摘要
200g/L百草枯水剂200mL/667m2、41%草甘膦异丙胺盐水剂200mL/667m2,分别兑水30L、40L、50L、60L,使用带扇形单喷头的背负式手摇喷雾器喷雾施药。结果表明百草枯以兑水40、50L的效果最好,药后7d的株数防效分别为96.87%和95.68%,药后15d的鲜重防效分别为96.83%和95.41%;草甘膦异丙胺盐以兑水30、40L的效果最好,药后15d的株数防效分别为96.80%和96.08%,药后30d的鲜重防效分别为96.75%和95.98%。
Paraquat（200g/L,AS）,and glyphosate（41% AS） were diluted with 30 L,40 L,50 L,60 L water respectively and sprayed at the rate of 200ml/667m2 using a hand-pumping sprayer with a single fan-shaped nozzle.The results showed that the control effects of paraquat at dosage of 200mL/667m2 diluted with 40 L or 50 L water were most effective,reaching 96.87% and 95.68% respectively 7 days after treatment.However,in terms of fresh weight control effects were 96.83% and 95.41% respectively on 15th day.The control effects of glyphosate diluted with 30 L or 40 L water were the best,which reached 96.80% and 96.08% respectively 15 days after treatment,and 96.75% and 95.98% in fresh weight control effects on 30th day.
