摘　　要：在成都对高羊茅等 2 6个国外冷季型草坪草品种进行了为期 3a的引种适应性评价研究 ,结果表明 :(1) 11个参试的高羊茅品种和 2个白三叶品种、2个剪股颖品种都表现出较好的适应性和抗逆性 ,其中高羊茅以Barfa、Vegas表现最优、剪股颖以Prominent最优、白三叶以Tahara最好 ;(2 )高羊茅冬季有叶尖发黄现象 ,部分品种夏季有褐斑病 ;(3)紫羊茅、羊茅、硬羊茅等 11个细叶类品种 ,抗热性较差 ,越夏率 <50 % ,基本不适应 ,但冬春表现好 。The adaptation studies on 26 varieties of turfgrass from abroad were carried out in Chendu for 3 years. The result shows: 11 varieties of Tall Fescue (Festuca arundinacea), 2 varieties of White Clover (Trifolium repens) and 2 varieties of Bentgrass (Agrostis) possess better adaptability and resistance than other varieties. In Tall Fescue, Barfa and Vegas are the best varieties, in Bentgrass, Prominent is the best and in White Clover, Tahara is the best. The leaf tips of Tall Fescue will turn yellow and red spot disease will appear on some varieties of this grass in summer. 11 varieties with thin leaves such as Red Fescue, Fescue and Rough Fescue have poor heat resistance and their over summering rates are less than 50%. These varieties are basically not adaptable to this environment, but their performance in winter and spring are quite good, they are the ideal grass to reseed the warm-season turf.
