为适应当前社会的发展,主动解决工业用材资源的缺乏,从1985年开始与洞庭湖区12个县(市)、2个农场建立杨木胶合板材基地。引种的欧美黑杨Ⅰ-63、69、72无性系表现成材早、轮伐期短的特点。现营造基地林133km~2,已取得社会、经济效益。目前基地建设存在经济水平低,难以达到定向培育目的;不合理的体制制约了基地发展;资金短缺,近期与长远利益不同步。通过杨木应用开发研究表明,制胶合板、刨花板均符合国家标准;用杨木制纸浆得浆率高达9O％以上,质量符合国家标准,其树皮、树叶和树汁经加工后利用广泛,价值较高。
In order to adapt to the current social development, take the initiative to solve the lack of industrial timber resources, since 1985 and Dongting Lake District 12 counties (cities), two farms to establish poplar plywood base. Introduction of the European black poplar I-63,69,72 clones show the benefits of early, short rotation characteristics. Is to create a base forest 133km ~ 2, has made social and economic benefits. At present, there is a low level of economic development in the base construction and it is difficult to achieve the goal of directional cultivation. The unreasonable system restricts the development of the base. The shortage of funds has not synchronized the long-term and short-term interests. Through the poplar application development research shows that plywood, particleboard are in line with national standards; with poplar pulp rate was as high as 9O%, quality in line with national standards, the bark, leaves and sap processed widely used, the value Higher.
