Description

Technical Field

[0002] Soil microorganisms are a general term for all tiny organisms in the soil that are invisible or unclear to the naked eye. Strictly speaking, they should include bacteria, archaea, fungi, viruses, protozoa and microscopic algae. Their individuals are tiny, generally calculated in microns or millimeter, and there are usually hundreds of millions to tens of billions of them in one gram of soil. Their types and numbers vary with the soil-forming environment and the depth of the soil layer. They carry out oxidation, nitrification, ammoniation, nitrogen fixation, sulfidation and other processes in the soil, promoting the decomposition of soil organic matter and the transformation of nutrients.

The soil sample screening device for soil microorganism detection is arranged by the coordination of the first motor, the first transmission rod, the first main rolling roller, the rotating rod and the first auxiliary rolling roller. When in use, the first motor's external power supply drives the first transmission rod and the first main rolling roller to rotate, and then the first main rolling roller drives the first auxiliary rolling roller to rotate, and then the soil sample for microorganism detection that needs to be screened is poured onto the surface of the first main rolling roller and the first auxiliary rolling roller for rolling, thereby playing the role of initial crushing of the soil sample for microorganism detection;
