Matters needing attention during the fermentation of organic fertilizer manufacturing process:
1. Requirements for fermentation raw materials
Fermentation raw materials (such as agricultural wastes such as feces) are preferably fresh without natural recycling.
2. Accessories requirements
Fermentation auxiliary materials (such as straw, rice bran, etc.) should have a moderate water content, strong water absorption, suitable particles or length, and should not be too large. The amount of addition should be determined according to the moisture content of the fermentation raw material.
3. The strains should be removed
Organic fertilizer fermentation strains require at least 50 grams (1 or 2) for one ton of raw materials. Considering that it cannot be evenly spread on the fermentation materials, when using it, first mix 50 grams of strains with 500 grams (1 kg) Stir any kind of raw materials such as wheat drum, sawdust, oil dry, rice bran, etc., and then sprinkle it into the fermentation material, and then stir and pile up the fermentation evenly.
4. The fermentation moisture is adjusted well
The moisture adjustment of raw and auxiliary materials is the most important, which is related to the success or failure of fermentation. Moisture requirements are: after the original accessories are mixed, hold them in a ball and fall on the ground into two pieces. The proportion of general auxiliary materials (such as straw, rice straw, etc.) is 10% to 30% (weight percentage with raw materials). If calculated according to the volume ratio of the two, it is generally 2 parts of raw materials and 1 part of auxiliary materials.
5. The length, width and height of the fermentation stack should meet the standard
It is required that the width of the fermentation product is not less than 1.5 meters, the height is not less than 1 meter, and the length is not limited.
