摘要
烟叶含钾量的高低是评价优质烟叶的重要指标．统计和分析2003～2008年云南大理州烤烟含钾量的状况，结果表明云南大理州烤烟含钾量总体趋势不高．因此，应以土壤测定数据为依据，合理施用钾肥，采用深施和集中施肥，可提高钾肥利用率，提高烟叶的含钾量，生产出优质烟叶．
The content of potassium in tobacco is an important target of the assessment of the good quality of tobacco. The statistics and analysis of the content of potassium in the flue-cured tobacco of Dali from the year 2003 - 2008 resulted that the content of potassium in the cured tobacco of Dali was not high. So itg necessary to be based on the data of soil test, reasonably using potassium in deep and central fertilization so as to increase the availability of potassium, the content of potassium of tobacco to produce good quality tobacco.
