| 摘 要： | 通过对叶龄诊断施肥法和常规施肥法做对比试验,结果表明叶龄诊断施肥法产量明显高于常规施肥法;两种施肥方法穴穗数、结实率和千粒重差异不显著,而穗粒数有显著差异,且穗粒数与产量呈极显著正相关;其叶龄诊断法在氮肥为200kg/hm2时产量最高达9 750.3kg/hm2. |

| Abstract: | The contrast test of two fertilizering methods were conducted,which were leaf age diagnosis method and conventional method.The results indicated that the yield with adopting the former fertilizering method was higher than that of the latter.The differences of panicle number per socket,seed setting rate,1000-grain weight were not significant,while the number of grains per panicle had significant differences and the positive correlation between number of grains per panicle and yield was found.The highest yield under the leaf age diagnosis method was 9 750.3 kg/hm~2 at 200 kg/hm~2 N fertilizer lever. |
| Keywords: | rice leaf age diagnosis fertilizering method conventional fertilizering method yield |
