摘　　要：对四种草坪草种子进行了萌发特性测定及预萌发和镇压对建坪影响。结果表明 :四种草坪草幼苗的生活力强弱依次为意大利黑麦草 >紫羊茅 >高狐茅 >亨特草地早熟禾 ;预萌发与直播在出苗率、生物量和枝条数上都表现出显著差异 (P≤ 0 .0 5 ) ,镇压与不镇压差异不显著 (P≥ 0 .0 5 )。采用预萌发技术建植草坪有利于提高建坪速度和建坪质量。From study of germinated characteristics,per-germination and pressing in four kinds of turfgrass Seeds,the results showed that activity of seedling was ALomium multiforum,Festuca rubra,Festuca arundinacea,poa pratensis L.cv.Huntsvlle.It was obviously different between pre-germination and sowing in seedling emergance rates,biomass and number of branches.It was not different between pressing and unpressing.Technic of pre-germination was better for increasing speed of turfgrass establishment and quality of turfgrass.
