The utility model discloses a grid culture dish for counting the number of ensiling microorganism colonies. The cell culture dish comprises a cell culture dish body, a sealing plate is hinged to the top of the grid culture dish body, a fixing block is fixedly installed on the front surface of the grid culture dish body, a storage cavity is formed in the grid culture dish body, a suction cup is fixedly installed at the bottom of the grid culture dish body, and a handle is fixedly installed on the outer side wall of the grid culture dish body. Through the sealing plate, on one hand, the storagecavity can be shielded; on the other hand, the leakage phenomenon of the culture medium inside can be prevented; the sealing performance of the grid culture dish body is improved; the stability between the grid-dividing culture dish body and the contact surface can be improved through the suction cups, the sliding phenomenon of the grid-dividing culture dish body is prevented, the practical performance of the grid-dividing culture dish body is improved, a user can conveniently and accurately control the thickness of a culture medium in the storage cavity through the scale lines, and the experiment accuracy is improved.
