| 摘 要： | 以超级晚稻H优518为试验材料,进行播期和秧龄的双因素试验。结果表明,该品种可在同生态区域作双晚机插,最迟安全播种期在7月1日前后,秧龄15~20 d移栽,可在武汉市"寒露风"的常年出现日期9月18日前后安全齐穗;播、插期越早,安全性越高,丰产性越好,最高单产可达723.4 kg/667 m~2。

| Abstract: | A field experiment was carried out about different sowing date and seedling ages on supper late rice H you 518.The results showed that H you 518 could be used as machine transplanting double cropping late rice.The optimal seedling age is 15～20 days,the latest safe sowing date is July 1,and the full heading stage should before September 18th.The higher yield would be obtained when sowing date and planting date is earlier. |
