as well as a certain wind speed
are conducive to the scattering of flying flotsam
It was the first to start floating in North China
Poplar, for example
When the average daily temperature is greater than 0°C

Reaching this standard, poplar began to fly
More than 10 days later
The catkins will also enter the drifting period
Willow trees are highly adaptable in northern regions
Alkali-resistant, drought-resistant, easy to survive, and fast timbering
The greening time is long
North China and Huanghuai are widely planted
However, willow trees are dioecious
Fly floc is the seed of the female plant
Spring is the time when females reproduce their offspring
The bulbs on the inflorescence burst when ripe
Cotton wool-like wadding is exposed
Reproduction is done with the help of wind propagation
The location is presented
The sight of "snowfall".
