Problems solved by technology

With the development of aquaculture, high-density aquaculture requires a large amount of feed, and bait residues and aquatic animal excrement pollute the aquaculture water, resulting in NH 3 、H 2 Harmful substances such as S and organic matter increase, chemical oxygen demand (COD) and biological oxygen consumption (BOD) increase, which seriously affects the growth of aquatic animals
Most of the existing water body improvers are mixed with inorganic fertilizers such as chicken manure and chemical fertilizers such as ammonium bicarbonate. Not only the effect is not good, but also it will cause secondary pollution of the water body. Long-term use will affect the health of my country's aquaculture industry. develop

Embodiment 1

[0022] A compound water quality improver for aquaculture, which consists of the following components by weight percentage: 45% amino acid, 10% biological small peptide, 20% bacillus, 10% potassium dihydrogen phosphate, 5% biological enzyme and glucose 10%.

[0023] preparation:

[0024] 1) Activation of Bacillus strains: Inoculate Bacillus strains with a bacterial count of 20 billion / g in a medium made of brown sugar, purified water and organic acids, adjust the pH to 7.0, and the inoculation amount accounts for 0.5% of the medium. Temperature is 40 DEG C, ferment for 12 days, when the number of bacteria reaches 5 billion / g, get bacillus for later use.

[0025] 2) Weigh each raw material according to the formula in Example 1, add it into a stainless steel reaction kettle, mix it, and stir it at 50°C for 30 minutes to obtain a tan paste, which is the composite water quality used in aquaculture in Example 1 of the present invention Improver.

[0026] The water quality improve...

Embodiment 2

[0028] A compound water quality improver for aquaculture, consisting of the following components by weight percentage: 40% amino acid, 10% biological small peptide, 15% bacillus, 10% potassium dihydrogen phosphate, 5% biological enzyme and glucose 20%.

[0029] Preparation: with embodiment 1.

[0030] Embodiment 2 of the present invention water body improving agent, dosage is 2000g / mu, after proportional dilution, whole pond is evenly splashed, has good effect to fast fertilizing water, increasing oxygen, deodorizing, reducing ammonia nitrogen.

Abstract

The invention provides a compound water quality improver for aquaculture and a preparation method thereof. The compound water quality improver is prepared from the following components in percentage by weight: 40-60% of amino acids, 10-15% of small biological peptides, 15-25% of bacillus, 10-15% of monopotassium phosphate, 5-10% of a bio-enzyme and 10-20% of glucose. By using a biological preparation as a main raw material, the improver is free of components such as chicken manure, carbon and ammonia which easily damage the water quality. The components are interacted, so that not only can water be quickly enriched, but also algae phase can be balanced. The dissolved oxygen is improved and harmful substances such as NH3 and nitrite in water are reduced, so that no secondary pollution is caused on aquatic water. The improver has a food calling effect on bred animals, particularly remarkable effect on food refusal effect caused by using vermifuge for the bred animals. The improver provided by the invention is simple in preparation method and easily dissolved in water and can be put in the breeding process, so that the improver is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of aquaculture and relates to a water quality improver, in particular to a composite water quality improver capable of fattening aquatic animal breeding water and a preparation method thereof. Background technique [0002] China is the world's largest aquaculture country, and aquaculture plays an important role in agricultural production. At the same time, China is also one of the countries with the most serious pollution of aquaculture water. Since ancient times, there has been a saying in China that "fish farming first raises water". The water quality and bottom quality of aquaculture water determine the ecological environment quality of aquaculture water. With the development of aquaculture, high-density aquaculture requires a large amount of feed, and bait residues and aquatic animal excrement pollute the aquaculture water, resulting in NH 3 、H 2 Harmful substances such as S and organic matter increase...
