摘要
通过在佳木斯引种火炬树、花楸、金叶榆等彩叶树种,并对各树种进行生长期观察和抗寒性等级分析。结明表明:花楸、金叶榆耐寒,在佳木斯气候条件下不需防护措施,可安全越冬;火炬树对佳木斯冬季气候适应能力较差。
Colorful trees including rhus typhina, sorbus and gold leaf elm were inti＇odueed. Each species were observed in growth period and level of cold resistance were analysed. The results showed that sorbus and gold leaf elm don＇t need protective measures in Jiamusi climate conditions in winter because of cold-resistant, while ability to adapt of rhus typhina in winter was poor.
