preparation example Construction

[0044] A preparation method of chitin organic fertilizer, comprising the following specific steps:

[0045] a. Raw material pretreatment: dry crustacean raw materials such as shrimp, crab, and pupae, and crush them through a sieve smaller than 6mm for later use;

[0046] b, anaerobic fermentation: mix 10-30% crushed crustacean raw material on a dry basis mass with 10-20% edible fungus residue on a dry basis mass, and 50-80% food factory residue on a dry basis mass, Adjust the moisture content to 50-60%, then add high-temperature-resistant acid-producing bacteria and mix evenly to make the concentration reach more than 100,000 per gram, and seal the anaerobic fermentation for 10-30 days after stacking until the pH value is lower than 4.5;

[0047] c. Aerobic fermentation: Use urea, ammonium carbonate or ammonium bicarbonate to adjust the carbon-to-nitrogen ratio to less than 20:1 for the anaerobic fermented stock, and then add Aspergillus niger, Bacillus, actinomycetes and yeas...

Embodiment 1

[0050] a. Crustacean raw materials such as shrimp, crab and pupa are dried and crushed through a sieve less than 5mm for subsequent use;

[0051] b. Mix 30% of the crushed crustacean raw material on a dry basis with 20% of the edible fungus residue on a dry basis and 50% of the food factory residue on a dry basis, adjust the moisture content to 50%, and then add resistant The high-temperature acid-producing bacteria are mixed evenly so that the concentration reaches 150,000 per gram, and the pH value is lower than 4.5 when the material is sealed and anaerobically fermented for 15 days after stacking;

[0052] c. Add 5 kg of urea to the anaerobically fermented stockpile to adjust the carbon-to-nitrogen ratio to 15:1, and then add Aspergillus niger, Bacillus, actinomycetes and yeast to a ratio of 1 : 50:1:1 mixed decomposing agent for organic materials, mix evenly to make the concentration 600,000 per gram of raw materials, carry out aerobic fermentation, turn over the heap duri...

Embodiment 2

[0054] a. Shrimp, crab, pupa and other crustacean raw materials are dried and crushed through a sieve less than 4mm for subsequent use;

[0055] b. Mix 20% of the crushed crustacean raw material on a dry basis with 10% of the edible fungus residue on a dry basis and 70% of the food factory residue on a dry basis, adjust the moisture content to 55%, and then add resistant The high-temperature acid-producing bacteria are mixed evenly, and the concentration reaches 100,000 per gram of raw material. After stacking and sealing anaerobic fermentation for 25 days, the pH value is lower than 4.5;

[0056] c. Add 10 kg of urea to the anaerobically fermented stockpile to adjust the carbon-to-nitrogen ratio to 10:1, and then add Aspergillus niger, spores, actinomycetes and yeasts in a ratio of 2 : 50:2:2 organic material decomposing agent, mix evenly so that the concentration is 600,000 per gram of raw material, carry out aerobic fermentation, turn over the pile during aerobic fermentati...

Abstract

The invention discloses a preparation method of a chitin organic fertilizer. The preparation method comprises the following steps: carrying out anaerobic fermentation on raw materials to realize acidification and decalcification, carrying out aerobic fermentation to make materials aminated under alkaline conditions in order to form active chitin, and aging to prepare the chitin organic fertilizer. The raw materials comprise 10-30wt% of a shellfish raw material, 10-20wt% of edible fungus residue and 50-80wt% of food plant residue, water is added to make the water content to 50-60%, and the concentration of high temperature resistant acid producing bacteria reaches above 100,000/grams. The preparation method has the advantages of simple operation, low cost and no pollution, and the chitin organic fertilizer prepared through the method has the advantages of high chitosan content, high activity and good use effect.

Description

【Technical field】 [0001] The invention relates to a preparation method of chitin organic fertilizer, which belongs to the technical field of organic fertilizer. 【Background technique】 [0002] In recent years, with the extensive use of chemical fertilizers and pesticides, the number of beneficial insects has decreased, and the supply of chitin from their remains to the soil has also decreased, so the opportunities for plant leaves and roots to be exposed to chitin have also decreased, causing natural The disorder of the chitin cycle disrupts the distribution of soil microorganisms, and the useful bacteria become less, which leads to the increasing occurrence of diseases and insect pests. [0003] Chitin, also known as chitin, chitin, and chitin, has a history of more than 200 years since Professor H. Braconnot discovered chitin in 1811. During this period, with the continuous research of people, the function of chitin in agriculture has gradually been paid attention to, but...
