Why do you want to wrap a straw rope around the tree in winter?

Lead: With trees, the world becomes greener. In winter, we often find that the trees on the main road are wrapped with ropes. So, today Xiaobian tells friends, why do you want to wrap ropes around trees in winter? Why do you want to wrap a straw rope around the tree in winter? Next, Xiaobian will take you to learn, and increase the rhythm of knowledge. Don't hurry to watch.

Why do you want to tie ropes around trees in winter

1. Tie hemp ropes to keep the trees warm.

Plants also have a body temperature, but the body temperature of plants is related to the outside world. Plants can adjust their own temperature through stomata on leaves, for example, opening stomata to reduce body weight by transpiration, and closing stomata to reduce transpiration when the body temperature is too low.

However, plants have different temperature adjustment abilities. Some plants are cold-resistant and others are heat-resistant. For example, winding a tree with hemp rope in winter is equivalent to adding a layer of clothes to the tree and keeping it warm.

2. Keeping water

In fact, it has the same effect as keeping warm. When it is cold, it can also lock the transpiration of plants, especially in winter, plants absorb little water, so it is necessary to help trees reduce water loss.

3. Pest control

In winter, many kinds of insects need to lay eggs and spend the winter, and most of them choose to lay eggs or pupate on plants.

If you tie a hemp rope, the insects will feel that the hemp rope is softer than the trunk, and then they will choose to pupate in the hemp rope for the winter, which will protect the trees from insect pests.

After the winter, the eggs and pupae can be eliminated by replacing the hemp rope.

4. Prevent people and animals from damaging

Putting a layer of clothes on trees can also prevent people and animals from damaging them. For example, cats and dogs like to catch trees, and some people will damage them. This protective layer can at least prevent some injuries.

5. Stabilize and fix trees

Tying hemp rope can fix the trend of trunk to a certain extent, especially for new saplings, which can resist a certain degree of wind and rain swing and prevent trunk damage and bark wear.

How do trees spend the winter

Wear white boots

Whitening the trunk: The trees we see wear "white boots", that is, the greening workers brush the trees with a layer of whitening agent, the main components of which are quicklime, sulfur mixture, salt and grease. Do you know the function of these "white boots"?

1

Beautify the environment

Wear uniform white boots for trees and add a beautiful scenery to the city in winter.

2

Prevention of freezing injury

Because the whitening agent can reflect part of sunlight and reduce the absorption of radiant heat by trees, it can reduce the temperature difference between day and night at the base of the trunk and avoid sunburn caused by freezing injury and alternating freezing and thawing.

3

Reducing pests and diseases

The mixture of lime, salt and sulfur in the whitening agent has the function of sterilization and disinfection, which can eliminate some overwintering germs and eggs in bark cracks and reduce the source of overwintering pests and diseases.

Wear winter clothes

Cold-proof dressing: For some plants with poor tolerance to low temperature, greening workers will put on a thick layer of winter clothes for them to prevent freezing injury in case of cold wave. Winter clothes are made of straw and insulation film, which can prevent wind and frost, reduce water loss and protect trees from winter.

wear a belt

Tie grass rope (grass target): Some garden pests will find a place that can shelter from the wind and rain for the winter. Greening workers will tie grass rope or grass target in the middle of the trunk to lure pests to spend the winter. Destroy the grass rope or grass target together with the wintering pests before next spring, which can effectively reduce the harm of some pests.

adhesive tape (adhesive tape): for some pests who have the habit of going up and down trees for the winter, greening workers apply adhesive tape or stick adhesive tape in the middle of the trunk to prevent pests from going up and down trees.

Scraping off the cracked bark

Some garden pests like to hide under the cracked bark or cracked bark for wintering. Greening workers can effectively reduce the survival rate of wintering pests by scraping off the cracked bark and destroying the wintering sites of pests.

clearing away the diseased plants

Many plant pathogenic microorganisms or pests will overwinter with the diseased branches, diseased leaves, diseased flowers, diseased fruits and other plant diseased plants of the host plants. Cleaning up the diseased plants in winter and centrally destroying them can effectively reduce the source of overwintering diseases and pests and reduce the overwintering base of diseases and pests.

mending tree holes

after the xylem of trees decays and hollows for various reasons, tree holes will be formed, which will weaken the tree vigor, aggravate the aging of trees, reduce the firmness and load capacity of branches, and saprophytic insects will easily breed inside the tree holes, which will affect the health of trees. In winter, when trees are dormant, the tree vigor can be improved by mending tree holes, which can reduce pests and diseases and reduce potential safety hazards.
