Compound preparation for inhibiting growth of moss in aquaculture pond and application thereof

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a compound preparation for inhibiting growth of moss in an aquaculture pond and an application thereof, and the compound preparation is prepared from the following components in parts by mass: 0.1-25 parts of cellulase, 0.1-35 parts of pectinase, 0.1-75 parts of bacillus subtilis powder, 25-125 parts of lanthanum oxide, 1-55 parts of sodium lauryl sulfate, 85-250 parts of citric acid and 400-900 parts of anhydrous sodium sulfate. The characteristics of fast reaching the inside of moss cells, quick action, obvious effect, safety to cultured organisms and ecology and the like can be integrated, the product can be directly put into a culture water body, and has the advantages of small use amount, long storage life, high activity and convenience in use.

Description

Technical field[0001]The present invention belongs to the field of aquaculture technology, and more particularly to composite preparations and applications for the growth of moss in aquaculture pond.Background technique[0002]The floating plants are primary productivity in aquaculture water, which is the basis for maintaining the ecological balance and stability of the water body. Therefore, in the stage of the aquaculture, fertilizer work must be made to ensure the biomass of the floating plants in the water. However, therefore low water temperature, shallow, often floating plants have not been cultivated, but moss is growing.[0003]Moss is aquatic bryophyte plant, green, growing in the water or terrestrial. Moss has a certain harm to aquaculture. (1) Moss can compete with water, other algae, over-consumption of water nutrition, and destroy the normal material metabolism of the pond, so that the cultured water is thin. The consequence of water quality is suppressed by water and grass...

AI Technical Summary

Problems solved by technology

(2) The aquaculture water body where moss grows in large quantities, the water quality is clear and transparent, and the direct sunlight hits the pond, which increases the stress response of crayfish, crabs, and fish. Prolonged stress response can easily lead to a decrease in the immunity of farmed animals and lead to pathological changes

(3) The moss grows and reproduces in large quantities, hanging in the water like a "network", which is easy to entangle crayfish, crabs, and fish. The entangled crayfish, crabs, and fish basically cannot struggle out and can only starve to death. or exhausted

(4) The dead moss blows to the corner of the pool or sinks to rot with the wind. In addition to emitting a foul smell, it will also consume dissolved oxygen in the water during the decomposition process and produce a lot of toxic and harmful substances, resulting in a decrease in dissolved oxygen in the aquaculture water, ammonia nitrogen, Hazardous substances such as nitrite and hydrogen sulfide increase, which deteriorates water quality and causes crayfish, crabs, and fish to die from hypoxia and poisoning, endangering healthy farming

This method is ineffective and will affect the breeding

The second is the method of killing chemical substances. The main chemical herbicides have quick effects, but they have risks and hidden dangers to breeding. Improper handling can lead to the death of farmed animals and aquatic plants

This method is safer, but the action time is long and the effect appears slowly
