摘　　要：采用裂区试验方法 ,探索了两优培九在直播条件下施氮量与播种密度的最佳配合。研究结果表明 :在中等肥力田块以施纯氮 2 80kg/hm2 、播种量 18.75kg/hm2The best combination of planting density of hybrid rice-Liangyoupeijiu under directly sowing and the amount of N-fertilizer application was selected through the experiment, which showed that the amount of seeding Liangyoupeijiu and N-fertilizer application was 18.75 kg/hm 2 and 280kg/hm 2 was most suitable for high yield.
