| 摘 要： | 通过研究早稻机插、抛秧与手插栽培的分蘖成穗规律,发现这3种栽培方式的分蘖利用均以第4、第5和第6叶位产生的分蘖为主;机插、抛秧和手插分蘖成穗率分别为80.0%、80.0%和95.8%,对产量贡献率分别为49.8%、46.6%和60.0%,说明机插栽培相比抛秧,其分蘖穗穗型较大,对产量贡献也大。

| Abstract: | Based on the study of tillers and panicle formation in early rice with 3 cultivation methods, The author found that the tillers from 4,5 and 6 leaf position were main tillers. The panicle percentage from tillers in machine-transplanted, seedling throwing and hand-transplanted rice were 80.0%,80.0% and 95.8%,and the contributive rate to yield were 49.8%,46.6% and 60%, respectively. The panicle type of machine-transplanted rice was bigger, and had bigger contribution to yield. |
