The present invention discloses an organic inorganic compound fertilizer for preventing and 5 controlling rice seedling blight and its preparation method, belonging to the field of fertilizer technology. The raw materials of the fertilizer include the following components in mass parts: 20-25 parts of ammonium chloride, 20-25 parts of potassium chloride, 15-20 parts of calcium superphosphate, 5-10 parts of ammonium sulphate, 3-5 parts of ammonium molybdate, 50-60 parts of earthworm manure organic fertilizer, 15-20 parts of humic acid, 10-15 parts of attapulgite 10 clay powder, 5-8 parts of chitosan oligosaccharide, 3-5 parts of dandelion extract, 1-3 parts of Jiang gardenia extract, and 3-5 parts of complex microbial community. The synergistic cooperation of each component in the compound fertilizer can not only make the acidic effect of the compound fertilizer last for a long time, resist washing, suppress the return of salt and alkali underground, adjust the soil structure, inhibit the propagation of Fusarium oxysporum, create a 15 suitable growth environment for the growth of roots and stems, but also improve the disease resistance of rice seedlings and effectively reduce the incidence rate of rice seedling blight.
