摘　　要：以暖季型草坪草狗牙根和冷季型草坪草草地早熟禾为材料, 用二因素二次正交旋转组合设计,对9 个不同混播比例草坪质量进行了综合评价, 并在此基础上建立了草坪质量与狗牙根播种量、草地早熟禾播种量之间显著相关的数学模型。通过模拟寻优, 得出优化混播方案为: 狗牙根播种量1-6234 ～3-1544g/m2 , 草地早熟禾播种量8-8456 ～11-3766 g/m 2 。In a design of square,regressive and arthogonal rotation with two factors,a field trial was conducted using warm season Bermudagrass[ Cynodon dactylon (L.) Pers.] and cool season Kentucky bluegrass( Poa pratensis L.).The turf quality of 9 mixtures was evaluated when these two species were sown in different proportion.The significantly correlative regress model was established between turf quality and sowing quantity of two trufgrasses.The optimal sowing scheme that could gain good turf quality was at a rate of Bermudagrass 1 6234～3 1544?g/m 2 and kentucky bluegrass 8 8456～11 3766? g/m 2 .
