The invention discloses a preparation method of a bioorganic fertilizer. The method is characterized by adopting a complex microorganism bacterium agent formed by bacillus subtilis, aspergillus oryzae, trichoderma reesei, phanerochaete chrysosporium and geobacillus stearothermophilus as a decomposition agent to degrade straws to prepare the bioorganic fertilizer. The preparation method has the beneficial effects that the strain composition of the complex microorganism bacterium agent is new flora composition, which takes full advantage of the physiological activities of strains to generate cellulose, hemicellulose and biological enzymes, such as ligninase, to accelerate the decomposition process of straws, thus preparing the bioorganic fertilizer; the organic straw fertilizer prepared by the preparation method is used as a base fertilizer, so that the contents of available nitrogen, rapidly available phosphorus, potassium and organic matters in soil are higher than those of available nitrogen, rapidly available phosphorus, potassium and organic matters in the soil in which straws are directly used and fertilizers are not applied; the urease activity and cellulase activity of the soil are obviously improved compared with those of the soil in which straws are directly used and fertilizers are not applied.

The invention relates to a rural solid waste mixed aerobic composting method, which comprises the following main steps: A) cutting straws to make the straws have the length of 5 to 10cm, spraying compound bacteria on a straw stack, simultaneously adjusting the moisture content of the straws to between 50 and 55 percent with percolate generated in a step B of the previous composting process, and naturally ventilating and fermenting for 10 to 15 days, wherein the spraying amount of the compound bacteria meets the condition that the ratio of the bacteria volume to the dry weight of the straws is 4 to 5mL / kg; B) mixing degradable organic matters sorted from domestic garbage and the pre-fermented straws in the step A, respectively adjusting the initial moisture content and C / N to between 50 and 65 percent and between 22 and 35 after the mixing, performing the first composting for 3 to 5 days, and introducing tail gas generated in the step into the stack of a step C; C) mixing the compost in the step B and livestock manures, adjusting the initial moisture content to between 50 and 60 percent after mixing, and performing the secondary composting for 3 to 5 days; and D) performing the composting on the compost of the step C for the third time for 5 to 7 days, and adjusting the moisture content of the stack with percolate generated in the step C to maintain the moisture content of the compost between 45 and 50 percent.
