| 摘 要： | 在河北省曲周县选择6个村庄的麦田进行春草秋治效果试验,不同村庄的小麦主栽品种不完全相同。采用对比试验设计,2013年11月中旬（小麦播种后1个月）利用自走式机械喷药机用苯磺隆150～180 g/hm^2对水450 kg/hm^2喷雾施药,以不进行任何处理的麦田作为对照。2014年3月对麦田杂草的发生种类和数量进行了调查。结果表明：播娘蒿为该地区麦田的主要杂草;春草秋治可以有效降低示范方杂草的发生种类、田间频率和田间密度,降低播娘蒿的相对密度,个别地块甚至出现杂草灭绝的效果。春草秋治技术具有较好的应用效果和推广前景。 |

| Abstract: | The wheat fields of six villages in Quzhou County,Hebei Province were chosen to conduct a survey aiming at understand the effect of weed control before winter in winter wheat field.The main varieties of wheat in each village were not all the same.The contrast test was adopted that using self-propelled mechanical spraying machine with tribenuron methyl 150-180 g / hm^2 and water 450 kg / hm^2 to spray pesticide in the middle of November,2013（ one month after wheat seeding） and the fields that did not make any deal with as controls.Then the occurrence species and quantity of weeds in wheat field were investigated in March,2014.The results showed that Descurainia scphia was the main weed in the district and weed control before winter could greatly reduce the species,quantity and relative density of winter wheat field compared to the ordinary fields.The relative density of Descurainia scphia was also reduced.The weed control before winter has wide application and popularization prospect. |
