Embodiment 1

[0025] The preparation method of the multifunctional aquaculture water body improver is as follows:

[0026] Shredded tobacco, tea seed cake, vinegar grains, fish meal, bean cake, and bran are respectively pulverized, passed through a 100-mesh sieve, and based on the weight ratio of dry matter: 10% of shredded tobacco, 15% of tea seed cake, 18% of vinegar grains, 32% of fish meal, 20% of bean cake, and 5% of bran are mixed evenly to make 10 kg of mixture. Add 40mL of EM active calcium solution. The method is to dilute the EM active calcium solution with an appropriate amount of chlorine-free water, spray evenly on the mixture, and adjust the water content of the mixture to about 40% with chlorine-free water. After 6 days of anaerobic fermentation, 200 grams of attapulgite clay passed through a 200-mesh sieve was added, mixed evenly, granulated by a granulator, with a particle size of 6.0mm, dried at 50°C, and a water content of about 10%.

Embodiment 2

[0028] The preparation method of the multifunctional aquaculture water body improver is as follows:

[0029] Shredded tobacco, tea seed cake, vinegar grains, fish meal, bean cake, and bran are respectively pulverized, passed through an 80-mesh sieve, and based on the weight ratio of dry matter: 15% of shredded tobacco, 10% of tea seed cake, 20% of vinegar grains, 30% of fish meal, 20% of bean cake, and 5% of bran are mixed evenly to make 10 kg of mixture. Add 50mL of EM active calcium solution. The method is to dilute the EM active calcium solution with an appropriate amount of chlorine-free water, spray evenly on the mixture, and adjust the water content of the mixture to about 40% with chlorine-free water. After 7 days of anaerobic fermentation, 200 grams of attapulgite clay passed through a 200-mesh sieve was added, mixed evenly, granulated by a granulator, with a particle size of 5.0 mm, dried at 50 ° C, and a water content of about 12%.

Embodiment 3

[0031] The preparation method of the multifunctional aquaculture water body improver is as follows:

[0032] Shredded tobacco, tea seed cake, vinegar grains, fish meal, bean cake, and bran are respectively pulverized, passed through a 100-mesh sieve, and based on the weight ratio of dry matter: 18% of shredded tobacco, 12% of tea seed cake, 15% of vinegar grains, 30% of fish meal, 20% of bean cake, and 5% of bran are mixed evenly to make 10 kg of mixture. Add 30mL of EM active calcium solution. The method is to dilute the EM active calcium solution with an appropriate amount of chlorine-free water, spray it evenly on the mixture, and adjust the water content of the mixture to about 40% with chlorine-free water. After 5 days of anaerobic fermentation, add 200 grams of attapulgite clay through a 200-mesh sieve, mix evenly, granulate with a granulator, the particle size is 5.0mm, and dry at 60°C, with a water content of about 12%.

Abstract

The present invention discloses a preparation method of multifunctional aquaculture water body improver. By combining micro-ecological theories, disease preventing and bacteria killing cut tobaccos, tea seed cakes, vinegar residues, etc. are subjected to co-fermentation with powerful EM active calcium liquid, and the improver is prepared by mixing and granulating using a special technology. The preparation method includes the following specific steps: (1) material blending; (2) anaerobically fermenting; and (3) granulating. The prepared aquaculture water body improver has effects of improving nutrition, killing insects, preventing bacteria, improving water, promoting dredging, etc.

Description

technical field [0001] The invention belongs to the category of aquaculture, and specifically relates to an aquaculture water body improver with the functions of nutrition, water regulation, disease prevention and dredging and a preparation method thereof. Background technique [0002] Aquaculture products such as crabs and prawns are rich in nutrition and unique in flavor, and are favored by the market. The vast rural areas use paddy fields, ponds, lakes, and rivers for farming, and the breeding area and production scale continue to expand. However, high-density farming, excessive feed, and drug abuse have brought about deterioration of the aquaculture environment, frequent occurrence of diseases and insect pests, serious water pollution and aquatic products. Yield and quality decline and other issues. How to efficiently and quickly adjust the aquaculture water body to meet the nutritional and water quality requirements of aquaculture and reduce the occurrence of diseases ...
