北京地区57个冷季型禾草草坪品种的生态适应性评价

在北京市顺义区克劳沃试验基地,通过不同品种高羊茅(Festuca arundinacea)、紫羊茅(F.aubra)、硬羊茅(F.ovinavar.durivscula)、草地早熟禾(Poa pratensis)和多年生黑麦草(Lolium perenne)各草坪特性指标定量测定,对各草坪草品种的生态适应性进行综合评价。结果表明:不同草坪草种的综合生态适应性多年生黑麦草最好,高羊茅次之,紫羊茅和草地早熟禾中等,硬羊茅较差。多年生黑麦草各品种的综合生态适应性以Protegeglr和Laquinta最好,Fairway最差;高羊茅各品种以Rhamldersrp、Traversersrp和Hum-mer综合表现最好,Ruby最差;紫羊茅邱氏羊茅表现最好;硬羊茅Ecostar最好;草地早熟禾则以Rush最好,Camask最差。综合比较认为,在北京地区建植草坪,多年生黑麦草适宜作先锋种或补播草种,高羊茅适宜作运动场或开放地草坪建植,草地早熟禾适宜观赏性草坪建植。

Adaptability evaluation of 57 cool season turfgrass varieties in Beijing region

The density, texture, colour, persistence, coverage, disease resistance, heat hardiness and recuperative potential of 57 cool season turfgrass varieties of Festuca arundinacea, F. aubra, F. Ovina var. durivscula, Poa pratensis and Lolium perenne were measured and their performance and ecological adaptability in Beijing region were evaluated as well. The result showed that the ecological adaptability of L. perenne was the best, F. arundinacea ranked the second, F. aubra and F. ovina var. durivscula was the last. The performance and the ecological adaptability of Protegeglr and Laquinta from L. perenne was the best, Qiudao was the last; while for F. arundinacea, Rhamldersrp, Traversersrp and Hanma were the best and Hongbaoshi was the poorest, and Qiushiyangmao from F. aubra and Ecostar from F. ovina var. durivscula ranked the first. For P. pratensis, Rush was the first and Camask was the last. It could be concluded that L. perenne was proper for pre seeding and overseeding, F. arundinacea for playfield and P. pratensis for park lawn.
