The invention discloses a preparation method of a seedling culture substrate and application of the seedling culture substrate in citrus seedling culture, the preparation method comprises the following steps: S1, bagasse modification: bagasse is placed in an acid solution, then composite plant hydrolase is added for enzymolysis, and a modified bagasse solution is obtained; s2, modifying the rice straws: carbonizing the rice straws in a vacuum environment, and then sieving to obtain rice straw biomass charcoal; s3, preparation of activated sludge: mixing turfy soil with water, adding the composite flora, and performing shake-flask domestication to obtain the activated sludge; s4, preparation of a seedling substrate: mixing the modified bagasse solution, the rice straw biomass charcoal and the activated sludge, and performing natural fermentation to obtain a fermentation substrate; and mixing the fermentation substrate with coco coir and perlite to obtain the seedling substrate. In addition, when the prepared s
