What is the white layer that trees on the road are often painted with, and what is the purpose?

When winter comes, we often see many workers painting the trunks of trees on both sides of the road with white coating. Many people may feel that this is just for the neatness and aesthetics of the sides of the road. In fact, this white coating is the lime we usually use to paint the walls, and the workers apply it to the trees, which will play an important role in protecting the trees.

Every winter, the trees on both sides of our roads go into a dormant period. At this time, workers will be mobilized to protect the trees. Applying this white lime coating to the trees is the greatest protection for dormant trees. Because of lime water.

With an insecticidal and sterilizing effect, the trunks of the trees next to the highway have this protective layer, and they are able to avoid insect attacks to the greatest extent. In this way, the trees on both sides of the road can survive the winter. It will not be until the next year that we will be able to see it flourish.

Winters in the north usually have very large temperature differences. Of course, the trunk is not affected by the same temperature during the day and at night. During the day, when the sun rises, the temperature rises, and the trunk absorbs the heat from the sun; At night, when the sun sets, the temperature plummets, and the temperature on the surface of the trunk drops immediately.

However, due to the large temperature difference between day and night, the trunk is easily affected and cracks. That's why the workers had to paint the trunks white in the sun. This is the only way to absorb less heat and minimize damage to the trunk.

At night, when people are driving, the white trunk of the tree can help people identify the road information. In this way, the drivers are driving safely.

It will also get higher with it. Of course, this will also make the trees look neater and make our city look better.

Trees on the highway are often painted with a white layer, and these white substances are actually lime. Warmth, sterilization and insecticide, etc. The white substance coated on the tree can play a good role in keeping warm, ensuring that the tree will not freeze to death in the cold winter; In addition, lime has the effect of sterilization and insecticide, which can ensure that the bacteria and insects on the trees are killed, so that the trees can grow and grow.

This thin layer of whitening agent can form an environment that is not conducive to the overwintering of pests, can directly kill the pests and eggs overwintering in the bark layer, prevent rot, dry rot, canker and other trunk bast diseases, and improve the disease resistance of trees.

This white is lime water. The specific function is that it can kill bacteria and insects, and can ensure the normal growth of trees.

Better protection of trees, from the influence of pests, very beautiful, so that the plant from damage, better growth.

Benefits of whitening: 1. It has an anti-freezing effect on newly planted trees. 2. Kill the overwintering eggs of pests and diseases.

3. Clean and beautiful. 4. Reduce the absorption of solar heat energy by the tree in early spring, reduce the speed of tree temperature increase, delay the germination of the tree for about 2-3 days, and avoid the harm of the tree in early spring. The use of white coating agent is generally between the beginning of October and the middle of November, and it cannot be delayed, and the temperature is too low to cause it to fall off.

"Happy Forest" whitening agent is a new type of anti-insect whitening agent that completely replaces quicklime and stone sulfur mixture, adopts and absorbs advanced production technology and formula at home and abroad, uses nanoparticles as the base material, especially adds insecticides and fungicides, and has a good control and avoidance effect on pests (such as scale insects, termites, beetles, aphids, mites, leafhoppers, leaf rollers, stinging moths, etc.), and has a good killing effect on bacteria, fungi and eggs in the cracks of bark. Compared with traditional homemade whitening agents, the advantages are obvious.

Clause.

1. Lime has a certain bactericidal and insecticidal effect, which can kill some overwintering fungi, bacteria and pests parasitic on the trunk. In winter, some pests on the trees will burrow into the ground for the winter, and in the fall, they will not be able to come down after being brushed with lime, and they will freeze to death in winter. Brush it again in the spring of the next year, and it will not be easy for the insects that hibernate underground to climb the tree to cause harm.

Because lime can dehydrate the bugs and die, they will all stay away. But flying pests are useless.

Clause. 2. In winter, the temperature is very low at night; During the day, the temperature rises when exposed to sunlight, and the trunk is black-brown and easily absorbs heat, and the temperature of the trunk rises rapidly. In this way, the trunk is easy to freeze and crack. Especially large trees, the trunk is thick, the color is dark, and the tissue toughness is relatively poor, so it is more likely to crack.

After applying lime water, because the lime is white, it can reflect 40 70 sunlight, so the temperature of the trunk is not much different during the day and night, and it is not easy to crack.

In order to make the lime not go up and down, the height of the white ash is unified, in order to look better and more eye-catching.

I feel that the trees are brown, not very obvious under the car lights at night, and the white reflection is very good to see ** is the edge of the road, if it is simply to prevent insects, why not paint all the trees white just paint the side of the road white. You see, now that there is a fence, the trees are not painted white.

Insect-proof, cold weather prevents pests from climbing onto trees and damaging trees.

It's called eye-catching (wood), hehe

It is smeared with a kind of lime, which can help the trees to prevent insects and cold, because lime is alkaline and has a bactericidal effect.

Its main material is lime water, because the trees on the road are often on the road, so people will apply lime water to keep the trees warm from the cold. Another reason is to kill insects.

Mainly lime water, the main function is to kill bacteria, and then it can help the trees themselves to get rid of some small insects and other pests, and can also purify the surrounding air.

The white one is lime. The reason why it is applied to the tree is because the lime can act as an insect repellent and can also make the tree more frost-resistant in winter.

This white is lacquer, mainly to prevent the insects below from climbing up and biting the tree, and later many places are used to painting white paint, which looks more neat and beautiful.

Because at night, when the lights are dim, the white reflection is the most powerful, which is white paint, just to remind passers-by and cars not to crash into it.

It is lime water, which is mainly insect repellent. Landscaping workers work hard and paint the trees with lime water every year.

The white coating on the trees is lime, which mainly acts as an insect repellent.

The "white paint" is called a whitening agent. Its main ingredients are lime milk, salt, soybean flour, and stone sulfur mixture. Plants are coated with whitening agent in winter, on the one hand, to prevent cold and frost damage, and on the other hand, to prevent pests and diseases.

Principle: Because the weather is cold in winter, however, when the sun comes out during the day, plants are not as comfortable as people basking in the sun. After we bask in the sun, we can hide in the bed at night when there is no sun, but no matter how cold the plants are, they are in the same place, so that the day is hot and the night is cold, and there are many differences between cold and heat, and the place where the plant suffers is more serious than our frostbite.

After whitewashing, the plant can reflect the sunlight and various light radiation during the day, and avoid the temperature in the plant in time to be too high, thereby weakening the temperature difference between day and night, and avoiding the damage of the plant from sudden temperature change. Moreover, the whitening agent has a thermal insulation effect, as if our hands and faces are covered with antifreeze as well as skin creams. In addition, in late autumn and early winter, many insects like to lay eggs in the cracks of old tree bark for the winter, and whitening the tree has a killing effect on many pests.

Trees are brushed with lime water, which has several benefits:

Clause. 1. Lime has a certain bactericidal and insecticidal effect.

Clause. Second, in winter, crack prevention.

Insect prevention, can also be used as a warning at night.
