鱼菜循环式生态种养技术试验

Experiment on circular ecological fish-vegetable farming

为探索适合石家庄市鱼菜循环种养新模式,在3个大棚内进行了试验,试验池面积684 m^(2),养殖水体828 m^(3),建有蔬菜种植水槽2400 m^(2)。通过微流水集约化养殖、蔬菜无土栽培、尾水处理系统(硝化仓)达到鱼类养殖和蔬菜共作、水体循环利用。养殖试验实现单位鱼产量41.2 kg/m^(3),蔬菜年单位产量29.8 kg/m^(2),整个生产过程实现养殖用水循环利用和零排放。实践证明,这是一种高效、生态农业综合生产模式。

in order to explore a new model of circular ecological fish-vegetable farming suitable for the local area in Shijiazhuang,a experiment was carried out in 3 greenhouses with water area of 684 m^(2).The water volume was 828 m^(3),and a vegetable cultivation tank was built with water area of 2400 m^(2).Fish culture and vegetable farming was integrqated and aquaculture water was recirculated through intensive culture in micro-flowing water,hydroponics of vegetable and tail water treatment system(nitrification bin).The average annual output of fish and vegetable was 41.2 kg/m^(3)and 29.8 kg/m^(2),respectively.In the whole process,aquaculture water was recirculating and there was zero liquid discharge.It was proved to be an efficient,eco-agricultural integrated production model.
