摘要
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。
At present, the means of controlling common waterhyacinth by chemicals and getting it out of water was not sustainable, which could even cause the secondary pollution. However the biological control of common waterbyacinth was sustainable although its protecting effects were slow. The comprehensive approch by combining biological control with chemical control, which was adopted by foreign countries, could achieve a fast, effective, continuous and even low cost aim of the control.
