摘要: 【目的】 指导胡萝卜田除草剂高效安全使用,筛选苗前土壤封闭除草剂最佳使用药剂及施用方式。【方法】 在内蒙古乌素图镇胡萝卜田采用4种除草剂(450 g/L二甲戊乐灵CS、330 g/L二甲戊乐灵EC、480 g/L氟乐灵EC、960 g/L精异丙甲草胺EC)、2种助剂和不同施药方式,以清水喷施为对照,共13个处理,研究不同处理对胡萝卜田杂草的防除效果。【结果】 供试4种除草剂中960 g/L精异丙甲草胺EC禾本科杂草防效显著低于480 g/L氟乐灵EC和330 g/L二甲戊乐灵EC(P<0.05);480 g/L氟乐灵EC在不同施用剂量下以3 000 mL/hm2 480 g/L氟乐灵EC+300 mL/hm2 助剂1处理对杂草防除效果最佳,禾本科杂草防效为93.12%、阔叶杂草防效为87.88%;2 205 mL/hm2 450 g/L二甲戊乐灵CS+300 mL/hm2助剂1处理对杂草防除效果最佳,禾本科杂草防效为99.10%、阔叶杂草防效为92.51%。【结论】 胡萝卜田苗前除草剂以2 205 mL/hm2 450 g/L二甲戊乐灵CS+300 mL/hm2助剂1防除效果最佳。

Abstract: 【Objective】To guide the efficient and safe use of herbicide in carrot field,and to screen the best use and application of herbicide in soil sealing before seedling.【Methods】To study the effect of different treatments on the control of weeds in carrot field,4 herbicides was used(450 g/L pendimethalin CS,330 g/L pendimethalin EC,480 g/L trifluralin EC,960 g/L refined metolachlor EC),2 adjuvants and different application methods,with clean water spraying as a control,a total of 13 treatments in carrot field of Wusutu Town of Inner Mongolia.【Results】Among the 4 herbicides tested,the control effect of 960 g/L refined metolachlor EC on grassy weeds was significantly lower than that of 480 g/L trifluralin EC and 330 g/L pendimethalin EC(P<0.05);3 000 mL/hm2 480 g/L trifluralin EC+300 mL/hm2 adjuvant 1 had the best weed control effect compared different application doses. The control effect of grassy weeds was 93.12%,and the control effect of broad-leaved weeds was 87.88%;2 205 mL/hm2 450 g/L pendimethalin CS+300 mL/hm2 adjuvant 1 treatment had the best weed control effect,and the control effect of grassy weeds and broad-leaved weeds was 99.10% and 92.51%,respectively.【Conclusion】Pre-seedling herbicide in carrot field was 2 205 mL/hm2 450 g/L pendimethalin CS+300 mL/hm2 adjuvant 1.
