Impervious membrane ponds have broad development prospects in soilless ecological farming of rice field eel

      Aquaculture integrated planting and breeding technology is a new ecological sustainable agricultural technology involving fish and plant nutrition, physiology, environment, physics and chemistry. It is a comprehensive planting and breeding model aimed at the eutrophication of aquaculture water bodies. Based on the principle of ecological symbiosis, it uses the symbiosis and complementarity of fish and vegetables to organically combine aquaculture and vegetable cultivation, and carry out substances in the fish and vegetable ecosystems in the pond. Recycling, to achieve a comprehensive planting and breeding model of fish without changing water, vegetables without fertilizing, and resource recycling.  

     The main features include: 

     1. Integrate fish and vegetables. Vegetables can be grown in fish ponds.

     2. Ecological complementarity. A cyclic system of fish fertilizer and water-vegetable water purification-water fish breeding is formed in the pond. 

    3. Environmental restoration. Repair and protect the pond water environment and alleviate the eutrophication of the pond water body.

    4. Energy saving and emission reduction. Especially in the summer high temperature season, it can effectively reduce the water consumption for planting, solve the problem of difficult water exchange in water-scarce areas, reduce irrigation costs, and realize energy saving (water) emission reduction. 

   5. Double water collection. Make full use of pond water resources, use fish manure as a nutrient source for vegetable growth, improve the quality of aquatic products, produce green vegetables, and improve overall production efficiency. Anti-seepage membrane pond soilless ecological breeding, land reclamation is the best, the pond construction cost is low, maintenance is convenient, and the use value of a single labor is high;

     It is easy to observe, change the water, dredge thoroughly, maintain the water quality for a long time, and the fish pond does not need to be dealkalied and disinfected. The impermeable membrane is non-toxic, environmentally friendly, fast construction speed, good chemical stability, resistance to plant root penetration, high impermeability coefficient, anti-aging, anti-ultraviolet, strong anti-decomposition ability, good plasticity, and its general service life is 8 years. The wall of the impermeable membrane is smooth and will not cause mucosal damage to the surface of the fish. When pests and diseases occur, it is convenient to observe and take measures in advance. There is no dead corner when spraying, and the effect of disease prevention is good. Overcoming the difficulties of overwintering and management, it is beneficial to prolong the feeding period of the rice field eel, and the fishing is completely convenient. Soilless ecological farming of rice field eel in impermeable membrane ponds has broad development prospects, with good investment, income and benefits, and provides a new and efficient way to explore the comprehensive utilization of hydroponics.
