| 摘 要： | 以不同穗型水稻品种为试材，研究不同氮素水平对水稻生理特性的影响，结果表明：高氮水平下，两品种叶片中叶绿素含量、剑叶含氮量、单叶及群体光合速率、叶面积指数均高于低氮处理，下降速度也比低氮处理慢．这可能是直立穗型品种抽穗后物质生产能力强的生理原因． |
| 关 键 词： | 水稻 穗型 叶面积指数 叶绿素含量 光合速率 |

| Abstract: | Using different panicle rice varieties as materials,their physiological characteristics in different levels of nitrogen weve studied.These results demonstrate that chlorophyll content of leaves,nitrogen content of flag leaf,photosynthetic rate of plant population and LAI in high nitrogen fertilizer condition were all higher than those in low nitrogen fertilizer condition,and decreased slowlier than the latter.It perhaps was the physiological reason that the ability of the high dry matter production of the erect panicle variety. |
| Keywords: | Rice Panicle LAI Chlorophyll content Photosynthetic rate |
