The invention relates to a rolling method of a high-toughness magnesium-based composite material ultrathin plate, which comprises the following steps of: selecting a rolling process at 300-400 DEG C due to the fact that a plurality of passes are adopted in the temperature range, the rolling direction of the next pass is vertical to the rolling direction of the previous pass, the pressing amount of each pass is 10%, and the composite material plate is subjected to heat preservation for 5 minutes at the temperature of 300-400 DEG C after each pass of rolling; in the deformation process of the magnesium-based composite material, basal plane slippage and non-basal plane slippage are started at the same time, deformation can be better coordinated, and the structure is more uniform. The high-toughness magnesium-based composite ultrathin plate provided by the invention is obtained by the preparation method, and the performance of the plate is better. When the rolling method is used for nano-particle reinforced AZ91
