| 摘 要： | 试验结果表明，皖南植烟红壤的烟叶含钾量随施钾量的增加而增加．烟株成熟期根系附近土壤速效钾、交换性钾含量与烟叶含钾量呈明显正相关．增加钾肥用量可以降低烟叶钙含量，提高烟叶Ｋ／Ｃａ值．烟叶氮和烟碱含量随施钾量增加有下降的趋势．施钾量与烟叶还原糖的相关性不明显．

| Abstract: | The results indicated that k content in cured leaves of tobacco planting red earth increased with the potassium rate. A high significant positive correlation between water soluble K in rhizosphere soils of mature period of Flue cured tobacco and K content in cured leaves, R=0.8277(middle leaf). K application reduced Ca content in curde leaf. It could increase the ratios of K/Ca and make the burning of cured leaf better. N content in cured leaf reduced with the potassium rate increased,as well as nicotine content in cured leaf .There was hardly any affection to the sugar content in cured leaf by potassium application. |
