摘要
试验探讨了在杉木、马尾松、柳杉和火炬松育苗过程中化学除草技术的应用,分析了果尔、氟乐灵、除草醚和扑草净的除草效果,结果表明:(1)果尔、氟乐灵和除草醚除草效果较好;(2)育苗中,在芽前和苗期两次应用果尔、氟乐灵或除草醚处理,即可基本不需要安排人工除草;(3)化学除草可节省除草用工的80%—90%,降低除草成本的80%—86%;(4)除草剂基本不影响苗木生长。
The experiment makes an approach to the application of chemicalweeding techniques in the course of raising seedlings of Cunninghamia lanceola-ta, Pinus massoniana, Cryptomeria fortunei, and Pinus taeda and the weedingeffects of Goal, Trifluralin, Nitrofen, and Prometryne are also analyzed in theexperiment. The results indicate that (1) the weeding effects of Goal, Triflu-ralin, and Nitrofen are better; (2) there is no need to arrange artificial weedingon the whole if Goal, Trifluralin, and Nitrofen are applied twice before the ger-mination and in the seedling stage;(3) the chemical weeding can reduce 80--90percentages of weeding time and 80--85 percentages of weeding cost; and (4)theherbicide does not affect the seedling growth basically.
