在温室栽培条件下,采用Gowing法评价磺草酮与莠去津混用的联合作用类型。结果表明,二者混用后对稗草和反枝苋的作用效果均明显提高;混合剂对稗草表现出明显的增效作用,在磺草酮400g/hm2,莠去津800、900g/hm2时对稗草和反枝苋的增效作用最为明显,其鲜重抑制率(E-E0)分别为9.1%和9.5%;混合剂对反枝苋作用效果表现为相加作用。
Under greenhouse cultivation conditions, Gowing method was used to evaluate the combined action of sulcotrione and atrazine. The results showed that the combination of the two had significant effect on barnyardgrass and Amaranthus retroflexus; the mixture showed obvious synergistic effect on barnyardgrass, 400g / hm2 of sulcotrione, 800, 900g / hm2 of atrazine (E-E0) were 9.1% and 9.5%, respectively. The effect of the mixture on the effect of Amaranthus retroflexus was additive.
