| 为了抑制薇甘菊 Mikania micrantha 的生长蔓延, 该研究连续 2 年 (2021—2022 年) 采用人工
清除与化学防治相结合的方式, 在中山市三乡镇实施薇甘菊防治。 化学防治使用 24%滴酸·二氯吡或
24%氨氯吡啶酸药剂, 每年在花期前对薇甘菊进行喷药, 连续治理 3 个月, 期间至少喷药 3 次, 不适合喷
药的地点则使用人工清除。 防治工作结束后, 调查其残存率和复发度。 结果表明, 在 74. 35 hm

| Abstract: |
| To inhibit the growth and spread of Mikania micrantha, this study was conducted for two consecutive years (2021—2022 ) to implement the control of M. micrantha in Sanxiang town of Zhongshan city by
combining artificial clearance and chemical control. 24% drop acid clopyralid or 24% picloram was selected as a
chemical control agent to spray M. micrantha before the flowering period of each year and was continuously treated for three months. At least three times agent spraying was carried out during the period, meanwhile, manual
removal was used in areas unsuitable for spraying. After the prevention and treatment, the residual rate and recurrence rate were investigated. The results showed that the residual rate of M. micrantha was controlled below
0. 3% and the recurrence rate was controlled below 0. 2% and below in the control area of 74. 3 hm

of the prevention task. The control M. micrantha had achieved remarkable results, and the effect of 24%
picloram on M. micrantha was equivalent to that of 24% drop acid clopyralid. |
