Method subjecting crop straw and poultry and livestock manure to mixing and fast fermentation to produce organic fertilizer

The invention discloses a method subjecting crop straw and poultry and livestock manure to mixing and fast fermentation to produce organic fertilizer. The method includes: using three different microbial agents which include nitrogen-fixing bacteria, lactobacillus and saccharomycetes to perform substep stacking anaerobic fermentation on mixed materials formed by the poultry and livestock manure and the crushed crop straw at 70-80 DEG C, 35-45 DEG C and 25-35 DEG C, drying, crushing, and packaging to obtain the organic fertilizer. The method has the advantages that the efficiency of organic-fertilizer production using the crop straw and the poultry and livestock manure as the raw materials can be increased, production time can be reduced, and the produced organic fertilizer is sufficient and comprehensive in nutrition, capable of improving the water-retaining ability, fertilizer-retaining ability and breathability of soil, capable of reducing soil hardening and capable of optimizing thesoil structure and the c
