What is the effect of the various colors of lacquer painted on the northern trees in winter?

The role of lacquer painted on northern trees of various colors is to kill bacteria, insects, etc. As follows:

The so-called white lacquer is not white lacquer, but a certain percentage of quicklime.

They can have different formulations.

The role of lacquer is as follows.

Sterilization and insecticide, lime has a certain bactericidal and insecticidal effect, which can kill some overwintering fungi, bacteria and pests parasitic on the trunk

Prevent pests in the soil from climbing up the tree trunk. Because pests generally prefer black places but not white ones, and the trunks are painted whiteLime waterPests in the soil cannot climb trees along the trunk.

Due to the small temperature difference between day and night, the trunk is not easy to crack, and the temperature is very low in winter nights。When it is exposed to sunlight during the day, the temperature rises, which makes the trunk prone to freezing and cracking. After applying lime water, because lime is white, 40 to 70 percent of the sunlight can be reflected.

Precautions in the use of lime water.

1.When calfing lime water, metal containers should not be used for containers such as crockpots, wooden barrels, or plastic drums.

3.Prepare the lime water you want to use

Yellow tape wrapped around trees in winter is a common type of tape. After packing, apply a layer of glue. There is no medicine in the glue and it will not cause harm to the human body.

The purpose is also to prevent pests. It is a non-polluting method of pest control. Some pests, such as spider mites.

Overwintering on soil and weeds. When a tree sprouts in the spring, it moves up through the tree and is firmly stuck when it passes through the tape. Yellow tape is yellow and will attract more pests.

In addition to the above two aspects, winter protection measures for trees include: timely watering of frozen water, that is, watering trees at the beginning of November, especially newly planted trees, which can not only replenish the water required by the trees themselves, but also improve the tree's conditionCold resistance；Plastic pruning can adjust the shape of the tree, coordinate the relationship between the aboveground and underground parts, promote flowering and fruiting, and eliminate pests; felling and digging up dead trees; Removing weeds and leaves, removing weeds and leaves in green spaces for centralized treatment, not only eliminates pests and diseases, but also eliminates fire hazards.

It is for sterilization, insect prevention, heat preservation, and that is not lacquer, it is lime liquid made of some other materials added by lime, the temperature difference between morning and evening in the north in winter is large, lime liquid can not only sterilize but also kill the parasite eggs on the trunk to protect the tree, and it can also reflect the sunlight, keep the tree warm so that it will not be frozen to death in the winter with a particularly large temperature difference.

It is generally painted with white lacquer and is composed of quicklime, water, oil and stone sulfur mixture. It mainly has the functions of warmth, insecticide and sterilization. Of course, it is also beautiful to paint it in white.

The effect of painting the tree with various lacquers is actually to keep the tree warm, because the temperature in the north is particularly low in winter.

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.

In winter, the trunk is painted white, which can reduce the damage caused by the large temperature difference between day and night on the sunny side of the tree, and the white lime is like a piece of clothing, which plays a role in keeping warm, can prevent frostbite of trees, and can eliminate pests and diseases that overwinter in the cracks of the bark, and prevent pests from climbing along the trunk and damaging the trees.

Street trees should be whitened with a special garden whitening agent, that is, a mixture of lime and stone sulfur, which can kill the eggs in the bark and the pests and diseases in the soil, prevent the trees from being burned in summer, and at the same time look neat and tidy.

Why do trees paint them white in winter, it turns out that these are the reasons why.

It is not white paint that is applied to the trunk in winter.

This kind of white is generally called lime water, and it is generally made of water, quicklime and salt as the main raw materials. It is mainly applied to the trunk of the trunk to kill insects, insects and freeze damage.

Prepare for spring with an insect-proof 、、、

The white stuff is the painted lime water.

There are three main ways people help trees survive the winter: tying straw ropes, brushing lime water, and covering them with plastic film. The main benefit of these three methods for trees is to keep them warm in winter.

Brush the big tree with lime water, just like wearing a thin cotton jacket for the big tree, it is also warm, and wearing this cotton jacket, can you not grow insects Every winter, many underground insects will climb to the tree to find a small tree hole to make a nest and eat the bark, so it is especially suitable for large trees that are easy to grow insects.

Painted not paint, but white lime water.

On the one hand, it can prevent insects and sterilize.

On the one hand, it is winter, and 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. Hope to adopt.

Not lacquer, lime, warmth, insect proof.

Why do trees apply whitening agent in winter? We know that winter weather is cold, and if we spend a while in an air-conditioned house and suddenly go outside, you will feel very cold outside. If you've been outside, the feeling of cold isn't as strong as it was when you first came out.

Many people get frostbite on their hands and feet, mostly because of washing warm hands and feet with cold water, or washing cold hands and feet with hot water, or baking cold hands and feet on fire. If we rub our hands and feet vigorously before taking hot water, and rub our hands and feet with a little hot water to make them gradually warmer; Before the fire, gradually get closer to the fire from far to near; Especially when taking cold water, first rub with a little cold water to let the hands and feet slowly become cold and cold, so that the ** of our hands and feet can greatly reduce and avoid the formation of chilblains after the process of gradual adaptation from cold to hot or from hot to cold. 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.

Why can plant whitening prevent cold damage, frost damage, and pests and diseases? Because the weather is cold in winter, however, when the sun comes out during the day, plants are not as comfortable as people are 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.

In winter, the trunk of the roadside tree is whitened with lime mortar for two purposes. After whitening with lime mortar, the sunlight can be reflected off can reduce the temperature difference between day and night of the trunk, reduce the frost damage of the tree, and the young trees that are not cold-tolerant, also. The trunk needs to be wrapped with straw to enhance its ability to withstand cold.

The second is to prevent insect pests, in the lime slurry to add the corresponding liquid, in addition to the lime slurry itself also has an insecticidal effect, which can effectively prevent pests.

Hello, the white paint painted by the tree is called the white liquid painted by the tree, the formula is similar, the main ingredient is lime and some other fungicides or protective agents.

The role on the road is:

1. Protect the trunk and prevent frostbite.

2. Control and control of pests and diseases at the base of the stem.

3. White has a reflective effect, which can be seen clearly at night and is not easy to bump into, so as to avoid trees being harmed 4.

It is not recommended to paint white in the park, which will affect the viewing effect.

This kind of "paint" is a temporary self-made insecticide and fungicide made by garden workers, boiling with water, quicklime, sulfur powder, salt, clay and a little grease and other materials according to a certain ratio and process. Before winter, gardeners apply the agent to a section of tree trunk 1 meter high from the ground, which is called "whitening". Whitening is an important part of winter greening maintenance and management, which plays a variety of roles in protecting trees

First of all, as the weather gets colder, many pests on the tree climb down the trunk to the ground to find a suitable environment to escape the cold, and the whitened part of the trunk is itself an important place to hide pests, eggs and pathogens. When the flowers bloom in the following spring, these pests return to the trees to damage the trees, and the pathogens breed and infect the trees. Whitening is an effective means of controlling the weak links of disease and insect transmission, which can significantly reduce the occurrence of pests and diseases in the next year.

Secondly, in the sunny day of winter, the sunny side of the trunk and large branches is exposed to direct sunlight, and the temperature rises, so that the somatic cells of the tree are active, and the temperature drops rapidly at night, so that the bark tissue has no time to adapt to the frost damage, and the so-called "sunburn" phenomenon occurs. In particular, trees with thick trunks, dark colors, and poor tissue toughness are more susceptible to frost. The whitened trunk can reflect 40 70 sunlight and reduce the temperature difference between day and night of the trunk, thereby preventing the occurrence of frost damage.

In addition, whitening can also give the trees a white and neat aesthetic.

It is coated with a whitening agent for the trunk, such as the whitening agent for the big trees of the happy forest, which can not only play a role in keeping warm in winter and preventing sunburn, but also has a good killing effect on the germs and insect eggs in the cracks of the bark, and at the same time plays a beautiful and neat function

This is the trunk painted white.

The trunk of the tree is painted white to prevent pests and diseases, delay the budding of the tree, and avoid sunburn damage. In continental climates with drastic changes in sunshine and temperature, whitening can reduce the absorption of solar radiation heat by the aboveground parts of trees, thereby delaying the bud germination period. Whitening will reflect sunlight and avoid local increase in moisture in the branches, thus effectively preventing sunburn hazards.

The willow tree is painted white immediately after planting, which can also prevent dry pests.

The common formula of whitening agent is: 10 parts of water, 3 parts of quicklime, a small part of stone sulfur mixture, table salt, and oil (animal and vegetable oil). When preparing, the lime should be dissolved first, the grease should be poured in, stirred fully, and then water should be added to mix into lime milk, and finally stone sulfur mixture and brine can be added.

In addition, in order to extend the whitening period, an adhesive can be added to the mixture.
