摘要
为应对钦州市秋冬春三季连旱对水稻生产的威胁,在旱区对7个超级稻品种(组合)进行了再生栽培对比试验。结果显示,早稻平均产量以两优培九最高,其次为Y两优1号、新两优6号;晚稻再生稻的平均产量以两优培九最高,其次为中浙优1号、特优航1号;年均产量以两优培九最高,其次是中浙优1号,其他超级稻品种(组合)的年平均产量也比普通杂交稻(对照)的高。综合各参试超级稻的产量结果、田间表现、稻米品质、生长势与再生能力等因素分析,以中浙优1号、两优培九两个品种(组合)最为理想,可作为今后钦州市超级稻再生栽培的主推品种(组合)。
In order to cope with the threat of continued drought to rice cultivation in autumn, winter and spring in Qinzhou City, the ratoon cultivation tests of seven super rice varieties （combinations） were carried out in drought regions. The results showed that the average yield of Liangyoupeijiu in early rice was the highest, followed by Y liangyou 1, Xin- hangyou 6. The average yield of Liangyoupeijiu in late rice was the highest too, followed by Zhongzheyou 1, Teyouhang 1. The annual average yield of Liangyoupeijiu was also the highest, followed by Zhongzheyou 1, the annual average yield of other varieties were higher than the control hybrid flee. According to the yield, field performance, grain quality and growth vigor and ratoon ability and so on, the varieties Zhongzheyou 1 and Liangyoupeijiu were the best and could be extended in ratoon cultivation of super rice.
