鱼-鸭-菜生态种养模式的方法与效益摘要:鱼、鸭、菜混养技术是一种效益较高的生态渔业模式。于2010年在浙江省丽水市莲都区城关镇水东村养鸭场进行了鱼、鸭、菜共育试验。结果表明,鱼池为鸭提供了清洁的活动场所,而鸭子排泄的粪便为养鱼提供了充足的肥源,水面的空心菜使水体清洁,提高溶氧,也使池塘美观;,试验塘和对照塘净产值分别为61480元和11130元,∶∶,鱼、鸭、,经济效益显著。关键词:鱼、鸭、菜共育;生态经济系统;经济效益中图分类号::A文章编号:0439-811422-4570-03 MethodsandBenefitofFish-duck-waterspinachEco-cultivatingandBreedingModel XIAOJian-zhong,L?�BYao-ping Abstract:Thefish-duck-waterspinachco--cultivationsystem,thefishpondprovidesacleanactivityplacefortheducks,meanwhiletheducksuppliesanadequatesourceofmanureforthefish;Andthewaterspinachnotonlymakethewatercleanandincreasesthedissolvedoxygeninpond,,fish-duck-waterspinachco-cultivationmodelandonlybreedingfish,weresetinaduckfarminShuiguanvillage,Chengguangtown,Liandudistrict,Lishuicounty,Zhejiangprovincein2010toanalyzethebenefitofco--∶∶-duck-waterspinachco-cultivationsystemwasremarkable.
