目前,人们对于树木的利用已由单纯的木材逐渐转变为全树利用,国外的造纸原料也已由草类转为乔木。我国的造纸原料现仍以草类为主,远远满足不了造纸工艺和数量上的要求。要改变我国造纸原料的结构,必须探讨营造造纸工艺林的方法,为此我们于1978年在河北省邯郸地区漳河林场进行了沙兰杨短轮伐期人工林密植试验。现将试验初步结果报道如下: At present, people have gradually changed the use of trees from pure wood to full-tree use, and foreign paper-making raw materials have also been converted from grasses to trees. China’s papermaking raw materials are still mainly grass-based, far from meeting the papermaking process and the number of requirements. To change the structure of China’s papermaking raw materials, we must explore ways to create paper-making forest, so we in 1978 in Zhanghe, Handan, Hebei Province, a short rotation of the plantation rotation plantation planting experiments. Now the preliminary results of the trial are reported as follows:
