绿地草坪混播组合方案灰色—回归最优设计

The Grey-regression Optimum Analysis of the Ornamental Turf Mixed Seeding Programs

运用三因素饱和最优设计原理和灰色局势评价方法 ,对以草地早熟禾为建群种 ,混播紫羊茅、多年生黑麦草的绿地草坪组合方案进行了灰色—回归最优分析 .结果表明 ,当草地早熟禾占 6 2 %,紫羊茅占 2 0 %,多年生黑麦草占 18%,总播种量为 15 5 g/m2

This paper was studied the optimum combination program of mixed seeding ornamental turf by using the principle of three factors sturated the best design and method of the grey game dicision.The result showed that the optimum combination for ornamental turf was 62% Keturcky blugrass +20% Red fescue +18% Perennial rergass and 15.5 g/m 2 total seeding number is the best design under the environment condition and the management level of this experiment.
