The invention discloses a fiber-reinforced high-strength corrugated paperboard and a production method thereof. The fiber-reinforced high-strength corrugated paperboard comprises an inner paperboard layer and an outer paperboard layer; and a second fiber composite layer, a first fiber composite layer and a third fiber composite layer are sequentially arranged from top to bottom from the inner paperboard layer to the outer paperboard layer, and an adsorption layer is arranged on the face, away from the second fiber composite layer, of the inner paperboard layer. Double protection is achieved through multi-layer composite superposition of the first fiber composite layer and the second fiber composite layer, the overall strength of the corrugated paperboard is greatly improved, the heat insulation effect is achieved through the third fiber composite layer, peculiar smells of objects stored in a corrugated paperboard box can be adsorbed through the adsorption layer, and the overall practicability of the corrugate
