| 摘 要： | 通过不同施肥时期试验,研究不同施肥时期对不同穗型水稻品种群体结构及产量的影响,其目的是为寒地水稻生产提供理论支持和技术指导。笔者研究结果表明,穗数型品种‘牡丹江19’群体结构、产量最佳的处理为分底肥、蘖肥和粒肥3次施入的处理,比其他处理增产17.9%～34.3%。穗重型品种‘系选1号’群体结构、产量及产量构成因子最佳的处理为分底肥、蘖肥、穗肥和粒肥4次施入的处理,比其他处理增产8.3%～22.6%。 |

| Abstract: | The effects of fertilization time on population structure and yield of different rice panicle type were studied by different fertilization time experiment. The results showed that population structure and yield of rice panicle number type‘Mudanjiang 19’were the best when fertilizers were applied as base, tillering and granular fertilizer, and the yield was increased by 17.9%-34.3%. But population structure, yield and yield component factors of rice panicle weight type‘Xixuan 1’were the best when fertilizers were applied as base, tillering, panicle and granular fertilizer, and the yield was increased by 8.3%-22.6%. |
| Keywords: | fertilization time panicle type population structure yield component factor yield |
