This invention discloses a microbial fertilizer containing rare earth elements. The microbial fertilizer is composed of active major strains, chitosan-type carrier, modified protective agent, neutralizer and rare earth element promoter. The major strains include Azotobacter, P / K-leaching bacteria (or silicate bacteria), and cellulose decomposing fungi. The chitosan-type carrier is suitable for both liquid and solid / freeze-dried microbial fertilizers, and can increase the survival rate of the major strains. The rare earth element promoter is chloride or nitrate of rare earth elements, and can increase the survival rate and fertilizing effect. Chitosan can rapidly degrade in natural soil conditions, thus bringing no pollution to soil.
