| 摘 要： | 以狗牙根和草地早熟禾为材料,用二因素二次正交旋转设计,对9个不同播种比例混播草坪的种群性状进行研究,建立了草坪地上生物量、地下生物量及一致性与狗牙根和草地早熟禾播种量之间显著相关的回归模型。确定了影响草坪性状的主要因子,优化了混播草坪的最佳播种量。

| Abstract: | In a design of square, regressive and arthogonal rotation with two factors, a field trail was conducted using Bermudagrass and Kentucky Bluegrass. The results indicated: The significantly correlative regress model were established between sowing quality of two turfgrasses and the turf characteristics such as biomass, uniform etc. The optimal sowing scheme that could grain good turf quality was at a rate of Bermudagrass 1.84～4.8 g/m2, and Kentucky Bluegrass 10.2～11.2 g/m2. |
