| 摘 要： | 盆栽试验条件下，比较了乙草胺、草净津和莠去津及其三者组成的混剂用作土壤处理与茎叶处理剂对玉米安全性，杀草谱及除草效果。结果表明，药剂各处理对玉米安全。土壤处理，3种单剂对单子叶杂草株防效差别不大，对双子叶杂草株防效依次为：乙草胺＝秀去津＞草净津，杂草鲜重抑制效果相当，ED50、ED90相近，分别为154．4－160．4g.ai/hm^2和715．1－871．1g.ai/hm^2；茎叶处理，对单子叶杂草株防效依次为：乙草胺＝莠去津＞草净津，对双子叶杂草株防效依次为：草净津＞莠去津＞乙草胺，杂草鲜重毒力依次为莠去津＞乙草胺＞草净津，ED50、ED90分别为78－107．9g.ai/hm^2和412．3－1271．4g.ai/hm^2。3种混剂杀草谱较单剂广、效果高。

| Abstract: | The safety and scope of weed control and activity of herbicides was determined through test of basin cultivation.The results showed that they were safe to maize.When herbicides used by soil treatment,the plant effect to grassy weeds had no remarkable difference,the order of plant effect to broadleaf weeds is:acetochlor=atrazine>cyanazine.The weight effect had no remarkable difference.When by seedling treatment,the order of plant effect to grassy weeds is:acetochlor=atrazine>cyanazine,the order of plant effect to broadleaf weeds is :cyanazine>atrazine>acetochlor.The order of weight effect is:atrazine>acetochlor>cyanazine.The 3 kinds of its mixture give wider scope of weed control and higher activity. |
