松香是我国重要的一项林付产品,也是工业部门生产所必需的重要化工原料之一,但云南林区松香生产的产量却很低,未能充分地利用现有的松林资沅。为了有效的发挥其潜力,以满足社会主义建设迅速发展的需要,对松香生产潜力,进行了初步探讨。一、可供采脂树种资沅分布概况: 我省森林资沅丰富,是我国主要林区之一,按树种来讲,以针叶树种为主,总蓄积量为5.86亿立方米,在针叶树种中云南松又占绝大比重,其蓄积量为2.8676亿立方米,占全省有林地总蓄积量的31％,思茅松次之,有1.00亿立方米,占全省
Rosin is one of the most important forest-paid products in China. It is also one of the important chemical raw materials necessary for industrial production. However, the yield of rosin in Yunnan’s forest areas is very low, and the existing pine forest resources are not fully utilized. In order to effectively develop its potential and meet the needs of the rapid development of socialist construction, the potential of rosin production has been discussed. First, available for the distribution of resin species Yuan general situation: rich in forest resources in our province, is one of China’s major forest areas, according to tree species, mainly coniferous species, the total volume of 586 million cubic meters, in the conifer species Yunnan pine accounted for the vast majority, the volume of 2.8676 trillion cubic meters, accounting for 31% of the province’s total volume of woodland, Simao Song, followed by 100 million cubic meters, accounting for the province
