Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.

[0026] The invention organically combines the production technologies of high-density aquaculture and soilless cultivation to form a fish-vegetable symbiosis system. The fish provides the nutrients needed for the growth of the vegetables, and the vegetables absorb the nutrients while purifying the water quality for the fish, and the two circulate in cycle. Aquaponics system of the present invention such as figure 1 As shown, it includes a relatively independent cultivation unit 10 and a planting unit 20 , wherein the cultivation unit 10 and the cult...

Abstract

The invention provides a fish and vegetable symbiotic system. According to the fish and vegetable symbiotic system, a breeding unit and a planting unit are arranged relatively independently so that different requirements of breeding and planting can be met. Breeding wastewater as organic liquid fertilizer is rich in all elements necessary for plant growing, also contains humic acid, amino acid and other nutrients, can improve the flavor of vegetables and has richer nutrients than hydroponic products. Thus, water obtained by removing suspended substances from waste water discharged from a breeding pool through a physical filter can be subjected to nutritional requirement adjustment through a nutrient conversion device to enable the pH value to drop to a range suitable for vegetable planting, and then the nutritional requirement adjusted water is delivered to the planting unit as organic liquid fertilizer. Water of the planting unit is absorbed and purified through plants and then the purified water can return to the breeding pool as water for breeding fish. Water evaporated by a system and water lost by plant transpiration is supplemented with fresh water supplemented by a water source supplementary device. Accordingly, the fish and vegetable symbiotic system provided by the invention can really achieve the zero emission standards.

Description

technical field [0001] The invention relates to the technical field of aquaculture and planting, in particular to a fish and vegetable symbiosis system. Background technique [0002] China is a large agricultural country, but its production methods are relatively backward. Traditional aquaculture has a low density, which leads to low feed utilization. Due to extensive management, the external environment is complicated, a large amount of sewage discharges, pollutes the environment, and is easy to contact with pathogens. In addition, the water quality environment Poor, there is the problem of abuse of antibiotics and fish medicines, which makes the farmed products have problems of zoonotic parasites. However, the traditional planting industry, especially vegetable planting, requires a large amount of land, and due to the abuse of pesticides and chemical fertilizers, it is easy to cause land compaction and environmental pollution. [0003] The fish and vegetable symbiosis is ...
