我国松香主要是脂松香,脂松香产量完成的如何,取决于松脂的多少而定,因而采割松脂这项生产,已引起人们重视。就世界采脂来说,由三十年代的常法采脂逐步发展到七十年代的化学采脂,其目的是促进和延长松脂的分泌,从而提高侧沟或单位面积产脂量。我们认为,一棵松树在一个采脂季节里,要想提高它的产脂量,采用先进的采脂技术只是一个方面,更重要的是松树还得有适应先进采脂技术的制造松脂补充量;换句话说,也就是松树在单位时间内,制造松脂能力的大小问题。在采割间隔期内,松树制造松脂能力大时,侧沟产脂量就上升;反之产脂量就下降,这是采脂人员在生产中经常
China’s rosin is mainly gum rosin, rosin production completed, depending on how much rosin, and therefore the production of cutting rosin, has attracted people’s attention. In terms of the world’s fat-making, the gradual development of fat-collecting techniques from the 1930s to the chemical-fat-making in the 1970s aims at promoting and prolonging the secretion of rosins to increase the fat production in the side ditch or per unit area. We think that in order to increase the yield of a pine tree in a greasy season, the use of advanced greasing technology is only one aspect. More importantly, the pine trees have to be supplemented by the advanced greasing technology ; In other words, that is, the size of pine tree in the unit of time, the ability to manufacture rosin. During the cutting interval, pine resin manufacturing capacity of rosin, side ditch fat production increased; Conversely fat production decreased, which is the production of fat in the staff often
