入侵杂草薇甘菊的化学防除

The research on chemical prevention on the invaded weed——Mikania micrantha H.B.K

在广东内伶仃岛选择薇甘菊危害较严重的地段,采用内吸传导型除草剂森草净进行了化学防除试验。持续两年半的试验结果表明,0.01～0.1g·m^2(有效成分)的森草净对样地薇甘菊有极好的杀灭效果。试验还表明,森草净对岛上的大多数木本、藤本和草本植物都较安全,对样地的物种多样性无不良影响。因此,森草净是防治薇甘菊的首选除草剂。

Experiments of Chemical Salfometuron-ethyl to control M, micrantha in Neilingding island, where is seriously endangered by Mikania micrantha H.B.K, had been performed for two years and a half. The results showed that 0.01-0.1 g Salfometuron-ethyl · m-2 could kill M. micrantha effectively. The experiment also indicated that Salfometuron-ethyl was safe for most woody plants, herbaceous plants and vine plants and caused no harm to biological diversity in the tested field. Thus, Salfometuron-ethyl is suggested to be the most suitable herbicide to control M. micrantha.
