为加强次生林经营工作,改变低产劣质面貌,我们从六十年代开始进行这项研究。1975年由抚顺市林科所与二个国营林场和一个集体林场协作,搞了3881亩的综合经营技术试验。结果表明:集中连片;按一沟一坡的经营顺序,并按可留优良木数量多少划分经营类型,坚持“五砍五留”的选木原则,在采伐迹地上见缝插针补栽针(阔)叶树,诱导针阔混交林的综合经营技术,是多快好省培育次生林的有效措施。该项技术已在生产中推广应用,1982年共推广5万亩.
In order to strengthen the work of secondary forest management and to change the appearance of low-yielding and inferior quality, we started the study in the 1960s. In 1975, Fushun Linke Institute cooperated with two state-owned forest farms and a collective forest farms to engage in 3881 mu of integrated management technology trials. The results showed that: the concentration of contiguous; according to a ditch slope of the business order, and according to the number of good wood can be divided into more types of management, adhere to the “five cut five stay” principle of selection of wood, ) Ye Shu, inducing integrated management techniques of coniferous and broad-leaved mixed forest, is an effective measure to cultivate secondary forest in more fast and good province. The technology has been applied in production, in 1982 a total of 50000 acres of promotion.
