摘要
江优919与江两优3号为贵州新引进的杂交稻品种,为探索两品种适宜的栽培密度,开展了4个不同密度试验。结果表明:江优919单产比江两优3号单产高17.8kg/667m2,高3.0%。江优919与江两优3号均以12 346穴/667m2(30×18cm)时单产最高。生产上,江优919与江两优3号推荐机插秧密度为12 346穴/667m2(30×18cm)。
Jiangyou 919 and Jiangliangyou No.3are new hybrid rice varieties introduced into Guizhou in currentyears,in order to explore the appropriate planting density,4different planting densities were studied.The results showed that yield of Jiangyou 919 is 17.8kg/667m2 higher than Jiangliangyou No.3,3% higher.Both varieties at planting density of 12346hills/667m2(30×18cm),the yield were the highest.So planting density of 12346hills/667m2 was proposed on production of Jiangyou 919 and Jiangliangyou No.3.
