| 摘 要： | 通过大田试验研究了氮肥运筹方式对辽星1号和辽优5218分蘖动态、干物质积累和产量的影响。结果表明,辽星1号以处理2（4∶3∶2∶1）的产量为最高,达到771.5 kg/667m2,比处理3（3∶5∶2）增产16.7%,辽优5218以处理3（3∶5∶2）的产量为最高,达到851.3 kg/667m2。减少前期氮肥用量有利于提高水稻的有效穗数,同时,粒肥的施用能够促进水稻的灌浆,提高千粒重。

| Abstract: | Field experiment was conducted to study the effect of N-fertilizer management on the tiller,dry matter weight and yield of japonica cultivar Liaoxing 1 and japonica hybrid cultivar Liaoyou 5218.The results showed that the yield of Liaoxing 1 reached 771.5 kg/667m2 under the treatment of 4∶3∶2∶1,which was increased by 16.7% compared to that under the treatment of 3∶5∶2.The highest yield of Liaoyou 5218 was 851.3 kg/667m2,which was found under the treatment of 3∶5∶2.It was found that reducing the amount of N-fertilizer in prophase was helpful to improve the effective panicles of rice.Meanwhile,the application of granular fertilizer would promote rice grain filling,and improve the 1 000-grains weight. |
