摘  要：
[目的]明确5种除草剂以不同剂量施药对野艾蒿的防除效果及对胡麻的安全性。[方法]田间设置75%二氯吡啶酸可溶粒剂、90%莠去津水分散粒剂、56%2甲4氯钠盐可溶粉剂、48%灭草松水剂、30%苯唑草酮悬浮剂不同施药剂量的处理,评估除草效果及安全性。[结果]75%二氯吡啶酸可溶粒剂以150 g/hm~2施药对野艾蒿的株防效和鲜重防效均达到97%以上,90%莠去津水分散粒剂以1650 g/hm~2施药对野艾蒿的株防效和鲜重防效分别为77.28%、92.25%,56%2甲4氯钠盐可溶粉剂以450 g/hm~2施药对野艾蒿的鲜重防效为69.45%,48%灭草松水剂以4500 mL/hm~2施药对野艾蒿的鲜重防效为67.71%,30%苯唑草酮悬浮剂不适于野艾蒿的防除。[结论]筛选出的除草剂以最佳剂量施药对野艾蒿防除效果良好,对胡麻安全且增产效果明显。

摘  要：
[Aims] This study aims to determine the control effects of five herbicides at different doses against Artemisia lavandulaefolia and the safety of flax. [Methods] The different dose treatments were set in field trials including clopyralid 75% SG, atrazine 90% WG, MCPA-Na 56% SP, bentazone 48% AS, topramezone 30% SC. [Results] The plant control effect and fresh weight control effect of clopyralid 75% SG at 150 g/ha was over 97%. The plant control effect and fresh weight control effect of atrazine 90% WG was 77.28 and 92.25% respectively at an optimal dose of1650 g/ha. The fresh weight control effect of MCPA-Na 56% SP at 450 g/ha was 69.45%. The fresh weight control effect of bentazone 48% AS was 67.71% at dose of 4500 mL/ha. Topramezone 30% SC is not suitable for control of A.lavandulaefolia. [Conclusions] The selected herbicides at the best dose for controlling A. lavandulaefolia in flax field was safe and control effect was good, the yield increased also obviously.
