Fish and plant symbiosis system

Abstract

The invention discloses a fish and plant symbiosis system. The system comprises a fish culture device, a nitrification device, a plant cultivation device, a constructed wetland, a clear water tank and a sewage tank; the fish culture device, the nitrification device, the plant cultivation device and the clear water tank are communicated in sequence through pipelines, the fish culture device and the nitrification unit and the sewage tank, the constructed wetland, the clear water tank and the fish culture device are sequentially connected into a water closed circulation loop. For water closed circulation in the whole system, energy consumption is low, a large amount of water exchange is not needed, a large amount of water resources are saved, and the yield of fish and plants is increased, and fish culture and plant cultivation can achieve symbiosis for recycling, self-sufficiency is achieved, and then the industrial ecology and low cost are achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting and breeding, in particular to a fish-plant symbiosis system. Background technique [0002] At present, pure aquaculture and plant planting technologies are relatively mature. In simple aquaculture, it is necessary to put in aquaculture bait frequently, and the bait is often put in too much, resulting in a large amount of accumulation in the aquaculture pond. At the same time, a large amount of ammonia nitrogen and fish feces produced in the aquaculture will cause the quality of the aquaculture water to decline and cause water pollution. It is necessary to replace the aquaculture water body, which causes a lot of waste of water resources and serious pollution of the environment; and in planting, a large amount of fertilizer needs to be put in to meet the needs of plant growth. Not only the fertilizer is expensive, but also the cost of planting is increased. More importantly, excessi...

In simple aquaculture, it is necessary to put in aquaculture bait frequently, and the bait is often put in too much, resulting in a large amount of accumulation in the aquaculture pond. At the same time, a large amount of ammonia nitrogen and fish feces produced in the aquaculture will cause the quality of the aquaculture water to decline and cause water pollution. It is necessary to replace the aquaculture water body, which causes a lot of waste of water resources and serious pollution of the environment; and in planting, a large amount of fertilizer needs to be put in to meet the needs of plant growth. Not only the fertilizer is expensive, but also the cost of planting is increased. More importantly, the excessive use of chemical fertilizers will seriously pollute the soil, groundwater, etc., which will cause irreparable consequences to the natural ecological environment.
