The invention belongs to the technical field of powder metallurgy, and particularly relates to a production method of spherical copper powder containing nanometer dispersion strengthening phases. The production method comprises the following steps that nano-phase micro powder is placed into absolute ethyl alcohol to be processed through ultrasonic dispersion, and then copper powder is added to the ethyl alcohol step by step and is sufficiently stirred, so that nano-phase particles are adsorbed on the surface of the copper powder; a mixture is placed in a vacuum drying oven, and dry copper powder with adsorbed nano-phases can be obtained after the ethyl alcohol completely volatilizes; the dry copper powder is pressed to form cake-shaped materials, the cake-shaped materials are put into molten copper or copper alloy, and the nano-phase particles adsorbed on the surface of the copper powder are gradually dispersed to the molten copper or copper alloy in the melting process of the cake-shaped materials; and the molten copper or copper alloy with the dispersed nano-phase particles is fed into a hopper to produce copper powder with the method of gas atomization, so that the dispersion strengthening spherical copper powder containing the nanometer particles is obtained. The dispersed phases in the spherical copper powder manufactured by means of the production method are uniformly distributed, the technology is simple and easy to conduct, and the production method is suitable for industrial production.
