Catkins are flying all over the sky. How flammable is catkin?

What's it like to snow in succession? The difference between salting and air can be simulated, but what if catkins are not because of the wind? Although the artistic conception of catkins depicted in this poem is beautiful, the north has completely turned into a catkin world since spring, and netizens have complained that this is all caused by catkins, which not only harms people's health and causes allergies, but also easily leads to fires. Everyone simply loves and hates this catkin, which is white and light, and floats away as soon as it blows. It is difficult to grasp and clean up, and it is also very troublesome.

Catkin comes from the north of China, which falls into catkin after Tomb-Sweeping Day every year, while the south is invaded by buttonwood. Beautiful spring also makes people feel anxious and will last for more than a month. Pervasiveness can also make people allergic and painful. In fact, these white flying flocs are the seeds of willow trees. They were not disturbed by catkins in northern China in the 1950s and 1960s, because at that time, the northern spring would be shrouded in sandstorms. In order to control sandstorms, we tried to plant various trees in the north of China to prevent sandstorms, but these trees are prone to diseases and insect pests, so we finally decided to plant willows. The environment in northern China is harsh, but willows are more likely to be like a duck to water and do not attract pests. Therefore, willows are planted in a large area in northern China, which has advantages and disadvantages. Since then, the northern part of China has never been invaded by catkins in spring.

Catkin is flammable and harmful. Catkin is a willow seed covered with a layer of fluff, and the seed is rich in oil, which is also the reason why catkin is flammable. Catkin is very light, as long as there is airflow, it will be everywhere and gather in every corner, such as weeds growing from the middle and roadside parking places. At this time, as long as there is a little open flame, it will instantly become a sea of fire. In addition, the high temperature in spring and the dry air brought by the spring breeze will cause huge property losses in case of fire. For example, in April of 20 17, Beijing Fire Corps received a fire alarm of 30 1, and in April of 20 16, a forest near the south gate of a university in Shandong High-tech Zone caught fire. The cause of the fire is that there are too many fallen leaves in the forest, and a large number of catkins are piled together. The catkins burn instantly because of the slow ignition speed, which eventually leads to the burning of 200 meters of greening. For example, there are many such incidents.

Prevent the harm caused by catkins. Catkin not only affects normal people's travel, but also is prone to fire accidents. Therefore, friends must take precautions when they go out in the spring catkin season. In addition, because of the flammability of catkins, don't burn catkins with an open flame when you see them. Don't throw cigarette butts around to prevent sparks from igniting catkins during factory operation. Wear a mask when going out to prevent catkins from flying into your mouth. Sprinkle water on the ground to fix catkins so that they don't float around, and clean them up in time to avoid the danger of catkins accumulating in a large area.
