摘　　要：以超级稻"协优9308"为对照,对"培两优2859"进行不同播种期试验,结果表明:不同播种期处理间生育期、株高、产量及穗粒结构等性状差异明显;"培两优2859"和"协优9308"均以5月10日播种的产量最高,分别达7650.0和8250.0kg/hm2。The super rice ＂Xieyou 9308＂ was chosen as control, the two -line hybrid rice ＂＇ Peiliangyou 2859＂ has been used to study the effect of different sowing dates. The result showed that there were significant differences in growth duration, plant height, yield, panicle and grain structure among different sowing date treatments; the yields of both ＂Peiliangyou 2859＂ and ＂Xieyou 9308＂ were the highest when they were sown on May 10th （the earlier sowing date）, which got up to 7650.0 and 8250.0 kg/hm^2 respectively.
