摘　　要：选用多年生双子叶植物作为替代植物,不仅能够达到持续控制紫茎泽兰的目的,而且可以便利伴生单子叶杂草治理。但替代植物种类的选择及伴生阔叶杂草的治理仍需要加以解决。在贵州对4种替代植物的试验结果表明,葛藤生长迅速,对地表盖度好,替代控制紫茎泽兰效果可达96%以上,而其他替代植物种类的盖度较差。葛藤伴生的阔叶杂草可用除草剂氟磺胺草醚和乙羧氟草醚防除,在推荐剂量下对幼苗期的紫茎泽兰或假臭草的防效可达99%以上,且对葛藤安全;相反,除草剂甲氧咪草烟和异恶草酮效果较差。Replacement by a selected perennial dicotyledonous plant,not only can provide sustainable control of Ageratina adenophora ( syn.Eupatorium adenophorum ) but also can facilitate the management of associated monocotyledonous weeds.The choice of plant species and control measurement of associated broadleaf weeds still needs to be addressed.A-mong four possible replacement plants,Pueraria lobata grew rapidly with good ground coverage and achieved up to 96%replacement or control of A.adenophora,while the coverage of other replacement plants were poor in Guizhou Province. Fomesafen and fluoroglycofen effectively controlled associated broadleaf weeds in a P.lobata field.At their recommended dose,both herbicides controlled up to 99%A.adenophora and P.clematidea at their seedling stage with adequate selec-tivity to P.lobata.On the contrary,imazamox and clomazone were ineffective.
