【摘要】 本文采用高梁根茎法,随机区组设计,研究多效唑(MET)对磺酰脲类除草剂药效的影响。结果表明:甲磺隆、氯磺隆及MET随着浓度的升高,高梁的根长、茎长逐渐降低,效果显著;甲磺隆、氯磺隆分别与MET混用,具有正交互作用,即MET对甲磺隆、氯磺隆药效的发挥具有促进作用。更多还原

【Abstract】 With the sorghum method,this experiment was conducted to study the influence of MET on control efficacy of sulfonylurea herbicides.Experimental units were arranged in a randomized block design.The results showed that the length of root and stem decreased gradualy with increasing the rates of the sulfonylutea herbicides.Mixing MET and methsulfuron- methyl promoted significandy the control efficacy of herbicides and so did mixing MET and cholrsulfuron.更多还原
