Embodiment 1

[0028] A preparation method of livestock and poultry manure biochar-based microbial fertilizer, comprising the following steps:

[0029] (1) Pretreatment of livestock and poultry manure samples: collect the solid matter of livestock and poultry manure after dry-wet separation in large-scale farms, dry them at 70°C, crush them into granules, and screen them through an 80-mesh sieve. The required animal manure can be selected from at least one of cow manure, pig manure, chicken manure or sheep manure.

[0030] (2) Biogas residue collection and fermentation: collect the biogas residue after anaerobic fermentation in a large-scale biogas project, carry out aerobic fermentation for 15 days, turn the pile 3 times a day during the fermentation process, and the organic matter content in the biogas residue is greater than 40%.

[0031] (3) Pyrolytic carbonization: Using high-purity nitrogen as a protective gas, put the solid matter of livestock and poultry feces treated in step (1) in ...

Abstract

The invention relates to the technical field of agricultural solid waste treatment and resource utilization, in particular to a preparation method of poultry and livestock manure charcoal-based microbial fertilizer. The method comprises the following steps of (1) poultry and livestock manure sample pretreatment; (2) biogas residue collection and fermentation; (3) pyrolysis carbonization; (4) microbial fermentation; (5) mixed granulation; (6) packaging and encapsulation storage. The pore structures with rich nutrition elements and complicated charcoal of the poultry and livestock manure are organically combined with the microbial soil restoration effect; the environment-friendly and efficient charcoal-based microbial fertilizer is prepared.

Description

technical field [0001] The invention relates to the technical field of agricultural solid waste treatment and resource utilization, in particular to a preparation method of livestock and poultry manure biochar-based microbial fertilizer. Background technique [0002] With the rapid development of intensive breeding industry, my country's annual output of livestock and poultry manure is about 3.8 billion tons, ranking first in the world. Antibiotics are widely used in livestock and poultry farming in my country. Because animals cannot completely absorb or metabolize antibiotics in feed, most antibiotics are enriched in the form of raw drugs in livestock and poultry manure. After the livestock and poultry manure carrying a large amount of antibiotics is applied to the soil , easily lead to the emergence of drug-resistant bacteria and resistance genes (ARGs) in the environment, posing a huge threat to human health. In addition, due to factors such as improper feeding management...
