Fish-vegetable symbiotic integration system

Abstract

The invention discloses a fish-vegetable symbiotic integration system comprising an aquaculture system, a planting system and an automatic integration control system. The aquaculture system comprises an aquaculture water trough, a water quality transformation trough and a physical and biological filter trough which is used for filtering feces of fish and shrimps. The planting system comprises a planting layer frame, a liquid recycling and filtering trough, a liquid activating trough and a liquid mixing monitoring device. Thereby, aquaculture and vegetable production can be integrated through the ecological design, nutrients of organic matters in the feces in the aquaculture water trough and subjected to through physical and microbial decomposition are supplied to the vegetables, application amount of plant liquid can be saved, the purification function of the planting system is performed upon water used for aquaculture, baits required by the fish and shrimps are provided, application amount of the baits can be saved, and benefits of industry can be increased; algae can be taken as the nutrients for the plant liquid and the fish and shrimps, so that the application amount of the liquid and that of the baits of the fish and shrimps can be saved, water quality can be purified, ecological balance can be achieved, and water resources can be saved.

Description

technical field [0001] The invention relates to a technology in the field of aquaculture and vegetable planting systems, in particular to an integrated fish and vegetable symbiosis system. Background technique [0002] In traditional aquaculture, due to the accumulation of fish excrement, the ammonia nitrogen in the water body increases, and the toxicity gradually increases, which is not conducive to the survival of fish, and the excrement produced pollutes the environment, and is affected by the environment during the production process. The impact is large, it is not easy to control manually, and the waste of water resources is large. In response to this problem, a fish-vegetable symbiosis compound farming system has emerged. It combines aquaculture and hydroponics, two completely different farming technologies, through ingenious ecological design, to achieve scientific synergy and symbiosis, so as to achieve fish farming. The ecological symbiosis effect of changing water...

Problems solved by technology

[0003] At present, most of the fish and vegetable symbiosis farming systems adopt the open-loop mode, that is, the fish pond and the hydroponic pond are connected through water pipes, and the water discharged from the fish pond is used as one-time irrigation water to directly supply the hydroponic pond without returning backflow. Supplement new water to the fish pond, while the excess water in the hydroponic pond is discharged to the waste water pond. This mode cannot make full use of water resources and greatly increases its cost. way more troublesome
