长春地区美国红枫引种及嫩枝扦插研究

Study on the Introduction and Tender Cuttings of American Red Maple in Changchun

为丰富长春地区彩叶树种,培育适应性强,能露地越冬的彩叶树品种。从大连引种美国红枫秋火焰并进行嫩枝扦插试验。结果表明,北美红枫引种长春,生长良好,冬季可露地越冬,夏季未发生萎蔫、焦边等现象,可安全越夏;引种后光肩星天牛危害较重。在引种驯化过程中,越冬防寒和光肩星天牛的防治是树木成活的关键。

In order to enrich the colorful leaf tree species in Changchun area, cultivate the varieties of colorful leaf tree which have strong adaptability and can overwinter in the open. The autumn flame of red maple was introduced from Dalian and the experiment of twig cutting was carried out. The results showed that the introduction of red maple in Changchun had a good growth, and it could survive in the open in winter, without wilting and scorching in summer, and it could safely survive in summer. In the process of introduction and domestication, overwintering and cold prevention and control of Anoplophora glabripennis are the key to the survival of trees.
