Detailed explanation of organic fertilizer fermentation technology

Organic fertilizer is an organic fertilizer that is processed from organic solid waste (including organic waste, straw, livestock and poultry manure, cake, agricultural and sideline products and food processing raw solid waste) after fermentation, deodorization and complete decomposing of biological fertilizer strains. It can condition soil, activate the activity rate of microorganisms in soil, overcome soil compaction, and increase soil air permeability. Improve soil fertility, so that food crops, cash crops, vegetables, fruits and vegetables can be greatly increased.

The production method can be made according to local raw materials, such as municipal solid waste and various crop straws, leaves and weeds, melons and vines, straw, pine husks, peanut shells, sawdust, rice husk powder, bran, fruit bagasse, dry bagasse , edible fungus residue, distiller’s grains, brewer’s grains, sugar residue, vinegar residue, starch residue, cassava residue, citric acid residue, soy sauce residue, monosodium glutamate residue, powder residue, bean curd residue, medicine residue, oil residue, oil cake residue, bran, Cotton rapeseed meal, moldy feed, sludge, sugar factory brewery sludge, slaughtering scraps, stagnant (swill) water, leftover food, human and animal manure and other wastes.

Fermentation fertilizer operation process:

1.The general dosage of bacteria is 0.2%-0.5%.

2.Raw and auxiliary materials and requirements: Main materials: fruit bagasse, dry bagasse, edible mushroom residue, distiller’s grains, brewer’s grains, sugar residue, vinegar residue, starch residue, wood pulp residue, citric acid residue, soy sauce residue, monosodium glutamate residue, powder residue , bean curd residue, medicine residue, oil residue, oil cake, bran, cotton rapeseed meal, moldy feed, sludge, sugar factory brewery residue sludge, slaughtering scraps, slop (swill) water, leftover food, human and animal bulk materials such as feces.

Accessories: all kinds of crop straws, leaves and weeds, melons and vines, straw, pine husks, peanut shells, sawdust, rice husk flour, bran, etc. can be dried, crushed, and high in carbon.

3.The ratio of raw and auxiliary materials: main material: auxiliary material=5:1-3:1.

4.The moisture is controlled at 60-65%, and the material is just clumped out of the water.

5.Mix all the bacteria, main ingredients and auxiliary ingredients evenly as required

6.When the ambient temperature is above 15°C, the material should be piled up to no less than 4 squares at a time. It should be piled into a pile with a width of 1.5 to 2 meters, a height of about 0.6 meters, and an unlimited length, and use a stick to make air holes in the pile.

7.When the heap temperature rises to 50℃, it will start to overturn, once a day, if the heap temperature exceeds 65℃, it will be overturned again. The temperature is controlled below 70 ℃, and the temperature is too high to affect the nutrients.

8.Decomposed sign: the heap temperature is lowered, the material is loose, there is no original odor of the material, there is a slight ammonia smell, and white mycelium is produced in the heap.

9.Decomposed raw fertilizer: directly used to produce commercial organic fertilizer, bio-organic fertilizer, organic-inorganic compound fertilizer, bio-organic-inorganic compound fertilizer, etc.

Notice:

① The total moisture of the fermentation mixture should be controlled at 60-65% depending on the ratio of the increase or decrease of the moisture. Too high or too low is not conducive to fermentation, too little water, slow fermentation; too much water will cause the ventilation difference to heat up slowly and produce odor. How to judge whether the moisture is suitable or not: Grasp a handful of materials tightly, see the watermark between the fingers but not dripping, and it will disperse when it falls.

②If 1 kg of urea or 10 kg of superphosphate is added per ton, the fermentation effect.
