AI Technical Summary
The filter paper in existing seed culture dishes poses risks such as poor air circulation, cross-contamination of mold between seeds, seed displacement and microbial contamination due to opening the lid for water replenishment, which affect the reliability of experimental results.
Design a filter paper for installation in a seed culture dish, including a filter paper layer, a support layer and an absorbent layer. The filter paper layer has rectangular grooves arranged at equal intervals. The bottom surface is fixed with a support layer composed of absorbent cotton columns made of degreased cotton. The absorbent layer is made of pure cellulose fiber material to ensure air circulation and seed fixation.
It improves the operational efficiency of seed germination experiments, reduces manpower consumption for water replenishment, prevents cross-contamination by mold, ensures fixed seed position, reduces the risk of microbial contamination, and maintains the reliability of experimental results.
