摘　　要：为充分利用生物间互利共生关系、减少水稻病害和杂草,发挥稻田湿地养殖效能,形成全天候、多层次、多级利用的互济共生的生态体系,于2020年8月—2021年12月在上海市崇明区开展了综合“稻虾轮作”与“稻鱼种养结合”的“一稻多渔”(水稻-瓯江彩鲤-克氏原螯虾)综合种养新模式试验。结果表明:“一稻多渔”模式的稻田平均产值为150 112.5元/hm^(2),与传统的“稻虾轮作”或“稻鱼种养结合”相比较,分别提高了26.84%和159.60%。试验说明,“一稻多渔”模式能够显著提高养殖效益。In order to solve the problem that the rice-shrimp(Procambarus clarkii)rotation mode fails,and make full use of the mutually beneficial symbiosis between organisms,effectively reduce the rice diseases and weeds,give full play to the efficiency of rice field wetland cultivation,and form an all-weather,multi-level ecological system of mutual economic symbiosis,a new model of comprehensive cultivation of rice and multi-fish(rice-Oujiang color carp-Procambarus clarkii)which combined of the rice-shrimp rotation and rice-fish farming was tesed in Chongming District of Shanghai from Aguest 2020 to December 2021.The result showed that the average output value of the new model was 150112.5 RMB/hm^(2) which was 26.84%and 159.60%higher than the traditional rice-shrimp rotation and rice-fish farming model,respectively.The result proved that the new model of comprehensive cultivation of rice and multi-fish could significantly improve the economic benefit.
