摘　　要：对宝鸡烟叶主产区207个土壤样品的主要养分进行了分析,结果表明:有机质含量平均为13.68 g/kg,总体上处于适宜水平;全氮、碱解氮、全磷、全钾和速效钾总体上处于适宜或较高水平;速效磷相对缺乏,96.6%的植烟土壤缺磷;土壤养分含量之间均呈极显著正相关。此外,针对土壤养分含量情况,提出了一些相应的改良措施。The author analyzed the main nutrients of 207 soil samples from major tobacco - planting counties in Baoji. The results indicated that the average organic matter content in the soil was 13.68 g/kg, which was at an appropriate level as a whole. The total nitrogen, available nitrogen, total phosphorus, total potassium and available potassium contents were generally at a suitable or higher level. The available phosphorus was relatively deficient, and 96.6% of soil samples was of phosphorus deficiency. There were ex- tremely significantly positive correlations among soil nutrient contents. Moreover, this article presented some corresponding improve- ment measures according to the status of soil fertility.
