摘要
通过产量构成要素来研究水稻不同时期施用氮肥比例对水稻产量的影响。结果表明:施氮比例为基肥50%、蘖肥30%、穗肥20%的处理产量最高,为506.92 kg/667 m^2,增产率为26.3%,增产效果最明显。
The effect of N fertilization ratio at different stage on the yield of rice could be studied by yield components and the results showed that the treatment of 50% basal fertilizer, 30% tiller fertilizer and 20% panicle fertilizer reached the highest yield, 506.92 kg/667 m^2, and the yield increase rate was 26.3%.
