采脂是松树立木综合利用的好途径。我省油松立木采脂近年已在太岳林局灵空山等林场试点,并取得较好的经济效益。根据油松的产脂力一株油松采脂十年,其采脂所得产值要超过木材本身的产值。因此,油松采脂生产为实现我省林业产值翻番提供一项投资少、经济效益较好的生产项目,目前已引起重视和推广。现将油松采脂工艺简要介绍如下:一、常法采脂的基本方法1.下降式采脂:在刮好的刮面上先开中沟,第一对侧沟开在刮面的顶部,第二对侧
Adipose is a good way to comprehensively utilize pine trees. In recent years, our province pine tree wood liposuction in Taiyuan Forest Bureau Lingkang Shan other forest pilot projects, and achieved good economic returns. According to the production of pine a fat pine oil production for ten years, the output value of its oil extraction to exceed the output value of wood itself. Therefore, the production of Pinus tabulaeformis in order to achieve double the output value of forestry in our province to provide a less investment, better economic efficiency of production projects, has attracted attention and promotion. Now Pinus tabaci lipase process is briefly described as follows: First, the basic method of fat-picking 1. Drop-fat: scraping the scraping surface to open the first in the ditch, the first pair of side ditch open at the top of the scraping surface , The second opposite side
