摘　　要：为了对马铃薯田中的多种杂草进行有效的防除,以大田马铃薯为研究对象,同薯23号为材料。除草剂侨神设5个浓度梯度,于马铃薯播后施药。试验结果表明,侨神作为土壤处理剂防除马铃薯田杂草,在用药量0.25-0.37 mL·m^-2范围内,可有效地防除反枝苋、马齿苋、无芒稗、藜等杂草。施药后30 d调查,总株防效为86.47%-95.45%;总鲜重防效为92.19%-98.54%。侨神在马铃薯田防除杂草用药量以0.25-0.37 mL·m^-2效果最好。In order to control various kinds of weeds in potato field effectively, field potato was used as the research object and Tongshu 23 as the material. Different concentrations of herbicide （Acetochlor, Metribuzin） was used on the potato after sowing. The results showed that the herbicide （Aeetochlor, Metribuzin） within the scope of 0.25 mL ·m^-2 -0. 37 mL·m^-2 could prevent and get rid of the annual weeds like Amaranthus retroflexus, Portulaca oleracea, Echinochloa crusgalli, Chenopdium album effectively. In 30 days after using herbicide, the preventing effect was 86.47%-95.45% for each plant. Fresh and heavy effect was 92. 19%-98. 54%. It could be better to use herbicide within 0.25 mL ·m^-2-0. 37 mL ·m^-2.
