Description

Technical Field

[0001] The invention relates to the technical field of biological fish fertilizer, in particular to a deep fermented organic biological fish fertilizer and a preparation method thereof. Background Art

[0002] Traditional fish fertilizers are mainly organic fertilizers and chemical fertilizers, which are mainly used to provide nutrition to plankton such as algae and are used in running water. Their disadvantages are that they have a single function and a long action process. In addition, this type of fertilizer consumes a lot of oxygen during the action process, which affects the water quality.

[0003] The current fish fertilizers are mainly fermented fertilizers and compound fertilizers. For example, the application number "201010195807.7" and the name "Enzyme biological fish fertilizer and its preparation method" disclose a fermented fertilizer. This type of fish fertilizer has many nutritional types and is a double effect of fertilizer and bait. The shortcomings of this type of fish fertilizer are:

[0004] 1. Low degree of fermentation or single fermentation. Biological fish fertilizer can be divided into three categories according to the degree of fermentation: initial fermentation, moderate fermentation and deep fermentation. Initial fermentation can convert the raw materials of fish fertilizer into fiber and high protein, moderate fermentation mainly forms dietary nutrients and nitrogen, phosphorus and potassium elements, and deep fermentation can form the most easily absorbed small peptides and amino acids. Most of the existing fish fertilizers remain in the initial fermentation and moderate fermentation, and their fertilizer absorption capacity is poor;

[0005] 2. Existing fish fertilizers are mainly made of plant raw materials and inorganic substances, lacking animal protein raw materials. The ability of fish fertilizers to combine nitrogen, phosphorus and potassium is poor. Studies have shown that fish fertilizers containing animal protein can increase the content of nitrogen, phosphorus and potassium to 13%, thus having higher nutritional value;

[0006] 3. The effect of adjusting water and decomposing the bottom is not ideal. The existing fish fertilizer has not undergone deep fermentation, and its action process will affect the water quality. At the same time, it has no biological bottom decomposing function. Summary of the invention

[0007] The purpose of the present invention is to solve the above-mentioned technical problems and to provide a deep fermented organic biological fish fertilizer and a preparation method thereof. The fish fertilizer is fermented aerobically and anaerobically multiple times after the raw materials are fermented separately and mixed. The obtained fish fertilizer has high content of small peptides and amino acids, and the fertilizer is easily and thoroughly absorbed. At the same time, chicken animal protein is added, and the nitrogen, phosphorus and potassium content in the fertilizer is high. At the same time, the fish fertilizer has rich nutritional elements and has a good water regulating and bottom improving effect.

[0008] In order to solve the above-mentioned prior art problems, the technical solution of the present invention is:

The fermentation time is 7 to 10 days, and 900 kg of organic feed fermentation material is prepared. The organic feed fermentation material has a wine aroma.

[0049] The step (ii) comprises:

[0050] (1) Select the following organic fertilizer raw materials by weight and add them to mix evenly: 250 kg of rice bran, 10 kg of thermophilic bacteria, and 30 kg of molasses, and store the mixed organic fertilizer raw materials in a fermentation tank;

[0051] (2) Pour 100 kg of animal raw materials and 600 kg of chicken manure into the feeding tank, wherein the animal raw materials include discarded chickens, damaged eggs, and eggshells;

[0052] (3) evenly spreading the organic fertilizer raw material stored in the fermentation tank in step (1) on the organic fertilizer raw material in the feeding tank in step (2);

[0053] (4) The raw materials obtained in step (3) are transferred to an intelligent fermentation tank by a forklift for natural fermentation. The temperature of the intelligent fermentation tank is 60-65 degrees, and the fermentation time is 15 days. 850 kg of organic fertilizer fermentation material is prepared. The moisture content of the organic fertilizer fermentation material in the intelligent fermentation tank is 35%.

[0054] The step (iii) comprises:

[0055] (1) 600 kg of the organic feed fermentation material prepared in step (1) and 400 kg of the organic fertilizer fermentation material prepared in step (2) are mixed and stirred evenly, and then conveyed to a fermentation aeration tank by a conveyor belt for accumulation and anaerobic fermentation, and the anaerobic fermentation time is 7 to 10 days;

[0056] (2) transferring the mixed raw material after anaerobic fermentation in step (1) into a turning tank, and then performing aerobic fermentation, the aerobic fermentation time is 15 days, and the fermentation temperature is 50 to 60 degrees;

[0057] (3) transferring the mixed raw materials after aerobic fermentation in step (2) into a turning tank for turning treatment, turning once every 3 to 5 days, and then piling up after turning, and the turning time is 15 days;

[0058] (4) After the mixing and turning in step (3), the mixed raw materials are transferred to a forklift mixing and turning room, piled to a height of 2.5 meters, and continued to ferment and age. The mixed raw materials are turned over every 7 days for a fermentation and aging period of 2 months, and finally 900 kg of deep fermented organic biological fish fertilizer is produced.

[0059] The entire fermentation time of the deep fermented organic biological fish fertilizer is more than 4 months. The organic biological fish fertilizer fermented in this way can achieve the dual effects of fertilizer and bait, adjust water, improve bottom, is non-toxic and harmless, has no side effects, and scientifically fertilizes water, making aquaculture highly economical.

[0060] The feed of this deep fermented organic biological fish fertilizer accounts for more than 50%, which can be directly provided to fish to meet the nutritional supply of fish. It has a wide range of applications. However, for some ponds with poor water quality, conventional fertilizers cannot achieve fertilization to meet the nutritional supply of fish.

[0061] This deep fermented organic biological fish fertilizer uses wheat bran and rice bran combined with fungi, contains a large amount of plant fiber and minerals, can decompose and replace the materials at the bottom of the pond, play a role in loosening the bottom of the pond and biologically improving the bottom;

[0062] The temperature of the deep fermentation organic biological fish fertilizer reaches 65 degrees during the fermentation process, which can sterilize the fertilizer very well and completely disinfect wild fungi and insect eggs. At the same time, the fermentation bacteria are treated with coating technology, and can perform the fermentation function in a protected state.

[0063] The thermophilic bacteria are Bacillus subtilis, lactic acid bacteria, and Saccharomyces cerevisiae;

[0064] The high-temperature bacteria are live bacteria treated with coating technology, are resistant to high temperatures, and are highly efficient biological fermentation agents specifically used for farm manure treatment. They are a compound of three strains of Bacillus subtilis, Saccharomyces cerevisiae, and lactic acid bacteria that can strongly decompose livestock and poultry manure. The strains do not antagonize each other and have a synergistic effect. They have extremely strong organic matter decomposition capabilities, can quickly decompose manure, remove manure odor, eliminate pests and diseases, and enrich nutrients.

[0065] In the fermentation process of step (iii), first, the mesophilic microorganism Saccharomyces cerevisiae utilizes the soluble substances in the feces to proliferate continuously, promoting the temperature to rise continuously. The soluble substances are sugars and starches. When the temperature of the pile rises to above 45°C, it enters the high-temperature stage. At this time, the growth of Saccharomyces cerevisiae is inhibited or even dies, and the thermophilic microorganism Bacillus subtilis gradually replaces the activity of the mesophilic microorganism. After the high-temperature stage, the pile begins to undergo a humus formation process corresponding to the decomposition of organic matter, and the compost material gradually enters a stable state.

[0066] Bacillus subtilis was used for high temperature resistance test. The effects of different treatment times on the survival of Bacillus subtilis are shown in the following table:

[0067]

[0068]

[0069] It can be seen from the above table that: after Bacillus subtilis was treated at 100°C for 15 minutes and 30 minutes respectively, the loss rate of live bacteria was only 2.1% and 4.2%; after being treated at 100°C for 45 minutes and 60 minutes respectively, the loss rate of live bacteria was 11.5% and 15.7% respectively. This data shows that Bacillus subtilis has sufficient high temperature resistance and is suitable as a component of manure fermentation agent.

[0071] The difference between Example 2 and Example 1 is as follows: Step (III) includes:

[0072] (1) 540 kg of the organic feed fermentation material prepared in step (1) and 360 kg of the organic fertilizer fermentation material prepared in step (2) were selected, mixed and stirred evenly, and added into a fermentation tank for anaerobic fermentation for 7 to 10 days;

[0073] (2) transferring the mixed raw material after anaerobic fermentation in step (1) into a turning tank, and then performing aerobic fermentation, the aerobic fermentation time is 15 days, and the fermentation temperature is 50 to 60 degrees;

[0074] (3) transferring the mixed raw materials after aerobic fermentation in step (2) into a turning tank for turning treatment, turning once every 3 to 5 days, and then piling up after turning, and the turning time is 15 days;

The mixed raw materials are turned over every 7 days for a fermentation and aging period of 2 months, and finally 800 kg of deep fermented organic biological fish fertilizer is produced.
