Embodiment 1

[0022] Embodiment 1, a method for preventing and controlling cyanobacteria in a cultured water body, its steps are as follows: (1) Sterilization: first reduce the water body in the cultured pond to 1 meter, and evenly sprinkle the water body containing 14- The mixture aqueous solution of 16 grams of macrolide antibiotics and 480-520 grams of salt;

[0023] (2) Detoxification and water improvement: After 12-48 hours, dissolve aluminum potassium sulfate powder with 300 times the weight of water to obtain an aqueous solution of aluminum potassium sulfate powder, and sprinkle the whole pool, wherein the aluminum potassium sulfate used in each cubic meter of water is 0.4- 0.6 grams;

[0024] (3) Water change: After 12-48 hours, pump out 18-25% of the water in the culture pond, inject the same amount of clear water, and then apply biological fertilizer and phosphate fertilizer whose main component is calcium superphosphate to the culture pond to make the water The transparency of t...

Embodiment 2

[0026] Embodiment 2, in the prevention and control method of blue-green algae in the cultivation water body described in embodiment 1, its steps are as follows:

[0027] (1) Sterilization: first reduce the water body in the culture pond to 1 meter, and evenly sprinkle the aqueous mixture solution containing 15 grams of macrolide antibiotics and 500 grams of salt in the water body of the culture pond per mu;

[0028] (2) Detoxification and water improvement: After 24 hours, dissolve the potassium aluminum sulfate powder with 300 times the weight of water to obtain an aqueous solution of potassium aluminum sulfate powder, and sprinkle the whole pool, wherein the potassium aluminum sulfate used in each cubic meter of water is 0.5 grams;

[0029] (3) Water change: After 24 hours, pump out 20% of the water in the culture pond, inject the same amount of clear water, and then apply biological fertilizer and phosphate fertilizer whose main component is superphosphate to the culture pon...

Embodiment 3

[0031] Embodiment 3, in the prevention and control method of cyanobacteria in the cultured water body described in embodiment 1 or 2, when the cyanobacteria in the water body is serious, repeat step (1) once after 24 hours before the operation of step (2), so that the algae completely.

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 [0001] The invention relates to a method for preventing and controlling cyanobacteria, in particular to a method for preventing and controlling cyanobacteria in aquaculture water. Background technique [0002] Blue-green algae is a kind of aquatic plant. The mass reproduction of blue-green algae deteriorates the ventilation and light conditions of the aquaculture water body, and inhibits the growth, reproduction and photosynthesis of beneficial organisms in the water body. Toxins produced by cyanobacteria endanger animal and human health through oral cavity, respiratory system, skin contact and blood penetration. The secondary metabolites of toxins cause aquatic animal eggs to mutate and behave abnormally. Toxin-containing cyanobacteria cells migrate in the water body, co-precipitate with clay or precipitate with their excrement after being preyed on by aquatic organisms, etc., causing toxins to accumulate and stay in the water bottom. , causing a vicious ci...
