摘　　要：以宝鸡烟区主产烟县2015年184个土壤样品与2012年207个土壤样品主要养分指标为基础数据,并进行了年份间和不同烟区间的对比分析。结果表明:氯离子总体上处于适宜或较高水平;有机质含量有增加的趋势,59%的样品有机质含量仍偏低;有效磷、速效钾含量适宜的比例有显著提升;66.3%碱解氮含量偏高;77.72%有效锌在低和严重偏低的范围。陇县植烟土壤养分总体状况明显好于麟游。Based on the main nutrient indexes of 184 soil samples collected in 2015 and 207 soil samples collected in 2012,two tobacco-growing areas were compared and analyzed between 2012 and 2015. Results showed that soil available chloride ion was at appropriate or higher level in all samples. The soil organic matter showed increase trend, but the organic matter content in 59% soil samples was still at the low level. The proportion of soil available phosphorus and available potassium at suitable level for tobacco growth increased significantly. 66.3% soil samples bad higher available nitrogen content, and available zinc in 77.72% samples was at low or serious low range. Compared the comprehensive soil nutrients, Longxian tobacco- growing areas was superior to that in Linyou.
