摘　　要：通过2000年及2010年兴山烟区土壤大量取样测定,对烟区土壤主要养分及微量元素的动态变化进行跟踪比较。结果表明,自2000年后的烟叶施肥措施已影响到土壤营养。有机质得到阶段性恢复;主要养分基本保持稳定,全氮与碱解氮含量有一定亏缺,全磷含量大幅度降低,速效磷含量增长,全钾和速效钾含量均有一定的增长;水溶性硼、有效锌已得到较好的补充,但有效锰有一定恶化。烟叶生产中,稳定有机肥、氮肥施用的同时,适当调整全磷及速效磷营养,提高全磷含量,维持并提高有效钾的含量,同时需重视有效锰的补充。The dynamic changes of soil nutrients in Xinshan tobacco area were studied through collecting a large number of soil samples in 2000 and 2010.The results showed that the soil nutrition in tobacco-growing areas of Xingshan since 2000 had been affected by fertilization.In detail,the organic matter was restord to some extent;and the main nutrients remained stable.The content of total nitrogen,available nitrogen,and total phosphorus was decreased to some extent,while the content of available phosphorus was increased.The content of total potassium and available potassium got a certain increase.Besides,the content of water-soluble boron and available zinc was increased;but the content of available manganese was decreased in a manner.Therefore,in tobacco production,stabilizing organic fertilizer and nitrogen fertilizer application,adjusting total phosphorus and available phosphorus nutrition,increasing the amount of total phosphorus supplement,maintaining and increasing the effective state of potassium,and increasing the application of manganese fertilizer were important.
