The method of making pig manure organic fertilizer by using turning and throwing machine

The method of making pig manure organic fertilizer by using turning and throwing machine:
1. Feeding and adding bacteria: Prepare the manure that needs to be fermented. It is best to use fresh pig manure (the fermentation effect of fresh manure is better than that of old manure), such as: about 1 ton of fresh pig manure plus 0.25 kg of pig manure starter. First, mix the pig manure starter with rice bran (or corn flour, wheat bran) in a ratio of 1: 5~10 for use.
2. Build a pile of pig manure: Build a pile of prepared pig manure while spreading bacteria. The height and volume of the pile should not be too short or too small. Requirements: The pile height is 1.5-2 meters, the width is 2 meters, and the length is not limited.
3. Adjust moisture. The moisture content of fermented pig manure should be controlled at 40-65%. Judgment of moisture content: Grab a handful of pig manure tightly with hands, see watermark between fingers but not dripping water, and it is advisable to disperse after landing. Less water, slower fermentation, more water and poor ventilation will also lead to the work of “septic bacteria” and produce odor. Therefore, it is necessary to grasp the moisture content.
4. Start temperature. The starting temperature should be above 15 ℃, and it can be operated in four seasons without being affected by the season. In winter, try to ferment indoors or in a greenhouse, and the fermentation temperature should be controlled below 70-75 ℃.
5. Mix well and ventilate. Pig manure starter requires aerobic fermentation. Therefore, oxygen supply measures should be increased during the operation process, and it is advisable to mix well, turn the heap, and ventilate. Otherwise, it will lead to anaerobic fermentation and produce odor, which will affect the effect of fertilizer.
6. Fermentation is completed. Generally, after 48 hours of pig manure accumulation, the temperature rises to 50~60°C, and it can reach above 65°C on the third day. At this high temperature, the pile must be turned over once. In general, during the fermentation process of pig manure, there will be two occurrences of 65°C. At the above high temperature, the fermentation can be completed by turning the heap twice, and the fermentation can be completed within a week normally. The material is dark brown, and the temperature begins to drop to room temperature, indicating that the fermentation is complete.
