Problems solved by technology

Traditional organic fertilizers have the advantages of comprehensive nutrition, but the fertilizer effect is slow, consumes oxygen in the water body during decomposition and mineralization, the utilization rate is low, and it is easy to cause water pollution. The algae phase in the pond is single and miniaturized, and there are also problems such as affecting the quality of aquatic products; biological fish fertilizers and compound microecological preparations are currently the mainstream fertilizers for aquaculture, which can make up for organic fertilizers and inorganic fertilizers to a certain extent. Insufficient fertilizer, but there are also problems such as unbalanced nutrient ratio, slow fertilization, and short fertilizer effect

Embodiment 1

[0050] A method for preparing the above-mentioned compound high-efficiency biological fish fertilizer for aquaculture:

[0051] (1) Preparation of fermented product: after adopting livestock and poultry manure to raise leftovers after fly maggots and drying, add bacillus, saccharomycete, photosynthetic bacteria, fish meal, rice bran and after mixing, carry out aerobic turning over fermentation;

[0052] (2) Preparation of dried product: drying the fermented product of step (1);

[0053] (3) adding trace elements or trace elements and strengthening additives to the dried product obtained in step (2), stirring and mixing;

[0054] (4) Add ammonium chloride, urea, monoammonium phosphate and / or diammonium, superphosphate to the mixture obtained in step (3) and stir evenly.

Embodiment 2

[0056] A kind of preparation method of compound efficient biological fish fertilizer for aquaculture:

[0057] (1) Strengthen the preparation of chicken manure: select the chicken manure with a water content of 20-30% by mass, inoculate fly maggots and cultivate them for 7-10 days. After the fly maggots pupate, they are directly blown and separated, and the separated leftovers are dried until the water is 10-15% by mass percentage is enhanced chicken manure;

[0058] (2) Strengthen the preparation of pig manure: select water content to be 20-30% pig manure by mass percentage, cultivate 7-10 days after inoculating fly maggots, directly air blow and separate after fly maggots pupate, and the leftovers of separation are dried until the water is 10-15% by mass percentage is enhanced pig manure;

[0059] (3) Preparation of fermented product: take the enhanced chicken manure and enhanced pig manure of equal quality steps (1) and (2) respectively, and add bacillus, yeast, photosynth...

Embodiment 3

[0064] A method for preparing the above-mentioned compound high-efficiency biological fish fertilizer for aquaculture:

[0065] (1) select water content as mass percentage 20-30% livestock and poultry manure, cultivate 7-10 days after inoculating fly maggots, directly air blow and separate fly maggots after pupating, and the leftovers of separation are dried to moisture being 10-15% by mass % , after adding bacillus, yeast, photosynthetic bacteria, fish meal, rice bran and mixing, carry out aerobic turning fermentation: fermentation water supply is 20-30% mass percentage of the total material, oxygen supply, oxygen supply time is 50-60 hours in winter , 20-25 hours in summer, fermentation temperature 45-60°C, fermentation time 7-10d;

[0066] (2) drying the fermented product in step (1) at a drying temperature of 45-60° C., and drying until the water content is 15-25% by mass;

[0067] (3) adding trace elements or trace elements and strengthening additives to the dried produc...

Abstract

The invention relates to an aquaculture composite efficient biological fish fertilizer comprising the following ingredients by the weight: 10-12 parts of ammonium chloride, 8-10 parts of urea, 4-5 parts of monoammonium phosphate and / or diammonium phosphate, 12-14 parts of calcium superphosphate, 0.1-0.2 part of bacillus, 0.3-0.5 part of yeasts, 0.3-0.5 part of photosynthetic bacteria, 30-35 parts of dry enhanced livestock and poultry dung or the combination thereof, 4-7 parts of fish meal, 30 parts of rice bran and 10 parts of trace elements. The present invention provides an aquaculture new composite efficient biological fish fertilizer which is fast to fertilize, can maintain sustainable, can greatly increase the abundance of planktonic animals and plants and beneficial algae, enriches and balances the water nutrition, promotes the rapid growth of fish, improves fish quality and weight, and has obvious economic value.

Description

technical field [0001] The invention belongs to the field of biological fishery fertilizer, and in particular relates to a compound high-efficiency biological fishery fertilizer for aquaculture and a preparation method thereof. Background technique [0002] In aquaculture, the function of fertilization is to increase pond productivity, increase yield and benefit, mainly reflected in the following two aspects: one is fertilization to cultivate plankton, which can provide biological bait for aquatic animals and promote production increase; A large amount of planktonic algae can carry out photosynthesis, provide sufficient dissolved oxygen for the pond system, ensure the survival of aquaculture animals and maintain a good living environment. [0003] For algae, the substances that limit their growth are mainly carbon, nitrogen, and phosphorus. Among them, algae can directly use carbon dioxide in the atmosphere and water as a carbon source to synthesize organic matter, which mak...
