| 摘 要： | 对旱育秧和湿润育秧苗床温度变化及秧苗素质的比较表明；旱育秧苗床膜内日平均温度、有效积温高．昼夜温差大；移栽叶龄小、叶片小，根系发达，植株矮壮；干物质积累多，充实度高，比叶重大，比根长小；增产幅度为6．92％～12.22％。

| Abstract: | The mean daily tempaeratures and the effective accumulated temperatures were hightcr, the diurnal temperature ranges were wider of dry nursery bed (A,), as compared with wet nursery bed (A,). Transplant age younger, leaves smaller, root more developed, plant shorter and stronger, more dry matter accumulated, plumpness higher, ratio of leaf weight higher,ratio of root length lower of dry bed seedlings as compared to those of wet bed seedling. Increased by 6. 92%-12. 22% in yield likewise. |

| Keywords: | early hybrid rice dry nursery bed bed temperature seedling quality yield |
