本文以探讨紫茎泽兰种群动态的规律,为生产上提供防除依据为目的,在不同的生境下进行了实地调查,并辅以人为模拟条件的田间实验作补充。结果表明,紫茎泽兰侵入力极强,生命力旺盛,在短期内群体一直处于上升状态,群落自然演替缓慢,实为当地为害严重的一种恶性杂草。欲控制其为害,必须采用综合防治措施,如:生态防除、化学防除、生物防除和机械防除,防治紫茎泽兰以在其侵入后的1—3年内进行效果最佳。
In order to explore the rule of the population dynamics of Eupatorium adenophorum and to provide a basis for the prevention and control of production, field investigation was conducted in different habitats and complemented by field experiments with man-made simulation conditions. The results showed that Eupatorium adenophorum invaders extremely strong and has strong vitality. In a short time, the population has been in an ascending condition, and the natural succession of the community is slow. It is actually a serious weed weeds. To control their damage, we must adopt comprehensive prevention and control measures, such as: ecological control, chemical control, biological control and mechanical control, prevention and treatment of Eupatorium so as to achieve the best effect within 1-3 years after its invasion.
