摘　　要：论述了两系杂交水稻培两优3076在江苏省规模制种产量不高的原因和相应的技术对策。低产原因为秧苗长势差、有效穗不足、父本花期短、花粉量不足。技术对策是稀播匀播、培养带蘖壮秧、提高整田质量、防止草害、合理安排行比、栽足基本苗、攻促结合、促进父母本平衡生长。The causes of low-yield in large scale seed production in Jiangsu for two-line hybrid rice Peiliangyou3076 were discussed and the corresponding technical countermeasures were put forward. The main causes of low-yield were the inferior growth potential resulting in deficiency of effective panicles, and the short florescence of male parent leading to insufficient pollens. The technical strategy were seeding sparsely and evenly,cultivating stronger seedling with tillers,preparing field carefully to avoid weed spreading, reasonable arrangement of the line ratio of male and female, transplanting enough seedlings and promoting balanced growth of the parents by fine management of water and fertilizer.
