Objective To establish a method for sampling and examining plant pollen. Methods Pollen on the clothes was collected by adhering to conducting resin, and pollen in soil was collected by adhering to conducting resin after soaking in organic solution and diluted acid. Microstructure of pollen was analyzed by SEM. Results Different kinds of plant pollen can be identified according to the shape, size, surface pattern and aperture of pollen, and five kinds of mountain soils can be distinguished according to different kinds of plant pollen contained in soils.Conclusion Methodestablished is accurate, reliable, and effective in sampling and examining plant pollen and distinguishing soils.
