【摘要】 [目的]比较8个品种草坪草在甘肃景泰地区的适应性和坪用性,为草坪草的利用提供依据。[方法]2002~2004年测定了各品种的抗寒性、抗热性、抗病性、青绿期、密度、盖度、质地、绿度,并进行了单项评定和综合评定。[结果]供试的8个品种中有7个品种表现出良好的环境适应性。其中,Dornie、Opal、Haga、Eva、Sobra 5个草地早熟禾品种综合评定达到7,Lovisa细羊茅、Slalom硬羊茅的综合评定达到8的适宜水平。Ronja多年生黑麦草不能越冬。[结论]Lovisa细羊茅、Slalom硬羊茅的综合性能优于Dornie、Opal、Haga、Eva 4个草地早熟禾品种,但他们均适宜在甘肃地区利用。更多还原

【Abstract】 [Objective] Eight varieties of turfgrass were introduced and the evaluation tests were conducted to provide references for the utilization in Jingtai area,Gansu Province.[Method] Characters related to the environmental adaptability and the turf performance were measured by single entry and synthetic evaluation during 2002-2004.The characters included winter hardness,summer hardness,disease tolerance,green period,density,coverage,texture,and color.[Result] The results indicated that there were 7 varieties which adapted well to the environment.Thereinto,the synthetic evaluation of Poa pratensis cv.Dornie,Poa pratensis cv.Opal,Poa pratensis cv.Haga,Poa pratensis cv.Eva,Poa pratensis cv.Sobra reached 7,and Festuca rubra cv.Lovisa and Festuca brevipilia cv.Slalom reached 8.They all reached the suitable level.Lolium perenne cv.Ronja wasn’t overwintering.[Conclusion] The synthetic evaluation of Festuca rubra cv.Lovisa and Festuca brevipilia cv.Slalom were superior to Poa pratensis cv.Dornie,Poa pratensis cv.Opal,Poa pratensis cv.Haga,Poa pratensis cv.Eva.All of them were suitable to utilize in Jingtai area,Gansu Province.更多还原
