随着抛秧稻栽培的推广，抛秧稻合理施肥成为急需研究的问题。以早稻迟熟杂优组合特优６３为试材，在适当比例磷钾肥做基肥情况下，每公顷施纯氮１５０ｋｇ，设计了４组不同施肥期的氮肥分配比例试验。结果表明，杂优抛秧稻的优化氮肥分配模式以８０％作基肥、２０％作穗肥、分蘖肥不施的产量最理想，比其他分配模式的增产６．１％和１１．１％，产量差异极显著 With the promotion of throwing rice cultivation, throwing rice seedlings rational fertilization become an urgent need to study the issue. Taking early maturity early hybrid rice combination Teyou 63 as test material, 150kg pure nitrogen per hectare was applied in the proper ratio of P and K as basal fertilizer, and four different proportion of N fertilizer allocation experiments were designed. The results showed that the optimum nitrogen allocation pattern for hybrid rice with throwing rice was 80% basal fertilizer and 20% for panicle fertilizer. The yield of tillering fertilizer was the best, yielding 6.1% and 11.1% The difference in production is extremely significant
