摘　　要：通过水培法研究了4种不同烟嘧磺隆·莠去津的剂型(20%烟嘧磺隆.莠去津可分散油悬浮剂、22%烟嘧磺隆.莠去津油悬浮剂、23%烟嘧磺隆.莠去津悬浮剂、79%烟嘧磺隆.莠去津水分散粒剂)对后茬作物幼苗生长的影响。结果表明,烟嘧磺隆.莠去津的不同剂型对于油菜和萝卜主根伸长的影响较大,在浓度仅为10mg/L时,对后茬作物就具有抑制作用;而对油菜和萝卜的芽长则影响较小,当药剂浓度大于80 mg/L才对后茬作物有影响;而对于小麦,可分散油悬浮剂对小麦的主根伸长和芽长的影响较大,而其他3个剂型的影响相对较小。The effects of four different formulation of nicosulfuron · atrazine （ nicosulfuron · atrazine 20% OD, nicosulfu- ron · atrazine 22% OF, nicosulfuron · atrazine 23% SE and nicosulfuron · atrazine 79% WG） on the post - crop seed- lings growth were studied by water culturing method. The result showed that different formulation of nicosulfuron· atrazine presented great effect on taproot elongation of radish and rape,even at the dosage of 10 mg/L, the root growth of post - crop could be inhibited obviously,but a little effect can be shown on the shoot growth of radish and rape, only when the concentration of nicosulfuron · atrazine got over 80 mg/L, inhibitent effect might be shown on the shoot growth of radish and rape post - crop. Nevertheless, nicosulfuron · atrazine 22% OF presented great effects on the taproot elongation and shoot growth of wheat post - crop, but a little effect can be shown from the other three formulations.
