| 摘 要： | 以＂盐丰47＂为材料,采用小区对比试验方法,探讨了磷肥不同施量对水稻生育性状及产量的影响。结果表明,适量施入磷肥可促进水稻单位面积有效穗数、颖花数、干物质积累量以及齐穗后干物质积累量占籽粒产量百分比的增加。磷肥（P2O5）施入量6.0 kg/667 m2的处理P2获得单产594.8 kg/667 m2,比P1.5、P1、P3、P4、P0处理分别增产了0.7%、2.0%、2.2%、4.6%、5.3%。

| Abstract: | Using Yanfeng-47 as material to discuss the effects of different phosphorus fertilizer amount on rice yield, growth situation and utilization efficiency. The results indicated that the effective panicles, spikelets and dry matter accumulation were increased with appropriate phosphorus fertilizer amount. The yield with phosphorus fertilizer amount of 6.0 kg/667 m2 was 594.8 kg/667 m2, which was increased 0.7%,2.0% ,2.2%,4.6% and 5.3% than P1.5 ,P1 ,P3 ,P4 and P0 respectively. |
