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。
The habitat adaptability and plowing performance of four Danish 12 cold-season turfgrass species in Lanzhou were evaluated, and the reference was made to the commonly used varieties in Denmark. The overwintering force, the summer force, the disease resistance and the green period were determined by adaptability. The texture, density, color, abrasion resistance and growth rate were determined. (EAP, green TPP1) and sports ground ping-pong (green ground-based ping pong) were calculated according to the individual assessment and comprehensive assessment. With parameter (TPP2). The results showed that 5 of the 12 tested cultivars showed good environmental adaptability (EAP≥3), and all cultivars showed good flattability (TPP1 or TPP2≥3). Among them, EAP = 5.0, TPP1 = 4.0, TPP2 = 4.1), Suzette blue fescue (EAP = 4.0, TPP1 = TPP2 = 3.9) 3.4, TPP2 = 4.2) and Napoli fescue (EAP = 3.2, TPP1 = 4.1, TPP2 = 4.0) Significantly better than the local varieties commonly used. The test discussed the introduction of turfgrass evaluation method.
