摘要[目的] 为研究昭通市各烟区的土壤养分情况。[方法] 在2011～2013年，对昭通市昭阳区、巧家县、彝良县、镇雄县、永善县、大关县、威信县、鲁甸县8个县区土壤进行调查分析。[结果] 昭通市绝大部分植烟土壤的pH适宜烤烟生长。有机质含量丰富，全氮含量丰富，土壤供氮能力强，水解氮含量总体满足烤烟生长。全磷和全钾含量较低，速效磷和速效钾含量处于中低水平。33.46%的植烟土壤氯离子含量低于30 mg/kg。[结论]昭通市大部分植烟土壤能满足优质烟叶原料的生产，但宜适当增施磷钾肥。同时，对于少部分氯离子含量低于30 mg/kg的少氯土壤，应适当增加氯元素肥料的施用。 关键词昭通市；土壤养分；评价

Abstract [Objective] The research aimed to study soil nutrient contents in fluecured tobacco growing area of Zhaotong City. [Method]Tobacco growing soil samples in Zhaoyang District， Qiaoojia County， Yiliang County， Zhenxiong County， Yongshan County， Daguan County， Weixin County， Ludian County were collected and analyzed in 2011-2013. [Result] Almost all soil pH was available to the growth of fluecured tobacco in Zhaotong. The organic matter in soil was very abundant， nitrogen content was high， and the capacity of soil nitrogen supply was outstanding. And the amount of available nitrogen met the demand with fluecured tobacco growth. The levels of total phosphorus content and total potassium content were lower than the level of the whole. The level of available phosphorus and available potassium were at a low level. 33.46% chloride ion content in tobacco planting soil was less than 30 mg/kg.[Conclusion]Most tobaccoplanting soil in Zhaotong City could meet the demand of the production of sound tobacco， but it was suitable for the proper application of P and K fertilizer. As for part soil with a few chlorine which was inferior to 30mg/kg， the application amount of chlorine fertilizer should be increased. Key words Zhaotong City；Nutrient status of the soil；Evaluation
