The invention relates to the technical field of microbial agent sewage treatment, and discloses a heavy metal passivation type organic material decomposition agent and a preparation method thereof, the heavy metal passivation type organic material decomposition agent comprises 10-15 parts of aspergillus nidulans powder, 16-25 parts of bacillus subtilis powder, 12-16 parts of staphylococcus amber powder, 20-25 parts of charcoal, 40-50 parts of decomposed pig manure, and 2-5 parts of urea. According to the scheme, the decomposition agent obtained by combining the three microorganisms, the biochar, the decomposed pig manure and the urea can stimulate growth and development of crops, increase soil nutrients, improve the utilization rate of a chemical fertilizer, reduce the content of exchangeable heavy metals in soil or fermentation raw materials, effectively improve the soil quality and realize safe production. In the using mode, the decomposition agent not only can be directly applied to land, but also can be u
