[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By arranging a magnetic convex edge on the outer side of the first culture dish, the second culture dish and the third culture dish, and arranging an adsorption magnet at the bottom of the first culture dish, the second culture dish and the third culture dish, the first culture dish, the second culture dish and the third culture dish can be easily stacked by the magnetic convex edge and the adsorption magnet. When not in use, the first culture dish, the second culture dish and the third culture dish are stacked together to avoid the first culture dish, the second culture dish and the third culture dish being randomly placed and lost when not in use;

[0014] 2. By setting a partition plate, when installing the partition plate, the installation ring is sleeved on the protruding rod, and the partition plate divides the internal space of the first culture dish into four positions of the same space, which is convenient for culturing and testing different foods in the same culture dish.
