Abstract
The invention discloses a method for microcystis algae bloom treatment in an earth pond cultivation process. The method includes the steps: 1) when algae bloom happens, closing an automatic aerator, blowing the microcystis algae bloom to downwind positions by the aid of wind force, and using a screen to fish microcystis algae bloom frond floating on the water surface; 2) mixing bacillus inoculant with brown sugar by adding water, soaking the bacillus inoculant and the brown sugar into water for one night, then splashing the mixture into the whole pond for once a day and continuing for 2-3days; and 3) adding inoculant of photosynthetic bacteria into the mixture, splashing the mixture into the whole pond for once a day and continuing for 2-3days. Probiotics are used for absorbing and converting eutrophic substances in water and competing nutrients with microalgae so as to inhibit reproduction of microcystis algae; and bacteria in waters lyse the microcystis algae and decompose and convert microcystin timely, so that cultivation water quality stability is maintained, shrimp diseases can be effectively prevented, survival rate and yield of culture species are increased, and economic benefit is increased.
Description
Technical field
The present invention relates to a kind for the treatment of process of wawter bloom, be specifically related to the treatment process of microcystis waterbloom in the native pool cultivated process.
Background technology
In the last thirty years, body eutrophication and the harmful little algae wawter bloom that causes have thus become the great environmental problem of global concern, the formation of wawter bloom and decay and brought a series of serious consequences to the aquatic ecosystem, cause transparency to reduce, sharply change the physicochemical character of water body, water body distributes stench, periodically anoxic, most aquatic animal,plantses are dead, and species diversity descends.Wherein Microcystis aeruginosa can produce Microcystin, and this toxin is to occur the widest a kind ofly in the cyanophycean toxin, has the multiple toxic actions such as liver toxicity, renal toxicity, neurotoxicity.The hydrocoles that causes because of Microcystin both at home and abroad, birds, domestic animals even human dead event frequent occurrence.Microcystis aeruginosa is blue-green algae kind common in the pond, and microcystis waterbloom has a strong impact on healthy growth and the disease resistance of aquaculture organism.
The control microcystis waterbloom not only can keep cultivation water stable, and optimization of ecological environment can also prevent the disease of aquaculture organism to occur.
Summary of the invention
The treatment process that the purpose of this invention is to provide microcystis waterbloom in the pool cultivated process of a kind of soil.
The technical solution adopted in the present invention is:
The treatment process of microcystis waterbloom comprises the steps: in the pool cultivated process of soil
1) when wawter bloom occurs, closes oxygenating machine, utilize wind-force that microcystis waterbloom is blown to place, lower air port, salvage the microcystis waterbloom frond that swims in the water surface with 300 purpose bolting silk nets;
2) gemma bacillus agent and brown sugar are added water and mix and soak a night, the full pond of then splashing, is used in conjunction 2-3 days at every day 1 time;
3) add simultaneously with the photosynthetic Bacteria agent full pond of splashing, every day 1 time, be used in conjunction 2～3 days.
Step 2) in, be 10,000,000,000/g by viable bacteria amount in 1 meter of the pond depth of water, the gemma bacillus agent, the gemma bacillus agent consumption is 1～2kg/ mu, and the brown sugar consumption is 2kg/ mu.
In the step 3), be 500,000,000/ml by viable bacteria amount in 1 meter of the pond depth of water, the photosynthetic bacterium microbial inoculum, photosynthetic bacterium microbial inoculum consumption is 2～3L.
Beneficial effect of the present invention is:
Treatment process of the present invention utilizes probiotics to absorb the rich nutritive material that transforms in the water, with little algae competition nutrition, thus the breeding of inhibition Microcystis aeruginosa; Bacteria lysis Microcystis aeruginosa in the while water body, in time the decomposition and inversion Microcystin keeps cultivation water stable, can effectively prevent the generation of aquaculture organism disease, significantly improves surviving rate and the output of cultivation object, the increase economic benefit.
Embodiment
The present invention is further illustrated below in conjunction with embodiment, but be not limited to this.
The viable bacteria amount of used gemma bacillus agent is 10,000,000,000/g among the following embodiment, by subtilis and and the Bacillus licheniformis kind press product after the 1:1 mixed fermentation.Used photosynthetic bacterium microbial inoculum is Rhodopseudomonas palustris, and raw material specification is 500,000,000 cfu/ml.Used microbial inoculum all can obtain in the market buying.
Embodiment
Carrying out prawn culturing in cultivation base, Maoming City Dianbai between year January in October, 2011 to 2012 tests.5 mu of cultivating pool areas, depth of water 1.5-1.8 rice, putting seedling density is 50,000 tail/mus.
The cultivation beginning is in the time of 16 days, and Microcystis aeruginosa breaks out, and causes wawter bloom.At first, close oxygenating machine, utilize wind-force that microcystis waterbloom is blown to place, lower air port, salvage microcystis waterbloom with 300 mesh sieve tulles.Then, getting the viable bacteria amount is the gemma bacillus agent 15kg of 10,000,000,000/g, and brown sugar 10kg adds water 20kg mixing and soaks a night, the full pond of then splashing, and lower air port microcystis waterbloom accumulation area, the bacterium liquid of splashing doubles, and once a day, is used in conjunction 3 days.When using genus bacillus, add the full pond of splashing with the photosynthetic bacterium microbial inoculum 15L that contains viable bacteria amount 500,000,000/ml, purifying water body once a day, is used in conjunction 2 days.After 3 days, microcystis waterbloom disappears.
During cultivation to 74 day, microcystis waterbloom occuring again one time, still adopts present method successfully to process.
Results prawn when cultivating 110 days, prawn body weight 12-14g/ tail, 1002 jin of per mu yields, surviving rate is 80.16%.The cultivating pool that blue-green algae is broken out in the locality then cultivates failure.
