北美复叶槭又名羽叶槭、糖槭,属槭树科落叶乔木,原生北美洲,成年树高15～20米。国家林业局“948”项目重点引进推广优良用材林树种之一。于1998年从美国和加拿大交界区域选取种源,2003年在山东、黑龙江等地推广成功。2010年春,国营江苏省东海县海陵林场从山东引进1000多株北美复叶槭进行繁育试验,目前已全部存活,平均树高3.7米,最高达5.2米。引种繁育试验结果表明,北美复叶槭耐旱耐涝、抗风力强、耐盐碱、病虫害少,适应性很强。一、生物学特性喜光,耐庇阴,喜温暖、湿润气候且耐寒冷,可耐绝对低温-45℃;喜湿润、肥沃土壤,又耐干旱瘠薄;适应性强,全国大部 North America Acer palmatum, also known as maple leaf maple, sugar maple, is a maple Branch deciduous tree, native North America, adult tree height 15 to 20 meters. State Forestry Administration “948 ” project focuses on the introduction of one of the excellent timber forest species. In 1998, the provenance was selected from the junction of the United States and Canada. In 2003, it was successfully popularized in Shandong and Heilongjiang provinces. In the spring of 2010, the state-run Hailin Forest Farm in Donghai County, Jiangsu Province, introduced more than 1,000 North American compound leaf maples from Shandong for breeding tests and has now survived with an average height of 3.7 meters and a maximum of 5.2 meters. The introduction and breeding test results show that the maple leaf of North America drought tolerance, wind resistance, salt and alkali resistance, fewer pests and diseases, adaptability. First, the biological characteristics Hi light, shade Yin, hi warm, humid climate and cold-resistant, resistant to absolute low temperature -45 ℃; hi wet, fertile soil, but also resistant to drought infertility; adaptability, most of the country
