油松(Pinus tabulaeformis)是我国北方广大地区最主要的造林树种之一。在我国松属中,油松的分布范围仅略小于马尾松,而占第二位。山西、陕西为其分布中心。据调查,我省拥有油松林496万亩,在省直林区中龄林以上的油松林150万亩,可供采脂的油松林约50万亩。油松具有工业采脂的价值,太岳林局近几年试生产的经济效益也是好的。油松采脂是综合利用油松资源,变资源优势为经济优势,对搞活林区经济,促进山区农民致富,为实现林业总产值翻两番都具有重要的意义。1983年,我们接受省科委下达《油松化学采脂的研究》课题,进行了三十烷醇采脂
Pinus tabulaeformis is one of the most important afforestation species in the vast areas of northern China. Pine in our country, Pinus tabulaeformis distributed only slightly smaller than Masson pine, which accounted for second place. Shanxi, Shaanxi for its distribution center. According to the survey, the province owns 496 million mu of Pinus tabulaeformis forest, 150 million mu of Pinus tabulaeformis forest of above middle-aged forest in Zhulin District, about 50 million mu of Pinus tabulaeformis forest for harvesting. Pine with the value of industrial grease, too Yuelin Bureau trial production in recent years, the economic benefits are good. Pine resin is the comprehensive utilization of Pinus tabulaeformis resources, change the advantages of resources for economic advantages, to revitalize the forest economy, promote mountain farmers get rich, in order to achieve quadrupling of total output value of forestry is of great significance. In 1983, we accepted the provincial Science and Technology Commission issued a “study on the pine oil chemical lipids,” the subject of triacontanol lipophilic
