| 摘 要： | 不同群体下，水稻个体和群体生长发育均发生了变化，群体变小后，水稻个体茎秆变粗。分蘖力增强，分蘖高峰期推迟，优势蘖位消失，成穗率提高，群体变小后，还能使水稻叶面积指数高峰期推迟，最大值变小，抽穗后功能叶叶面积变化。

| Abstract: | Growth and development of the individual and the population for rice has change in different population. After light planting, the stem become thicker, the tillering ability became strong, the tillering climax was postpone, the superiority place of tillering was lost, the spike rate was increase. Light planting can be the climax of leaf area index postpone, the maximum become smaller. After coming into ear, the leaf area of activity has increased. |

| Keywords: | rice leaf decline spike rate tillering |
