摘  要：
采用田间试验的方法,测定了几种除草剂单剂和混用配方对胡麻田恶性杂草野艾蒿的防除效果及对胡麻生长发育的影响。结果显示,75%二氯吡啶酸SG+56%2甲4氯钠盐SP、75%二氯吡啶酸SG+90%莠去津WG混配、75%二氯吡啶酸SG单剂对野艾蒿的株防效、地上部鲜重防效、地下部鲜重防效分别达到93.24%～97.46%、94.69%～96.77%和90.13%～96.40%,对靶标杂草野艾蒿防除效果明显且对胡麻无药害,胡麻产量较空白对照分别增加36.59%、4.14%和20.86%。48%灭草松AS虽对野艾蒿的综合防效较低,但其对胡麻无药害且胡麻蒴果数、千粒重较大,胡麻产量较空白对照增长61.27%。90%2甲·草甘膦SP、82%草甘膦异丙胺盐AS、20%氯氟吡氧乙酸EC、70.5%2甲·唑草酮WG、20%敌草快AS 5种除草剂对胡麻安全性低,不宜应用于胡麻田野艾蒿的防治。结合各除草剂处理后胡麻的药害、经济性状、生物产量、籽粒产量以及对野艾蒿的防除效果进行综合分析,胡麻田野艾蒿防除除草剂选择适宜度依次为:75%二氯吡啶酸SG+56%2甲4氯钠盐SP混配>75%二氯吡啶酸SG>48%灭草松AS>75%二氯吡啶酸SG+90%莠去津WG混配。本文为胡麻田恶性杂草野艾蒿的化学防除提供了理论依据。

摘  要：
Field experiment method was conducted to study the control effect of several herbicides and mixtures on Artemisia lavandulaefolia and influence on the growth of flax. The results showed that the plant control effect, fresh weight control effect of ground or underground part of clopyralid 75% SG+ MCPA-Na 56% SP, clopyralid 75% SG+ atrazine 90% WG, clopyralid 75% SG reached more than 96%, 93% and 90%, respectively. They all have an obvious control effect on A. lavandulaefolia and no damage to flax, the yield of flax increased by 36.59%, 4.14% and 20.86% than blank control. Although comprehensive control effect of bentazone 48% AS on A. lavandulaefolia is low, but it's no harm to flax and the number of capsularfruit and 1 000-seeds weight of flax is larger, the yield of flax increased by 61.27% than blank control. MCPA·glyphosate 90% SP, glyphosate isopropylammonium 82% AS,fluroxypyr 20% EC, MCPA·carfentrazone-ethyl 70.5% WG and diguat 20% AS can't be adopted to prevent A. lavandulaefolia in flax field due to the low safety on flax. Combined with the phytotoxicity, economic characters, biological yield, grain yield of flax and the control effect of A. lavandulaefolia were analyzed, the selection suitability of herbicides to control A. lavandulaefolia in flax field as follows: clopyralid 75% SG+MCPA-Na 56% SP>clopyralid 75% SG>bentazone 48% AS>clopyralid 75% SG+atrazine 90% WG. This paper provide a theoretical basis for chemical control of A. lavandulaefolia in flax field.
