Pig manure fermentation method

1, put fresh pig manure and pig urine into the fermenter, then add calcium superphosphate, the ratio of pig manure and calcium superphosphate is 100 to 3, and then add ferrous sulfate, add 0.5 kg of ferrous sulfate per 100 kg of feces and urine;

2, add accelerated fermentation bacterial agent: put 0.5 kg of accelerated fermentation bacterial agent per 1,000 kg;

3, mix pig manure well, mixing Evenly covered with a thin layer of field soil, blocking the fermentation of nitrogen gas volatilization into the air, to ensure the environmental quality of pollution-free fruit and vegetable production;

4, if it is early spring, to set up bamboo arches on the pool, laying plastic trellis film, four sides of the soil pressed tightly, set up small arches can play a role in warming and heat preservation to accelerate the fermentation of swine manure;

5, when the material is black-brown, swine manure temperature begins to drop to room temperature, indicating that fermentation is complete.
