Pig manure is rich in nutrients, containing 15% of organic matter, 0.5% of nitrogen (N), 0.5-0.6% of phosphorus (P2O5), and 0.35-0.45% of potassium (K2O). Pig manure is fine in texture, contains more nitrogen and is easily The microorganisms break down and release effective nutrients that can be absorbed and used by the animals. If used, it will become a good fish (shrimp) feed. However, live pig manure contains parasite eggs and some toxic substances and pathogens. Therefore, fish (shrimp) cannot be fed directly from pig manure. Must be professional fish (shrimp) feed fermentation agent (Golden Baby microbial fermentation agent) in order to become a safe and environmentally friendly and nutritious feed. The specific fermentation method is as follows:
1, material ratio. 1.5 tons of pig manure (about 3 tons of fresh manure), plus 1 kilogram of gold baby starter, starter and rice bran should be mixed with 1:5 ratio, and then evenly spread into the pig manure heap, mixing evenly. It is best to add 25% straw or mushroom residue to adjust the ratio of carbon to nitrogen.
2. Material builds a heap. In the heap can not do too small, too short, too small will affect the fermentation, the height of the flat trapezoid stack in the 1.2 meters to 1.5 meters (spigot conical heap 1.5 to 2 meters), width 2 to 2.5 meters, length in 2 ~ More than 4 meters of heap fermentation effect is better.
3, temperature requirements. The start-up temperature should be better than 15°C (it can be operated in all seasons, not affected by the climate of the north and the south, and in the winter, try to start fermentation in the interior or in the greenhouse; the cold regions in the northeast should start the fermentation according to the technician's instructions).
4, water requirements. The moisture of the fermentation material should be controlled at about 60%. Too high or too low is not conducive to fermentation, too little water, slow fermentation; too much water can lead to poor ventilation, slow heating, and produce odor. To adjust the moisture content of the material: If the moisture content is too high, add dry straw such as straw powder, mushroom residue, and bran bran. Whether the water is suitable or not is judged by hand: hand grasps a handful of material, the finger sees the watermark but does not drip, the landing is casual.
5, turning ventilation. During the fermentation process, attention should be paid to proper oxygen supply and turning over (when the temperature rises to 60-70°C or above, it must be tipped over in time, generally requiring 2 to 3 turnovers). The temperature rise is controlled at about 65°C, and the temperature is too high to affect nutrients.
6, the completion of fermentation. The process of complete deodorization, fermentation, and insecticidal sterilization can generally be completed within one week. The material was dark brown and the temperature began to fall to room temperature, indicating that the fermentation was completed. If straw, mushroom slag, and excessively high cellulose content are excessive, the fermentation time should be prolonged until sufficient decomposed.
The use of gilt microbial starter to feed the pig manure will not only provide cheap and high-quality nutrition for the fish (shrimp), but also raise pigs and fish to promote each other and form a good ecological cycle.
