[0005] A culture dish for Pleurotus geesteranus spawn comprises a dish bottom, a holding ring, a dish cover and supporting feet, wherein the holding ring is arranged on the outer wall of the dish bottom, the dish cover covers the opening of the dish bottom, the bottom surface of the dish cover is flush with the top surface of the holding ring, the supporting feet are evenly fixed on the bottom of the holding ring, and the shells of the dish bottom and the dish cover are light-shielding shells.
[0006] Furthermore, the top wall of the dish cover is a transparent top wall, and a light shielding sheet is installed on the transparent top wall.
[0007] Furthermore, an L-shaped limiting groove is arranged at the edge of the transparent top wall, a limiting block is arranged at the outer edge of the shading sheet and is clamped and installed in the limiting groove, and a handle is arranged on the shading sheet.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] The present application is provided with a holding ring. After the dish cover is covered on the opening of the dish bottom, the bottom surface of the dish cover is flush with the top surface of the holding ring, thereby improving the sealing of the dish cover and solving the problem that there is a gap between the dish bottom and the side wall of the dish cover of the traditional culture dish, which requires secondary use of plastic film for sealing. Support feet are provided at the bottom of the holding ring, so that there are ventilation gaps between the culture dishes when the culture dishes are stacked in the incubator, and the temperature of the top, bottom and middle of the culture dishes is uniform. The shells of the dish bottom and the dish cover are light-shielding shells, which ensure that the mycelium is not easily affected by ambient light during the inspection of the incubator.

[0017] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.
[0018] The utility model discloses a culture dish for Pleurotus geesteranus strains, Figure 1-5 A culture dish for Pleurotus geesteranus spawn comprises a dish bottom 1, a holding ring 2, a dish cover 3 and supporting legs 4. The holding ring 2 is arranged on the outer wall of the dish bottom 1, the dish cover 3 covers the opening of the dish bottom 1, the bottom surface of the dish cover 3 is flush with the top surface of the holding ring 2, the supporting legs 4 are evenly fixed on the bottom of the holding ring 2, and the shells of the dish bottom 1 and the dish cover 3 are light-shielding shells.
[0019] The culture medium for inoculating the strains of Pleurotus geesteranus can be placed in the dish bottom 1, and the holding ring 2 is convenient for taking the culture dish and opening the dish cover 3, thereby preventing the traditional culture dish from slipping easily when being taken and opened. At the same time, after the dish cover 3 is covered on the dish bottom 1, not only the dish cover 3 is sealed with the side wall of the dish bottom 1, but the bottom of the dish cover 3 is in contact with the holding ring 2 to achieve a sealing effect, thereby avoiding the problem that the traditional culture dish only relies on the dish cover 3 to cover the dish bottom 1, and miscellaneous bacteria are easy to contaminate the culture dish from the bottom through the gap between the dish bottom 1 and the side wall of the dish cover 3. When the culture dishes are stacked and placed in the incubator, the support legs 4 at the bottom of the holding ring 2 are placed on the holding ring 2 below in sequence, so that each culture dish has a ventilation interval to ensure uniform temperature control. At the same time, the support legs 4 are arranged below the holding ring 2, so that the dish bottom 1 is equivalent to being suspended, which is conducive to uniform temperature control of the dish bottom 1 and good growth of the mycelium. The shells of the dish bottom 1 and the dish cover 3 are light-shielding shells, which are not easy to affect the internal mycelium when the incubator is taken out for inspection.
[0020] See also Figure 1-5 The top wall of the dish cover 3 is a transparent top wall 31, and a shading sheet 5 is installed on the transparent top wall 31. After removing the shading sheet 5, the mycelium growth can be checked through the transparent top wall 31, which is convenient for checking the mycelium growth without opening the dish cover 3, and at the same time can reduce the influence of external light on the mycelium when taking out the incubator.
[0021] See also Figure 1-5 The edge of the transparent top wall 31 is provided with an L-shaped limiting groove 32, and the outer edge of the shading sheet 5 is provided with a limiting block 51 which is clamped and installed with the limiting groove 32. The shading sheet 5 is provided with a handle 52. The handle 52 and the limiting groove 32 not only facilitate the removal of the shading sheet 5 to observe the inside of the culture dish, but also facilitate the removal of the dish cover 3.
[0022] Working process:
[0023] After the bottom 1 and cover 3 of the dish filled with culture medium are disinfected, they are inoculated on a clean bench, and the mushroom strains are inoculated in the culture medium of the bottom 1 of the dish. Then, the cover 3 is closed so that the bottom surface of the cover 3 is in contact with the top surface of the holding ring 2. The holding ring 2 is taken to move the inoculated culture dish to the incubator, and the legs 4 of the culture dishes are placed one by one on the holding ring 2 of the culture dish below to stack them. Then, the incubator is closed and cultured for a certain period of time. The culture dishes are taken out regularly to check the growth of mycelium. When checking, the culture dish is taken out by the holding ring 2, and the shading sheet 5 is rotated by the handle 52 to move the limit block 51 out of the limit groove 32 to remove the shading sheet 5, and the mycelium growth is observed through the transparent top wall 31. Then, the shading sheet 5 is installed and returned to the incubator.
[0024] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
