为了探讨超级早稻和晚稻的产量构成和氮磷钾吸收的基因型差异,2007年在湖南省衡阳市、益阳市和岳阳市进行了不同品种的大田栽培试验.结果表明地点间和品种间的产量差异显著,其中:地点间产量以岳阳点较高,平均产量早稻为7.95 t/hm2,晚稻为7.86 t/hm2;品种间产量早稻以陆两优996和中嘉早32最高,平均产量分别为8.03和7.91 t/hm2,晚稻以钱优1号和天优华占产量较高,产量分别达到7.69和7.55 t/hm2.成熟期植株NPK含量和吸收量的品种间差异显著,但与产量的高低不相关.单位产量(1 000 kg稻谷)的NPK养分需要量分别为15.0～18.9,3.29～5.17和13.6～16.49 kg.

To explore the genotype differences in yield components and uptake of N, P and K in super early rice and super late rice, the experiment was conducted with different varieties in Hengyang, Yiyang and Yueyang of Hunan province in 2007. The results showed that the yield differences were significant among both different locations and different varieties. The highest yield was found in Yueyang site. of which averaged as 7.95 t/hm^2 in early rice and 7.86 t/hm^2 in late rice. Among early rice cultivars, yield of LLY996 and ZJZ-32 was higher, averaged as 8. 03 r/hm^2 and 7.91 t/hm^2 respecrively, an...
