摘  要:
两系籼型杂交水稻桂两优2号是广西首个超级稻品种,由广西农业科学院水稻研究所育成,具有高产、稳产、抗倒伏、适应性广等特点。桂两优2号可作早、晚稻两用,并且早稻产量高于晚稻。试验结果表明,结实率高和单位面积颖花量大是桂两优2号作早稻比作晚稻产量高的主要原因,并提出了缩小晚稻与早稻产量差距的栽培管理技术。

摘  要:
Guiliangyou 2 is the first super rice variety of Guangxi Province,bred by rice research institute of Guangxi academy of agri-cultural sciences,with the characters of high and stable yield potential,wide adaptability and high lodging resistance.Guiliangyou 2 can be grown as both early rice and late rice,the yield of early season rice was higher than that of late season rice.The results indi-cated that higher grain yield of early season rice was partly rely on greater spikelets per m2and higher seed setting rate.Some cultivation techniques were suggested to reduce the yield difference.
