Abstract
[目的]为南昌市乃至江西省超级晚稻的推广应用提供参考依据.[方法] 对3个超级晚稻新组合(丰源优299、天优998、淦鑫688)与金优桂99的产量、生育期等进行比较分析.[结果] 3个超级晚稻新组合较金优桂99产量均有极显著增加(P<0.01),且丰源优299>天优998>淦鑫688;全生育期丰源优299为114 d,天优998为119 d,淦鑫688为121 d,分别较CK短4 d,长1 d,长3 d;3个超级晚稻株叶形态好,茎秆粗壮,耐肥抗倒性好.[结论] 丰源优299应列为江西省首推超级晚稻,中迟熟超级晚稻天优998、淦鑫688宜结合早熟早稻茬口合理安排,在晚稻生产中示范推广.
