摘　　要：评价了丹麦４种１２品种冷季型草坪草在兰州市区的生境适应性和坪用性表现，并以当地常用品种为参照。适应性测定了越冬力、越夏力、抗病性和青绿期；坪用性测定了质地、密度、颜色、耐磨性和生长速度等。进行了数量化（采取５分制，由差到优分为１～５）单项评定和综合评定，综合评定分别计算了环境适应参数（ＥＡＰ）、绿地型坪用参数（ＴＰＰ１）和运动场型坪用参数（ＴＰＰ２）。结果表明，供试１２个品种，有５个品种表现出良好的环境适应性（ＥＡＰ≥３），且全部品种表现出良好的坪用性（ＴＰＰ１或ＴＰＰ２≥３），其中Ｃｏｎｎｉ早熟禾（ＥＡＰ＝５．０，ＴＰＰ１＝４．０，ＴＰＰ２＝４．１），Ｓｕｚｅｔｔｅ紫羊茅（ＥＡＰ＝４．０，ＴＰＰ１＝ＴＰＰ２＝３．９），Ｃｏｍｐａｃｔ早熟禾（ＥＡＰ＝３．２，ＴＰＰ１＝３．４，ＴＰＰ２＝４．２）和Ｎａｐｏｌｉ紫羊茅（ＥＡＰ＝３．２，ＴＰＰ１＝４．１，ＴＰＰ２＝４．０）４品种，无论是适应性还是坪用性均表现突出，而且明显优于当地常用品种。本试验讨论了草坪草引种的评价方法。Twelve varieties of 4 cool season turf grass species were introduced from DLF TRIFOLIUM Ltd. of Denmark and evaluation tests were conducted in Lanzhou, Gansu province, during 1996～1997, with local available varieties used as the control. Characters related to the environmental adaptability (EA) and the turf performance (TP) were measured. The characters for EA included winter hardness, summer hardness, green period and disease tolerance; while those of TP included texture, density, colour, wear tolerance and growth speed. A scheme of numerical value 1 to 5 were used for evaluating each of the characters based on the performance ability from poor to good. Three parameters, including EAP (EA parameter), TPP 1(green land TP parameter) and TPP 2(sport field TP parameter), were proposed and calculated respectively for comprehensive evaluation of EA or TP. The results indicated that there were 5 varieties which adapted well to the environment, and all varieties performed well for turf usage. Among them, Poa pratensis cv. Conni (EAP= 5.0, TPP 1=4.0, TPP 2=4.1), Festuca rubra cv. Suzette (EAP=4.0, TPP 1=TPP 2= 3.9), P. cv, Compact (EAP=3.2, TPP 1=3.4, TPP 2=4.2) and F. cv, Napoli (EAP= 3.2, TPP 1=4.1, TPP 2=4.0) not only adapted well to the environment, but also performed well for turf usage. These 4 varieties were superior to the control. The evaluation method for turf grass introduction was also discussed.
