摘　　要：针对胡麻田间杂草藜,选用48%灭草松AS 3000、3375、3750、4125、4500 mL/hm^(2) 5个浓度进行防除,在药液中添加助剂GY-Tmax,研究助剂对灭草松防除藜的增效作用,并对胡麻生长的安全性进行综合评价。结果表明,添加助剂喷施48%灭草松AS不同剂量处理,药后45 d株防效提高7.5~37.5个百分点,鲜重防效提高2.9~32.3个百分点,增效极显著。喷施48%灭草松4500 mL/hm^(2)株防效和鲜重防效最高,分别为85.0%和94.6%。添加助剂GY-Tmax喷施3375 mL/hm^(2)株防效和鲜重防效分别达到87.0%和95.8%,灭草松用量减少1125 mL/hm^(2),减量达25%,减量极显著。喷施48%灭草松AS不同剂量及添加助剂GY-Tmax对胡麻生长没有抑制。Bentazone 48% AS 3000 mL/hm^(2), 3375 mL/hm^(2), 3750 mL/hm^(2), 4125 mL/hm^(2) and 4500 mL/hm^(2) with the addition of additive GY-Tmax were used control the chenopodium album on oil flax, and its efficacy and safety on oil flax were evaluated comprehensively. The results showed that spraying bentazone 48% AS with different dosage increased the control effect by 7.5%-37.5% and the fresh weight control effect by 2.9%-32.3% after 45 days. The control effects of spraying bentazone 48% at 4500 mL/hm^(2) were 85% and 94.6%, respectively. The control effect of 3375 mL/hm^(2) of GY-Tmax was 87% and 95.8%, respectively. The dosage of bentazone decreased by 1125 mL/hm^(2) and 25%, which was very significant. The effect of spraying bentazone 48% AS with different dosage and adding additive GY-Tmax did not inhibit the growth of oil flax.
