| 摘 要： | 通过田间小区试验研究中期不同氮肥追施比例对水稻产量及米质的影响,结果表明,减少穗肥施用量有利于提高米质,而不利于提高产量。并提出,在北方粳稻栽培区,每公顷氮肥施用量在120kg纯氮的条件下,补肥和穗肥的施用量应各为总氮量的30%为宜。

| Abstract: | Research the different proportion on additional nitrogenous fertilizer has the influence on the yield and quality of rice, the result indicated that less earing fertilizer is propitious to improve the quality, but it is against to improve the yield. At. the same time, in north japonica rice region, make it a condition that fertilizing amount is 120 kg/hm2(pure nitrogen), supplemental fertilizer and earing fertilizer should be used both are 30% of amount nitrogen. |

| Keywords: | metaphase proportion of additional fertilizer yield quality of rice |
