Problems solved by technology

The increase of nitrogen concentration in aquaculture water, on the one hand, can cause eutrophication of the water body, leading to the outbreak of blue-green algae, on the other hand, it can affect the growth of aquatic organisms, reduce their resistance to adverse environments and diseases, and become the main cause of disease. Affect aquaculture production; Nitrogen pollution has become the main stress factor restricting the aquaculture environment. The conventional mode to adjust water quality is usually water thinning and fertilization, and changing water when the water is old, wasting a lot of water resources, which is contradictory to the current situation of scarcity of fresh water resources in my country , or use probiotics for reconciliation. The existing probiotics are generally water or powder. Need to be activated before, the effect is unstable, etc.

Abstract

The invention relates to a microecological preparation for freshwater aquaculture, which is characterized in that the microecological preparation is paste with the water content of 15-25% and comprises the following components in parts by weight: 23-32 parts of bacillus, 4-7 parts of myxobacteria, 4-6 parts of lactic acid bacteria, 23-32 parts of saccharomycetes, 12-18 parts of nitrifying bacteria, 1-5 parts of photosynthetic bacteria and 2-3 parts of culture medium. Bacillus, myxobacteria, lactic acid bacteria, saccharomycetes, nitrifying bacteria and photosynthetic bacteria are fermented in a culture medium with the pH value of 6.0-7.5 at the temperature of 25-30 DEG C under illumination, the content of viable bacteria is high, the shelf life is as long as 24 months or longer, the microecological preparation can effectively remove inorganic nitrogen and organic nitrogen in aquaculture wastewater, the denitrification effect is remarkable, and ecological balance of the bottom of water is kept. The microecological preparation is stable in quality, safe, reliable, green, environment-friendly and pollution-free, and has a remarkable effect of promoting healthy and stable development of the aquaculture industry.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a microecological preparation for freshwater aquaculture. Background technique [0002] In recent years, the scale of freshwater aquaculture has gradually expanded, and the production of freshwater has been greatly improved. However, under high-density aquaculture conditions, water quality problems often affect the healthy growth of aquatic products, and diseases occur from time to time, which limits the sustainable and healthy development of the freshwater industry, and in the process of freshwater aquaculture, inorganic nitrogen and organic nitrogen often appear in ponds. Nitrogen, nitrogen is an important water quality indicator that has attracted much attention in aquaculture. Nitrogen in aquaculture water consists of non-ionic ammonia (NH 3-N), which mainly comes from the conversion and decomposition of nitrogen-containing substances, including inorganic and organic nit...
