         管理信息

    物理方法:机械砍筏机或收割机,能在短期内有效地去除大量的生物量,但应小心使用,因为植物碎片会助长传播。收割也必须每一年做好几次。鼓式翻耕此植物的根系结合水下吸除,已被用来控制侵袭。在田纳西州使用水位操作,把水抽干,已有效地用于控制族群。使用底部障碍物,包括特制材料,如玻璃纤维,聚丙烯,或聚氯乙烯(PVC),拴在湖底阻挡阳光防止植物生长。底部障碍物是最适合局部地区的生长控制。

    化学方法:除水草剂也可使用,但很少成功。

    生物方法:北方湖泊的杂草会自然减少,与北美象鼻虫有关,Euhrychiopsis lecontie会对西洋蓍草造成重大损害,但对本地物种没有什么影响。象鼻虫可能可以当作生物控制剂。 English

            摘要: This report is the second stage in the development of a Border Control Programme for aquatic plants that have the potential to become ecological weeds in New Zealand. Importers and traders in aquatic plants were surveyed to identify the plant species known or likely to be present in New Zealand. The Aquatic Plant Weed Risk Assessment Model was used to help assess the level of risk posed by these species. The report presents evidence of the various entry pathways and considers the impact that new invasive aquatic weed species may have on vulnerable native aquatic species and communities.
