| 摘 要： | 水稻“两段”育苗不同品种筛选试验,设置了垦稻10、松粳6号、哈99-774两段育苗试验处理,以当地品种莎莎妮常规栽培为对照。试验结果表明：这些品种两段育苗均表现为秧龄长,秧苗素质增强,返青、分蘖、抽穗早。其中垦稻10和松粳6号品种熟期适宜,产量分别是652.3、635.6 kg/667 m^2,较海伦市常规品种增产152.9、136.5 kg/667 m^2,纯增效益225.2、195.7元/667 m^2,99-774品系没能安全成熟。

| Abstract: | Taking the local rice variety Shashani as control, a rice variety screening experiment was conducted with Kendao 10, Songjing 6 and Ha 99 as entries through two-stage seedling nurturing. The results showed that these varieties were characterized with long leaf ages, improved seedling quality, and early green-turning, tillering and heading. Kendao 10 and Songjing 6 matured normally and yielded 652.3 and 635.6 kg/667 m^2, respectively, more than that of local variety in Hailun City by 152.9 and 136.5 kg/667 m^2, and the net returns were increased by 225.2 and 195.7 Yuan RMB/667 m^2. The line, 99-774, did not mature safely. |
