目前在水葫芦治理中 ,国内多采用人工打捞和化学药剂防治 ,防除效果均未能取得持效 ,且容易造成二次污染。生物防治水葫芦虽然速度较慢 ,但防治效果具有较强的持久性。国际上多采用综合治理的方法 ,即 :将生物和化学方法协调配合 ,可以达到快速、有效、持续而低廉的控制目的 Currently in the water hyacinth treatment, the domestic use of artificial salvage and chemical control, prevention and control are unable to achieve sustained effect, and easily lead to secondary pollution.
