化学除草是多快好省地消灭田间杂草的一项重要措施,在林业生产上更有其突出的作用。自六十年代以来,国外应用化学除草的国家日益增多。我省有些单位过去由于对化学除草剂性能和除草原理学习不够,多不敢大胆使用。自1974年以来,我省开展了这方面的科技协作,四年来,在各级领导的关怀和支持下,各协作单位积极开展试验、示范工作,取得了较显著的成绩。试验的药剂达20多种,试验对象既有阔叶苗,也有针叶苗;有扦插苗,也有播种苗;有苗圃,也有果园。协作单位由8个发展到33个,其中有国营场圆,也有社队林场。试验方法由施用单一药剂发展到多种药剂混合试验。1977年的试验、示范面积已达500余亩。为了进一步在全省推广这项新技术,促使苗木优质高产,并逐步把除草剂应用到荒山造林方面,为“绿化祖国”做出更大贡献,特选刊了《苗圃化学除草剂试验报告》和《化学除草剂简介》两文,供各地参考。 Chemical weeding is an important measure to exterminate weeds in the field more efficiently and economically, and it plays an even more prominent role in forestry production. Since the 1960s, the number of countries applying chemical weed control has been increasing. Some units in our province in the past due to the performance of chemical herbicides and weeding the lack of learning, more than bold use. Since 1974, our province has carried out scientific and technological cooperation in this field. Over the past four years, with the care and support of leaders at all levels, various collaborators actively conducted experiments and demonstrations and achieved remarkable achievements. Test of up to 20 kinds of agents, the test object both broad-leaved seedlings, there are also coniferous seedlings; cutting seedlings, but also sowing seedlings; nursery, but also orchards. Collaboration units developed from 8 to 33, of which there are rounds of state-owned parks and community-owned forest farms. Test methods developed from the application of a single agent to a variety of pharmaceutical mixing test. 1977 test, demonstration area has reached 500 acres. In order to further promote this new technology in the province, prompting seedlings of high quality and high yield, and gradually applied herbicides to the afforestation of barren hills, to make greater contribution to “greening the motherland”, the special issue of “Nursery Chemical Herbicide Test Report” and “Introduction to Chemical Herbicides” two articles for reference throughout.
