高羊茅和狗牙根草坪草品种在重庆地区的引种试验

Introduction of tall fescue and Bermudagrass turfgrass varieties to the Chongqing region

引自百绿集团的6个草坪草品种,在重庆地区进行2年的坪用性状评价。结果表明,供试品种在该地区均可终年生长。5个高羊茅品种中以Vegas表现最好,叶色浓绿,生长速度适中,盖度居供试品种之首,对该区高温高湿和高温干旱2个越夏因子均可适应;其次为Barlexas。狗牙根BarCd8USAI耐高温干旱,抗病性强,茎细叶窄,但叶色偏淡,冬季停止生长早,早春生长速度缓慢。

Six varieties of turfgrasses from the Barenbrug Group were evaluated during 1999-2000 in Chongqing. The results showed that all tested varieties could grow in this region. Festuca arundinacea Vegas performed the best out of five F. arundinacea varieties. Its advantages included greener leaf, moderate growing speed, and the highest coverage. It was adaptable to the two local climatic conditions of high temperature with high humidity and high temperature with drought. The second best variety was F. arundinacea Barlexas. Cynodon dactylon BarCd8USAI was able to endure high temperature with drought, had strong disease resistance, and had thin stalks and narrow leaves. However, its color was too light, it stopped growing early in winter, and grew slowly in early spring.
