Culture device for strain propagation

The utility model discloses a culture device for strain propagation, which belongs to the technical field of strain culture and comprises a constant-temperature culture box, a tray is slidably connected to an inner cavity of the constant-temperature culture box, a pull groove is formed in the surface of the tray, and a culture tray is fixedly connected to the top of the tray. A deodorization box is fixedly mounted on one side of the constant-temperature incubator; according to the constant-temperature incubator, the air exhaust assembly and the air inlet groove are used in cooperation, the air exhaust assembly can exhaust air in the constant-temperature incubator, and external air enters the constant-temperature incubator through the air inlet groove, so that the air circulation effect in the constant-temperature incubator is improved, and the situation that hyphae grow slowly due to insufficient ventilation is prevented; according to the constant-temperature incubator, a deodorization box is arranged, a deod
