杨树绒毛，此外

f poplar fluff, also known as thistle fluff, is actually the method of dispersing its seeds. Although many people believe it's pollen and causes allergies, it's not actually poplar pollen, but a light structure that carries its seeds. These thistle fluff floats in the air like snowflakes and can accumulate in large quantities in parks and streets. They also have an important characteristic: they are highly flammable, which can increase the risk of fires in dry areas.
