大规模的试验研究表明,用百草枯(一种接触性除草剂,有效成份为1,1’—二甲基—4,4’—联吡啶阳离子盐——译注)处理松树是增加活松树的松香松节油含量的一种十分有效的方法,这种新技术为成倍成倍地增加世界松香松节油产品的产量提供了可能。美国赫格莱斯公司最近宣布,该公司的充脂工艺(百草枯处理松根,生产富含松脂的松树根株的工艺)进展顺利;但是,尽管有巨大的利润的潜力,迄今为止,还没有 Large-scale experimental studies have shown that the treatment of pine with paraquat (a contact herbicide, the active ingredient is 1,1’-dimethyl-4,4’-bipyridyl cation salt) is to increase the living pine Rosin turpentine content of a very effective method, this new technology is doubled to increase the yield of rosin turpentine products in the world may provide the possibility. The US company Hedge Inc. recently announced that the company’s greasing process (paraquat-treated pine needles, production of pine-root-rich pine roots) is progressing well; however, to date, there is not yet a huge profit potential
