摘　　要：[目的]探究榆林市适宜种植的草坪草种。[方法]以草种球迷、御园、绅士、护坡高羊茅、代特斯、肯塔基、优美和剪股颖8个草种为试验材料,通过大田试验,测定不同草种的密度和盖度、茎粗与根长的变化、叶绿素的变化及其对土壤水热状况的影响。[结果]适合榆林市生长的草种依次为绅士、球迷、御园、护坡高羊茅、优特斯、肯塔基、优美、剪股颖。黑麦草球迷的土壤含水量高于其他草种7.1%~36.3%,黑麦草球迷的盖度高于其他草种43.5%~202.9%,黑麦草3个品种的地表温度高于其他草种,且与对照组相当,御园草坪草根冠比仅次于护坡高羊茅。[结论]黑麦草是榆林市适宜的草坪草种。[Objective]To explore suitable turf species for planting in Yulin area.[Method]Eight grass species,namely Lolium perenne L.‘Fans’,Lolium perenne L.‘Royal Garden’,Lolium perenne L.‘Esquire’,Festuca arundinaces Schreb,Festuca arundinaces Schreb‘Unitus’,Poa annua L.‘Kentucky’,Poa annua L.‘Graceful’and Agrostis matsumurae Hack.ex Honda,were used as test materials,the density and coverage of different grass species were measured,the change of stem diameter and root length,the change of chlorophyll and the influence of soil water and heat were measured.[Result]The suitable growth order in Yulin area is:Lolium perenne L.‘Esquire’,Lolium perenne L.‘Esquire’,Lolium perenne L.‘Royal Garden’,Festuca arundinaces Schreb,Festuca arundinaces Schreb‘Unitus’,Poa annua L.‘Kentucky’,Poa annua L.‘Graceful’,Agrostis matsumurae Hack.ex Honda.The soil moisture content of Lolium perenne L.‘Fans’was 7.1%-36.3%higher than that of other grass species,the coverage of Lolium perenne L.‘Fans’was 43.5%-202.9%higher than that of other grass species,and the ground surface temperature of Lolium perenne L.was higher than that of other grass species,the ratio of root to shoot of Lolium perenne L.‘Royal Garden’was second only to that of Festuca arundinaces Schreb.[Conclusion]Ryegrass is a good lawn grass in Yulin.
