摘　　要：为了解云南罗平县植烟土壤和烤烟烟叶主要中、微量元素含量情况,测定了罗平县369个土壤和对应C3F等级烟叶的钙、镁、硫、铜、锌、铁、锰和硼含量,并评价了丰缺状况,分析了两者之间的关系。结果表明,罗平土壤中钙、镁、铜、锌、铁和锰含量普遍处于丰富和很丰富的水平,而硫和硼含量相对较低,普遍处于缺和很缺的水平,罗平土壤中有效中、微量元素存在空间上的广泛变异;烤烟生产上应适当增施硼肥。烟叶中硫、铜、锌和锰含量的平均值在适中范围内,铁含量较高,钙、镁和硼含量较低。土壤中有效中、微量元素的含量对烟叶中相对应的中、微量元素有促进作用。土壤中交换性镁对烟叶多种中、微量元素有促进或抑制作用,有效铜表现出了对锌的促进作用和对硼的抑制作用。The distribution characteristics and relationships of calcium, magnesium, sulfur, copper, zinc, iron, manganese and boron in 369 samples of soils and flue-cured tobacco （C3F） collected from Luoping were investigated. The results showed that the contents of calcium, magnesium, copper, zinc, iron, and manganese were sufficient, while sulfur and boron contents were relatively insufficient. There were widely spatial variability among soil available medium and micro nutrient contents. It is suggested to apply boron fertilizer during tobacco plant growth period. The average contents of sulfur, copper, zinc and manganese were in the ranges of high quality tobacco leaf production in China, but iron content was too high and calcium, magnesium and boron contents were too low. The nutrient contents in tobacco leaves were positively correlated with the nutrient contents in soil. Soil magnesium had promoting or inhabiting effects on medium and micro nutrients in tobacco leaves. Soil copper promoted the zinc uptake but inhibited boron uptake.
