How to ferment pig manure into organic fertilizer?

Pig manure is a good raw material of organic fertilizer. If pig manure is directly returned to the field, it will damage the roots and burn seedlings, which is easy to cause crop yield reduction. The solution to solve the problem of pig manure pollution in large-scale farms is to use complete sets of organic fertilizer equipment to process organic fertilizer, which is highly mechanized and easy to master. Generally, fermentation tank should be established for pig manure fermentation organic fertilizer. The following is the fermentation process of pig manure processing organic fertilizer Let's introduce it. I hope it will be helpful to you.

Pig manure was mixed with straw, sawdust and mushroom residue in proper proportion (feces accounted for 8-90%, others accounted for 10-20%). 1 ton of material (about 2.5 tons of fresh material) is added with 1 kg of pig manure starter, diluted by 1 kg of pig manure starter and 5 kg of rice bran (or wheat bran, corn flour and other substitutes), and then evenly sprinkled into the material pile, mixed fermentation can be achieved.

During the fermentation process, proper oxygen supply and composting should be paid attention to. The temperature should be controlled at 55-65 ℃. If the temperature is too high, the nutrients will be affected. The moisture content of fermentation materials should be controlled at 60-65%, too high or too low is not conducive to fermentation, too little water leads to slow fermentation; too much water will lead to poor ventilation, slow temperature rise and odor.

In general, the whole fermentation process can be completed after 5-7 days, such as complete deodorization, fermentation, sterilization, etc. The finished organic fertilizer is fluffy, dark brown, slightly flavored with wine or soil, and rich in nutrients. It is safer and more convenient to put into farmland. It has higher value added to fruits, vegetables, cash crops and seedlings.

In the process of fermentation, pig manure composting and fermentation machine is used to repeatedly flip, ventilate, supplement oxygen and control water, so as to reduce water content and carry out aerobic fermentation. At the same time, by adding auxiliary materials, the content of trace elements injected into the materials can be increased.

After the completion of the initial fermentation, the fermentation tank is moved to carry out secondary aging, which takes a short time, and is usually completed in a few days. The secondary aging is to increase the activity of organic fertilizer.

The optimal method for pig manure composting is to use pig manure composting method in pig farm. It can be used for continuous fermentation of pig manure in pig farm. At the same time, it has a relatively good maintenance of organic nutrients. At the same time, it is easy to industrialize pig manure.
