[0002] Agricultural microbial inoculants are biological agents that utilize beneficial microorganisms to promote plant growth, improve soil health, and enhance crop resistance. Agricultural microbial inoculants are one of the core products for the green development of modern agriculture. The expansion cultivation in the production of agricultural microbial inoculants is a key step to ensure the effectiveness and production efficiency of the inoculants.

[0003] A search revealed existing technology (publication number: CN222119234U) for an expansion cultivation device for agricultural microbial inoculant production, which includes: a working box, wherein the working box has a cultivation chamber inside, two sets of culture dishes are installed inside the cultivation chamber, and an air supply mechanism for supplying air to the two sets of culture dishes is also provided inside the cultivation chamber; a detachable sealing plate is installed on the top of the working box; and a material handling mechanism is located between the two sets of culture dishes and the cultivation chamber, and the material handling mechanism is used to separate the two sets of culture dishes from the cultivation chamber. The mechanism includes a frame installed between each group of petri dishes and a connecting rod connecting the two frames. Each set of frames is equipped with a limiting mechanism to restrict the movement of the frame between it and the culture chamber. One set of frames is connected to the working box by a driving mechanism to move the frame. However, the existing method of handling the petri dishes is inconvenient in practical use. If workers need to retrieve the lower petri dishes, they must first remove the upper ones, resulting in low efficiency. Therefore, designing a propagation device for agricultural microbial agent production is essential. Utility Model Content
