摘　　要：在桉树营林技术方法中,幼林抚育是一个极其重要的环节,与人工除草相比,除草剂除草不仅能达到良好的除草效果,还能实现成本有效控制,但是在众多除草剂中找到最安全、有效、经济的除草剂,对于桉树幼林的生长至关重要。为此,主要对比了2种不同浓度草甘膦对桉树林下杂草(灌)的防治效果,比较了桉树的形态变化、树木生长变化与杂草控制效果的差异,结果表明:应用41%草甘膦浓度除草剂除草效果最佳。In the technical methods of Eucalyptus forest management, young forest tending is an important link. Compared with manual weeding, herbicide weeding can not only achieve good weeding effect, but also achieve effective cost control. However, finding the most safe, effective and economic herbicide among many herbicides is crucial for the growth of young Eucalyptus forests. This paper mainly compares the control effects of two different concentrations of glyphosate on weeds(irrigation) under eucalyptus forests. Through comparing the morphological changes of Eucalyptus trees, tree growth changes and the differences in weed control effects, the results show that 41% glyphosate concentration herbicide is the best herbicide.
