摘　　要：对盐源烟草种植区362个土样磷素钾素含量进行了分析。结果表明:盐源烟草种植区土壤有效磷、全磷平均含量分别为11.00 mg/kg和0.52 g/kg;速效钾、全钾含量平均为153.94 mg/kg和7.93 g/kg。从主要植烟土壤类型看,有效磷含量排序为:紫色土>新积土>红壤>黄棕壤>水稻土。速效钾含量排序为:为紫色土>红壤>黄棕壤>新积土>水稻土。从不同海拔高度植烟土壤来看,磷素和钾素变化规律不明显。The potassium and phosphorus contents of 362 soil samples collected from tobacco growing areas in Yanyuan of Sichuan were ana- lyzed. The results showed that the average content of available phosphorus （AP） and total phosphorus （TP） were 11.00 and 0.52 g/kg, re- spectively, the average content of available potassium （AK） and total potassium （TK） were 153.94 and 7.93 g/kg, respectively. The ma- jor types of tobacco soils in order of content of available potassium （AK） were purple soil 〉 red clay 〉 yelIow-brown soil 〉 alluvial soil 〉 paddy soil and in order of available phosphorus （AP） were purple soil 〉 alluvial soil 〉 red clay 〉 yellow-brown soil 〉 paddy soil The changes of potassium and phosphorus were not obvious in different altitudes.
