摘　　要：为了解不同除草剂对桉树林薇甘菊的除杀效果,本研究选择了硝磺·莠去津50%粉剂、乙羧氟草醚乳油、草甘膦铵盐粉剂、紫薇清水剂、草铵膦水剂、滴酸·草甘膦水剂、甲嘧磺隆粉剂等7种药剂进行了薇甘菊防治试验。结果表明:草甘膦铵盐防治效果优于其他药剂,以常规用药量、常规用药量+50%分别防治桉树幼林和成熟林薇甘菊,均可达到6个月内不复萌的效果;针对薇甘菊攀援危害的成熟桉树林,“喷药+割藤”防治措施明显优于单纯的喷药防治措施。In order to examine effectiveness of different herbicides for controlling Mikania micrantha in Eucalyptus plantations,seven herbicide preparations including:nitro-sulfonate&atrazine 50%powder;conpete 10%wp;ammonium glyphosate powder;24%dropping acid and dichloropyrazine water agent;glufosinate water agent;dropping acid and glyphosate water agent;and,Metsulfuron methyl powder;were tested in a field trial.Results showed the control effect of ammonium glyphosate was better than that of the other six herbicides.This herbicide could effectively kill M.micrantha with no re-sprouting within 6 months in juvenile and mature Eucalyptus plantations,when applied at either conventional dosage or 1.5 times the conventional dosage.For mature Eucalyptus plantations damaged by M.micrantha climbing up trees,′spraying and rattan cutting′control measures proved obviously better than simply spraying herbicide with no cutting or other physical interventions.
