the contents of K and Zn.
