| 摘 要： | 以超级稻“盐丰47”为材料，采用小区对比试验方法，探讨了氮素基蘖穗肥不同施入比例对滨海稻区水稻产量及氮磷吸收量的影响。结果表明:基肥、蘖肥、穗肥比例2∶5∶3的B处理，获得了单产978thm2，比A（2∶4∶4）、C（2∶6∶2）和D（2∶8∶0）处理分别增产了06%、34%和56%；其单位面积有效穗数及颖花数、干物质产量及齐穗后干物质积累量占子粒产量百分比、氮磷吸收量均较高。因此适宜增加氮素穗肥施入比例有利于水稻产量与氮磷吸收量的增加。

| Abstract: | Super rice′yanfeng 47′was used as materials，using plot contrast test method to investigate the effects of the different ratios of nitrogen base tiller ear fertilizer on development and yield of rice in coastal rice region.The results showed that the ratios of base tiller ear fertilizer was 2∶5∶3 in the B treatment got 978 thm2 per unit yield，comparing with the treatment of A（2∶4∶4）、C（2∶6∶2）and D（2∶8∶0），the yield increased 06%、34% and 56%.The effective panicle number and spikelet numbers per unit area，dry matter yield，dry matter accumulation，full heading accounted for the percentage of yield and N，P uptake were all higher than the others.With the increasing proportion of panicle fertilizer was beneficial to increasing the yields and N P uptake of rice. |
