Fermentation Method of Manure Organic Fertilizer Production Line
Fermented livestock manure is a high-quality organic fertilizer with rich nutrient content. There are both a large amount of organic matter and a high content of three essential nutrients. Organic matter contains 25.5% of stars, 1.63% of nitrogen, 1.54% of phosphorus, and 0.35% of potassium. Manure does not decompose and is applied directly to crops:
- Infect pests. Stool contains E. coli and square nematode.
- Destroy crops. After the unfermented raw manure and other organic materials are applied to the ground, when the fermentation conditions are available, they are fermented under biological activities. When the fermented part is close to the root and the crop plant is small, the heat generated by the fermentation will affect the growth of the crop , Burn the roots of crops.
- Odor. During the decomposition process, gases such as methane and ammonia are produced, which make the soil and crops produce acid and damage the roots of crops.
What is the effect of fermented organic fertilizer (take chicken manure as an example):
- Produce a variety of enzymes to control stubble and root-knot nematodes.
- Contains beneficial microbial flora, which can activate nitrogen in the air, release phosphorus and potassium nutrients, and replenish soil organic matter.
- The soil is soft and easy to cultivate, which promotes soil aggregate structure, releases soil pores, and promotes the growth of roots. Make the soil retain water and fertilizer.
Fermentation method of manure organic fertilizer production line:
The enzymatic process is divided into: composting, heating, turning and throwing, odorless, loose, and fertilizer. When composting, 80% of livestock manure and 20% of straw are crushed and mixed. The mixing ratio of straw and feces can be determined according to the moisture content of the feces. Generally, fermentation requires 65% water content, that is, the hands are kneaded into a ball, water sees through the fingers, but does not drip, and it will dissolve as soon as you let go. Then add corn flour or brown sugar and bacteria to increase the sugar content for the fermentation of the bacteria, so that the multi-dimensional complex enzyme bacteria has an absolute advantage. Add the prepared mixture to the mixer for mixing, mixing-it must be even and thorough without leaving any lumps.
The mixed ingredients are piled into strips with a width of 1.5 meters to 2 meters, a height of 0.8 meters to 1.2 meters and a length of not less than 5 meters. During the fermentation process, pay attention to proper oxygen supply and turn over (turn over several times when the temperature rises to 75℃or above), and control the temperature rise at about 65°C. Too high temperature will affect the fermentation product.
The moisture of the fermented materials should be controlled at 60~65%. Too high or too low is not conducive to fermentation. Too little water makes fermentation slow. Too much water will cause poor ventilation, slow heating, and produce odor.
The initial temperature of fermentation is 50℃-80℃, which eliminates the odor of chicken manure and other bacteria. In the middle of fermentation and composting, the material becomes loose and dry, with white hyphae. During the fermentation maturity period, the materials give off the scent of koji, and the bacterial fertilizer will be fermented and mature.
