A kind of substrate improving agent for breeding and preparation method thereof

Abstract

The invention discloses a culture substrate modifier and a preparation method thereof. The modifier comprises, in weight percentage, 15%-35% of cut tobaccos, 5%-20% of bran, 20%-35% of turf, 25%-45% of dolomite powder, 1%-5% of strains and 1%-8% of molasses, wherein the strains comprise bacillus subtilis, Lactobacillus acidophilus and candida utilis. The cut tobaccos, the bran and composite strains of the bacillus subtilis, the Lactobacillus acidophilus and the candida utilis are combined by process flow to modify and regulate a substrate and water quality, dissolved oxygen at the bottom of a pond is increased, breeding of aerobic probiotics is promoted, and breeding of harmful toxic algae is inhibited. The modifier can purify the substrate, organic pollutants such as dead algae, feces and residual feeds at the bottom of the pond are decomposed, the breeding environment of pathogenic organisms, namely, parasites of the pond is changed, harmful substances such as ammonia nitrogen, nitrite, sulfide and algal toxin at the bottom of the pond can be decomposed, and diseases are reduced in aquaculture.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a substrate improving agent for breeding and a preparation method thereof. Background technique [0002] With the improvement of intensive farming and the increase of breeding density, the ecological structure of aquaculture itself and the defects of traditional farming methods have caused many outstanding problems in the aquaculture industry. The abuse of fish medicines has led to ecological fragility and the decline in the safety of aquatic products. There are a series of problems such as the decline of seedling quality, drug abuse, and unscientific feed formula. During the breeding process, a large amount of residual bait and waste are deposited on the bottom of the pond. Long-term accumulation and decomposition lead to an increase in the concentration of nutrients and organic matter in the sediment and water. , the transparency decreases, the dissolved oxygen in the water b...

Problems solved by technology

[0002] With the improvement of intensive farming and the increase of breeding density, the ecological structure of aquaculture itself and the defects of traditional farming methods have caused many outstanding problems in the aquaculture industry. The abuse of fish medicines has led to ecological fragility and the decline in the safety of aquatic products. There are a series of problems such as the decline of seedling quality, drug abuse, and unscientific feed formula. During the breeding process, a large amount of residual bait and waste are deposited on the bottom of the pond. Long-term accumulation and decomposition lead to an increase in the concentration of nutrients and organic matter in the sediment and water. , the transparency decreases, the dissolved oxygen in the water body decreases, the concentration of ammonia nitrogen and nitrite increases, and harmful microorganisms reproduce in large numbers. The residue and enrichment of antibiotics in the body will bring great hidden dangers to aquaculture production and the quality and safety of aquatic products

And the bottom of the pond is in anoxic state, the survival rate of bacteria with strong decomposition ability is not high, and it is very likely to accelerate the anoxic state at the bottom of the pond
