How does the aquaponics system work? Why aquaponics is not successful

Aquatic vegetable system, this way is like China's rice-fish co-cropping system, the difference is that the breeding and planting separation symbiosis, that is, the cultivation field is covered with a waterproof cloth, backfilled with silt or soil, and then irrigated to build an aquatic vegetable planting bed, the water of the breeding pond is directly discharged into the farmland, and then returned from the other end to the collection and return to the breeding pond, so that the wastewater has no leakage under the laying of the tarpaulin, and the aquatic vegetables can fully filter the waste liquid, and also achieve a good biological filtration effect, which is a bit similar to the natural swamp wetland system. For example, the symbiosis of water white and fish, the symbiosis of aquatic vegetables such as callo-rich mushrooms, etc., can be designed by this system.

Aquaponics technology has a simple principle and strong practical operability, which can be suitable for large-scale agricultural production, and can also be used for small-scale family farms or urban hobby agriculture, and has a wide range of application prospects. In the specific practical operation, it should be noted that the dynamic adjustment of the proportion between fish and vegetables, ordinary vegetables and conventional breeding density, generally a cubic body of water can produce 50 catties of fish per year, and at the same time **10 square meters of melons, fruits and vegetables of fertilizer and water demand. The family-style aquaponics system generally only needs 2-3 cubic meters of water with 20-30 square meters of vegetable cultivation area, which can basically meet the consumption needs of 3-5 family vegetables and fish products, which is a farming model that is very suitable for urban or rural courtyard production, and is also the main technology and trend of urban agriculture development in the future.

Aquaponics is a new type of composite farming system, which combines aquaculture and vegetable production, two completely different farming technologies, through ingenious ecological design, to achieve scientific synergistic symbiosis, so as to achieve the ecological symbiosis effect of fish farming without water quality worries, and vegetable cultivation without fertilization. Achieving a harmonious ecological balance between animals, plants and microorganisms is a sustainable and circular zero-emission low-carbon production model in the future, and it is the most effective way to effectively solve the agricultural ecological crisis.

Aquaponics farming systems have the following models:

1. Closed cycle mode: the water discharged from the breeding pond is treated by the nitrification bed microorganisms, and enters the vegetable cultivation system in a circular way, and after the biological absorption and filtration of the vegetable roots, the treated wastewater is returned to the breeding pond, and the water forms a closed loop between the breeding pond, the filtrate bed and the planting tank.

2. Open-loop mode: there is no closed-circuit circulation between the breeding pond and the planting trough (or bed), and the wastewater discharged from the breeding pond is used as one-time irrigation water to directly ** vegetable planting system without forming a return flow, and only new water is added to the breeding pond each time. This model can be used in places where water sources are abundant.

There are many reasons for the unsuccess, it may be that the proportion of fish and vegetables is not appropriate, this can be consulted Wuhan Double Helix Biotechnology****.

What is the function of the aquaponics system? What else.

Hello, dear, I am glad to answer for you: the aquaponics system should have the following functions: 1. Continuous and efficient.

The substrate-cultured aquaponics system is always in operation and the production process is not interrupted, so the system produces fish and vegetables continuously. At the same time, it also has ecological food services, popular science propaganda activities, and joint research with universities, which is an efficient production model. 2. Save energy.

It is different from traditional aquaculture in that there is no water pollution, so there is no need to change the water frequently and extensively. The system itself is a closed-loop production system, and there is no depletion of water in the system except evaporation. Because the water is self-circulating throughout the system, there is no need to replace the water all the time, and the water utilization rate reaches more than 90%.

The fish pond is in a greenhouse, and the pond can store energy from the sun during the day and release it at night. Therefore, in the aquaponics greenhouse, it is cooler than the ordinary greenhouse during the day and warmer than the ordinary greenhouse at night, forming a miniature marine climate, saving a lot of energy required for heating the greenhouse and saving a lot of electricity consumption. The establishment of aquaponics system can greatly alleviate the dilemma of land use, because the whole production process is very small dependent on land, does not need to occupy too much land, saves land, and at the same time, can also avoid many native diseases.

Therefore, the aquaponics system is a production system that saves water, electricity and land. 3. High-quality output. Through the analysis of the output capacity of the aquaponics system, it can be seen that in the whole production process of the aquaponics system, there is no need to use fertilizers and pesticides, and the growth of fish and vegetables depends on the continuous flow of water in the system.

The high quality of fish and vegetables is guaranteed through the action of microorganisms. In the modern society that pursues food safety and green GDP, this completely self-sufficient system is indeed a sustainable production model that is well worth promoting.
