摘　　要：【目的】铺装式混合草坪是近年新研发的一种混合草坪,其人造草为编织型,天然草多采用播种方式建植。比较多年生黑麦草、草地早熟禾和高羊茅在铺装式混合草坪的建植效果,为铺装式混合草坪建植提供技术参考。【方法】选用运动场草坪常用的多年生黑麦草、草地早熟禾和高羊茅3种冷季型草坪草,分别按40g/m^2、20g/m^2和40g/m^2播种量在铺装式人造草上建植混合草坪,并对3种混合草坪坪用性状及其质量的综合评价。【结果】3种冷季型草种均适合建植混合草坪,综合评价结果表现为多年生黑麦草>高羊茅>草地早熟禾,多年生黑麦草建植的混合草坪质量最佳,其混合草成坪时间14d,试验结束时天然草密度为2.77枝/cm^2、总密度达4.72枝/cm^2,天然草盖度和总盖度均为100%,均一性6.89分,植株生物量为12.57g,加权分为8.04分。【结论】综合评价结果,认为多年生黑麦草为北方温带地区建植混合草坪的首选草种。【Objective】Paved natural-synthetic hybrid turf is a kind of newly developed hybrid turf in recent years.The synthetic grass of this hybrid turf is woven,and the natural grass is mostly planted by seeding.By comparing and evaluating the planting effect of perennial ryegrass,Kentucky bluegrass and tall fescue in paved natural-synthetic hybrid turf,the study was aimed to provide technical reference for the establishment of paved hybrid turf.【Method】The perennial ryegrass,kentucky bluegrass and tall fescue were planted on paved synthetic turf with seeding rates of 40 g/m^2,20 g/m^2 and 40 g/m^2 to establish hybrid turf.And the comprehensive evaluation of characteristics and quality of the three kinds of hybrid turfs were conducted.【Result】The results showed that the three cold season turfgrass are all suitable for the establishment of hybrid turfs.Based on comprehensive evaluation results,the fitness was ranked as perennial ryegrass>tall fescue>kentucky bluegrass,indicating that perennial ryegrass is the best one as natural turfgrass to be used for the establishment of hybrid turf with 14 d of turf establishment time and 2.77 shoots/cm^2 of natural grass density,4.72 shoots/cm^2 of total density,100%of both natural grass coverage and total coverage,6.89 points of uniformity score,12.57 g of plant biomass,and 8.04 points of weighted score at the end of the experiment.【Conclusion】According to the results of comprehensive evaluation,perennial ryegrass is the first choice for the establishment of hybrid turf in north temperate zone.
