| 摘 要： | 凉山州高原粳稻在自然环境中抽穗后3～4d开始开花，5～8d进入开花盛期，10～12d相继结束；1日内的开花时间主要集中在12：00～16：00；每朵颍花开花历时60～110min不等；闭花授粉粒和停止发育粒教因品种而异；水稻开花与颖壳内湿度、田间温度和生态区关系密切。

| Abstract: | Study reveals that Japonica rice growing on plateau blooms three or fours day after heading;it reaches the peak period of blossom after five to eight days and the blossom period ends after ten to twelve days.The blossom time in a day is mainly during 12:00 p.m and 16:00 p.m.Pollination in closed blossoms and non-growing grains differ from variety to variety.Rice blooming is closely related to the humidity in caryopsis,field temperature and ecological region. |
