The invention discloses an organic fertilizer decomposing agent taking activated oyster shell powder as a carrier. A microorganism bacteria liquid is uniformly mixed with activated oyster shell powder according to a weight ratio of 2-3:2, and the obtained mixture is dried at a low temperature to obtain the organic fertilizer decomposing agent. The total effective live bacteria count in the organic fertilizer decomposing agent is 300-500 millions per gram. A preparation method of activated oyster shell powder comprises activating oyster shell powder at 120-240 DEG C for 5-12 h to obtain the activated oyster shell powder. The decomposing agent is high in fermentation efficiency of organic fertilizer raw materials. The activated oyster shell powder is rich in high-activity calcium, so that calcium in the organic fertilizer is enriched, and the calcium utilization rate of crops is increased. 本发明公开了种以活化牡蛎壳粉为载体的有机肥腐熟剂，将微生物菌液与活化牡蛎壳粉按照重量比为2～3:2混匀，经低温干燥后得有机肥腐熟剂，其中，所述有机肥腐熟剂中总有效活菌数为3～5亿/g，所述活化牡蛎壳粉的制备方法如下：将牡蛎壳粉在120-240℃下
