We study the properties of the Bose-Hubbard model for the triangular superlattices. Firstly we give an easy experimental suggestion to produce a triangular supperlattice system. Then we use the generalized effective potential Landau theory to investigate the quantum phase diagram of the system. Our research provide reference data for the future study of the triangular superlattice system.
