摘要
针对造林树种单一、病虫危害严重的局面,巴彦淖尔市从1998年开始引进河北杨和国槐等56个新树种。通过育苗试验和区域造林试验,按照抗寒性分级,采取苗期选择、造林选择和综合选择的方法,筛选出河北杨、国槐、白蜡、三北1号杨、桧柏、丁香、连翘、卫矛、红叶小檗等9个树种,不仅为河套地区及其类似区域的农防林、用材林建设和城镇道路绿化提供了新树种和相应管理技术,而且为该地区的树种选择和引种管理提供了科学依据。

Through seedling raising experiment and regional afforestation experiment, 9 kinds of tree species have been chosen by use of seedling selection, afforestation selection and comprehensive selection according to grade of cold - resistance, such as Populus hopeiensis, Sophora japonica , Fraxinus chinensis , Three - North No. 1, Sabina chinensis , Syringa oblate, Forsytia suspense, Euonymus alatus , Berberis thunbergii.
