The Chinese aquaculture industry has been rapidly developed in the last 30 years, the total yield of the Chinese aquaculture in 2018 exceeds 5000 ten thousand tons, the total yield of the Chinese aquaculture accounts for more than 78 percent of the total yield of the Chinese aquaculture, and the method is the only main fishery country in the world in which the total amount of the cultured aquatic products exceeds the total amount of fishing. While these brilliant achievements are achieved, the quantity and quality of the aquaculture industry in China are unbalanced, the quality benefit is not developed sufficiently, and the main contradiction of the fishery industry in China is more and more prominent, which mainly reflects the contradiction between the demand of people on high-quality safe aquatic products and ecological environment of graceful water areas and the structural contradiction of aquatic product supply, and the contradiction between the fishery industry and the over utilization of resource environment. These major conflicts present a significant challenge to the sustainable development of the aquaculture industry. The cultivation is water cultivation, and the good water quality ensures the high quality of aquatic products. In recent years, the heat of biological floccule culture is increasing, and the biological floccule culture can meet the basic requirements of water saving and water treatment of two aquaculture at the same time, so that the biological floccule culture is always concerned by the aquaculture industry. On one hand, bacteria in the biological floc convert culture self pollutants such as nitrogen, phosphorus and the like into mycoprotein, so that harmful substances such as ammonia nitrogen, nitrite nitrogen and the like are reduced, and a water body is purified. On the other hand, organic debris, residual bait, excrement and the like generated in the culture process can be adhered and gathered into a part of biological floccules through bacteria and enter a food chain of cultured organisms, so that the recycling of substances is improved, and the feed coefficient is reduced.
At present, in domestic biological floc culture, the breeding of water microorganisms is stimulated mainly by means of proper overfeeding of baits to form flocs, a stable biological floc system needs to consume a certain time to greatly reduce culture efficiency, and the time for waiting for the formation of the biological flocs is greatly shortened by adopting floc inoculation and carbon source activation. In addition, after the biological floccule system is formed, the excessive microorganisms can bring burden to the culture system, and if the microorganisms are not adjusted in time, the culture yield can be reduced.
The scale of Chinese saline-alkali soil is large, most of the soil is seriously salinized, and grain plants such as rice, wheat and the like are difficult to grow in the saline-alkali soil. In addition, the beach land can be covered and submerged by a large amount of seawater, and most of the beach land is in a waste state except for the growth of some red trees. The planted sea rice can not only make full use of saline-alkali soil and ocean beach to solve the grain problem, but also prevent wind and wave, promote siltation and protect the beach, fix bank and protect dike, purify seawater and air, and has the ecological and social value as mangrove forest.
Therefore, it is imperative to provide a device which can not only preserve and activate the biological floc, but also fully exert the water purification function of the biological floc. Meanwhile, the redundant biological flocs can also be used as planting fertilizer for sea rice, the soil quality is improved, and the device can also be combined with the ecological cycle breeding of sea rice, fish and shrimp to form an ecological saving type and environment-friendly type saline-alkali soil ecological cycle rice and shrimp breeding system.
