介绍一个寒冷地区酸性沼泽地综合养鱼开发模式的生产技术措施及其经济、生态效益。“七五”期间,开发荒芜沼泽地建立稻、鱼、藕、菰综合养鱼模式98亩,采取池塘养鱼、池埂旱作、肥水灌稻、稻田养鱼、鱼藕共生、引种草(菰)、综合利用等措施,5年年均产值30591.40元,纯效益3708.20元,沼泽地亩创产值312.20元,纯利润37.80元.投入产出比1:1.14。模式的运行生产改善了沼泽土壤的理化性质,促进了营养物质的有效化,收到培肥土壤、增加空气湿度、维持生态平衡的效果。
This paper introduces the production technical measures and their economic and ecological benefits of a comprehensive fish farming development model in acidic wetlands in cold regions. During the “Seventh Five-year Plan” period, a total of 98 mu of rice, fish, lotus root and 菰 comprehensive fish farming patterns will be set up in barren marshy areas. Pond fish farming, pond water harvesting, paddy field irrigation,菰), comprehensive utilization and other measures, the 5-year average annual output value of 30591.40 yuan, net profit of 3708.20 yuan, marsh acres of output value of 312.20 yuan, net profit of 37.80 yuan. Input-output ratio of 1: 1.14. The mode of operation and production improves the physical and chemical properties of swamp soil, promotes the effectiveization of nutrients, receives the effect of fertilizing soil, increasing air humidity and maintaining ecological balance.
