The invention discloses an defin polymerization catalyst loaded on spherical MgCl2-alcohol-organic complexing agent camier and its preparation method. Said method includes the following steps: under the protection of argon gas using TiCl4 and MgCl2-alcohol-organic complexing agent spherical carrier, stirring them at -30 deg.c-0 deg.C in reaction still and making them produce reaction for 10-30 min., heating to 60 deg.C-80 deg.C, adding internal doner residues, and more heating to 90 deg.C-140 deg.C, thermostatically stirring and making reaction for 1-3 hr., then removing liquid phase, adding TiCl4 to make treatment once, and removing liquod phase, washing by using solvent, removing solvent, vacuum drying so as to obtain spherical catalyst. Said spherical catalyst uses spherical MgCl2-alcohol-organic complexing agent as carrier, and the preparation process of said catalyst is retatively simple, and small in environmental pollution. Said invention can effectively regulate grain size of catalyst ...
