经过无产阶级文化大革命和批林批孔运动,开门办科研,科技人员深入林区,组成以工人为主体的三结合试验小组,研制硫酸软膏和采割工艺,使单刀产脂量显著提高。马尾松软膏采脂比常法提高4-5倍,云南松软膏采脂提高6-8倍。持续流脂时间马尾松8-10天,云南松长达19-28天,劳动生产率进一步提高,为我国伐前采脂提供了新的工艺。目前,中国农林科学院林化所、江西崇义林场、四川普威林业局、广西桂林、玉林、湖南邵阳、四川林科所等单位都在积极开展硫酸软膏化学采脂试验研究工作。同时也开始逐步推
After the Great Proletarian Cultural Revolution and the Campaign for Criticizing and Approval of Boreal Forest, we opened a door for scientific research and scientific and technological personnel went deep into the forest to form a three-pronged experimental group with workers as the main body. We developed a sulfuric acid ointment and cutting technology to significantly increase fat production. Masson pine ointment taller than traditional methods to improve 4-5 times, Yunnan pine ointment to increase fat 6-8 times. Continuous flowering time Pinus massoniana 8-10 days, Yunnan pine up to 19-28 days, labor productivity further improved, for our country before cutting lipids provides a new process. At present, the institute of forestation of Chinese Academy of Agriculture and Forestry, Chongyi Forest Farm in Jiangxi Province, Preva Forestry Bureau in Sichuan Province, Guangxi Guilin, Yulin, Hunan Shaoyang, Sichuan Forestry Branch and other units are all actively carrying out experimental research on chemical grease extraction of sulfuric acid ointment. At the same time also began to push
