| 摘 要： | 通过田间试验 ,研究了烤烟生长后期烟株内钾素的积累和分配。结果表明 ,烟株内的钾素积累在打顶后有一上升的过程 ,进入烟叶成熟期后则表现出下降的趋势。留顶和施加外源生长素可以使成熟期烟株内的钾素积累维持在较高的水平 ,同时钾素向叶中的分配以外源生长素处理 2次的最多。成熟叶片中的含钾量也以留顶和外源生长素处理 2次的较高。 |

| Abstract: | The mechanism of accumulation and distribution of potassium in flue\|cured tobacco plant during the later period of growth was studied by field experiments. The results showed that the accumulation of potassium in tobacco plant tended to increase after topping, and to decrease during the ripening process. The higher accumulation rates of potassium in tobacco plant could be maintained by applying NAA or keeping its top unremoved, and the highest distribution rates of potassium in leaves was found when applying NAA twice. Potassium content was higher in the matured leaves applied with NAA twice or not topped. |
