摘　　要：通过3次烟区土壤养分调查结果分析,近10年来烟区土壤主要养分发生了变化:烟区有机质得到有效的恢复,主要养分基本保持稳定,全氮与碱解氮含量有亏缺,全氮对有机质的依赖性增强,碱解氮对全氮的依赖性降低,有机质的恢复是保持土壤全氮水平的重要因素;全磷含量减少较多,速效磷含量有增长,全钾和速效钾含量分别有增长;水溶性硼、有效态锌已得到补充,有效态锰水平降低。对兴山烟区29个重点村11项主要养分数据的聚类,对产区重新进行了施肥技术分区,提出增加有机质,增硼,减磷等施肥措施。Major soil nutrients changed in tobacco growing areas since 2000 in Xingshan of Hubei province.With continued organic fertilizer application,oganic matter recovered effecitively while main nutrients remained stable.In the mean time,total nitrogen and available nitrogen which were highly dependent on organic matter decreased.Total phosphorus content reduced even more,total potassium and available potassium increased to some extent,water soluable boron and zinc were being supplemented while effective manganese reduced even further.Result of cluster analysis of 11 key nutrients data from 29 villages suggested to increase organic matter and boron application while reduce phosphorus fertilization.
