The invention discloses a microelement nutrition reinforcing method capable of promoting development of larval of Macrobrachium nipponense. The method includes: using high concentrated chlorella as microelement enriched carriers, and preparing a certain concentration of a copper sulfate solution and a zinc sulfate solution; using the solutions to perform enrichment of microelement copper and zinc on the chlorella, putting the chlorella into a water tank with artemia after enrichment is completed, and adding emulsified fish oil and selenium yeast into the water tank to reinforce the artemia; and finally feeding the larval of the Macrobrachium nipponense with the reinforced artemia. The microelement nutrition reinforcing method capable of promoting development of the larval of the Macrobrachium nipponense can perform microelement reinforcement on the artemia for the the larval of the Macrobrachium nipponense, and can feed the larval of the Macrobrachium nipponense with the microelement reinforced artemia to significantly improve the survival rate of the larval.
