Chicken manure/pig manure mixed fermentation fertilizer and preparation method thereof

The invention relates to the field of fertilizer processing, particularly a chicken manure/pig manure mixed fermentation fertilizer and a preparation method thereof. The preparation method comprises the following steps: mixing chicken manure and pig manure in different ratios, adding effective microorganisms, straw powder or rice bran, calcium superphosphate and peat soil, compounding, and fermenting to obtain the chicken manure/pig manure mixed fermentation fertilizer. The nutritional ingredients of the chicken manure and pig manure are complementary, and the long-acting nutritional ingredients of the chicken manure are combined with the quick-acting nutritional ingredients of the pig manure, so that the nutritional ingredients of the chicken manure/pig manure mixed fermentation fertilizer are more comprehensive, reasonable and uniform than the single chicken manure or pig manure fermentation fertilizer, and more conform to the crop absorption law. By using the preparation method of chicken manure pig/manure mixed fermentation, on the premise of not prolonging the fermentation time, both of the two different substances can be completely fermented. Compared with the method of respectively fermenting chicken manure and pig manure and compounding, the preparation method provided by the invention reduces the fermentation field and equipment, shortens the fermentation time, and saves the labor cost.
