| 摘 要： | 为了探讨不同生态条件下超级杂交稻氮素吸收利用的基因型差异及其产量表现，2007年在长沙、桂东和南县进行了大田栽培试验。结果表明：（1）超级杂交稻地上部植株氮素吸收量的基因型差异显著．其中准两优527最高，3地点平均为155．3kg／hm^2，两优293最低，3地点平均为129．6kg／hm^2；（2）不同超级杂交稻产量显著高于对照品种汕优63和常规稻品种胜泰1号，10个品种3地点平均产量为9．22t／hm^2，比对照品种增产12．1％；（3）超级杂交稻氮素需要量均低于对照品种汕优63和常规稻品种胜泰1号，不同基因型品种间存在较大差异，10个品种3地点平均为14，53～17．21kg／1000kg。 |

| Abstract: | To clarify the genotype differences in nitrogen absorption and utilization of super hybrid rice and its yield performance under different ecological conditions,field experiments were conducted in Changsha,Guidong and Nanxian of Hunan province in 2007.The results showed that there were significant genotype differences in nitrogen absorption amount in shoot of super hybrid rice,that of Zhunliangyou 527 was highest and that of Liangyou 293 was lowest,and their average of 3 locations was 155.3 kg/hm2 and 129.6 ... |
