运用二次回归旋转组合设计,研究不同密度和氮肥对绵油11制种产量的影响,通过模拟寻优,得出密度298785株/hm~2,纯氮196.35kg/hm~2的最佳模式。
The effects of different densities and nitrogen fertilizers on the seed production of Mianyang 11 were studied by means of quadratic regressive rotation combination design. Through optimization, the best model with density of 298785 plants / hm ~ 2 and pure nitrogen of 196.35kg / hm ~ 2 .
