Problems solved by technology

After extracting carrageenan polysaccharides, the main components left in the algae dregs are high-molecular insoluble substances such as seaweed fiber, protein, and insoluble seaweed polysaccharides. These macromolecular substances are difficult to be absorbed and utilized by plants without treatment.

Embodiment 1

[0014] The carrageenan algae residue organic fertilizer is composed of 0.5% monoammonium phosphate, 20% auxiliary materials, 0.5% microbial fermentation agent and the balance is carrageenan algae residue.

[0015] Carrageenan algae residue organic fertilizer preparation method:

[0016] By weight percentage, take the carrageenan algae residue with a moisture content of 82%, after natural air-drying, make its moisture content reach 60%, add 0.5% monoammonium phosphate, adjust the pH of the material to 7.0, then add 20% bran and 0.5% microbial starter (the microbial starter can be selected from products produced by Huaian Dahua Biological Products Factory), and all auxiliary materials are fully mixed with compost materials. When the temperature of the fermentation pile reaches 65°C, turn the pile in time to increase air permeability and add a certain amount of water, and then turn the pile once on the 3rd, 5th, and 7th days after inoculation, and maintain the material temperatur...

Embodiment 2

[0019] The carrageenan algal residue organic fertilizer is composed of 0.2% monoammonium phosphate, 10% auxiliary materials, 0.25% microbial fermentation agent and the balance is carrageenan algal residue.

[0020] By weight percentage, take the carrageenan algae residue with a moisture content of 82%, press and dehydrate it to make its moisture content reach 65%, add 0.2% monoammonium phosphate, adjust the pH of the material to 7.4, and then add 10% bran and 0.25% microbial starter, all auxiliary materials are fully mixed with compost materials. When the temperature of the fermentation pile reaches above 62°C, turn the pile in time to increase air permeability and add a certain amount of water, and then turn the pile once respectively on the 3rd, 5th, 7th, and 9th days after inoculation, and maintain the temperature of the material Between 50-60°C. Aerobic fermentation time is 15 days. After composting, ferment at 60-65°C to make the water content of the fermented material ...

Embodiment 3

[0022] The carrageenan algal residue organic fertilizer is composed of 0.05% monoammonium phosphate, 30% auxiliary materials, 0.1% microbial fermentation agent and the balance is carrageenan algal residue.

[0023] In terms of weight percentage, take carrageenan algae residue with a moisture content of 82%, press and dehydrate to make the moisture content reach 68%, add 0.05% monoammonium phosphate, adjust the pH of the material to 7.8, and then add 30% bran And 0.1% microbial starter, all auxiliary materials are fully mixed with compost materials. When the temperature of the fermentation pile reaches above 60°C, turn the pile in time to increase air permeability and add a certain amount of water. Turn the pile once on the 3rd, 5th, 7th, 9th, 11th, and 13th days after inoculation respectively. And maintain the material temperature between 60-65 ℃. Aerobic fermentation time is 18 days. After composting, ferment at 60-70°C to make the water content of the fermented material le...

Abstract

The invention relates to the field of biological fertilizers and in particular discloses a carrageenan algae residue organic fertilizer and a preparation method thereof. The carrageenan algae residue organic fertilizer consists of the following components in percentage by weight: 0.05 to 0.5 percent of monoammonium phosphate, 0 to 30 percent of auxiliary materials, 0.025 to 0.5 percent of microbial fermentation agent and the balance of carrageenan algae residue. The preparation method comprises the following steps of: adding the monoammonium phosphate into the carrageenan algae residue according to the proportion, regulating the pH value of materials to be 7.0 to 8.0, adding bran and the microbial fermentation agent into the materials, fully mixing and stirring, fermenting a compost, turning the pile in time and supplementing the moisture when the fermentation temperature is 65 to 68 DEG C, turning the pile once on 3rd, 5th and 7th days after inoculation respectively, and maintaining the fermentation temperature of the compost to 45 to 65 DEG C, wherein the aerobic fermentation time is 12 to 20 days; and after the composting is finished, ensuring that the water content of the fermented materials is 20 to 25 percent at the temperature of between 50 and 70 DEG C to obtain the carrageenan algae residue organic fertilizer. By the method, the waste is turned into wealth, the high-efficiency and low-cost organic fertilizer is obtained, the environmental pollution is also treated, and the ecological balance is better kept.

Description

technical field [0001] The invention relates to the field of biological fertilizers, in particular to a carrageenan algae residue organic fertilizer and a preparation method thereof. Background technique [0002] my country is a large ocean country with rich seaweed resources and a variety of tropical algae rich in carrageenan. my country has nearly a hundred carrageenan processing enterprises with an annual output of more than 4,000 tons of carrageenan. When extracting seaweed carrageenan, a large amount of Algal residue waste, the treatment of algal residue has become a major problem. Studies have shown that seaweed contains a large amount of more than 40 kinds of mineral elements such as K, Ca, Mg, Fe, Zn, and I. Due to the addition of a large amount of potassium chloride and other additives in the production process of extracting carrageenan, the algae residue is rich. Containing K element, we determined that the potassium content, magnesium content and calcium content i...
