Description

Technical Field

[0001] This utility model relates to the field of microbial experimental equipment technology, and in particular to a biocontrol plate confrontation experimental culture dish with precise positioning scale. Background Technology

[0002] The plate confrontation experiment involves inoculating two potentially inhibitory bacterial strains into a petri dish and observing their inhibitory effect after co-culturing for a certain period. In plant protection biocontrol experiments, the plate confrontation experiment requires calculating the inhibition zone, inhibition rate, and antagonism index. By setting precise positioning scales on the surface of the petri dish, researchers can more accurately determine the location of microbial inoculation, observe the colony growth range, and interaction areas. This provides a foundation for accurate recording and analysis of experimental data, and is of great significance to the accuracy and scientific rigor of biocontrol research.

[0003] Traditional petri dishes lack positioning markers, requiring lab technicians to manually mark inoculation points, leading to errors in the contact distance. Furthermore, the positioning scales on common petri dishes are relatively rigid. When measuring the range of microbial colonies, the scales are fixed to the petri dish and cannot be adjusted, resulting in subjective boundary determination and insufficient measurement accuracy during precise positioning and scale measurement. During the observation of microbial growth, researchers find it difficult to accurately determine the boundaries and growth range of colonies using these scales, leading to significant measurement errors. Additionally, petri dishes require special customization, lack adaptability to common applications, and are inconvenient to assemble and disassemble, resulting in poor usability. Therefore, we propose a biocontrol plate contact plate with precise positioning scales to solve these problems. Utility Model Content
