Description

Technical Field

[0001] The utility model belongs to the technical field of fungus cultivation, in particular to a high-efficiency cultivation device for arbuscular mycorrhizal fungi monospores. Background Art

[0002] Arbuscular mycorrhizal fungi (AMF) are an important beneficial soil microorganism that can establish a symbiotic relationship with more than 80% of terrestrial plants. After establishing a symbiotic relationship, the hyphal network of AM fungi extends into the soil, greatly increasing the surface area of ​​the absorbing roots, improving the plant's acquisition of soil nutrients, enhancing the plant's tolerance to surrounding environmental stress, and promoting plant growth.

[0003] At present, the common method for isolating AMF strains is to select single spores from the soil, then inoculate the spores onto the plant roots, and cultivate them together in a seedling tray or flower pot filled with a sterilized culture matrix (such as soil or fine sand) for 2-3 months, in the hope that the spore inoculation is successful and the spores are reproduced. This planting method of seedling trays or flower pots usually has a very low success rate. On the one hand, the roots of adjacent planting holes are easily entangled with each other through the bottom drainage holes, resulting in cross-contamination of hyphae produced by different spores, and the goal of single spore separation cannot be strictly achieved. On the other hand, either the root growth space of the seedling tray is too small to produce spores, or the scattered roots in the flower pot are not conducive to AMF infection. For this reason, we proposed an efficient culture device for single spores of arbuscular mycorrhizal fungi. Utility Model Content

The protrusion and the recess can be matched and plugged in, and the bottom isolation disk can be rotated by pushing the protrusion on the outside of the belt.
