| 中文摘要:为了明确除草剂42.5%二甲四氯·氯氟吡氧乙酸EC和50％双氟磺草胺SC不同配比对小麦返青期杂草的防治效果，采用随机区组法开展田间小区药效试验。结果表明， 42.5%二甲四氯·氯氟吡氧乙酸EC 750 mL·hm-2+50％双氟磺草胺SC 180 mL·hm-2、42.5%二甲四氯·氯氟吡氧乙酸EC 1 050 mL·hm-2+50％双氟磺草胺SC 180 mL·hm-2和55%苯·唑·二甲钠750 g·hm-2对4种杂草均有较高的防效，但42.5%二甲四氯·氯氟吡氧乙酸EC 750 mL·hm-2+50％双氟磺草胺SC 180 mL·hm-2较55%苯·唑·二甲钠750 g·hm-2对小麦安全，较42.5%二甲四氯·氯氟吡氧乙酸EC 1 050 mL·hm-2+50％双氟磺草胺SC 180 mL·hm-2经济。因此， 42.5%二甲四氯·氯氟吡氧乙酸EC 750 mL·hm-2+50％双氟磺草胺SC 180 mL·hm-2可以作为试验区防治麦家公、荠菜、播娘蒿的首选药剂。 |

| Abstract:In order to define the control effects the mixture herbicide of 42.5% EC Mixed with MCPA and Fluroxypyr conbined with 50％ florasulam SC on broad leaf weed in wheat field, field trial were investigated by adopting the randomized block design. The result showed that the control effect of 750 mL·hm-2 42.5% EC Mixed with MCPA and Fluroxypyr conbined with 50％ Florasulam SC 180 mL·hm-2, 1 050 mL·hm-2 2.5% EC Mixed with MCPA and Fluroxypyr conbined with 50％ Florasulam SC 180 mL·hm-2,and Kuoji were better in controlling four weeds, but 750 mL·hm-2 42.5% EC Mixed with MCPA and Fluroxypyr conbined with 180 mL·hm-2 50％ Florasulam SC were safe to wheat than Kuoji, and cost-effective than 1 050 mL·hm-2 42.5% EC Mixed with MCPA and Fluroxypyr conbined with 50％ Florasulam SC 180 mL·hm-2. In consequence, 750 mL·hm-2 42.5% EC Mixed with MCPA and Fluroxypyr conbined with 50％ Florasulam SC 180 mL·hm-2 could be used as the first choice to control Lithospermum arvense, Capsella bursa-pastoris, Descurainia sophia in local. |
