摘　　要：该文对国外优良草坪草在我国亚热带地区 (广州 )的适应性进行了研究 .结果表明 :美国引进的狗牙根品种Mirage ,Pyramid ,J61BG2 79和Del.Sol在广州具有良好的适应性和坪用价值 ,具有较强的抗寒性 ;其中Mirage和J61BG2 79可用于建植高级的运动场草坪 .所有高羊茅品种虽在广州地区越夏困难 ,但冬春季表现优良 .法国的高羊茅Amalia的表现最好 ,其次是丹麦的Cochise和荷兰的Vegas ,Barleduc ,而丹麦的DP795 2和荷兰的Barfelix ,Bar bizon ,Barlexus则表现一般 .由于高羊茅在冬春季生长良好 ,坪用性状较优 ,可以考虑用优良的高羊茅的一些品种进行南方草坪的冬季补播 ,或用在公路和城市绿化等方面 .试验还表明 ,在广州地区夏末秋初进行草坪草的播种既有利于狗牙根的快速成坪 。The adaptability of some exotic turfgrass varieties in sub\|tropical zone(Guangzhou) was studied. The results indicated that American bentgrass varieties of Mirage, Pyramid, J61BG279 and Del.Sol had a good adaptability and lawn value with cold resistance, particularly for Mirage and J61BG279 which were suitable to establish the upper class sport turf. All tall fescues performed well both in spring and winter but over\|summering hardly. The performance grades of tall fescue were, Amalia from France excellent, Cochise from Denmark and Vegas from Holland good, DP7952 from Denmark and Barefelix, Barbizon, Barlexus from Holland fair. It is suggested that some tall fescues varieties could be oversown in winter in the south China or used as highway and urban's green fields. The results also showed that sowing in late summer and early autumn had benefits both on Bermudagrass lawn quickly establishing and tall fescue lawn easily over\|summering in the coming year.
