1. Mostly it is a moisture adjustment problem. First, see if the moisture is greater than 60%. If so, add corresponding excipients to adjust to 60% and mix well. If it is less than 40%, add water or fresh feces to adjust to 60% and mix well.
2. C/N ratio imbalance can cause the temperature to not rise at 32-48 degrees Celsius, usually with a ratio of 25-30; equivalent materials or inorganic elements can be added to adjust.
3. If the pH is too high or too low, it can cause no warming or the temperature to remain below 50 degrees for a long time. Adjust the pH value of the fermentation product. Common items are salty. To reduce the pH value of the product, add one of the following in an appropriate amount: H3PO4 (phosphoric acid) KH2PO4 (potassium dihydrogen phosphate) FeCL3 (ferric chloride) FeSO4 • 7H2O (alum). Common items of the pH value of the fermentation product are acidic. To increase the pH value of the product, add one of the following in an appropriate amount: CaO (quicklime) NaOH (caustic soda) K2HPO4 (dipotassium hydrogen phosphate) Addition method: Dissolve in water and spray.
4. Poor air permeability, you can add straw powder or support it at the bottom and turn it over again;
5. Stir unevenly, just stir well.
6. Pile body: width 1.5 meters-2 meters is appropriate, height 0.8 meters-1.5 meters. Deodorization can be done 3 days after the temperature rises;
7. In places with strong winds in the mountains such as Sichuan, Yun, Guizhou, and Chongqing, especially the organic raw materials used for growing tobacco and tea leaves should be stacked on the ground. N ventilation ducts with a width of about 20 cm and a depth of 25 cm should be left at the bottom, and the surrounding areas should be covered with oilcloth or other materials.
