1. Drop leaves (deciduous tree species, start to drop leaves in autumn to reduce consumption) 2. Strengthen the water absorption ability of the roots and bury the roots deep in the soil 3. Reduce their own activities. Reduce your own internal activities, growth and expansion to reduce internal consumption and put yourself in a state of hibernation 4. Move flowers and plants that cannot be wintered outdoors or woody flowers into indoor or solar greenhouses 5. Flower-like shrubs that cannot be moved indoors can leave 20-30 cm of the above-ground part and cut off the rest and then accompany the soil or cover with weeds 6. Arbors can be put on the trunk with straw ropes or wrapped with straw 7.

When winter came, people all wore thick clothes, gloves, scarves and hats, but when we looked at the trees, they were bare, except for the pines and cypresses, which were still full of leaves and green. When the cold wind blows, the branches seem to be shivering, are they afraid of the cold? Can they withstand the cold of winter?
For many years, people have been secretly raising the profile of trees for the winter, with some of the earliest ideas suggesting that trees, like warm-blooded animals, may produce heat on their own. Another theory is that trees have less water content in winter, so they are less likely to freeze and die even below freezing. But we know that trees themselves do not produce heat, and willow branches and needles that freeze below zero degrees Celsius do not die because they freeze.
So, what is the secret? In order to cope with the severe cold of winter, the trees have adopted a "sleep" method. We know that trees consume nutrients to grow, and in spring and summer, trees grow fast, consume nutrients quickly, and have weak frost resistance.
In autumn, when the daytime temperature is high, the sunshine is strong, and the photosynthesis of leaves is also strong, while the temperature at night is low, the trees grow slowly, consume less nutrients, and accumulate more, so the trees grow more and more "fat", and the ability to resist the cold is also getting stronger and stronger. In winter, when the temperature is lower, the growth of trees is in a state of stagnation, and they enter "hibernation", at which time the nutrients stored in the body also become sugar and even fat, which are cold-proof substances that can protect the trees from freezing. Whether trees can enter the "sleep" is directly related to whether it can survive the winter, the deeper the "sleep" is, the more frost-resistant, on the contrary, those trees that can not enter the "sleep" state are easy to be frostbitten or frozen to death, which requires us humans to help them, to put on "clothes" or build a "house".

Trees can survive the winter on their own, that is, some trees lose their leaves in winter, but they naturally grow in spring, and the trees can withstand the cold and heat throughout the year.
-
There are some trees of southern varieties that do not survive the winter in the north, and some northern varieties. There is no need to care that he will survive the winter, if it is a southern variety, he should use some thick, warm ones, and do not wrap him or move him indoors.

Broadleaf trees retain water in their bodies through their broadleaves, allowing them to safely overwinter. Evergreen trees have cuticles on the surface of their leaves, which can reduce excessive water loss.
-
When the tree is wintering, it can be covered with a protective film, or it can be whitewashed, so that it can survive the winter.
-
How do trees survive the winter, and some trees spend the winter by no longer growing new leaves, no longer ** nutrients, stop growing, and wait until the next spring when the weather is warm and grown.
-
How do trees survive the winter, trees will be in a state of hibernation when they see winter, so he doesn't know the outside world is cold.
-
If the tree survives the winter, first the leaves will wither, and then the people's words will apply that lime to the trunk.
-
How to survive the winter Actually, he is the same person as us Sun Wu In the winter, he will drop all the leaves, which is to protect the branches.
-
Animals have their own way of spending the winter, so how do trees survive the winter?

Trees are very adaptable when it comes to wintering, and they can cope with sudden drops in temperatures and cold weather conditions in a variety of ways. In some areas with harsh growing environments or low temperatures, trees need to understand and master some adaptation measures to survive the cold season.
Generally speaking, the strategy for wintering trees is to prepare for a cold spell in the fall. First of all, trees need to shed their leaves as much as possible to reduce water loss, and defoliation also prevents branches from cracking due to water swelling. Secondly, the trees also need to adjust their material metabolism and enter a dormant state of cleansing, so as not to exhaust their physical strength and be unable to survive in the severe cold.
In addition, trees in some cold regions can form thick ice coats to protect the tree body during the winter months.
Further, there are some other coping strategies for trees. For example, some of the lower tree species will seek heat from the soil and extend their roots deeper into the soil for a warmer environment. There are also tree species that wind and form small valleys to protect them from wind and snow, thus maintaining good temperatures.
In addition, some species form a fine capillary-like system on the surface of the bark to better retain water and heat.
In short, the wintering strategies of trees are diverse, and their ability to adapt to the environment is very strong. Due to the differences in environmental factors, different tree species have different winter coping strategies, which need to be dealt with in their respective environments. <>

During the summer vacation, I read an article called Yu Shu ((How Trees Survive the Winter)). The main point of this article is that in the Soviet Union, if the winter was particularly cold and there was little snow, a lot of trees would freeze to death, most of which were small trees. Fortunately, the trees have a way to keep the cold from penetrating deep into their bodies, otherwise all the trees would have died.
The best protection for trees is soft snow cover. Everyone knows that careful gardeners deliberately bend the little fruit trees that are afraid of the cold to the ground and bury them with snow, so that no matter how cruel the winter is, it will not freeze to death "us" "the northern forest!"
I used to train all year round for the swim team, but the scariest thing was winter. As long as I get out of the water, my whole body hair mouth opens, and when I see the water, I have goosebumps all over my body, and when I was looking at the water in a daze, suddenly my mother came over and said Treasure Come on, you are the strongest, as long as you go into the water and stay in the water for a long time, it is often not cold. After listening to my mother's words of encouragement, I thought that I was the strongest, and I would definitely be able to do it.
My lips were shaking all the time when I swam ashore, probably because I was getting used to it underwater, and suddenly it was cold when I went ashore. Since then, I am not afraid of winter travel.
Finally, I would like to say that as long as you are strong, you will be able to do it.

As early as autumn, due to the high temperature and abundant sunlight during the day, the photosynthesis of the leaves of the trees is vigorous, so that many nutrients are produced, and at night the temperature is low, the trees grow slowly, so the nutrients produced by the trees consume less and accumulate more, and begin to store nutrients for the winter. At this time of winter, the starch accumulated in the autumn is converted into sugar, and some into fat. Sugar and fat protect cells from freezing to death.
If it is a whole tree, the branches and foliage on the south side are relatively thick, and if it is a large tree that grows relatively long, the growth rings are denser in the direction of the south. In addition, depending on the local climate, such as what kind of wind is often blowing, trees tend to fall in opposite directions.
Trees can breathe by transpiring and losing water. Plants with aerial roots can use aerial roots to aid respiration. Mainly respiratory. The main organ of respiration is the leaf. >>>More

After planting, mulberry seedlings often fail to germinate normally, or grow poorly after germination, and eventually die. Especially in the dry areas of winter and spring, the survival rate is low, and if the lack of plants is serious, it will affect the normal yield of mulberry orchards. To improve the survival rate of mulberry planting, attention should be paid to the following tasks. >>>More
