| 摘 要： | 采用小区对比试验方法,设4个处理(基、蘖、穗肥比例分别为2:4:4、2:5:3、2:6:2、2:8:0),探讨了氮肥运筹对水稻盐丰47产量及氮素利用率的影响。结果表明,基、蘖、穗肥比例为2:5:3的处理产量最高,为705.9 kg/667 m2。同时该处理的单位面积颖花数、抽穗至成熟期干物质积累量占产量的百分比、氮利用率以及生产效率均高于其它处理。

| Abstract: | The effect of N management on the yield Yanfeng 47 and nitrogen use efficiency were studied with four treatments,the basal fertilizer:tiller fertilizer:panicle fertilizer being 2:4:4,2:5:3,2:6:2 and 2:8:0,respectively.The results showed that the treatment with the basal fertilizer:tiller fertilizer:panicle fertilizer being 2:5:3 yielded 705.9 kg/667 m2,the highest in all treatments.Meanwhile,the spikelets per unit area,the percentage of dry matter accumulated from heading to maturity to total grain weight,nitrogen utilization efficiency and production efficacy were more than other treatments |

| Keywords: | Rice N management Yield Assimilate N per 100 kg of grain N utilization efficiency |
