我县位于山东省东南部,发展杨树生产有得天独厚条件。自1976年以来引进许多速生类杨树品种,营造小片杨树速生丰产林,到1985年全县已发展到10.07万亩,遍及32处乡镇,551个村庄。由于实行集约经营,林木生长快,每年亩均生长量达1.5立方米,全县杨树丰产林的总蓄积达到33万立方米。此外,农田林网中的杨树折实面积有4万余亩;四旁树木中有杨树288万株,折实面积也近2.9万亩,总计全县有杨树约17万亩。如何把这一资源充分的利用起来并纳入商品经济的轨道,向外型经济发展,很有探讨价值,也是当前亟待解决的问题。我们从两方面进行探讨。
My county is located in southeastern Shandong Province, the development of poplar production has unique conditions. Since 1976, many species of poplar poplar have been introduced to create small-piece poplar fast-growing and high-yield forests. By 1985, the county had grown to 10.07 million mu and covered 551 villages and 32 townships. As a result of intensive management, rapid growth of trees, the annual growth of mu reached 1.5 cubic meters, the county poplar total yield reached 330,000 cubic meters. In addition, the poplar field in farmland has a net area of more than 40,000 mu; there are 2.88 million poplar trees in the four sides of the tree, with a real area of nearly 2.9 million mu. In total, there are about 170,000 mu of poplar in the county. How to make full use of this resource and bring it into the track of commodity economy and develop the outward-looking economy has great value to explore and is also an issue to be solved urgently. We explore from two aspects.
