Enhanced culture medium as well as preparation method and application thereof

The invention discloses an enrichment culture medium as well as a preparation method and application thereof, and relates to the technical field of culture media. The enrichment medium comprises the following components: monopotassium phosphate, dipotassium phosphate, sodium chloride, anhydrous magnesium sulfate, tryptone and glucose. The enrichment culture medium is applied to enrichment culture of riemerella anatipestifer, pasteurella, salmonella and/or escherichia coli. The enrichment medium disclosed by the invention has a relatively good enrichment effect on four bacteria including riemerella anatipestifer, pasteurella, escherichia coli and salmonella, the preparation work of the enrichment medium can be simplified, and the preparation cost is low; the problems that the preparation work of the culture medium is complicated and the cost is relatively high in practical application due to non-uniformity of the existing enrichment culture medium for four bacteria are solved. 本发明公开了一种增菌培养基及其制备方法和应用，涉及培养基技术领域。
