摘　　要：在云南丽江烟区采集273个土壤样品和烟叶样品进行分析化验。结果表明,丽江市植烟土壤中微量营养元素含量存在较大的差异,土壤平均交换性钙含量为3338.82 mg kg-1,交换性镁342.26 mg kg-1,有效锌2.21 mg kg-1,有效硼0.54 mg kg-1,有效钼0.44 mg kg-1,水溶性氯38.37 mg kg-1。植烟土壤交换性钙、交换性镁和有效钼含量整体比较充足,有效锌含量整体适宜,有效硼含量普遍缺乏;尽管土壤中水溶性氯含量较高,但烟叶中氯含量较低。为此生产上提出了"控镁和补硼"的施肥措施,对于连年干旱且水溶性氯含量高的植烟土壤要严禁施用含氯肥料。Soil and tobacco leaf samples were taken in Lijiang tobacco-growing region. Results indicate that content of soil nutrients showed significant variation at different locations. The average contents were as follows: exchangeable Ca3338.82 mg kg-1, exchangeable Mg 342.26 mg kg-1, available Zn 2.21 mg kg-1, available B 0.54 mg kg-1, available Mo0.44 mg kg-1, and water soluble chloride 38.37 mg kg-1. It was found that soil water soluble chloride was high but the chloride content in leaf was low. Hence, controlling Mg and supplying B should be the tobacco fertilition strategy in Lijiang.
