| 摘 要： | 采用大田随机区组设计研究了穗肥施氮量对徽两优2115抗倒伏性状及产量的影响。结果表明:穗肥氮肥用量对徽两优2115的株高、抗倒伏系数、产量因素及产量均有不同程度的影响。氮肥施用量以底肥(纯N)69 kg/hm2、蘖肥(纯N)69 kg/hm2、穗肥(纯N)138 kg/hm2的处理N4产量最高,较不施穗肥的对照N0(ck)增产3 258.1 kg/hm2,增幅达40.7%,增产达极显著水平。 |

| Abstract: | By methods of field trials and randomized blocks design,the influences of amount of panicle fertilizer application on lodging resistance and yield of hybrid rice‘Huiliangyou 2115'by throwing cultivation had been studied.The results indicated that amount of nitrogen fertilizer application had different effects on the plant height,the lodging resistance traits,the yield component and the production.The rice yield of N4 treatment was the highest.The yield increased by 3258.1 kg/hm2 compared with to the CK.The increase amplitude was 40.7% and reached the extreme significant level. |
| Keywords: | Panicle fertilizer Nitrogen application amount Hybrid rice Yield Lodging resistance |
