摘　　要：[目的]探讨佳木斯地区肇东苜蓿无药害除草剂品种和使用方法。[方法]通过茎叶处理除草剂小区试验研究7种除草剂对肇东苜蓿分枝期苗情和草情的影响。[结果]对肇东苜蓿无药害的药剂处理有5%普施特水剂、4%金豆水剂和10%利收乳油苗后2-4叶期喷雾。施用除草剂处理干草产量正常的有5%普施特水剂苗后2-4叶期喷雾、4%金豆水剂苗后2-4叶期喷雾、75%阔叶散悬浮剂苗后2-4叶期喷雾和10%利收乳油苗后2-4叶期喷雾,对干草产量影响大的是44%克莠灵水剂苗后2-4叶期喷雾和25%虎威水剂苗后2-4叶期喷雾。[结论]肇东苜蓿无药害除草剂品种和使用方法推荐5%普施特水剂苗后2-4叶期喷雾。[Objective]The aim was to discuss the varieties and using methods of foliar applied herbicides of alfalfa field in Zhaodong of Jiamusi Region. [Method] Through plot test of foliar applied herbicide,we researched the effects of seven herbicides on the seedling and grass condition of alfalfa at branching stage in Zhaodong. [Result]The herbicide treatments of alfalfa in Zhaodong included 5% Pursuit aqua,4% Jindou aqua and 10% Lishou EC. They were sprayed at 2-4 leaf stage after seedling. Treatments with normal dry grass yield were 5% Pursuit sprayed at 2-4 leaf stage,4% Jindou sprayed at 2-4 leaf stage,75% broadleaf powder suspending agent sprayed at 2-4 leaf stage,and10% Lishou EC sprayed at 2-4 leaf stage. Treatments had great impacts on dry grass yield were 44% Keyouling sprayed at 2-4 leaf stage,and 25% Huwil sprayed at 2-4 leaf stage. [Conclusion]5% Pursuit is recommended to be sprayed at 2-4 leaf stage for alfalfa in Zhaodong of Jiamusi Region.
