草坪草利用及引种适应性研究

国外草坪草种在我国的引种评价结果表明:冷季型草坪草中抗寒性强的草种或品种,如紫羊茅、草地早熟禾、匍匐翦股颖的一些品种适宜于青藏高原、寒冷半干旱、寒冷潮湿、寒冷干旱带;抗热性强的冷季型品种,如高羊茅、草地早熟禾中的一些品种,耐低温的暖季型草种或品种,如狗牙根、杂交狗牙根、马尼拉、结缕草适宜于南、北过渡带;云贵高原带和温暖潮湿带适宜于大多数冷季型和暖季型草坪草生长发育;在热带、亚热带冷季型草基本不能适应,而多数暖季型草坪草适应性良好。

Review of research work on application and adaptability of introduced turfgrass

The results of tests on adaptability of introduced turfgrasses showed that better cold-resistant species and varieties of cool-season turfgrasses, such as red fescue, Kentucky bluegrass, creeping bentgrass, were adaptive for turf establishment in Qinghai-Tibetan plateau, cool-semiarid, cool-humid and cool-arid areas. Better heat-resistant varieties of cool-season turfgrasses, such as tall fescue, Kentucky bluegrass, or warm-season turfgrasses that could survive at low temperature, such as bermuda, Tifton, manilagrass, should be chosen in the South and North transition zone. Most of cool-season and warm-season turfgrasses could grow well in Yungui plateau and wram-humid areas. All cool-season turfgrasses could hardly survive, while most of warm-season turfgrasses could be used in tropical and sub-tropical areas.
