Description

Technical Field

[0001] The utility model relates to the technical field of microbial agent cultivation, in particular to an agricultural microbial agent cultivation device. Background Art

[0002] Agricultural microbial agents are live bacterial preparations made from target microorganisms through industrial production and expansion. They can increase the supply of plant nutrients or promote plant growth, improve the quality of agricultural products and the agricultural ecological environment, and therefore play an important role in agricultural production. The current cultivation of agricultural microbial agents usually uses a constant temperature and humidity incubator to ensure the optimal temperature and humidity for the growth and reproduction of agricultural microorganisms.

[0003] A search revealed an existing patent (publication number: CN220183208U) that discloses a microbial inoculum cultivation device, belonging to the field of microbial inoculum cultivation technology. The device comprises a microbial inoculum cultivation chamber and a plurality of vertically arranged and evenly distributed grid plates. Adjustment slots corresponding to the grid plates are formed on the inner walls of both sides of the chamber. Adjustment blocks are slidably connected to the inner walls of the adjustment slots. The cross-sections of the adjustment blocks and the inner walls of the adjustment slots both form a T-shaped structure. When the present invention is in use, the grid plates can be pressed or lifted, causing the adjustment blocks to slide within the inner walls of the adjustment slots. This sliding movement of the adjustment blocks can change the position of the connecting plates, thereby changing the spacing between adjacent grid plates. Alternatively, the positioning plate can be directly separated from the positioning opening, allowing the connecting blocks to slide out through the inner walls of the connecting plates. Thus, the spacing between test tubes in the vertical plane can be changed, making it easier to take test tubes of different lengths.

[0004] However, the above scheme and the existing constant temperature and humidity incubator are not convenient for oscillating culture of bacterial strains. In the actual culture process, bacterial strains and nutrients are placed in the culture tubes, but they are placed in a static culture, which makes it impossible for the bacterial strains to evenly absorb the required nutrients, which is not conducive to the large-scale reproduction of microorganisms, resulting in inconvenience in their use.

[0005] In view of this, the utility model proposes an agricultural microbial agent cultivation device. Utility Model Content
