The invention provides a fermentation inoculum for decomposed crop straw. The fermentation inoculum comprises the following raw materials in parts by weight: 10-30 parts of an active composition and 70-90 parts of a carrier. The active composition comprises trichoderma viride, trichoderma longibrachiatum, bacillus subtilis, aspergillus niger and microzyme with the weight ratio of 1:0.8-1.2:1.8-2.5:0.8-1.2:0.8-1.2. The carrier comprises animal dung, bran, rice bran and calcium carbonate with the weight ratio of 1:1.2-1.8:2-3:3-5. The invention also provides a preparation method for the fermentation inoculum for decomposed crop straw. The fermentation inoculum is capable of accelerating softening and decomposing of various straws, efficiently decomposing cellulose, hemicelluloses and lignin in crop straws and improving soil fertility.
