| 摘 要： | 经过3 a对超级稻吉粳88号等3个不同类型水稻品种的氮肥施用量试验,结果表明:氮肥施用量对不同类型品种的株高生长和叶龄增长影响不大;多蘖型品种在低肥条件下,容易取得更多的有效穗数而实现高产;大穗型品种对氮肥施用肥量不敏感,分蘖发育慢,有效分蘖率高,在高肥条件下高产。

| Abstract: | The results of N application experiment on three types of rice varieties showed that the effect of N amount on plant height and leaf age was not significant.Multi-tiller variety was easy to realize high yield at low N amount due to much more effective panicles.However,large-panicle variety was not sensitive to N amount and reached high yield at high level of N amount |

| Keywords: | Super rice Nitrogen application amount Multi-tiller variety Large-panicle variety |
