林业除草是营林生产过程的重要环节,美国孟山都公司研发的林用除草剂草甘膦以其杀草广谱、内吸传导性强的优势在林业生产中被广泛采用。然而随着草甘膦的过量使用,残留在林地土壤中的草甘膦势必增加,不仅作用于靶生物以防除杂草,而且对非靶生物也产生影响,导致林地生态系统结构改变,功能遭受破坏。近年来,虽然国内外学者对草甘膦在农业应用的环境行为和生态风险进行了大量研究,但对于草甘膦在林业上的研究鲜见报道。文中从草甘膦的除草机理、在林地土壤中的环境行为、林用生态风险以及合理使用等方面综述了草甘膦在林业应用中的研究进展,以期为人工林经营过程中草甘膦的合理使用提供科学参考。 Forestry weeding is an important part of the forest production process. The forest herbicide glyphosate developed by the Monsanto Company in the United States is widely used in forestry production for its advantages of broad-spectrum herbicide and strong internal absorption and conductivity. However, with the excessive use of glyphosate, the amount of glyphosate left in the forest soil will inevitably increase, not only acting on the target organisms to control weeds but also affecting non-target organisms, resulting in the structural changes and function of woodland ecosystems damage. In recent years, although domestic and foreign scholars have done a lot of research on the environmental behavior and ecological risk of glyphosate in agriculture, little research has been reported on the glyphosate in forestry. In this paper, we reviewed the research progress of glyphosate in the field of forestry from the weeding mechanism of glyphosate, the environmental behavior in forest soil, the ecological risk of forest and rational use of glyphosate in the forestry.
