Preparation method and application of livestock urine deodorization fungicide

The invention discloses a preparation method and application of a livestock urine deodorizing bacterial agent, and relates to the technical field of deodorizing bacterial liquid, the livestock urine deodorizing bacterial agent comprises 30-50% of humic acid, 8-12% of photosynthetic bacteria, 5-10% of bacillus, 10-25% of denitrifying bacteria and 10% of lactic acid bacteria, the preservation number of the livestock urine deodorizing bacterial agent is CGMCC No.5959, and 10% of bacillus megaterium Z3 with the preservation number of CCTCC NO: M2018660 or/and a culture of the bacillus megaterium Z3 or/and a processed product of the bacillus megaterium Z3. The biological deodorant can effectively reduce the content of hydrogen sulfide gas in livestock manure and urine to achieve the purpose of removing odor, the biological enzyme is a substance which is generated by living cells and has a catalytic effect, the main source of the biological enzyme is a compound enzyme substance extracted from plants, the compound e
