我大队有林地三千亩,其中赤松林二千亩,树令一般在十八年生左右,大部分是次生林。过去由于管理不善,虫害蔓延,修枝过重,伐优留劣,造成疏密不匀,林分质量较差。为培育好现有松林,尽快提供优质木材,我们从1973年春开始搞扶育间伐试验,1975年春逐步把试验成果用于生产,取得较好的效果。实践证明,合理进行扶育间伐是改造低产林分、促进林木速生丰产的一项重要技术措施。 My brigade has three thousand acres of forest land, of which two thousand acres of red pine, tree orders generally about eighteen years, most of the secondary forest. In the past due to poor management, insect infestation, pruning too heavy, poor quality control, resulting in uneven density, poor quality of the stands. In order to cultivate the existing pine forest and provide high-quality timber as soon as possible, we started the fertility thinning test from the spring of 1973, and gradually applied the test results to the production in the spring of 1975, achieving good results. Practice has proved that it is an important technical measure to rebuild low-yield stands and promote fast-growing and high-yielding forests by reasonably carrying out thinning for rest and recuperation.
