| 摘 要： | 选用超级稻品种沈农265和辽宁省主栽品种辽粳294为试材，研究田间低钾对超级稻生长和物质转移的影响．结果表明：田间低钾使供试品种生长缓慢，叶片、叶鞘、茎秆和穗子的增长速度都慢于正常供钾条件；增施钾肥有助于提高沈农265叶片和叶鞘的物质转移。两品种茎秆的物质输出均为负值；钾肥影响茎秆的粗度，对辽粳294影响更大。所以生产上为了防止水稻倒伏，要注意钾肥的施用． |

| Abstract: | The typical super rice- Shennong 265 and main cultivated rice- Liaojing 294 were used to study the influence of low potassium condition in field on growing and matter transportation. The result shows： Rice grows slowly under low potassium in field, leaf, leaf shelf, stem and spike grow more slowly than that under normal potassium condition. Applying potassium is contribute to improve the matter transportation of Teaf and leaf shelf of Shennong 265. Exporting of stem is negative, Potassium influences stem width, and the influence on Liaojing 294 is very great, so preventing from lodging in product, we must pay attention to applying potassium to rice. |
