摘　　要：采用环境适应参数及坪用性评价指标对12种草坪草在南京地区建植过程中的品种特性,成坪质量及坪用性状进行了系统研究。研究结果表明供试的12个品种中,几种高羊茅品种、午夜草地早熟禾品种色泽青绿,生长速度快,盖度高,环境适应性强,成坪质量好,坪用性高,最适于在南京地区建坪。多年生黑麦草品种特性较好,比较适于建坪,匍匐翦股颖爱神特品种色泽浓绿,成坪质量良好,但越夏率低、坪用性较差;狗牙根品种抗病虫害能力及耐热性均较强,但越冬能力较差,青绿期短,坪用性较差;马蹄金、白三叶青绿期短、色泽淡、耐寒性差、坪用性较差,不适宜于南京地区建坪。Variety characters of 12 turf grasses were studied and turf performance were estimated by using environment adaptive parameter and parameter of turf performance in this paper. The results show that Festuca arundinacea and Poa pratensis were the most adaptive to Nanjing area,Lolium perenne was more adaptive to the area. Green period of the three grasses were longer and turf performance were better than the others. Poa pratensis adapted cold and drought sistance of Cynod to the area with higher heat resistence. Agrostis stolonifera was dark green,and got higher resistance,but it could not resist the high temperature in summer. Disease, insect and heat resostance of Cynon Dactylon were better,however,its overwintering rate was lower,green period was short and not suitable to be planted in this area. The turf performance of Trifolium repens and C. dactylon were the lowest and were not adaptive to Nanjing area.
