The invention discloses a compression-resistant flame-retardant carton, and particularly relates to the technical field of carton processing. The compression-resistant flame-retardant carton comprises the following raw materials: bamboo pulp, wood pulp, modified straw fibers, modified coconut fibers, a flame retardant, modified diatomite and an auxiliary agent. The straw fibers have good mechanical properties, the straw fibers are pretreated through alkali treatment, active points on the surfaces of the straw fibers can be increased, the dispersity of fiber particles can be improved, then the straw fibers are subjected to graft modification, the mechanical properties of the straw fibers can be improved, the sodium silicate, the carboxy nitrile rubber and the grafted straw fibers are subjected to blending modification, so that the flame retardant property of the straw fibers can be effectively improved; and the coconut fibers are treated by the silane coupling agent and the nano magnesium oxide and then are bl
