摘 要：
在室内控制的试验条件下 ,以马唐、反枝苋等为主要供试杂草测定了噻磺隆和乙草胺混用的增效作用 ,并进行了混剂对大豆的药害试验。结果表明 ,噻磺隆和乙草胺混用的增效 1倍 ;用单用噻磺隆所需药量的 2 2 %的计量与乙草胺混用就能达到与噻磺隆单用相当的防效 ,大幅度降低了噻磺隆的用量 ,从而减轻了其药效和对作物药害受土壤质地、pH值、有机质含量和降雨量等环境条件的影响 ;噻磺隆和乙草胺的混剂能防除大部分单、双子叶杂草 ,扩大了杀草谱 ;混剂对玉米和大豆的安全性好于噻磺隆和乙草胺单剂

摘 要：
The chemical efficiency of the mixture of Saihuangnong and Yicaoan on weeds, fingergrass and redroot amaranth, and also on soybean was conducted in controlling condition indoor. The result showed that the efficiency of mixture was increased one time than that of the single use of chemic respectively. The application of 22% of Saihuangnong mixtured with Yicaoan had same chemical efficiency as 100% of Saihuangnong application, which protected the environmental and soil conditions and lessened the chemical injury to crops. The mixture enlarged the range of weeds' control and also had well safety to soybean production.
