摘　　要：通过对栽培了2年的高羊茅、草地早熟禾和多年生黑麦草三大品系20个草坪草品种的土壤进行土壤硬度、土壤容重、饱和持水量、毛管持水量、非毛管孔隙、毛管孔隙和总孔隙度等指标的测定,比较它们对土壤物理性状的影响。结果表明:对土壤物理性状影响较大的品种有沙漠王子、阿米高、新歌来德、美洲王、优异、巴林、康尼、萨卡特、爱神特;3个品系之间,影响最大的为草地早熟禾。Twenty coldseason turfgrass varieties from three species, namely, Festuca arundinacea, Poa pratensis, and Lolium perenne, were planted Physical indices of the soil including soil hardness, soil bulk density, water retention capacity etc were measured, and the effects on soil physical characteristics between turfgrass varieties compared Varieties showing the best influence on soil physical characteristics included Amigo, Nuglade, America, Merit, Balin, Conni, Sakini, and Accent Of the three species, Kentucky bluegrass showed the best influence The results provided some useful information about variety selection in areas similar to the experimental locations
