这种高效、立体、新型种养模式有6大优点。一是由于茭白田养鱼、养鸭后,迫使农民只能使用低毒农药,这样茭白就成为无公害蔬菜,品质也有的提高。二是这种立体种养技术明显提高了土地和水资源利用率。三是鱼、鸭觅食了田间杂草、无效分蘖和茭白基部害虫(长绿飞虱、螟虫等),从而减轻虫害和 This efficient, three-dimensional, new planting and breeding mode has six major advantages. First, due to 茭 Baitian fish, duck, forcing farmers to use only low toxicity pesticides, so 茭 white pollution-free vegetables to become, the quality is also improved. Second, this three-dimensional planting and breeding technology has obviously improved the utilization of land and water resources. Third, fish, ducks foraging field weeds, ineffective tillering and scabies white base insects (long green planthopper, stem borers, etc.), thereby reducing pest and
