    Aquaponics

    First, the concept of aquaponics

    Aquaponics  (Aquaponics) is a novel compound farming systems, which the Aquaculture  (Aquaculture) and hydroponics (Hydroponics) both had completely  different farming techniques, through clever eco-design, to achieve a  scientific synergy Symbiosis in  order to achieve quality fish is not changing the water without  suffering, without fertilization and normal growth of vegetables  ecological symbiotic effect. In traditional aquaculture, as fish waste accumulation, ammonia water increases, gradually increase toxicity. In  aquaponics system, water is supplied to the aquaculture hydroponics  system, the microbial decomposition of the ammonia water into nitrite  and nitrate base, which was subsequently absorbed by plants as a  nutrient. Since  hydroponics and aquaculture technology is the cornerstone of aquaponics  technology, aquaponics by combining different modes of hydroponics and  aquaculture technology to produce various types of systems. Aquaponics allow animals, plants and ecological balance to achieve a  harmonious relationship between the three microbes, the future of  low-carbon production model of sustainable recycling-based  zero-emissions, agriculture is the most effective way to effectively  solve the ecological crisis.

    "Without watering vegetables, fish do not change the water," which is aquaponics! Just give the fish feed, you can do both.




    This is a closed loop of fish, vegetables and microorganisms created in a soilless environment. Fish  waste provides nutrients to plants, micro-organisms responsible for  decomposition of fish feces, providing nutrients, the plant after  absorption, is ecological water purification, fish to survive. No pesticides and fertilizers throughout the cycle, healthy and clean pollution-free, in line with modern healthy lifestyle.

    Second, aquaponics farming system model

    1,  blocking circulation pattern: pond water discharged via nitrification  microbial treatment bed, a circular manner into the vegetable  cultivation system, via biological vegetable root absorption after  filtration, wastewater treatment again returned to the pond, the water  in the breeding pool filtrate bed, planting groove formed between the three a closed cycle.

    2,  open-loop mode: to form a closed loop between the pond and the planting  groove (or bed), direct supply of vegetable planting system consists of  wastewater discharge ponds as disposable irrigation water without  forming a refund return, each time only to pond add new water. In the watered places you can use this mode.

    Third, aquaponics way classification

    1,  direct flotation: foam board and other floating body, directly to the  vegetable seedling planting plate fixed to floating water culture; this  approach is simple, but the utilization rate is not high, and some  omnivorous fish will eat roots problems, the need to be surrounded by a screen of root protection,  more cumbersome, and small cultivable area, efficiency is not high, the  density of fish should not be too large.

    2,  breeding and planting water separation system, the connection between  the two through the gravel bed nitrification filter design, aquaculture  wastewater discharge to the filter bed or via nitration (groove)  filtration, nitrification usually in bed biomass can be cultivated some  of the larger fruits plant, in order to accelerate the decomposition of organic nitrated material was filtered off. Via  nitration bed filtration relatively clean water is recycled into the  hydroponic vegetables or aeroponics vegetable production systems as a  nutritional solution or spray water cycle way supply vegetables root  absorption, absorption via vegetables and then returned again to the  pond to form a closed loop. This mode can be used for large-scale production, high efficiency, system stability.

    3,  direct connection with farming water irrigation systems in medium  culture, culture area waste emissions directly drip loop manner to a  substrate grooves or container cultivation, growing media after  filtration via wastewater collection again return farming water, this  pattern design more simple, direct connection with irrigation pipes planted tank or container to form a loop. Mostly  used for substrate cultivation fruits and other more tall plants, note  the place that the growing media must choose quality pea gravel or  ceramic-like size, good effect of these matrix filter, the filter will  not be overloaded and affect the water cycle, soilless cultivation should not use ordinary perlite, vermiculite or  waste WMLE matrix, these substrates due to poor drainage system easily  lead to the destruction of the ecological balance.

    4,  vegetables, aquatic systems, in this way as China's rice-fish farming  system, except that the breeding and cultivation separate symbiosis,  namely in cultivation plots covered with tarps, back filled back silt or  soil, and irrigation, Construction of the aquatic vegetable bed

    The  pond water is directly discharged farmland, and then return back to the  set called from the other end of the pond, so tarps lay in waste water  without leakage, and can fully aquatic vegetables filtration of waste,  to achieve the same good biological filtration , somewhat similar to the natural marsh system. Such as fish and wild rice stem symbiosis, symbiotic calla arrowhead  and other aquatic vegetables are the system design can be used.

    Aquaponics  technology is simple, practical and feasible, may be suitable for  large-scale agricultural production, it can also be used for small-scale  family agriculture hobby farms or cities, with broad prospects for  application. In  a particular practice operation, must be noted that the proportion of  fish and vegetables between dynamic adjustment, under ordinary  vegetables and conventional breeding densities, a general cubic meters  of water can produce 50 pounds of fish, while the supply of 10 square  meters of fruits and vegetables the fertilizer demand. Family  style aquaponics system, generally only 2-3 cubic meters of water  supporting vegetable cultivation area of 20-30 square meters, can  basically meet the 3-5 home vegetable production and fish consumption  needs, it is a very suitable for urban Countryside garden or farming mode of production, the main technology is the future trend of urban and agricultural development.
