摘要 [目的]研究不同除草剂对亚麻中菟丝子的防除效果,以期为亚麻田防治菟丝子提供参考。[方法]以亚麻品种阿卡塔为试材,冬季在温室大棚中对茎叶生长期的亚麻植株喷施5种除草剂,观察其防治菟丝子的效果及亚麻生长情况。[结果]在亚麻苗高5cm以后喷施3000mL/hm2地乐胺防治菟丝子的效果较好且亚麻苗能正常生长;在亚麻快速生长期之前喷施草甘膦和敌草隆对菟丝子生长有抑制作用,之后则防治效果较差,但喷施草甘膦会使亚麻苗死亡;甲草胺、乙草胺和敌敌畏处理与对照相比,菟丝子数量少于对照,可能这些除草剂对菟丝子的生长有抑制作用。[结论]喷施地乐胺能相对有效地防治菟丝子。 [Objective] To study control effect of different herbicides against flax dodder,in order to provide reference for the control of dodder in flax.[Method]In winter,5 herbicides were sprayed to flax stem and leaf growth period in greenhouse,the efficacy of different treatments in controlling dodder weed and the growth of flax (Akata) was observed.[Result]The effect of butralin against flax dodder before 5 centimeter of flax seedling was better than others and the flax could grow normally.Moreover,the growth of dodder was inhibited by spraying glyphosate and diuron before the fast growth stage of flax,after that was poor,and it proved that the flax seedlings would be killed by spraying glyphosate.Also,the data revealed that some herbicides (methylamine,ethylamine and dichlorvos) could inhibit the growth of dodder weed because of the mount of dodder were less than CK.[Conclusion]The dodder in flax could be prevented by spraying butralin,relatively.
