摘　　要：[Objective] The aim was to explore interannual changes of soil nutrients in tobacco soils in Zhaotong, in order to provide theoretical references for tobacco bal- anced fertilization in Zhaotong. [Method] The research analyzed nutrient changes in tobacco soils in Zhaotong during 2011-2013. [Result] In Zhaotong, pH value of to- bacco soils was increasing; the contents of organic matter and N, P and K contents were in the range suitable for tobacco growth; CI- content was growing in tobacco soils and reached the highest in 2013. [Conclusion] In general, soil nutrients show insignificant differences internannually in Zhaotong.[目的]了解昭通市植烟土壤年际间变化情况,从而为昭通市烟叶生产平衡施肥提供理论依据。[方法]对昭通市自2011-2013年间主要的烤烟种植区域土壤养分变化状况进行调查分析。[结果]昭通市植烟土壤的p H值有增大的趋势;土壤中有机质和氮磷钾的含量均基本处于适宜范围,满足烤烟生长,各年际间含量无明显变化;植烟土壤中的氯离子含量逐年上升,2013年的增幅最大,但均值未超过烤烟生长所需氯离子的范围。[结论]昭通市植烟土壤总体上养分含量年际间无明显变化。
