本世纪七十年代,松香生产发展速度比较平稳,各年度之间的产量升降幅度不大,年平均产量为25万吨,最高年产量29.8万吨,平均年增长率为5.8％。到了七十年代末期,松香和松节油都供不应求,保证不了国内和出口的需要。进入八十年代后,农村普遍推广了生产责任制,劳力有了富余,上山采松脂的劳力增多,松香生产发展很快,产量大幅度增加,一九八○年和一九八一年,松香产量超过了30万吨和40万吨。与此同时,松香和松节油的出口有所减少。松香八十年代头两年的平均
In the 1970s, the production of rosin grew at a relatively steady pace, with little increase in output between years. The average annual output was 250,000 tons, and the highest annual output was 298,000 tons, with an average annual growth rate of 5.8%. By the end of the 1970s, both rosin and turpentine were in short supply and could not guarantee domestic and export needs. After entering the 1980s, rural areas generally promoted a system of production responsibility. Labor has been spared. The labor force for picking up the pines has increased, and the production of rosin has developed rapidly. The output has increased dramatically. In 1980 and 1981, rosin was introduced. The output exceeded 300,000 tons and 400,000 tons. At the same time, exports of rosin and turpentine have decreased. The average of Rosin in the first two years of the 1980s
