Special biological fish-fertilizer for aquaculture and preparation method thereof

Abstract

The invention discloses a special biological fish fertilizer and a preparation method for the fertilizer used in aquiculture; wherein, the biological fish fertilizer mainly comprises raw materials as follows: microbiological preparation, inorganic fertilizers, fermentation organics, micro-mineral amino acid chelate, mineral composites, and water quality improver. The preparation method for the special biological fish fertilizer in aquiculture comprises steps as follows: microbiological preparation is produced; fermentation organics is then produced, and the micro-mineral amino acid chelate is produced, eventually the finished products are made. The special biological fish fertilizer has the advantages of limiting the growth and reproduction of the harmful algae, promoting the large-scale growth and reproduction of the suitable food for fish, effectively improving the water quality and purifying the water environment, strengthening the fish immunity, reducing the diseases, reducing cost due to the small use level, convenient use, mild odor, no pollution to the water, and environment protection. By combining the modern bioengineering technique, low-temperature drying technique, spray-drying technique, and super-fine crushing techniques, the preparation method has the advantages of stable quality for the fish fertilizers and lower overall cost.

Description

Technical field [0001] The invention relates to a special biological fishery fertilizer for aquaculture, and also relates to a preparation method of the biological fishery fertilizer. The biological fish fertilizer is an efficient and environmentally friendly fish fertilizer, suitable for the breeding of silver carp, silver carp, tilapia, crucian carp, eel, carp, bream, various shrimps, shellfish, and the cultivation of various aquatic economic plants , Various breeding fish, shrimp and crab seed production; applicable waters include breeding ponds, lakes, reservoirs, rivers, tidal flats, small ornamental fish breeding ponds and other aquaculture water bodies. Background technique [0002] There are currently three main types of fertilizers used in the aquaculture industry, namely traditional organic fertilizers, inorganic fertilizers, and a kind called "enzyme bacteria biological organic fish fertilizer". Traditional organic fertilizer has its advantages, but the fertilizer effi...

Problems solved by technology

In addition to single-function organic fertilizers and inorganic fertilizers, since the 1980s, "formula fertilization", that is, "organic-inorganic compound fertilizers", has been promoted. Although compound fertilizers have absorbed the advantages of both organic and inorganic fertilizers, But their shortcomings are not well overcome

The existing single-type fish fertilizer and compound fish fertilizer also have a common shortcoming, that is, the chemical characteristics of the water body and the nutritional requirements of fish and their biological bait are not fully considered, and the ratio of macronutrients and micronutrients is unreasonable; Without the addition of probiotics, the natural circulation of organisms in the water body and the self-purification function of the ecological cycle of the water body are not fully utilized

The prior art also discloses a "High Efficiency Biological Fertilizer Formula and Manufacturing Method" (Chinese Patent Application Publication No. CN1238321A), although it also contains a small amount of beneficial microorganisms, there is no technical solution for adding inorganic fertilizers and trace elements. The technical purpose is to meet the nutritional requirements of different crops and various plants

There is also a disclosed "enzyme bacteria biological organic fish fertilizer and its production method" (Chinese patent application publication number is CN1757616), although it contains microorganisms such as enzyme bacteria and materials such as organic matter, inorganic fertilizer and trace elements, its nutrient element ratio Without considering the composition of various nutrient elements of fish and its bait organisms and the influence of the water environment on the utilization rate of various nutrient elements, the added trace elements are single and the amount is too large. In fact, the proportion of any nutrient element added is high. The lower limit, too low or too high will affect its utilization efficiency, especially the excess of trace elements, which will not only inhibit the absorption and utilization of macronutrients by aquatic organisms, but also produce toxic effects on aquatic organisms, inhibit their growth, pollute the water environment, and affect The food safety of fish; at the same time, there is no ultrafine grinding in the production process, which will affect the solubility of fertilizers and the utilization rate of fish bait organisms; only the addition ratio is set for conceptual substances, and there is no specific material The addition ratio, and there is no specific ratio of effective nutritional elements, lack of operability
