摘　　要：为建立大穗型杂交粳稻组合氮肥高效管理模式,通过田间小区试验,研究了氮肥不同运筹方式对杂交粳稻组合辽优5218产量的影响。结果表明,辽优5218在两种氮肥运筹方式下,蘖肥施用时期均以6月4日和6月17日两次分施效果为佳。其中,基、蘖、穗肥比例为3∶5∶2时,产量最高,达到10 430.2 kg/hm2。To build up a high efficient nitrogen management mode for large - spike hybrid japonica, the effect of different nitrogen fertilizer management modes on the yield of Liaoyou 5218 was studied by field experiment. The results showed that the yield of Liaoyou 5218 in treatment of tillering fertilizer was applied at June 4 and June 17 was higher under two nitrogen fertilizer management modes. Among them, the highest yield of Liaoyou 5218 reached 10 430. 2 kg/hm2 when the ratio of basal, tiUering and panicle nitrogen fertilizer was 3： 5： 2.
