Description
Technical Field
The invention relates to the technical field of aquaculture, in particular to a composite ecological treating agent for treating blue-green algae and a preparation method and application thereof.
Background
River crabs and crayfishes are main characteristic aquatic products in Jiangsu province, and in 2019, the annual output of the river crabs and the crayfishes respectively reaches 36.48 ten thousand tons and 20.44 ten thousand tons. In the process of culturing river crabs and crayfishes, good water quality is a necessary condition for the healthy growth of the river crabs and the crayfishes. In recent years, due to the reasons that weather or waterweeds are poorly managed, a large amount of icefish is fed, and the like, blue algae frequently explode in the river crab and crayfish culture pond in 6-9 months at a high temperature. Blue algae can be quickly propagated and can be distributed in the whole pond within 2-3 days at the fastest speed, and when dissolved oxygen in water is greatly consumed by the blue algae or weather mutation occurs at night, a large amount of algae can die due to insufficient oxygen. When the blue algae die, a large amount of toxic and harmful substances such as hydroxylamine, hydrogen sulfide and the like are generated, and the substances are accumulated in water to cause fish poisoning and death, so that the survival rate of shrimps and crabs is reduced, the culture yield is reduced, and great economic loss is caused to farmers.
Currently, methods for killing blue algae in the existing records include drainage methods, mechanical collection and removal methods and drug killing methods. The drainage method is characterized in that by means of the characteristic that blue-green algae like strong light, 30-40 cm of surface water body is drained in the middle of a fine day, and the quantity of the blue-green algae in the pool water can be effectively reduced. The drainage method has the advantages that blue algae in the pond can be quickly drained without influencing the survival of river crabs and crayfish; the disadvantage is that the blue algae can not be killed thoroughly, and the blue algae is easy to roll up the soil to cover the whole pond in a high-temperature sunny day. The mechanical collecting and removing method is to collect the blue algae in the surface water body by using mechanical equipment and remove the blue algae from the pond. The mechanical collection and removal method consumes a lot of manpower and material resources, and is rarely used at present. The medicine killing method is to kill blue algae with halogen bleaching powder, strong chlorine, chlorine dioxide, bromochlorohydantoin, heavy metal salt copper sulfate, strong oxidant potassium permanganate, etc. The method has the advantages of time and labor saving, and thorough blue algae killing, and has the defects that the medicaments stimulate the growth of river crabs and crayfishes to influence the growth of the river crabs and the crayfishes, and the river crabs and the crayfishes die due to improper operation even oxygen deficiency and other factors.

In examples 1 to 3 and comparative examples 1 to 7, the growth of shrimps and crabs in the pond after 7 days of application of the composite ecological treating agent is shown in Table 8:
TABLE 11
As can be seen from tables 1 to 11, in examples 1 to 3, after the composite ecological treatment agent is applied for 7 days, blue algae are effectively controlled, the culture of shrimps and crabs in the pond is not affected, and the shrimps and crabs grow well; in comparative examples 1-2, after 7 days of application of the composite ecological treatment agent containing no splash-water detoxified vitamin C or granular oxygen, the concentration of blue algae was reduced but not effectively controlled, the stress response of river crabs was obvious, and the ingestion was reduced; in the comparative example 3, after the composite ecological treating agent with the adjusted weight ratio of the components is applied, the pond has slight oxygen deficiency, the cost of preventing and controlling blue algae is increased, and river crabs have slight emergency reaction; in comparative examples 4-5, the blue algae concentration was reduced but not effectively controlled before the sprinkling time of the composite ecological treatment agent was adjusted to 6:00 and 6:30 in the morning, the pond had a slight anaerobic phenomenon, and river crabs had a slight emergency reaction, because the sprinkling time of the composite ecological treatment agent was too early, the water in the pond was in a hypoxic period, and the blue algae had floated to the surface of the water after the sprinkling time was too late, which resulted in this situation; in comparative examples 6 to 7, the blue algae were controlled by adjusting the positions of spraying the composite ecological treating agent to 1/4 area and 1/2 area in the downwind direction of the pond, but the blue algae treatment effect was reduced as compared with example 1 because the area of application of the composite ecological treating agent was too large or too small.
The bacillus compositus, the zeolite powder, the water-splashing detoxifying vitamin C and the granular oxygen are all purchased from the market.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
