The invention discloses a composting method of recyclable organic fertilizer. The organic fertilizer is prepared from the following components in percentage by mass: 30-35 percent of smashed straw, 20-25 percent of livestock and poultry dung, 20-25 percent of mushroom residues, 10-15 percent of mushroom bran and 5-10 percent of microbial agent. The composting method comprises: (1) smashing: smashing the smashed straw, the mushroom residue and the mushroom bran to form 55-60-mesh powder; (2) mixing: mixing the powder with the livestock and poultry dung evenly, and adding a proper amount of water, thus forming a mixture; (3) fermenting: adding the microbial agent into the mixture, stirring evenly, and stacking for 10-15 days under room temperature, thus forming a fertilizer; (4) drying in the sun, prilling and bagging. In this way, the recycling use of the agricultural organic fertilizer can be realized, and the prepared organic fertilizer is odourless, loosened and dry, is pollution-free in a composting process, does not harm the environment, and is recyclable.
