摘　　要：通过对水稻不同基蘖穗肥比例及施氮量的研究,探讨了施用氮肥对水稻产量的影响。试验结果表明:在施氮量为120 kg/hm2,基蘖穗肥比例为6∶4时,产量高达8 589.0 kg/hm2,说明在该施肥量和施肥比例下比较合理。The effect of nitrogen fertilisers on yield were studied by researching the effect of the different proportion of basal fertilizer,tiller fertilizer,panicle fertilizer and nitrogen rate.The result indicated that the high yield of 8589.0 kg/ hm2 can be achieved under the condition of nitrogen amount was 120 kg/hm2 and the ratio of basal fertilizer to panicle fertilizer is 6：4,it explained the fertilizer amount and fertilization ratio were suitably.
