根据苏联采脂资源及利用情况,为了迅速提高松脂产量,以满足工业对松香日益增长的需要,在改进采脂方法的同时,必须积极开辟新的松脂资源(如云杉、红松和落叶松)。落叶松在采脂方面具有极大的潜力。苏联有27420万公顷落叶松资源,而已开展采脂的欧州松才只有10950万公顷,即落叶松资源比欧州松资源还 In order to rapidly increase the yield of rosin to meet the growing demand of rosin in the industry, it is necessary to actively develop new rosin resources (such as spruce, Korean pine and larch ). Larch has a great potential for lipids. The Soviet Union has 274.2 million hectares of larch resources, and has only carried out the fat harvest of only 33.5 million hectares of European pine, that larch resources are also better than the state loose resources
