这种立体种养模式有6大优点。(a)由于茭白田养鱼、养鸭后,农民只能使用低毒农药,这样茭白就成为无公害蔬菜,品质也有所提高。(b)这种立体种养技术明显提高了土地和水资源利用率。(c)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),从而减轻虫害和草害,减少使用农药次数和用量。(d)鸭 This three-dimensional planting and breeding mode has six advantages. (a) As a result of 茭 Baitian fish farming, after duck raising, farmers can only use low-toxic pesticides, so 茭 white became pollution-free vegetables, quality has also improved. (b) This three-dimensional planting technique has significantly increased land and water use efficiency. (c) The fish and ducks forage for field weeds, ineffective tillers and pest-based pests (eg, planthoppers, stem borers, etc.), thereby reducing pest and grass damage and reducing the frequency and amount of pesticides used. (d) Ducks
