饱和D-最优设计在混播种草中的研究应用

APPLYING THE MOST EXCELLENT DESIGN AS D-SATURATION TO STUDY ON MIXTURE SEEDLING OF PLANTING GRASS

采用饱和D -最优设计方法 ,研究燕麦与箭豌豆的混播比例与牧草产量的关系 ,通过测定两种牧草不同播种密度试验的各项参数 ,建立两种牧草不同播种密度对牧草产量的函数模型 ,同时确定了两种牧草的最佳混播比例为 ,燕麦 5 5 % ,箭豌豆 45 %。

The relationship between mixture ratio and herbage yield about oat and common Vetch, was studied by the most excellent design as d-saturation. The function madel of herbage put out for different sown pasture sowing density and determined the best mixture ration of the two herbages, that was oat a percent age of 55 and vetch of 45.
