Abstract
The invention discloses a prevention and control method for blue-green algae in aquatic water. Prevention and control for blue-green algae can be realized through algae removal, detoxification to improve water, water exchange and complete water improvement. The method disclosed by the invention can effectively kill and remove the blue-green algae and also realize the protection and control functions; furthermore, the quality of the water is improved; the blue-green algae cannot be over-bred, so that outbreak of the blue-green algae can be avoided; moreover, the growth of aquatic organisms in the water cannot be affected during algae killing, prevention and control. The method disclosed by the invention is simple in design, convenient to operate, high in feasibility, low in cost, easy to popularize and suitable for large-area water.
Description
Technical field
The present invention relates to the preventing control method of a kind of blue-green algae, be specifically related to the preventing control method of blue-green algae in a kind of aquaculture water.
Background technology
Blue-green algae is a kind of waterplant, and the amount reproduction of blue-green algae worsens ventilation and the illumination condition of aquaculture water, suppresses growth and breeding, the photosynthesis of beneficial organism in water body.The toxin that blue-green algae produces is healthy by approach harm animal and human bodies such as oral cavity, respiratory system, skin contact and blood penetration.The secondary metabolites of toxin makes the variation of hydrocoles ovum, behavior growth failure, containing toxin Cells of Blue-green Algae, in water body, move, after preying on clay co-precipitation or by hydrobiont, with its movement precipitation etc., toxin accumulated and be trapped in water-bed matter, causing the vicious cycle of water body.
In aquaculture water, the reason of blue algae bloom is mainly as follows: 1. temperature: because being subject to the restriction of other algal grown, blue-green algae also can not be broken out under normal temperature condition, during 25 ~ 35 ℃ of water temperatures, the speed of growth of blue-green algae can be faster than other algal grown speed, therefore temperature is one of principal element of blue algae bloom.2. rich battalionization is supported: aquaculture water eutrophication, and blue-green algae ratio is easier to growth, and the eutrophication of aquaculture water is the origin cause of formation of outburst blue-green algae.3. organophosphorus: organophosphorus is the necessary factor of blue algae growth, administer blue-green algae the most basic way be to remove organophosphorus.
Present common blue algae control method has a variety of, but most of improvement method is all upper improvement endways, is the very unwise move of curing the symptoms, not the disease, and there is no good control effect.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of method more reasonable, the method for the prevention and control blue algae bloom of strong operability.
Technical problem to be solved by this invention realizes by following technical scheme, the invention discloses the preventing control method of blue-green algae in a kind of aquaculture water, is characterized in, its step is as follows:
(1) sterilizing: first the water body in culturing pool is down to 1 meter, to the mixture aqueous solution of evenly splashing and containing 14-16 gram of large ring lactone antibiotic compounds and 480-520 gram of salt in the water body of every mu of culturing pool;
(2) removing toxic substances, after modify-water: 12-48 hour, makes potassium aluminium sulfate amidin with the water dissolution potassium aluminium sulfate powder of 300 times of weight, full pool spilling head, and the potassium aluminium sulfate wherein using in every cubic metre of water body is 0.4-0.6 gram;
(3) change water: after 12-48 hour, extract the water in culturing pool out 18-25%, inject the clear water of same amount, then to applying the phosphate fertilizer that bio-fertilizer and major ingredient are calcium superphosphate in culturing pool, the transparency that makes water is 15-35cm, the bio-fertilizer wherein using in every mu of water body is 1-2kg, and the phosphate fertilizer using in every mu of water body is 1.2-1.6kg; After 12-48 hour, throw in bacterium Pu Kang again in water body, the bacterium Pu Kang using in every mu of water body is 3-6 gram;
(4) thoroughly after modify-water: 12-48 hour, be evenly spilled into Sulfothiorine again in the water body of culturing pool, every 10 days repeat to be spilled into 1 time, and the Sulfothiorine wherein adding in every cubic metre of water body is 1.2-1.6 gram.
The main body of bio-fertilizer of the present invention is that biological fermentation is fertile, every gram is not less than 3,500,000,000 containing probiotics number, be characterized in, in 1-2 days inherent water bodys, turn out a large amount of useful algae and planktonic organism, can suppress the generation that the growth of harmful algae such as moss, blue-green algae and soil infect disease.Bio-fertilizer of the present invention is any bio-fertilizer that meets above-mentioned requirements disclosed in prior art, that sell.Such as Nanjing Jin Nannong Bioisystech Co., Ltd, address: No. 3, west, Industrial Zone, Tang Shan street, Jiangning District, Nanjing, phone: 025-52644608, the loose strong product of commodity Jin Nannong by name that this company produces.
Phosphate fertilizer of the present invention be disclosed in prior art, sell anyly contain the phosphate fertilizer that major ingredient is calcium superphosphate.
Bacterium Pu Kang of the present invention is trade(brand)name, its manufacturer is Nanjing Jin Nannong Bioisystech Co., Ltd, bacterium Pu Kang is comprised of Bdellovibrio, genus bacillus, photosynthetic bacterium three bacterium unifications, viable count reaches more than 1,000 hundred million/gram, it acts synergistically, the mutually sharp interpromoting relation in five elements synergy of many bacterial classifications, and stability is high, can purify water, water transfer removing toxic substances.
Technical problem to be solved by this invention is to realize by following technical scheme, its step is as follows: (1) sterilizing: first the water body in culturing pool is down to 1 meter, to the mixture aqueous solution of evenly splashing and containing 15 grams of large ring lactone antibiotic compounds and 500 grams of salt in the water body of every mu of culturing pool;
(2) removing toxic substances modify-water: after 24 hours, with the water dissolution potassium aluminium sulfate powder of 300 times of weight, make potassium aluminium sulfate amidin, full pool spilling head, the potassium aluminium sulfate wherein using in every cubic metre of water body is 0.5 gram;
(3) change water: after 24 hours, extract the water in culturing pool out 20%, inject the clear water of same amount, then to applying the phosphate fertilizer that bio-fertilizer and major ingredient are calcium superphosphate in culturing pool, the transparency that makes water is 15-35cm, the bio-fertilizer wherein using in every mu of water body is 1.5kg, and the phosphate fertilizer using in every mu of water body is 1.4kg; After 24 hours, throw in bacterium Pu Kang again in water body, the bacterium Pu Kang using in every mu of water body is 5 grams;
(4) thoroughly modify-water: be evenly spilled into Sulfothiorine again in the water body of culturing pool after 24 hours, every 10 days repeat to be spilled into 1 time, and the Sulfothiorine wherein adding in every cubic metre of water body is 1.5 grams.
Technical problem to be solved by this invention is to realize by following technical scheme, and before step (2) operation, after 12-48 hour, repeating step (1) once.
Compared with prior art, the method that the present invention uses can effectively be gone out except blue-green algae, has again the effect of prevention and control simultaneously, and improved Water quality, blue-green algae can excessive multiplication, thereby can not form Blue-green Algae Fast Growth, can not affect the growth of the aquatic living things in water body when algae removal prevention and control in addition.
The inventive method simplicity of design, easy to operate, feasibility is high, and cost is low, easily promotes, and can be applicable to using large-area waters.
