| 摘 要： | 为探明凉山烤烟钾含量状况,试验采集凉山2006～2009年8个植烟县市烟叶样品共1318份,对烤烟钾含量的总体状况以及不同部位、品种、产地和年际间烤烟钾含量的变化特征进行了研究,并与国内外优质烤烟钾含量进行比较。结果表明:凉山烟叶钾含量平均值为2.22%,最小值为0.40%,最大值为4.08%,变异系数较大,为25.59%;部位间钾含量的分布特征表现为:下部叶>中部叶>上部叶;主栽烤烟品种中钾含量分布规律为:云烟87>云烟85>红花大金元;整体上凉山各植烟地区烟叶钾含量分布不均衡,以越西、冕宁钾含量最高,分别为2.64%和2.59%,会东县烟叶钾含量最低,为1.85%,年际间钾含量呈逐年下降的趋势。与国内外优质烤烟相比较,凉山下部叶钾含量处于中等水平,中部叶钾含量处于中等偏下水平,上部叶钾含量偏低。 |

| Abstract: | In order to ascertain the status of potassium content in flue-cured tobacco in Liangshan,the general status of potassium content in flue-cured tobacco and the change characteristics of potassium content in different positions and varieties of flue-cured tobacco,different producing areas and years were studied with 1 318 tobacco samples which were collected from eight tobacco planting counties in 2006～2009,and a contrast analysis was conducted between the potassium content in tobacco from Liangshan and that in high-quality tobacco from China and abroad.The results showed that the average potassium content in tobacco from Liangshan was 2.22% with the minimum value of 0.40% and the maximum value of 4.08%,the coefficient of variation was large to 25.59%.The distribution characteristics of potassium content in different positions was lower leaf>middle leaf>upper leaf.The distribution characteristics of potassium content in main varieties was Yunyan87>Yunyan85>Honghuadajinyuan.In generally,the potassium content in tobacco from each tobacco-planting area of Liangshan distributed unevenly,among which the potassium content in tobacco from Yuexi and Mianning was the highest with 2.64% and 2.59%,respectively,and that from Huidong was the lowest with 1.85%.The potassium content in tobacco from Liangshan showed a downward trend year by year.In comparison with the high-quality flue-cured tobacco in China and abroad,the potassium content was middle level in lower tobacco leaves,middle-lower level in middle tobacco leaves and low in upper tobacco leaves. |
