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。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、蘖肥和粒肥三次施入的处理，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、穗肥和粒肥四次施入的处理，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%.
