  The present invention relates to a solid catalyst for propylene polymerization and a method of producing a propylene polymer or copolymer using the solid catalyst for propylene polymerization, and provides a solid catalyst which prepares a dialkoxymagnesium carrier and is formed of a carrier produced through a reaction of the carrier with a metal halide, a titanium halide, an organic electron donor, etc., and a method of producing a propylene polymer or copolymer through copolymerization of propylene-alpha olefin using the solid catalyst, wherein the dialkoxymagnesium carrier has an uniform particle size range of 10 to 100 µm and a spherical particle shape by adjusting injection amounts, injection numbers, and reaction temperatures of metal magnesium, alcohol and a reaction initiator during a reaction process of metal magnesium and alcohol. Particularly, the present invention not only can produce polypropylene having high activity, excellent stereoregularity and hydrogen reactivity by performing a polymerization process through a solid catalyst which uses an internal electron donor including a carbonyl group and an alkoxy group out of two or more organic electron donors and is suggested in the present invention and a method of producing a propylene polymer or copolymer using the solid catalyst, but also can produce a block copolymer with a high rubber content by performing a copolymerization process with an alpha olefin.
