摘要
以7个红花槭品种为研究材料,从物候期、植株生长量、耐热性、耐寒性及抗病虫害能力5个方面,研究了7个红花槭品种在北京地区的生态适应性,并对其作出了综合评价。结果表明:‘仙娜格林’、‘索美赛’、‘酒红’、‘红点’、‘十月光辉’5个品种适应性最强。‘北林’次之,‘太阳谷’抽条较严重,适应性较差,不适于在北京地区栽培。‘索美赛’、‘红点’、‘酒红’、‘十月光辉’秋色叶观赏期最长可达30 d,观赏效果好于其他品种。
The ecological adaptation of seven species and cuhivars of Acer rubrum in Beijing in phonology, growth incre- ment, heat resistance, the ability to resist pests and diseases, and cold resistance was studied and evaluated in this paper. The results indicated that A. rubrum ＇ Sienna Glen＇ , A. rubrum ＇ Somerset＇ , A. rubrurn ＇ Brandywine＇ , A. rubrum ＇ Red Pointe＇ , A. rubrum ＇ October Glory＇ exhibited the best ecological adaptability in Beijing, the adaptability of A. rubrum ＇ Northwood＇ was in medium, A. rubrum ＇ Sun Valley＇ was the poorest. The ornamental period of autumn leaf color of A. rubrum ＇ Somerset＇ , A. rubrum ＇ Brandywine＇ , A. rubrum ＇ Red Pointe＇ and A. rubrum ＇ October Glory＇ were 30 d. Ornamental effect of this species and their cuhivars were better than that of the other species and cuhivars.
