摘要
对多年生黑麦草、高羊茅、早熟禾、紫羊茅等10个草坪草种的36个品种,在兰州进行引种抗寒性研究。初步结果表明:绿期最长,几乎无绝对枯黄期的品种是草地早熟禾的百赞,紫羊茅的百琪和硬羊茅的百妃娜,其次为紫羊茅的百绿(328 d),百丽佳(326)和皇冠(318天);越冬存活率最高的品种是多年生黑麦草的首相(136％);返青后再生力最强的品种是紫羊茅的百琪、百牛和多年生黑麦草的首相,返青1月后的草层高度和地上生物量分别为23.1cm和248g/m^2、19.2 cm和234g/m^2、19.3cm和231g/m^2;综合抗寒越冬性最好的是紫羊茅的百绿和百琪、硬羊茅的百妃娜和多年生黑麦草的首相(皆为8.2),早熟禾以百赞最高(8.0),高羊茅以维加斯(7.6)较好。
Cold-tolerances of 36 varieties within 10 species of turfgrass introduced in Lanzhou are evaluated. The results show that BARZAN Kentucky bluegrass, BARFINA F. ovina D. , BARGENA F. rubra L. are ever-green varieties. PREMIER L. perenne L. shows great winter survival rate, regarding spring regrowth, PREMIER L. perenne L. , BAROXI and BARGENA F. rubra L. have excellent capability both in height and above-ground biomass. BAR-OXI and BARGREEN F. rubra L. , BARFINA F. ovina D. , PREMIER L perenne L. and VEGAS F. arundinacea L. are the suitable for the establishment of greenland in Lanzhou due to their distinguishing features of fast regrowth and comprehensive cold-tolerance.
