| 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。

| 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 assimi lation rate |
