The invention discloses an organic fertilizer and a preparation method thereof. The preparation method of the organic fertilizer comprises the following steps: mixing straw, which is saturated by adsorbing biogas slurry, with biological carbon and a conditioner to obtain a mixed material pile body, carrying out aerobic fermentation, and spraying the biogas slurry in the fermentation process to obtain the organic fertilizer, and wherein the conditioner is livestock and poultry manure. According to the invention, the biogas slurry and the straw can be recycled, and the straw saturated by adsorbing the biogas slurry, the biological carbon, the conditioner and the biogas slurry are subjected to combined aerobic fermentation, the biomass heat reduced by biomass heat in the composting process, recycling and utilizing of nutrients are realized, and the organic fertilizer can be produced. 本发明公开了一种有机肥及其制备方法。本发明有机肥的制备方法，包括如下步骤：将所述吸附沼液饱和后的秸秆、生物炭和调理剂混合得到混合物料堆体，进行好氧发酵，并在所述发酵过程中喷淋沼液，即得到有机肥；所述调理剂为畜禽粪便。本发明能资源化利用沼液和秸秆，通过吸附饱和沼
