When single herbicide was used in the field for two years, the dominant species took place corresponding alternation. The community structure that originally mostly consisted of dicotyledonous weeds , such as Alopecurus aequalis sobol., etc.
通过连续几年的单一除草剂使用，烟田杂草的优势种群发生了相应变化，原来以看麦娘、马唐、稗草等单子叶杂草为主的群落结构演变成了现在以稗草、马唐及胜红蓟、两栖蓼、茴茴蒜为主的单、双子叶杂草混生结构，说明烟田施用除草剂会引起杂草群落结构变化，因此，在生产上则应注意除草剂的轮换使用。
