The invention discloses a special organic/inorganic compound fertilizer for corn and a preparation method thereof, belonging to the fields of agricultural resource recycling and environment protection. The invention combines two aspects of the agricultural waste reclamation utilization and novel fertilizer manufacture; inorganic chemical fertilizer is added into the chicken manure and tikitiki according to growth characteristics and nutrient requirement of corn to prepare nutritional organic/inorganic compound fertilizer. The organic matter content of the compound fertilizer reaches 20.35-24.05%, and the nutrient thereof accounts for 20.92-26.85% of the total nutrient, wherein, nitrogen content is 8.72-10.13%, phosphorus pentoxide content is 3.85-7.07% and potassium oxide content is 8.35-9.65%. The invention solves the problem of post processing of chicken manure, avoids rural environment pollution, has long-acting fertilizer property of the organic fertilizer and quick-acting fertilizer efficiency of the inorganic fertilizer, obvious production increasing effect, simple preparation process and low requirement on machinery equipment manufacture, saves cost, and is beneficial for large-scale popularization and application.
