Ecological restoration agent for aquaculture water area and preparation method thereof

Abstract

The invention discloses an ecological restoration agent for an aquaculture water area, and relates to the technical field of pesticide compounding. The restoration agent consists of the following components in parts by weight: 100 to 200 parts of compound bacteria, 100to 200 parts of sodium humate, 660 to 800 parts of amino acid fertilizer water powder and 0.5 to 1.5 parts of compound sodium nitrophenolate. According to the ecological restoration agent disclosed by the invention, after the microorganism preparation is added into a water body, effects of oxidization, ammoniation, denitrification, phosphor-resolving, vulcanization, nitrogen fixation and the like are brought into play; organic substances such as excrements of aquaculture animals, remaining feed, animal and plant remians and the like are quickly decomposed, so that concentration of ammonia nitrogen and nitrite in the water body can be effectively reduced; and decomposed salts of the organic substances provide nutrition for growth and reproduction of unicellular alga, so that photosynthesis of the unicellular alga is guaranteed, dissolved oxygen in the water body is improved, and therefore, a good ecological water environment is built and kept.

Description

technical field [0001] The invention relates to an aquaculture water ecological restoration agent for stabilizing the water quality of aquaculture ponds and a preparation method thereof, belonging to the technical field of aquaculture. Background technique [0002] Summer is the peak growth season for fish, and it is also the season when various diseases are prone to occur. The ammonia nitrogen in the water body increases, and the water quality changes frequently, such as heavy metal ions, disinfectants, and pesticide residues, which can easily cause stress reactions in aquatic animals, resulting in death. Moreover, the accumulation of residues of these drugs in aquatic animals will bring new hidden dangers to the further prevention and treatment of aquatic animal diseases and human food safety and health. [0003] After many years of cultivating fish and shrimp in ponds, a large amount of silt and humus will accumulate at the bottom of the pond, making a large number of pa...

Problems solved by technology

Different algae’s demand for various nutrients in the water body: When the organic matter content in the water body is too large, the dinoflagellate algae in the pond will multiply, which will easily lead to the formation of a dominant species of algae, such as euglena. Although this algae has a strong oxygen production capacity, However, the large oxygen consumption at night leads to large changes in the dissolved oxygen in the aquaculture water, which in turn causes the aquaculture objects to lack oxygen in the morning and float their heads.

The continuous reduction of beneficial algae and the increase of harmful algae, the continuous increase of ammonia nitrogen and nitrite in the water will cause a large number of harmful algae to multiply, resulting in the deterioration of water quality

[0005] In high-density aquaculture water, in order to maintain a good algae phase balance, artificially adding beneficial algae species is a method, but the quantity is limited and the cost is too high

Most of the common microbial water-adjusting agents on the market use microorganisms to adjust, ignoring the balance of N:P:C required by the algal phase. The disadvantages or shortcomings are: when using pure microbial water quality adjustment products, often In the first few days, due to the germination process of microorganisms, especially bacillus, and the recovery and activation process of the strains, a large amount of dissolved oxygen in the water body needs to be consumed in a short time, resulting in short-term hypoxia in the water body. It may cause hypoxic death to fish living in the water body. Therefore, farmers often need to choose to use this type of product on sunny days, when algae photosynthesis is strong and windy, or turn on the aerator while using it. To cooperate, otherwise it may cause the death of fish due to hypoxia;

[0007] Although there are many products and methods used for water treatment, and they also have certain effects, they are generally single-targeted and only start from a certain biological factor in the water body.

However, ignoring the balance between the various organisms in the water body has the effect of "curing the head for headaches and treating the feet for foot pains", which cannot fundamentally solve the problem.

[0008] Moreover, the frequent use of traditional disinfectants in the aquaculture process leads to the inhibition of all harmful and beneficial bacteria. After use, it will lead to the destruction of the pond bacterial phase, resulting in NH -3 —N, NO -2 -N rise

After the use of traditional disinfectants, the balance of algae will be broken, and if the amount is too large, it will cause water transfer
