Background technology
Recent two decades comes, due to the development of intensive feeding cause, cause the sustainable growth of fish yield, wherein in cultivation, one of Main Yield-increasing measure of taking is (as the summer in suitable cultivation season, autumn) use urea to fishing pond at regular time and quantity, the nitrogen manure such as ammonium oxide and bicarbonate of ammonia, its effect is that fertilizer efficiency is high, can significantly increase filter-feeding freshwater fish, as silver carp, the planktonic growth that flathead is required, because pisciculture using chemical fertilizer has the effective feature such as pollution-free, particularly obtained universal and popularization rapidly in the freshwater aquiculture of China recent years at home and abroad.But long-term a large amount of chemical fertilizer that uses cultivates, and certainly will cause certain harm to the growth of fish, and the time has been grown meeting accumulation harmful element in fish body, thereby people are brought to certain harm.
At present a lot of plants adopt fertilizer, traditional fertilizer has its advantage, but shortcoming function singleness is longer by the process that plant plankton utilized, and in mineralisation process, consume a large amount of oxygen in water body, this in water to put product in a suitable place to breed as unfavorable in the growth such as fish; In addition, organic fish guano should be made base manure, and is mainly used in Winter-Spring water temperature lower season.And inorganic fertilizer function is comparatively single, although can make fish high yield, life-time service chemical fertilizer can bring many drawbacks, and contaminate environment is destroyed the eubiosis.
In fish farming process, in water body, can exist some to be unfavorable for the harmful bacteria of fish growth simultaneously, have a strong impact on the output of fish, thus in fish guano, add a certain amount of probiotics, effectively antagonism harmful bacteria, favourable to fish growth and breeding.Monistic compound fish guano can not be killed the harmful bacteria in fishpond at present, can not suppress the breeding growth of pathogenic bacteria in water body, therefore, lacks the effectively effect of control of fish disease.
Summary of the invention
The present invention is directed to the technical problem of current existence, a kind of microbial fish guano and preparation method thereof is provided, comprehensive nutrition is provided can on the one hand the growth of fish, can kill the harmful bacteria in fishpond on the other hand, suppress the breeding growth of pathogenic bacteria in water body, reduce the generation of disease, improve the yield and quality of fish.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of microbial fish guano, comprises the composition of following weight ratio: bacillus subtilis bacteria powder 2-4 part, enzymatic microorganism 1-4 part, solid photosynthetic bacterium 0.5-0.9 part, bacteriophagic Bdellovibrio 0.8-1.2 part, VITAMIN addition material 0.2-0.6 part, mineral substance addition material 10-16 part, sequestrant 0.2-0.4 part, Herba Eichhorniae 60-80 part, edible fungi residue 50-80 part, vinasse 100-110 part, fishbone powder 40-60 part, rice bran 70-80 part, brown sugar 10-16 part.
Described VITAMIN addition material component recipe ratio is: vitamin A, C, E mix with the weight ratio of 2:3:5.
Described mineral substance addition material is potassium primary phosphate 20-25%, monocalcium phosphate 10-15%, ferrous sulfate 2-5%, zinc sulfate 1-2%, manganous sulfate 0.8-1%, borax 0.3-0.5%, rose vitriol 0.03-0.06%, rare earth 0.2-0.6%, and all the other add salt to 100%.
Described sequestrant is that sodium humate and EDTA mix with the weight ratio of 1:1-2.
The preparation method of mentioned microorganism fish guano, comprises the following steps:
(1) first Herba Eichhorniae, edible fungi residue, vinasse are dried in the sun to water content below 40%, then add fishbone powder, rice bran, brown sugar according to described ratio, fully stir, mix;
(2) in said mixture, add bacillus subtilis bacteria powder and the enzymatic microorganism of having dissolved according to described ratio, then above-mentioned substance is inserted and in pond, mix corruption and macerate, plastics film on upper cap, carries out fermenting in advance for 3-5 days; Then plastics film is thrown off, and stir, allow mixture contact oxygen, temperature gradually raises, from normal temperature to 45 DEG C, keep continuing turning after 2-3 days, be then raised to 60 DEG C from 45 DEG C, the hold-time is 3-5 days, then cool the temperature to normal temperature, keep 7-10 days, until slaking is completely fermented complete;
(3) solid photosynthetic bacterium, bacteriophagic Bdellovibrio are dissolved in water, join in said mixture, stir;
(4), by above-mentioned fermented product, air dry in the sun, makes moisture content of material be less than 25%, then pulverize, pulverize fineness for by without screen pulverizer, after pulverizing, in material, add mineral substance addition material, sequestrant and VITAMIN addition material, mix and obtain microbial fish guano.
Described bacillus subtilis bacteria powder, enzymatic microorganism, solid photosynthetic bacterium, bacteriophagic Bdellovibrio is all finished products of buying.
The invention has the beneficial effects as follows:
(1) added that fish produce needed organism and inorganic mineral, trace element can provide comprehensive nutrition to the growth of fish;
(2) add subtilis, enzymatic microorganism and bacteriophagic Bdellovibrio, can kill the harmful bacteria in fishpond, suppressed the breeding growth of pathogenic bacteria in water body, reduced the generation of disease, improved the yield and quality of fish.
(3) added solid photosynthetic bacterium, the toxic substance such as nitrite, sulfide that can degrade in water body, and can restrain oneself the organic waste water of high density, the poisonous substance such as phenol, cyanogen is had and necessarily stood and capacity of decomposition, there is stronger decomposition and inversion ability, reduce the accumulation of toxic substance in fish body.
(4) these mushrooms that add can continue breeding in water body, expand survival rate, the balance that maintains microorganisms in water is had a very important role, and can regulate and adjust microecological balance in fish body enteron aisle, can also decomposer in the Harmful Residue, strengthen fingerling disease resistance.
