Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of seed germination experiment, more particularly to a culture dish cover capable of being used repeatedly. BACKGROUND

[0002] In the seed culture process, the culture dish with the dish cover is often used to cultivate the seeds, wherein the dish cover needs to have certain air permeability to ensure that the inside of the culture dish and the outside air can be properly exchanged, and also needs to have certain blocking effect on the external bacteria to enable the seeds to grow smoothly. Most of the existing culture dishes have air holes on the cover body, and then air permeable cotton is used to cover the cover to make the cover have air permeability. However, in the process of air permeation, the gas contains certain water vapor, which will cause the air permeable cotton to absorb the water vapor. However, the air permeable cotton is adhered to the air hole by adhesive, and after absorbing the water vapor, the adhesive fails, and the air permeable cotton is easy to fall off, so that the dish cover only has the air permeability function and cannot block the bacteria.
