摘　　要： 利用中国科教网化学数据库烤烟钾含量数据,对我国几个烟区的烤烟钾含量特征及各烟区主要品种的烟叶钾含量进行了初步研究。结果表明,我国烤烟钾含量地区间差异较大,烟叶钾含量南方高北方低,北方烟区烟叶钾含量变异程度大于南方烟区;同一个烟区不同烤烟品种烟叶钾含量存在一定的差异。 Basing on the data of year 2003 and 2004, this paper analyzed potassium content of Flue-cured tobacco in several primary tobacco-planting area of China. The result indicates that potassium content of Flue-cured tobacco in all of these areas was lower then foreign. Differences among these areas was very large, potassium content of Flue-cured tobacco of north area was much lower then south area, and variability of potassium content of Flue-cured tobacco of north area was much bigger then south area; In some tobacco-planting area, difference of potassium content among different varieties was existent.

关 键 词： 烟区 烤烟品种 钾含量 差异
