We'll check the vegetables
On 24 august, a row of “back-to-back” pipes was lined up in the vegetable production shed of the co-operative fish and vegetable co-operative experiment base at the east guannan village in su shui town. On the pipeline, green oil has a good growing vegetable. The head of the base was tied to see how vegetables were growing. It was easy to see him go to a sap of cabbage and pull it up, with no dirt on it but with water. On the other side of the base, in a clear pool, the fish swam and swam, the technician zhang kaisa had a fish feed and the fish competed for fish。
In june this year, cacs invested $1. 5 million in the introduction of symbiotic techniques for fish and vegetables and the establishment of a test base for symbiotic fish and vegetables in areas of past pig farms. Here, fish are not changed, food is not fertilized, and the secret is co-symbiosis. It is described as the water that feeds the fish, which is filtered on several occasions, can be grown directly into vegetables, the water that grows the vegetables can be extinguished and fish can be recycled to achieve a “one-water double harvest”。
Fish farming at the symbiotic test base is in a large pool of approximately 3 metres in diameter, where some 28,000 tails are grown, such as catfish, plasterfish, silver cod and duckfish. There is a pipe next to the sink, and the source of clean water in the tube continues to flow into the pool. "the water that comes out here is clean water that is absorbed through vegetables and wiped out." and it says, "put on." so, the leash came to a device, and the water flowing from the fish pool was concentrated in a big pond, “this is our first physical filter pool, which is physically filtered and then transferred to the biofiltration pool, before growing the fungus”. The treated water can then be used directly for breeding and growing vegetables。
Vegetable sheds, where filtered water flows into “back” pipes for growing vegetables. Pipelines grow one vegetable every 15 centimetres. Vegetables such as cabbage, celery, cabbage, cucumbers and guacamole are also very lively and green. “the water in the pipe contains fish excreta and artificially grown fungi, which are natural fertilizers, and the roots of plants are immersed in water 24 hours a day, so that nutrients are well absorbed.” chengcai said, “when plants absorb the nutrients in the water, the water flows back into the water tank where the uv is extinct. After extinction, the water flows back to the fish pool and continues to feed the fish.”
In june this year, after the cooperative had established a symbiotic test base for fish and vegetables, a “first bucket of water” for fish farming was introduced from deep wells. The water is efficiently recycled, feeding fresh and high-quality freshwater fish that are scarce in the local market, and growing non-hazardous vegetables to achieve “one-water double harvest”. In addition, after the start of the symbiosis project, through the recycling of water resources, the base needs only a small amount of water per day, and effluents can be used to refill the field's vegetables. In order to ensure the quality of fish and vegetables, the leash also provides regular sampling of water quality and fish meat. “at present, this technique is in the pilot phase, with statistics to be prepared for the next expansion.”。
In order to further increase the efficiency of farming and planting, a thermo-control system has been installed to ensure that water temperature is stabilized at around 20 degrees celsius. “now, the first seedlings have grown to about half a pound each, and the vegetables in the shed are well grown. At this rate, the fish we raise can be sold half a year, year round. Vegetable production is estimated at 10 tons per year and fresh water fish production at 30,000 kilograms.” in the future, the twinning programme will continue to scale up fish and vegetables, further stretching available resources, boosting industry efficiency and boosting local villagers ' incomes。
