美国红枫“秋火焰”在铁岭地区的引种表现及嫩枝扦插繁育技术研究

Study on the introduction performance of “autumn flame” of Acer rubrum L. in Tieling area and its twig cutting propagation technology

在铁岭地区引进美国红枫“秋火焰”进行栽培试验,对其越冬表现、物候期表现、历年生长量、低温适应性等方面进行了观测,并总结出了越冬管理办法。开展了扦插繁育技术研究,总结出了嫩枝扦插繁育方法,扦插成活率达90%以上。结果表明,美国红枫“秋火焰”适合在铁岭地区栽培应用,同时适宜向铁岭以北、黑龙江哈尔滨以南地区推广,是兼顾绿化与美化作用的优势园林树种。

In Tieling area,the“autumn flame”of Acer rubrum L.was introduced to carry out cultivation experiments.The overwintering performance,phenology performance,annual growth,low temperature adaptability and other aspects were observed,and the overwintering management methods were summarized.The research on cutting propagation technology was carried out,and the method of twig cutting propagation was summarized.The survival rate of cutting reached more than 90%.The results showed that Acer rubrum L.“autumn flame”is suitable for cultivation and application in Tieling area,and it is suitable for promotion to the north of Tieling and the south of Harbin,Heilongjiang Province.It is a dominant landscape tree species that takes both greening and beautification into account.
