Description

A kind of microbial water-purifying agent for loach breeding water and preparation method thereof
Technical field
The present invention relates to a kind of microbial water-purifying agent and preparation method thereof, particularly relate to a kind of microbial water-purifying agent for loach breeding water and preparation method thereof.
Background technology
In recent years; the quick propelling of high-efficiency agriculture; special aquaculture industry is developed swift and violent; the new, special products of famous brands, of extra fine quality aquaculture kinds such as river crab, freshwater shrimp, Procambius clarkii, Macrobrachium rosenbergii, Penaeus vannamei, Trionyx sinensis (Wiegmann), mandarin fish, perch, river Puffer, swamp eel, loach have reached the level of large-scale production, define the feature of self.
Loach is called as " ginseng in water ", all has the distribution north uncommon but the various places that also distribute in southern china various places.The whole year all can gather, and summer is maximum, and be a kind of fish that nutritive value is very high, it is not identical with other fish, no matter appearance, and the bodily form, life habit is all different, is a kind of special bullhead.Loach likes the bottom inhabiting hydrostatic, often haunts the mud top layer being rich in canebreak bottom lake, pond, irrigation canals and ditches and paddy field, strong to environment-adapting ability.Life water temperature 10-30 DEG C, optimum water temperature is 25-27 DEG C.When water temperature in winter drops to below 5 DEG C, namely pierce 20-30cm in mud and survive the winter depths.Loach is many out preys on planktonic organism, aquatic insect, crustacean, Aquatic Higher Plants chip and algae etc. at night, sometimes also absorbs water-bed humus or body refuse.Namely loach 2 reaches maturity age in winter, starts annual April to breed (water temperature 18 DEG C), lays eggs in the shallow water thick grass of water depth deficiency 30 centimetres, and the ovum grain of output sticks to pasture and water or above the drought grass that do not had by water logging.The prelarva hatched, often disperses life, does not form colony.
Propagate loach artificially, the food species of throwing something and feeding has fly maggot, fish meal, Swine blood meal, dried silkworm chrysalis meal, rice bran, wheat bran, dish cake etc.Because the density of cultivation is considerably beyond natural level, water body cannot process the movement of unnecessary bait and loach, causes water body contaminated, and dissolved oxygen declines, and ammonia nitrogen index raises, and has a negative impact to the growth of loach.In current cultural technique, because enforcement process cannot be carried out to aquaculture water, easily cause the rising of loach sickness rate, survival rate reduction, the problems such as production declining.Conventional settling mode is that certain interval of time carries out changing water treatment, but changing water improves production cost on the one hand, and what also easily cause loach on the other hand is not suitable with symptom.
Summary of the invention
Herein for above shortcomings in existing cultural technique, one of technical problem to be solved by this invention is to provide a kind of preparation method of microbial water-purifying agent of loach breeding water.
Two of technical problem to be solved by this invention is to provide a kind of microbial water-purifying agent of loach breeding water, adopts aforesaid method to be prepared from.
Technical problem to be solved by this invention, is achieved by the following technical solution:
For a preparation method for the microbial water-purifying agent of loach breeding water, be made up of following step:
(1) magnetic silicon ball of 30-50 weight part finishing alkyl chain is joined in the water of 300-500 weight part;
(2) under 2-10 revolutions per second of agitation condition, add 100-150 weight part microorganism reagent, described microorganism reagent is made up of following weight parts component: Rhodopseudomonas palustris (Rhodopseudanonaspalustris) 60-80 part, Synechococcus (Synechococcus) 60-80 part, nitrated coccus (Nitrococcus) 10-30 part, Nitrobacter winogradskyi (Nitrobacterwinogradskyi) 20-40 part, Pseudomonas aeruginosa (P.Aeruginosa) 20-30 part, Paracoccus denitrificans (Paracoccusdenitrificans) 10-20 part, Beggiatoa (Beggiatoia) 3-5 part, thiobacillus (Thiobacillus) 3-5 part, ciliate (Ciliate) 30-60 part, plantlike flagellate (Phrtomastingina) 30-60 part, Dunaliella salina (Dunaliella) 30-50 part, chlorella (Chlorella) 30-50 part,
(3) cultivate 20-30 hour under adding 60-100 weight part beef extract-peptone nutrient agar normal temperature again, the microbial water-purifying agent for loach breeding water of the present invention can be obtained.
Preferably,
In step (1), the magnetic silicon ball of described finishing alkyl chain is the magnetic silicon ball of surface finish C 8 alkyl chain and/or the magnetic silicon ball of finishing C18 alkyl chain.
The magnetic silicon ball of surface finish C 8 alkyl chain, specifically can adopt the method disclosed in Chinese invention patent CN101185874A embodiment 1 to be prepared.
Further, the magnetic silicon ball of described finishing alkyl chain is the magnetic silicon ball of surface finish C 8 and C18 alkyl chain, adopts following method to be prepared from:
(1-1) water heat transfer Fe is used 3o 4magnetic nano-particle: by 1 gram of FeCl 36H 2o, is dissolved in 30ml ethylene glycol, and add 4 grams of anhydrous sodium acetates, temperature of reaction is 200 DEG C, and the reaction times is 12 hours, generates Fe 3o 4magnetic nano-particle;
(1-2) by above-mentioned Fe 3o 4magnetic nano-particle washes with water, and removing water-soluble impurity, is then dispersed in 10g water, obtain dispersion liquid A, get centrifuge tube, add the above-mentioned dispersion liquid A of 3g, add the ultrasonic 8min of 5ml2MHCl solution, be separated the green clear liquid of removing with magnet again, then use 10ml water-dispersion, then collect particle with magnet, remove light green clear liquid, with the citric acid three sodium solution ultrasonic disperse of 5ml10wt%, leave standstill 2h, again obtain dispersion liquid B with after 5ml water-dispersion;
(1-3) get above-mentioned dispersion liquid B1g, after 5ml water and 30ml alcohol dilution, then add 20wt% ammoniacal liquor 0.5ml, ultrasonic disperse 10 minutes, stir, add 1ml tetraethoxy, stirring at room temperature 12 hours, collect with magnet, washing, dry, obtain complex microsphere;
