采用小区对比试验方法，探讨了氮肥施入量135．0 kg/hm2、202．5 kg/hm2、270．0 kg/hm2、337．5 kg/hm2、405．0 kg/hm2对水稻新品种盐粳50产量的影响。结果表明，适宜增加氮肥施入量，可促进水稻新品种盐粳50单位面积收获穗数及颖花量、结实率及千粒重的增加，促进水稻增产；若过量增加氮肥施入量则降低植株抗病、抗倒能力，不利于单位面积颖花量及千粒重的增加而造成减产。在本试验条件下，氮肥（N）施入量337．5 kg/hm2的处理获得单产9．46 t/hm2，比4、5、2、1处理分别增产了0．6％、2．9％、5．1％、14．8％。

The effect of nitrogen amounts which were 135.0 kg/hm2、202.5 kg/hm2、270.0 kg/hm2、337.5 kg/hm2、405.0 kg/hm2 on the yield of Yanjing-50 were discussed through comparative test. The results indicated that appropriately increasing nitrogen amounts can increase the effective panicles per unit area, flowers, seed setting rate and 1 000-grain weight, then increase the yield. But over-fertilization of N can reduce the ability of lodging resistance and disease, against the increase of the flowers per unit area and 1000-grain weight and then causes crop reduction. In the experiments, the yield of treatment 3 was highest which were 9.46 t/hm2 and increase production 0.6%, 2.9%, 5.1%and 14.8%than treatment 4, treatment 5, treatment 2, treatment 1.
