The invention discloses a method for preparing a sludge organic fertilizer and a seedling substrate formula, and particularly relates to the technical field of production of organic fertilizers from domestic sludge, and the specific steps are as follows: S1, raw material pretreatment: firstly, treating collected sludge and corn straws, detecting internal moisture of the sludge, crushing the corn straws, and then preparing a corresponding fermentation inoculant. The raw material sludge dewatering process is finely divided, and the sludge dewatering efficiency is effectively improved, so that the time consumed in the whole sludge strip stack composting process is shortened, the composting method is rapid in temperature rise, the temperature can be raised to 75 DEG C after about 3 days of composting, the high-temperature duration can reach 15 days or above, the production cost is reduced, and the organic matter content of the compost after fermentation is completed is obviously higher than that in commercial org
