The invention discloses a seeding mold for growing silicon crystals by using an orientated solidification method and a crystal growing method. The seeding mold is arranged at the internal bottom of a quartz crucible and comprises a seed crystal container and a sealing liquid container, wherein the sealing liquid container consists of cavities connected to the periphery of the seed crystal container and is used for accommodating a sealing substance; and the seed crystal container is provided with a first cavity for accommodating seed crystals. A method for growing monocrystalline silicon/similar monocrystalline silicon by adopting the seeding mold comprises the following steps of: arranging or setting the seeding mold at the bottom of the quartz crucible; arranging the sealing substance and the seed crystals in the sealing liquid container and the seed crystal container respectively; putting a silicon raw material into the quartz crucible; and growing monocrystals/similar monocrystals by adopting orientated solidification. By adopting the seeding mold and the crystal growing method, the problem of placement of the seed crystals can be solved without changing the structures of the conventional orientated solidification and quartz crucible, dislocation of the seed crystals in the seeding process is eliminated, and the spontaneous nucleation phenomenon of melt from the bottom wallface of the crucible is avoided. The seeding mold has low cost and is easy to process.
