摘　　要：为了筛选出对亚麻田间阔叶杂草具有高效、安全防除效果的除草剂组合,采用5种除草剂的7种组合对亚麻苗期杂草3~5期茎叶进行喷雾处理。结果表明,喷雾处理后,40%2甲·辛酰溴EC 750 mL/hm^2+30%二氯吡啶酸AS 900 mL/hm^2、40%2甲·辛酰溴EC 750 mL/hm^2+48%灭草松AS 2250 mL/hm^2两种组合在施药后45 d株防效、鲜重防效分别达到94.51%、94.80%和91.01%、90.81%。因此,这两种药剂组合用水量900 kg/hm^2,在亚麻苗高达到7~9 cm,杂草3~5叶期进行均匀喷雾处理,对亚麻田阔叶杂草具有良好的防除效果,可在生产上推广使用。The paper aims to screen out effective herbicides with high efficiency and safety control effect on broadleaf weeds in flax field.It is made up by using 7 mixed combinations of 5 herbicides for seeding with spraying treatment.40% MCPA-sodiam and bromoxynil octanoate EC 750 mL/hm^2＋ 30%clopyralid AS 900 mL/hm^2,after 45 days,the control effect and the fresh weight of the plant were 94.51% and 94.80% respectively.40% MCPA-sodiam and bromoxynil octanoate EC 750 mL/hm^2＋48% bentazone AS,after 45 days,the control effect and the fresh weight of the plant were 91.01% and 90.81% respectively.40% MCPA-sodiam and bromoxynil octanoate EC 750 mL/hm^2＋ 30% clopyralid AS 900 mL/hm^2 and 40% MCPA-sodiam and bromoxynil octanoate EC 750 mL/hm^2＋ 48% bentazone AS,at the height of 5-7 cm surface spray treatment,had good control effect on flax,which can be applied in large area for production.
