Use the water to grow vegetables to provide nutrients for vegetables, and after the vegetables purify the water, they can raise fish again, and the fish and vegetables form an ecological cycle relationship.
Recently, the aquaponics base invested and built by the District Agricultural Investment Group was officially put into use in Wuhan Weinong Seedling Co., Ltd.

Walking into the aquaponics base, the super large vat is shocking, and the fish fry are wandering happily in the breeding bucket with a diameter of 8 meters and a height of 1.5 meters.
Duan Shiqi, the person in charge of the base, introduced that the aquaponics system is an ecosystem integrating the cultivation of vegetables and grains and other crops and fish farming, and combined with modern computer control technology, the automation and intelligence of aquaponics management is realized. Fish excrement provides abundant nutrients for the growth of vegetables, and the purified water can be returned to farming water.
○Aquaponics base microbial pond.
The base first extracts groundwater and stores it in the raw water tank, and the raw water is filtered by a microfilter into the microbial pool, and then enters the breeding tank after passing the brush and biochemical ball cleaning, ultraviolet sanitizing and other processes, and meets the water use standards. The 16 breeding barrels in the base are connected by underground pipelines, and the breeding barrels are equipped with aeration water pushers, which can accelerate the flow of water in the barrels and prevent water from deteriorating and smelling.
Fish farming water contains residues such as fish manure and bait, as well as rich nutrients such as nitrogen, phosphorus, and potassium that vegetables need. The fecal sewage collector uses the siphon principle to discharge the fish feces, and then, the rotary drum microfilter and microbial reactor are put on the field to physically filter and biological the water, and the underground pipeline will send the purified fish water to the vegetable planting area.
○Eggplant in the vegetable growing area grows vigorously.
The vegetable planting area is only separated by one door from the breeding area, and 14 rows of lettuce, cabbage and other fast lettuce cultivation beds stand side by side, and the fish farming water comes in handy here.
The tail water of planting vegetables enters the return tank, and then goes through the processes of filtration, purification, ultraviolet sterilization, etc., and after meeting the breeding conditions, it is circulated to the breeding barrel again to complete the cycle.
Duan Shiqi calculated that compared with the traditional planting and breeding methods, the economic and ecological benefits of the aquaponics system have been greatly improved.
Traditional earthen pond fish farming, one acre of fish pond can breed up to 3,000 catties of perch, the water consumption is 1,000 tons, and a diameter of 8 meters of aquaponics breeding barrel only needs 80 tons of water, can breed 5,000 catties of perch. Fast lettuce such as lettuce and cream cabbage can increase the growth rate by 10%. The base only needs to replenish water 4 times a month, and can harvest 1.5 stubble of fish and 10 stubble of vegetables a year.
There is no need to change the water frequently, there is no need to fertilize the vegetables, waste discharge is minimized, and the taste of fish and vegetables grown up on "natural ingredients" is better.
High-tech figures can be seen everywhere in the aquaponics base.
In the control room of the base, the staff turned on the aquaponics smart Internet of Things system, and the water temperature, pH value, dissolved oxygen, nitrite and other parameters appeared on the large screen instantly, and the camera could also monitor the status of the fish in the water.
○ A variety of high-tech applications are applied to the vats in the breeding area.
Duan Shiqi introduced that the intelligent system has the functions of mobile water quality inspection, aeration linkage control, growth analysis, micro meteorological early warning, big data water quality analysis, etc., and sensors and cameras are installed in each breeding barrel to monitor and control water quality in real time.
When the reporter was interviewing, the system alarm sounded. It turned out that the high temperature caused the dissolved oxygen in the water to be low, and Duan Shiqi immediately turned on the aerator with one button on his mobile phone.
"When the sensor information is abnormal, the system immediately sends an alarm to the networked mobile phone." Duan Shiqi introduced that the aquaponics Internet of Things system is equipped with remote communication functions, and the water flow speed, water temperature, bait feeding speed, feeding amount, oxygenation, water replenishment, ventilation and so on can be controlled through the driving device.
○You can set the automatic feeding time from your mobile phone.
Just when it was feeding time, the reporter saw that the intelligent feeding machine moved to the top of the breeding barrel at a constant speed through the electric track in the breeding area, and the bait was dropped, and the fish flocked to it.
The aquaponics smart IoT system can provide automatic services throughout the day, which reduces manpower input, reduces labor intensity, and can reduce fish mortality and increase income.
"Aiming at the needs of traditional industries, we will promote the upgrading of traditional industries with new quality productivity." According to the relevant person in charge of the District Agricultural Investment Group, in the future, famous fish such as mandarin fish and tilapia will be cultivated in the aquaponics base, and special vegetables such as bitter chrysanthemum, arugula, and cream cabbage will be planted to further increase the output value through scientific and technological empowerment.
In addition, the District Agricultural Investment Group will also integrate resources such as plant factories, edible fungus planting bases, and seedling cultivation bases, jointly carry out industry-university-research projects, make concerted efforts to tap new agricultural productivity, and promote the high-quality development of agriculture in Dongxihu District.
