【摘要】 小麦田施用甲磺隆后90天、210天播种玉米、棉花、大豆、花生、谷子5种作物,结果表明,甲磺隆对玉米、大豆、花生均有一定程度的影响,对棉花、谷子基本无影响。以玉米冀单29为指示作物,测定玉米主根长抑制率与甲磺隆浓度的关系,结果表明:玉米主根长抑制率与甲磺隆浓度的对数呈二次曲线相关,相关曲线为y=a(lgx)~2+blgx+c(r>0.98,P<0.04)。甲磺隆对不同玉米品种影响程度不同。更多还原

【Abstract】 Maize,cotton,soybean,peanut,and millet were planted in summer after metsulfuron was applied in wheat field.The residue of the herbicide did great damage to maize,soybean and peanut.Cotton and millet were not so sensitive.Using Ji Dan No.29 as the indicating plant,regression model[y =a(lgx)~2+ blgx + c]was set up which showed the good relationship(r>0.98,p <0.04) between inhibiting ratios of maize radicle length and the consistency of metsulfuron.更多还原
