S274; [目的]探究不同移栽密度与穗型品种对再生稻产量形成的影响.[方法]采用两因素裂区试验设计,以移栽密度为主区(D1:15万穴/hm2、D2:18.75万穴/hm2、D3:22.5万穴/hm2、D4:26.25万穴/hm2、D5:30万穴/hm2、D6:33.75万穴/hm2),品种为副区(TYHZ:多穗型品种天优华占、HLY898:穗粒数兼顾型品种徽两优898、YLY900:大穗型品种Y两优900).[结果]品种类型和移栽密度对头季产量构成及周年产量均有显著影响,但不存在显著性交互作用.穗粒数兼顾型品种HLY898头季产量最高,产量因子之间协调能力强,结实率高,周年产量也最高,其次是多穗型品种TYHZ,头季分蘖能力强,成穗率高,有效穗数足,头季和周年产量均显著高于大穗型品种YLY9...
