发展速生杨树,已成为世界各国解决木材急需的捷径。我国为了迅速扭转缺材状况,不仅在北方大力发展杨树造林,近些年来,在南方也积极引种速生杨树。我们于1978年从南京林产工业学院引种黑杨派四个新品系试验栽植,现将初期生长量的测定结果报告于后。 Developing poplar poplar has become a much needed shortcut for all countries in the world to solve the problem of timber. In order to quickly reverse the shortage of materials, our country not only vigorously develops poplar trees in the north, but also actively introduces poplar trees in the south in recent years. We in 1978 from the Nanjing Institute of Forestry introduced Black Poplar sent four new plant test planted, now the initial growth measured results reported later.
