林业育苗应用化学除草是实现林业苗圃作业机械化、系列化,减轻劳动强度,降低育苗成本,提高苗木质量的有效技术措施。我们从1972年开展了林业育苗化学除草试验。几年来,通过小面积的田间试验和生产上应用,筛选出十多种化学除草剂,初步总结出以除草醚、杀草醚、杀草安、灭草灵、杀草丹、百草稀、捕草净、五氯酚钠、阿特拉津、2.4—D丁酯等以及各种混合剂型的化学除草剂组成的林业育苗化学除草体系,摸索出一些规律,取得了良好的效果。
Forestry nursery application of chemical weeding is to achieve forestry nursery operations mechanization, serialization, reduce labor intensity, reduce nursery costs, improve seedling quality and effective technical measures. We carried out the forestry nursery chemical weeding test in 1972. Over the past few years, through a small area of field trials and production applications, screening more than 10 kinds of chemical herbicides, initially summed up to the weeding ether, grass grass ether, Grass net, sodium pentachlorophenate, atrazine, 2.4-D butyl ester, and various mixed-type chemical herbicide chemical nuisance-free herbicidal system, to explore some laws and achieved good results.
