Why is the tree painted white and not completely painted? Why should trees be painted white

First of all, to know the tree's"Painted white"What pests and diseases is it to prevent? Pest infestations are mainly for prevention"Drillworm"The borer will burrow into the tree from the lower part of the tree, usually at a distance of thirty or forty centimeters from the ground!

When the heartworm burrows into the tree, it will cause irreparable damage to the tree, and it will multiply more and more, and spread quickly, it turns out that many trees in our street have been drilled!

There are also some scale insects.

They will also hide in the dirt under the tree for the winter, so brushing these chemicals on the lower part of the tree can effectively prevent these pests!

Of course, whitening the tree also kills bacteria and viruses.

Anti-freeze, beautiful and so on!

The range of whitening of the trunk is from the ground to the area of 1 meter high of the main trunk, focusing on whitening the root neck of the trunk, focusing on the white of large trees with incomplete crowns, diseased trees, and the trunk facing south, and the bifurcation of the main branch also needs to be carefully painted. Limestone has a certain effect on new branches, and it can achieve good results by applying rice, and most ordinary people can paint it without the help of ladders, which is also beautiful.

Whitening trees can kill bacteria, insects, frost resistance, etc.

The whitening on the trunk is lime water containing sulfur powder, the main component is calcium oxide, which has a certain bactericidal and insecticidal effect, and those who like to parasitize on the trunk fungi, bacteria and pests are its dishes. Lime also prevents longhorn beetles from laying eggs in cracks in the bark. The sulfur of the whitening agent has a special odor, and it also has the effect of killing insects, mites and bacteria.

The two have joined forces to help trees complete the cause of sterilization and insecticide.

The white part of the trunk can reflect 40% to 70% of the sunlight back, absorbing much less sunlight than before, and the temperature difference between day and night of the trunk will not be so large, so it can effectively prevent frostbite and frost cracking.

1. Reduce the harm of pests and diseases. The whitening agent contains a certain amount of insecticide and fungicide, so the whitening agent can kill some overwintering fungi, bacteria and pests parasitic on the trunk of the tree, and the white color has a tendency to avoid some pests. From the point of view of pest habits, they generally like black, dirty places, not white, clean places, after brushing whitening agent, these small insects will not climb up the tree again, so as to reduce the number of pests and diseases on the tree in the next spring.

2. Improve the frost resistance of trees. Due to the relatively high daytime temperature in winter, the temperature is low at night, and the bark of many trees is dark and easy to absorb heat, causing the liquid flow in the tree body, and the temperature begins to freeze after the temperature drops at night, and so on and so forth, the bark of many trees will crack in spring, affecting the appearance and reducing the tree momentum, causing the tree to die when it is serious. After brushing with whitening agent, a large part of the sunlight will be reflected during the day, reducing the temperature difference between day and night of the tree trunk and reducing the frost damage of the tree.

3. Increase the degree of aesthetics.

4. Increase the safety of driving at night, because white has a good reflective effect at night, so it can make pedestrians and vehicles at night see the road more clearly, reducing certain safety hazards.

"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.) of stinging and chewing mouthparts, 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.

The specific reasons why the tree is painted with white lacquer are as follows:

1. Pest control. The tree is coated with a white coat to protect against insect pests. Generally, the trees on both sides of the sidewalk will be coated with a layer of white paint, and the paint contains some insect repellent substances, which can be applied to the root of the tree to prevent reptile pests from crawling from the soil to the trunk, thereby eating the shoots and leaves growing on the trees, affecting the growth of the plant.

2. Anti-frostbite. Applying a layer of white to the tree can also prevent frostbite on the tree. Generally, the white paint is applied in winter, and the skin of the tree can breathe, which is easy to sell frostbite, but after applying the white dantong paint, the roots of the plant seem to be covered with a protective film, so that the plant is protected from frostbite.

3. Eye-catching reflection. Applying a layer of white paint to the tree can also prevent some traffic accidents. Because white is a more eye-catching color, it can be seen clearly in the daytime, and when the white is closed at night, there will be a reflective phenomenon after the illumination of the headlights, so that it can provide a tree in front of the driver, so as to avoid the vehicle directly hitting it.

4. Neat and good-looking. Applying a layer of white paint to a tree also has a neat and beautiful use. There are many kinds of trees planted on both sides of the sidewalk, so the color and texture of the bark are also different, and the trunk is painted with a layer of white paint, which is more neat and beautiful, just like a student wearing a school uniform.

<>There are four reasons for the trees on both sides of the general sidewalk to be coated with a layer of white paint, one is to prevent reptile pests from invading the plants, the second is to prevent frostbite on the roots of the plants in winter, the third is to prevent traffic accidents, white can be reflected under the illumination of the light, and the fourth is neat and good-looking, the trees next to the general sidewalk have ornamental value, and they are painted white more neatly and beautifully.

1. Pest control.

The tree is coated with a white coat to protect against insect pests. Generally, the trees on both sides of the sidewalk will be coated with a layer of white paint, and the paint contains some insect repellent substances, which can be applied to the root of the tree to prevent reptile pests from crawling from the soil to the trunk, thereby eating the shoots and leaves growing on the trees, affecting the growth of the plant.

2. Anti-frostbite.

Applying a layer of white to the tree can also prevent frostbite on the tree. Generally, the white paint is applied in winter, and the skin of the tree can breathe, which is easy to die of frostbite, but after the white paint is applied, the roots of the plant seem to be covered with a protective film, so that the plant is protected from frostbite.

3. Eye-catching reflection.

Applying a layer of white paint to the tree can also prevent some traffic accidents. Because white is a more eye-catching color, it can be seen clearly during the day, and at the same time, white will be reflected at night after the illumination of the headlights, so that the driver can be provided with a tree in front of him, so as to avoid the vehicle directly hitting it.

4. Neat and good-looking.

Applying a layer of white paint to a tree also has a neat and beautiful use. There are many kinds of silly trees planted on both sides of the sidewalk, so the color and texture of the bark are also different, and the appearance is more messy, and the trunk is painted with a layer of white paint, just like a student wearing a school uniform, which is more neat and beautiful.

It can improve the survival rate of trees. Whitening of the trunk refers to the trunk being artificially brushed or sprayed with a white "protective film".

The main ingredient of the whitening agent is lime milk, as well as salt, soybean flour, stone sulfur mixture, and the plant is painted with whitening agent in winter, which has two main purposes:

On the one hand, cold and frost prevention, on the other hand, pest prevention, winter day and night temperature difference is large, after the plant is whitewashed, white can reflect the sunlight and various radiation during the day, to avoid the temperature in the plant body is too high, greatly weakening the temperature difference between day and night, to avoid the plant from being hurt by sudden temperature change, in addition to the autumn and early winter, many insects like to lay eggs in the cracks of the old bark, Guo Dong bleach Dun many pests have to kill the left and right trees, painted white will reflect the light, pedestrians and drivers at night can see the road more clearly.

It is not white paint, the scientific name is whitening agent, lime water mixed with copper sulfate.

First, it can protect the trees from insects, so the height of the coating is only as high as the pests can climb. Second, it is convenient to walk at night, after the trees and telephone poles are painted white, they will reflect the light, and pedestrians at night can see the road more clearly. Third, anti-freezing, after whitening with lime mortar, the sunlight can be reflected, which can reduce the temperature difference between day and night of the trunk and reduce the frost damage of trees.

Why should the spine be painted with white paint under the tree:

1. Pest control.

Avoid reptilian pests that climb up the tree along the branches of the cherry blossom and pose a threat to the plant.

2. Anti-frostbite.

The whitening agent has a warming effect and insulates the trunk from the cold air outside.

3. Accident prevention:

White can be reflected under the illumination of the light, avoiding traffic accidents.

4. Aesthetics:

The trees on the sidewalks are ornamental, and they are more beautiful when painted white.

Precautions for painting white paint on large trees:

1. Before brushing white:

1. The best brushing period for whitening agent is autumn and before winter; After a new tree is planted. When brushing, you should choose a sunny day, and the temperature in winter should not be lower than 0.

2. Before using tree whitening agent to whiten the tree, the tree should be pruned in winter, and then the cut branches should be gathered and burned, and the injured parts such as cracks and freeze cracks on the trunk should be wrapped with plastic film.

3. Observe whether the trunk has been eaten by pests, if pests are eaten, the pests should be killed with cotton or cotton cloth soaked in medicine, and then whitened with tree whitening agent.

4. When using tree whitening agent, according to the roughness of the bark, the trunk whitening height will be different.

5. Before using tree whitening agent, the dead skin, warped skin and dirt of the tree should be removed before use, and it should not be mixed with other agents. Please keep the tree dry before painting. <>

Reasons why large trees should be painted with white paint: insect pests, frostbite, and accidents.

1. Pest control.

Applying white paint to trees can prevent pests, and usually trees on both sides of the pavement are also painted with white paint because white paint can repel insect repellent substances. Applying it directly to the trunk of the tree can prevent some reptile pests from crawling into the trunk of the tree from the soil, eating the thick buds and leaves of the tree, affecting the growth of the tree.

2. Anti-frostbite.

Painting the tree white is also to prevent the tree from freezing to death, because the surface of the bark tree also breathes, and it is easy to freeze to death in winter, so you can apply white paint as warmth, but after applying white paint, the roots of the plant are like a protective film, which can prevent the plant from freezing to death.

3. Accident prevention:

Applying a layer of white paint to the tree can also prevent some traffic accidents, mainly because white is a striking color, which can be seen very clearly even during the day, and at the same time, white will also reflect light when illuminated by car lights at night, which can provide drivers with trees in front of them to avoid vehicle accidents.

Precautions for applying whitening agent for trees

In order to make the best effect of whitening trees, the whitening agent should be used with the mixture and should not be left for a long time. When using, the whitening agent is fully stirred to facilitate brushing, and the concentration of the whitening agent should be applied to the trunk without being downstreamed, not pimple, not warped after drying, and not falling off. When whitening, it must be even, especially in the bark gaps, holes, branches, etc., to repeat the brushing to avoid missing the brush.

Before using the whitening agent, scrape off the bark and moss and other parasites on the bark, it is best to cut off the diseased branches, weak branches, aging branches and overly dense branches, wrap the cracked and frozen cracks with plastic film, and then apply the tree whitening agent. In addition, the height of whitening should be appropriate, and it is necessary to be cautious when mixing insecticides and fungicides.
