化学除草在林业生产各环节中起着重要作用,是林业生产中一项行之有效的新技术。为了更快地在林业生产中推广、应用化学除草技术,中国林科院林研所与沈阳化工研究院于1984年9月15-19日在黑龙江省牡丹江市召开了全国第二次林业化学除草技术座谈会。参加会议的代表有来自全国21个省、区(市) 69个林业、农垦、化工部门的领导、科技工作者共79名。会议期间,代表们回顾了自全国第一次林业化学除草技术座谈会以来,林、园化学除草所取得的进展。在这三 Chemical weeding plays an important role in all aspects of forestry production and is an effective new technology in forestry production. In order to more quickly promote the forestry production, the application of chemical weeding technology, Chinese Academy of Forestry Institute and Shenyang Institute of Chemical Research in 1984 September 15-19 in Mudanjiang City, Heilongjiang Province held a second national chemical weed control Technical Symposium. Delegates attending the conference included 79 leaders, scientists and technicians from 69 forestry, land reclamation and chemical industries in 21 provinces, districts and cities across the country. During the meeting, the delegates reviewed the progress made in chemical weeding in forests and parks since the first Symposium on Weeding Technology in Forestry in China. In these three
