| 摘 要： | 采用小区对比试验方法,探讨了氮肥运筹对水稻新品种盐粳188生育及产量的影响。结果表明:基蘖肥与穗肥比例为2∶5∶3的B处理单位面积有效穗数、颖花数、抽穗至成熟期干物质积累量占产量的百分比及结实率、氮素利用率均高于其他处理,产量达720.45 kg/667 m2,分别比C(3∶4∶3)、D(3∶5∶2)、A(2∶4∶4)处理增产1.11%、2.93%、7.83%。

| Abstract: | Using plot comparison experiment,the effect of nitrogen operation on the yield of Yanjing 188,a new rice variety,was discussed.The results showed that the effective panicles and flowers per area,the percentage of dry matter accumulated from heading to maturing to total grain weight,kernel set and nitrogen utilization efficiency obtained in treatment B,the basal fertilizer: tiller fertilizer: panicle fertilizer being 2:5:3(2:5:3),were more than those of control.The treatment B got the yield of 720.45 kg/667 m2,higher than treatment C(3:4:3),treatment D(3:5:2) and treatment A(2:4:4) by 1.11%,2.93%,and 7.83%,respectively. |
