ActiveCN107950435BGrowth aidTake advantage ofClimate change adaptationPisciculture and aquariaWater qualityPaddy field
The invention discloses a method for combining raceway-style perch cultivation and paddy-field nested crayfish cultivation, which combines the racetrack-type perch cultivation and paddy-field cultivation of crayfish. After the residual bait and feces of the perch in the breeding runway are concentrated and sucked, they are discharged into the paddy field where the crayfish are nested through the pipeline, so that the crayfish can eat the residual bait, and the paddy field absorbs the feces and purifies the water quality. At the same time, the water rich in nitrogen, phosphorus and other nutrients discharged from the runway is pushed into the paddy field ditch and paddy field through the water wheel aerator, so that the aquatic plants and rice in the paddy field ditch can absorb nitrogen, phosphorus and other nutrients in the water body, and purify the water quality . This combination makes the paddy field water become "living water", which is conducive to the growth of crayfish, so that the "waste" in the breeding runway has a more valuable place to go, and the water body in the purification area outside the runway is also fully utilized to achieve zero discharge of breeding sewage. At the same time, the land has been fully utilized to maximize its output value. It can realize the annual output of 473Kg of rice, 229Kg of crayfish and 51838Kg of perch on 50 mu of land, with an average benefit of 8810 yuan per mu.
