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/hm2 的处理组合产量较高
Using split zone test method, the optimal combination of nitrogen application rate and seeding density of Liangyou Peijiu under direct seeding condition was explored. The results showed that the yield of medium fertility field was higher than that of the control group with nitrogen application rate of 80kg / hm2 and seeding rate of 18.75kg / hm2
