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

Abstract

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.

Description

technical field [0001] The invention belongs to the field of fertilizer processing, and in particular relates to a chicken manure and pig manure mixed fermentation fertilizer and a preparation method thereof, and also relates to a bio-organic fertilizer composed of chicken manure and pig manure mixed fermentation fertilizer and a preparation method thereof. Background technique [0002] With the rapid development of my country's national economy and the continuous improvement of people's living standards, people's demand for meat, eggs and milk has gradually increased, which has led to the rapid development of my country's aquaculture industry. According to the latest report of the Food and Agriculture Organization of the United Nations, the chicken industry in mainland my country is well-developed, and the number of chickens raised has ranked first in the world for three consecutive years. Last year, the number of chickens raised exceeded 3 billion, accounting for 24% of the...

AI Technical Summary

Problems solved by technology

However, due to the differences in the types and contents of organic matter, nitrogen, phosphorus, potassium and other trace elements in chicken manure and pig manure, the fertilizer produced by fermentation is not suitable for many crops, and the nutrients of bio-organic fertilizer obtained by fermentation are either As much as is contained in the feces, or it needs to be added

The large amount of nitrogen, phosphorus, and potassium added is relatively easy to be uniform, but the amount of medium and trace elements is small, so it is difficult to mix evenly

Moreover, due to the fine texture and poor air permeability of pig manure, a large amount of straw powder, rice bran and other substances need to be added for separate fermentation, and excessive addition of these substances will reduce the nutrient content and fertilizer efficiency of the fertilizer.

In addition, fermenting pig manure and chicken manure separately and then mixing them in proportion requires additional fermentation sites, additional fermentation equipment, and additional production personnel, which will inevitably increase the cost of fertilizer production.
