Embodiment 1

[0025] A preparation method of seaweed industrial waste residue organic fertilizer, comprising the steps of:

[0026] (1), pre-fermentation treatment

[0027] According to the weight ratio, 50% of the dry seaweed waste residue, 49% of the activated sludge from the domestic sewage plant, mixed with potassium dihydrogen phosphate accounting for 1‰ of the dry weight of the seaweed waste residue, and 0.5‰ of the corrosion accelerator, is it added here? , 10‰ shell powder, the water content is adjusted to account for 50%-70% of the dry weight of seaweed waste residue, and mixed with a tumbler;

[0028] (2), micro-aerobic fermentation

[0029] Heap temperature rises to 40°C, inoculates with rot-promoting agent, then turns the heap once every two days, and measures the water content every 3 days to ensure that the water content of the heap is 50% during the high temperature period, and the fermentation time is 18 days;

[0030] The active ingredient of the above decay accelerator i...

Embodiment 2

[0034] (1), pre-fermentation treatment

[0035] According to the weight ratio, 90% of the dry seaweed residue and 9% of wheat bran are mixed with potassium dihydrogen phosphate accounting for 10‰ of the dry weight of the seaweed residue, and 1‰ of shell powder, and the water content is adjusted to account for 60% of the dry weight of the seaweed residue. Tumbling machine to mix;

[0036] (2), micro-aerobic fermentation

[0037] The pile temperature rises to 45°C, inoculates the decay accelerator, turns the pile every three days, and measures the water content every three days to ensure that the water content of the pile is 50% during the high temperature period. The fermentation time is 26 days;

[0038] The active ingredient of the above-mentioned decay accelerator is a mixture of bacteria and yeast, and the inoculation amount is 7‰;

[0039] (3), drying and crushing

[0040] After the fermentation is completed, the heap temperature drops to room temperature, and the deco...

Embodiment 3

[0042] 40% of the seaweed waste residue organic fertilizer obtained in Example 2 is compounded with 15% potassium sulfate, 20% ammonium sulfate, 5% potassium chloride, and 20% monoammonium phosphate by weight percentage to make an organic- Inorganic fertilizer, used in green food planting and production.

Abstract

The invention discloses a preparation method and an application method of a seaweed industrial solid waste organic fertilizer. The preparation method comprises the steps of: mixing seaweed solid waste with additives, adding water, and adding a decomposition accelerator to perform micro-anaerobic fermentation, drying and crushing after the fermentation procedure to obtain the seaweed industrial solid waste organic fertilizer. The application method of the seaweed industrial solid waste organic fertilizer comprises the step of directly applying or adding other inorganic fertilizers to prepare an organic-inorganic compound fertilizer. The preparation method of the seaweed industrial solid waste organic fertilizer, disclosed by the invention, has the advantages of short fermentation period, simple fermentation technique and high compost nutrient storage rate.

Description

technical field [0001] The invention mainly relates to a seaweed organic fertilizer, in particular to a preparation method and an application method of an organic fertilizer using seaweed industrial waste residue as a raw material. Background technique [0002] Our country has a vast sea area and is rich in seaweed resources. At present, scholars at home and abroad mainly study some active ingredients in seaweed, and there are not many studies on the comprehensive utilization of seaweed. In industry, apart from the extraction of sodium alginate, iodine, mannitol and alginate, the comprehensive utilization of seaweed rarely involves the comprehensive utilization and treatment of waste after extraction. The waste residue after seaweed extraction contains a large amount of hemicellulose, cellulose, lignin and other substances that are difficult to decompose and utilize. At present, most seaweed waste residues are treated as industrial waste because they cannot be used in time....
