摘    要:通过室内理化指标测定及温室盆栽和大田试验,研究了有机硅助剂对莠去津的增效作用,并探讨了有机硅助剂对莠去津增效作用的机制.结果表明,有机硅助剂混用于莠去津后对阔叶杂草均有明显的增效作用,且用量最低,仅为喷液量的0.1%,有机硅助剂2#增效作用最明显,莠去津900 g a.i.·hm-2加入有机硅助剂2#后可增加防效40%...

关 键 词:有机硅助剂  莠去津  增效作用  增效机制

Abstract:Pot experiments and field experiments were conducted with organosilicone surfactants to determine weed control effect of atrazine and synergism mechanism.The results showed that atrazine applied with organosilicone surfactants provided a dramatic increase in weed control effect and dosage of organosilicone surfactants was only 0.1% of spray volume,especially OSS 2#.Atrazine at 900 g a.i.·hm-2 applied with OSS 2# enhanced broad weed control effect by 40%,exceeded weed control effect of atrazine at 1 200 g a.i.·hm-2 and was similar to the control effect of atrazine at 1 800 g a.i.·hm-2.It indicated that synergism mechanism of organosilicone surfactants on herbiciedes was decreasing the surface tension and increasing spreading diameteris and retention.
Keywords:organosilicone adjuvant  atrazine  synergism  synergism mechanism
