Abstract: The invention relates to a method for producing paper, paperboard, and cardboard having high dry strength, by adding (a) at least one trivalent cation in form of a salt; (b) at least one water-soluble cationic polymer; and (c) at least one water-soluble amphoteric polymer to the paper pulp, dehydrating the paper pulp while forming sheets, and subsequent drying of the paper product, wherein the water-soluble cationic polymer (b) is selected from the group of polymers containing vinylamine units (i), and from polymers containing ethylenimine units.
