Embodiment 1

[0040] The freshwater aquaculture fertilizer and aquatic product of the present invention comprises the following raw materials in mass percentage: 92% of amino acid fermentation liquid, 2% of magnesium oxide, 2% of lime, 2% of ferrous sulfate, and 2% of borax.

[0041] The amino acid fermentation broth is prepared by the following steps in sequence:

[0042] ① Wash the rice with water, soak it, and then grind it with water at a mass ratio of 1:1 to obtain rice milk;

[0043] ②Saccharify the rice milk at 100°C for 50 minutes, and test it with iodine solution at intervals of 25 minutes until the color is dark brown red, which means the saccharification is complete, then neutralize with acid and alkali to adjust the pH to 7.0, and finally obtain the sugar solution by filtration;

[0044] ③ After the sugar liquid is sterilized, ferment at 0.08Mpa pressure and 33.5°C for 32h to obtain amino acid fermentation liquid. The freshwater aquaculture fertilizer and aquatic products are i...

Embodiment 2

[0051] The freshwater aquaculture fertilizer and aquatic product of the present invention comprises the following raw materials in mass percentage: 90% of amino acid fermentation liquid, 2.5% of magnesium oxide, 2.5% of lime, 2.5% of ferrous sulfate, and 2.5% of borax.

[0052] The amino acid fermentation broth is prepared by the following steps in sequence:

[0053] ① Wash the rice with water and soak it, then grind it with water at a mass ratio of 1:0.8 to obtain rice milk;

[0054] ②Saccharify the rice milk at 105°C for 60 minutes, and test it with iodine solution at an interval of 30 minutes until the color is dark brown red, which means the saccharification is complete, then neutralize with acid and alkali to adjust the pH to 7.0, and finally obtain the sugar solution by filtration;

[0055] ③ After the sugar liquid is sterilized, it is fermented at 0.05Mpa pressure and 34°C for 30h to obtain amino acid fermentation liquid. The freshwater aquaculture fertilizer and aquat...

Embodiment 3

[0063] The freshwater aquaculture fertilizer and aquatic product of the present invention comprises the following raw materials in mass percentage: 94% of amino acid fermentation liquid, 1.5% of magnesium oxide, 1.5% of lime, 1.5% of ferrous sulfate, and 1.5% of borax.

[0064] The amino acid fermentation broth is prepared by the following steps in sequence:

[0065] ① Wash the rice with water and soak it, then grind it with water at a mass ratio of 1:1.2 to obtain rice milk;

[0066] ② Saccharify the rice milk at 96°C for 40 minutes, and test it with iodine solution at specific intervals, until the color is dark brown red, which means the saccharification is complete, then neutralize with acid and alkali to adjust the pH to 7.0, and finally obtain the sugar solution by filtration;

[0067] ③ After the sugar liquid is sterilized, it is fermented at 0.1Mpa pressure and 33°C for 34 hours to obtain amino acid fermentation liquid. The freshwater aquaculture fertilizer and aquatic...

Abstract

The invention relates to a freshwater aquaculture water fertilizing product and a preparation method thereof. The freshwater aquaculture water fertilizing product comprises the following raw materialsin percentage by mass: 90-94% of an amino acid fermentation broth, 1.5-2.5% of magnesium oxide, 1.5-2.5% of lime, 1.5-2.5% of ferrous sulfate and 1.5-2.5% of borax. The freshwater aquaculture water fertilizing product overcomes the defect that water body pollution, disease propagation and too high content of heavy metals in water bodies are caused as urea, ammonium bicarbonate and superphosphateare mostly used or chicken and duck excrement is directly used in a conventional freshwater aquaculture water fertilizing product, and has the advantages of low cost, cleanliness and sanitation, no water body pollution and good fertilizer water effects.

Description

technical field [0001] The invention relates to a freshwater aquaculture fertilizer and aquatic product and a preparation method thereof, which are applied in the field of freshwater aquaculture. Background technique [0002] The traditional fertilizer and aquatic products raised in fresh water mostly use urea, ammonium bicarbonate, superphosphate or directly use chicken and duck manure. The use of urea, ammonium bicarbonate, and superphosphate into the water body will easily lead to eutrophication of the water body, causing a sharp decrease in the dissolved oxygen content of the water body, deteriorating the water quality, and even affecting the survival of freshwater aquaculture products. However, the use of chicken and duck manure can easily lead to the breeding of diseases, and the heavy metals in the water body are too high, which is not conducive to the growth and quality of freshwater aquaculture products. Moreover, the cost of the fertilizer and water products is hi...
