Description

Technical Field

[0001] This utility model belongs to the field of microbial inoculant technology, specifically relating to a microbial inoculant mixing device. Background Technology

[0002] The effects of microbial inoculants include increasing crop yield and improving crop quality. The effective bacteria in microbial inoculants can secrete active substances such as gibberellins, cytokinins, and auxins, which stimulate, regulate, and promote crop growth and development, thereby increasing yield and improving quality.

[0003] Microbial inoculants are prepared for industrial and agricultural purposes. Industrial preparation generally involves a strict step-by-step cultivation process, with large production volumes and rigorous procedures. It uses shake flasks, seed tanks, and fermentation tanks for step-by-step cultivation. This large-scale and rigorous process is used to produce standardized commercial microbial inoculants. However, for agricultural use, it is necessary to expand the microbial inoculant through cultivation. When preparing the expansion materials, a cultivation tank and stirring rod are required. The inoculant (such as EM bacteria, lactic acid bacteria, etc.), carbon source (such as brown sugar or molasses), nitrogen source (such as wheat bran, soybean flour, and peanut bran), and water are added to the cultivation tank in a certain proportion and stirred. After mixing, the tank is sealed and fermented. Some inoculants require daily stirring and oxygenation during fermentation.

[0004] Agricultural propagation buckets are generally just simple plastic buckets with lids, and the stirring rods are just ordinary wooden sticks. Before mixing, it is only necessary to rinse the propagation bucket and stirring rod with boiling water for disinfection before use. Although the propagation cost will be greatly reduced, the current agricultural propagation buckets require opening the lid for stirring, and the environment in which the propagation buckets are placed is not sterile. Dust and bacteria in the air can easily enter the propagation bucket, affecting the quality of the bacterial agent propagation. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a microbial agent preparation device that solves the problem that current agricultural preparation expansion tanks require opening the lid for stirring, and the environment in which the expansion tanks are placed is not sterile, allowing dust and bacteria in the air to easily enter the expansion tanks and affect the quality of the agent preparation.
