| 摘 要： | 试验结果表明,当施氮量一定的情况下,增施磷、钾肥,氮肥利用率和水稻的产量都有显著的增加。谷粒产量和氮肥利用率为29.78g/盆和44.37％,分别比对照(单施氮肥)提高22.75％和9.62％。合理施用氮、钾肥,磷肥的利用率也有显著增加(为29.10％),比单施磷肥利用率提高6.88％。

THE ABSORPTION AND UTILIZATION OF NITROGEN AND PHOSPHATE BY RICE IN RED EARTH |

| Abstract: | The experimental results showed that the utilization rate of N and rice yield were significantly increased by applying P and K fertilizer when the same amount of N was appying.The maximum yield of grain and utilization rate of N were 29.78 gram per pot and 44.37%,which were 22.75% and 9.62% higher than those of control(using N only) respectively The utilization rate of P was significantly increased by rational applied N and K fertilizer.The maximum utilization rate of P was 29.10%,which was 6.88% higher than that of using P fertilizer only. |

| Keywords: | utilization rate of N utilization rate of P priming effect red earth |
