Embodiment 1

[0029]Example 1: Insert the thermostable facultative anaerobic bacteria Bacillus methylotrophicus HL-4 preserved on the slant into the LB liquid medium cooled after sterilization, cultivate it at 55°C and 150 r / min for 12 hours, and prepare Bacillus methylotrophicus HL-4 seed liquid for later use ; Mix bran and water in a mass ratio of 1:1, and mix well to prepare bran medium. Bran culture is based on sterilization at 121°C for 30 minutes before use; the prepared Bacillusmethylotrophicus HL-4 seed solution is inserted into After sterilization, put the bran medium in the cooled bran medium and mix it evenly, then divide the bran medium into which the strains are inserted into the sterilized fermentation shallow pan, the thickness of the filling is 4cm, and the surface of the fermentation medium in the shallow pan is covered Sterilized wet gauze, and then put the tray on the shelf in the sterilized solid fermentation room to ferment, control the ambient temperature at 55°C, and f...

Abstract

The invention discloses a method of utilizing aquatic product viscera and oyster shells to prepare organic fertilizer.The method mainly includes following steps: culturing high-temperature-resistant facultative anaerobe methyl nutritional bacillus (Bacillus methylotrophicus) HL-4 to obtain a microbial agent for standby use; well mixing the microbial agent with enzyme to obtain a fermentation agent for standby use; well mixing the aquatic product viscera, oyster shell powder, animal excrement and excipients to obtain an organic fertilizer fermentation medium; adding the fermentation agent into the organic fertilizer fermentation medium for heap building fermentation in a natural standing manner for 7-40 days; drying, smashing and packaging a product after fermentation to obtain the organic fertilizer.The aquatic product viscera and the oyster shells are utilized in a high-value manner, and heap turning is not needed in the whole preparation process of the organic fertilizer, so that equipment investment and labor cost are saved and the method has good application prospect.

Description

technical field [0001] The invention relates to a method for preparing organic fertilizer by using the internal organs of aquatic products and oyster shells, and belongs to the technical field of processing and utilization of aquatic products. Background technique [0002] Bio-organic fertilizer is an organic fertilizer containing a certain amount of functional microorganisms, which is made from livestock and poultry manure, crop straw, agricultural by-products and organic waste from food processing, and is decomposed and fermented with a multifunctional fermentation strain agent. Organic fertilizers are rich in organic nutrients such as organic matter, amino acids, and proteins, as well as inorganic nutrients such as nitrogen, phosphorus, and potassium. The production of organic fertilizers can not only turn solid wastes into treasures, but also contribute to environmental protection and promote the sustainable development of agriculture in our country.
