In the winter, many people will put lime on the trees, does this do any good?

Mosquitoes generally prefer dark, damp, dark and dirty places, and mosquitoes are not easy to grow after plastering trees with lime. Because lime is white, and lime has a certain bactericidal and insecticidal effect. Therefore, applying lime in winter can protect the tree from mosquitoes.

It can help the saplings not to freeze to death in winter, because the lime will heat up, so it will have a certain warmth effect, and in some colder places, it will also wrap the tree in clothes.

There are many roles. First, lime has a certain bactericidal and insecticidal effect, which can kill some fungi and pests parasitic on the trunk. Secondly, coated with lime can also play a certain role in heat preservation.

The trunk is less likely to crack when there is a large temperature difference between day and night. Third, prevent some pests from climbing up the tree trunk.

In winter, many people will plaster the tree with lime in order to add a protective layer to the tree, and the lime-filled trees can not only obtain a certain temperature in winter, but also effectively prevent insect pests.

Trees are insulated and frost-proof. Prevent trees from freezing to death in the winter and still sprout and grow normally in the spring.

By doing this, you can keep the trees warm in the winter so that they don't freeze to death.

Brushing trees with lime in winter is mainly for heat preservation and anti-freezing, sterilization and disinfection, as well as the prevention of insect pests

1. Sterilization and disinfection: Trees can play a role in sterilization and disinfection, usually in early winter to the trees with white ash, after the winter cooling, the germs will hide in the cracks of the trees, and so on in the spring of the next year, after the temperature rises, the germs begin to move, and begin to harm the trees. If you brush white ash in winter, dilute it with lime core pants powder with water and apply it to the skin of the tree, so that the germs can be killed and sterilized and disinfected.

Second, thermal insulation and anti-freeze rent: to the tree brush white ash can also play the role of thermal insulation and anti-freezing, the temperature in winter is relatively low, usually around 10 during the day, if the bark is dark, it will absorb light and heat, so that the modification of Jane will improve the heat in the tree, and so on at night will cool down, the temperature is generally below 10, or even below 0, so that the branches of the tree are cracked due to the large temperature difference, and are easy to freeze. Brushing white ash absorbs less heat during the day, and even if it cools down at night, the temperature difference between day and night is not too large, thus protecting the trees and promoting safe wintering.

3. Pest control: Brushing trees with white ash can also prevent and control pests. White ash is toxic to various insect pests, and after brushing, it can reduce the chance of insect infestation, virtually protect trees, and also avoid animal bites.

When applying, it is usually applied from the base of the tree upwards, about to a meter height.

1. Sterilization and insecticide. The main component of lime is calcium oxide, which has a certain bactericidal and insecticidal effect, and those who like to parasitize on the trunk of fungi, bacteria and pests. The lime also prevents the various longhorn beetles from creaking in the cracks of the bark, preventing the possibility of the group making a comeback in the small world the next year.

The sulfur pat of the whitening agent has a special odor, and it also has the effect of killing insects, mites and bacteria. The two are strong together, and Shibang helps trees to complete the cause of sterilization and insecticide.

2. Anti-freezing. Relying on the characteristics of their own color – white objects are highly reflective.

The main chemical component of lime water is calcium hydroxide, which will absorb carbon dioxide in the air to form a white calcium carbonate precipitate that is insoluble in water, and the reaction formula is as follows: Ca(OH)2 + CO2 = CaCO3, which will cover the surface of the bark to play a role in heat preservation, reduce the loss of water and heat, and prevent cracking and damage of the bark; In addition, lime water is more alkaline, and it also has a certain sterilization and disinfection effect, which can inhibit the damage of harmful microorganisms such as fungi or other small insects to trees.

What is the substance and what role does the whitening of the trunk in winter do.

The thing used to paint the lower part of the trunk white is called whitening agent, and the main ingredient of whitening agent is lime milk, as well as salt, soybean flour, and stone sulfur mixture. There are two main purposes for applying whitening agent to plants in winter: on the one hand, to prevent cold and frost, and on the other hand, to prevent pests and diseases.

Lime has an antibacterial and anti-virus effect, of course, to prevent pests and diseases.
