| 摘 要： | 3 a试验结果表明,随氮肥施用量的增加,株高、有效穗数、每穗粒数、叶龄都有所增加,但成熟度和千粒重有所减少,但这种趋势氮肥施用量超过110 kg/hm2时差距不明显。氮肥施用量140 kg/hm2时产量最高,110 kg/hm2时效益最好。随氮肥施用量的增加,加工品质、外观品质和食味品质都变劣。

| Abstract: | The experimental results in three years showed that nitrogen fertilizer was helpful to increase plant height,effective tillers,grains per panicle and leaf ages,but lowered grain plumpness and 1000-grain weight.However,the trend was not different significantly when the nitrogen amount reached 110 kg/hm2.The yield reached the highest when the nitrogen amount was 140 kg/hm2 and the returns were the highest when the nitrogen amount was 110 kg/hm2.With the increase of nitrogen fertilizer,the milling quality,appearance quality and eating quality decreased. |
