| 摘 要： | 在大田条件下研究了草地早熟禾(Poa pratensis)、多年生黑麦草(Lolium perenne)和紫羊茅(Festuca rubra)不同混播比例组合对草坪综合质量的影响, 以期为北方地区草地早熟禾、多年生黑麦草和紫羊茅混播建植草坪提供实践依据。结果表明, 草地早熟禾、多年生黑麦草和紫羊茅混播建植草坪, 在多年生黑麦草比例为20%不变的情况下, 建坪初期, 草地早熟禾比例越小或紫羊茅比例越大, 则草坪密度越大, 质地越优, 草坪颜色越绿, 地下植物量越小, 地上植物量呈先减小后增大的趋势。综合各种草坪质量评价指标, 3种冷季性草坪草混播最佳比例为, 草地早熟禾:多年生黑麦草:紫羊茅=1:2:7。

| Abstract: | This experiment studied the impacts of the mixed sowing proportion of Kentucky bluegrass, perennial ryegrass and red fescue on turf quality in field conditions in order to provide practical basis for the mixed sowing of these 3 turf grasses in the northern area of China. The results showed the turf with the lower proportion of Kentucky bluegrass or the higher proportion of red fescue fixed with 20% of perennial ryegrass, had greater density, better texture, more green, smaller underground biomass.The optimal mixed sowing ratio of these three cool-season turfgrasses was Kentucky bluegrass:perennial ryegrass:red fescue=1:2:7 after comprehensive analysis all of the turf quality indices. |
