| 摘 要： | 不同群体下 ,水稻的光合特性发生明显变化。随着群体变小 ,叶片叶绿素含量增加 ,比叶重加大 ,光合速率提高 ,净同化率下降速度慢 ,下降时间短 ,群体生长率最大值出现时间推迟 ,植株内部通风透光好 ,光合作用强。

| 关 键 词： | 水稻 比叶重 光合速率 净同化率 |

| Abstract: | The photosynthetic characters of rice were different in different plant populations. With the decrease of population, the chlorophyll content and specific leaf weight increased; while the net assimilation rate decreased for a short time; the maximum population growth rate was postponed; plants were well ventilated and high in photosynthetic rate. |

| Keywords: | rice specific leaf weight photosynthetic rate net assimilation ra |
