| 摘 要： | 以超级稻品种沈农265和主栽品种辽粳294为试材,比较氮肥对2品种分蘖、株高、物质生产与分配的影响。结果表明:不同肥力下,2品种均在6月27日达到分蘖高峰,与辽粳294相比,沈农265达分蘖高峰时分蘖数少;株高受氮肥的影响较大,沈农265的穗颈节间明显长于辽粳294,茎秆基部前者短于后者;叶鞘的物质输出率高于叶片,茎秆的物质输出率为负值。

| Abstract: | The typical super rice-Shennong 265 and main cultivated rice-Liaojing 294 were used as experimental material to compare the influence of nitrogen fertilizer on tiller,plant height,matter production and distribution.The result showed: two rice varieties reached peak of tiller on July 27 under different nitrogen condition.Tiller number of Shennong 265 was less than that of Liaojing 294.Influence of nitrogen fertilizer on plant height was great.The spike stem of Shennong 265 was clearly longer than that of Liaojing 294,and the stem basis of the former was obvious shorter than that of the latter.The export of dry matter of leaf shelf was greater than that of the leaf. |
