摘要 在大兴安岭地区选择桔梗田施用五种常用的化学除草剂,并进行除草效果比较研究,发现选用的除草剂对桔梗田杂草均有防效。通过实验数据比较,精哇禾灵、拿捕净防治桔梗田禾本科杂草效果明显。乙氧氟草醚、虎威防治桔梗田阔叶杂草效果明显。氟乐灵对目标杂草均有防效。阔叶杂草与禾本科杂草均有的桔梗田,可用乙氧氟草醚-精哇禾灵或虎威-精哇禾灵混剂防治。 Five commonly used chemical herbicides were applied to Platycodon grandiflorum field in Daxing'an Mountains,and their weed control effects were compared.It was found that the selected herbicides were effective in controlling weeds in Platycodon grandiflorum field.By comparing the experimental data,Quizalofop-p-ethyl and Sethoxydim had obvious effects on controlling Gramineae weeds in Platycodon grandiflorum field.Oxyfluorfen and Fomesafen had obvious effects on controlling broad-leaved weeds in Platycodon grandiflorum field.Trifluralin was effective against target weeds.Platycodon grandiflorum,which has broad-leaved weeds and gramineous weeds,can be controlled by oxyfluorfen-Quizalofop-p-ethylor Fomesafen-Quizalofop-p-ethyl mixture.
