The invention provides a special bacterial manure for peanut planting, which comprises the following components in parts by weight: 5-25 parts of a compound microbial agent, 30-65 parts of dreg composite powder, 5-20 parts of starch and 10-25 parts of bentonite, wherein the compound microbial agent is composed of bacillus subtilis agent, a rhodopseudomonas palustris agent, a trichoderma harzianum agent and a paecilomyces lilacinus agent; the mass ratio of the bacillus subtilis agent to the rhodopseudomonas palustris agent to the trichoderma harzianum agent to the paecilomyces lilacinus agent is 5:2:1:2, and the total effective viable count of the compound microbial agent is10 billion cfu/g. The bacterial manure is mainly used as a base fertilizer, and can change the microenvironment around the roots of peanuts to prevent various plant diseases and insect pests while promoting nutrient absorption of the peanuts, so that the yield and quality of the peanuts are improved.
