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。
Abstract
Objective] The aim was to discuss the varieties and using methods of foliar applied herbicides of alfalfa field in Zhaodong of Jiamu-si Region.[Method] Through plot test of foliar applied herbicide, we researched the effects of seven herbicides on the seedling and grass con-dition of alfalfa at branching stage in Zhaodong.[Result] The herbicide treatments of alfalfa in Zhaodong included 5%Pursuit aqua, 4%Jind-ou 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, and 10% 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.
