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 m2。

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.

Key words: double cropping late rice, H you 518, machine transplanting, sowing date, seedling age
