摘要
[目的]为研究宝鸡烟区烟田土壤养分状况。[方法]取样点207个覆盖了全市3个烟区(陇县、麟游县、凤县)的植烟土壤,对宝鸡主产烟县207个土壤样品主要养分进行分析。[结果]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、全钾和速效钾含量总体上处于适宜或较高水平;速效磷含量相对缺乏;土壤养分含量之间均在0.01水平显著正相关。对23个乡镇土壤养分含量进行聚类分析,可以分为4类。根据各类土壤养分含量的平均值和标准差,制定相应的施肥方案。[结论]针对土壤养分含量情况,提出一些改良措施。
[Objective]The research aimed to study soil nutrient contents in Baoji tobacco-planting area.[Method]A total of 207 tobacco-planting soil samples were collected from three tobacco-planting areas（Longxian,Linyou and Fengxian） in Baoji.And major nutrients in tobacco-planting counties were determined.[Result]The average organic matter content 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 content in the soil were generally at a suitable or higher level.The available phosphorus was relatively deficient.The soil nutrient content had extreme positively significane.23 soil samples collected from tobacco-planting areas were analyzed with the method of cluster analysis.Comparing the mean and std.D of every cluster＇s nutrients value to the critical of soil nutrients in tobacco-planting area,the suggestions of fertilization according to 4 clusters were given.[Conclusion] Some improving measures were presented according to the status of soil fertility.
