摘要: 为了验证20%氟草烟乳油(EC)(使它隆)防除小麦田杂草的效果,采用含有不同含量有效成分的氟草烟对小麦田杂草的防除效果进行了试验。结果表明, 施药后30、40 d,防除杂草的综合株防效分别为88.50%~95.01%、78.72%~85.13%;综合鲜重防效为85.57%~94.35%。20%氟草烟EC可减少麦田杂草对土壤氮、磷、钾的吸收,保持土壤肥力。

Abstract: In order to verify the effects of 20% fluroxypyr EC on controlling weeds in wheat fields, 20% fluroxypyr EC for controlling weeds in wheat fields was tested. The results showed that the comprehensive plant control effect of weed control was 88.50%~95.01%、78.72%~85.13% 30 days and 40 days after application, respectively; The comprehensive fresh weight control effect was 85.57%~94.35%.20% fluroxypyr EC can reduce the uptake of nitrogen, phosphorus and potassium by field weeds and maintain soil fertility.

Key words: fluroxypyr, broad-leaved weeds in wheat field, control effects
