What are some ways for trees to survive the winter safely?

Most trees shed their leaves in winter, but they won't freeze to death, but it's best to take some precautions against the cold. Don't clean up the leaves that it falls, just sweep it to its roots and pile them up. If it is a slightly less cold-tolerant variety, you can also wrap the trunk with weeds to keep it warm, in fact, most trees do not have to worry about wintering and will not freeze to death.

1. Wrap the tree with thermal insulation belt, 2 spray wet antifreeze cream, 3 spray the trunk white, 4 pour the frozen water, 5 high pei.

Pruning branches and leaves, pruning diseased branches and excess branches can reduce nutrient loss and help trees survive wintering; Trees are painted white, and the trees can play a role in heat preservation and effective anti-freezing after being coated with whitening agent; Mulching and mulching, wearing a wet straw coat after mulching the trees, can reduce water loss, and can also resist cold and frost; Chemical agents to supplement trees with trace elements.

Improve the stress resistance of trees and reduce the damage caused by frost damage.

Pruning branches such as diseased branches, wounded branches, and overlapping branches can effectively reduce nutrient loss, store nutrients in the roots, and reduce canopy closure.

The branches and leaves can improve the ventilation environment and increase the light area, which can effectively help trees overwinter.

The most common anti-freeze method when whitening trees is to use quicklime.

The ratio of sulfur powder: salt: water = :20 is equipped with whitening agent, which can be used to keep the trunk and the parts with weak cold resistance, which can play a role in heat preservation and prevent and control diseases and insects.

Mulching trees with wet straw coats can effectively ensure the water loss of trees in winter, and can also reduce the frost damage caused by advection cooling and radiation cooling, which can prevent cold and frost, and is an ideal way to overwinter.

Spray trees with amino acids before and after frost damage.

Foliar fertilizers such as peptides, and timely supplementation of trace elements, can effectively improve the stress resistance of trees, and paclobutrazol can also be sprayed.

Chemical agents such as fluthramine inhibit the growth of late autumn buds, which can significantly reduce the damage caused by frost damage.

1. Whitening method: In winter, the branches of the trees are painted white with quicklime and stone sulfur mixture, which can help prevent insects and frost.

2. Wrapping method: covering the upper periphery and above the trees with a layer of film, or wrapping the trees with straw, can play the role of windproof and anti-freeze residue. If the tree is very tall, you can build a greenhouse around it to prevent it from freezing.

3. Irrigation of frozen water: In areas where the soil is easy to freeze in winter, before the land is frozen, fill enough water once, which is called "frozen water". The time of pouring frozen water should not be too early, otherwise it will affect the cold resistance.

Generally, it is advisable to irrigate during the period of "daily and night freezing", so that after the freezing, a permafrost layer will be formed around the roots of the trembling tree to maintain a relatively stable temperature and not cause damage to the plants due to sudden changes in the external temperature.

To keep the trees warm in winter, you can use the whitening method, which requires the use of quicklime and sulfur powder to prepare a whitening agent, and then use the whitening agent to paint the trunk of the tree white to avoid the bark being frozen and cracked, or use straw rope to wrap the trunk of the tree to keep it warm and cold, so that the plant can survive the winter smoothly.

1. Whitening method

When breeding trees in winter, you can use the method of whitening to keep warm, you need to use quicklime and sulfur powder to boil water into whitening agent, and then apply whitening agent to the trunk of the tree to avoid excessive temperature difference between day and night in winter, and make the bark of the plant dry and cracked, and at the same time can prevent pests from burrowing into the bark to lay eggs and hibernate.

2. Bandaging method

If you want the trees to survive the winter smoothly, you can use straw rope or plastic film to wrap the trunk of the plant in the middle of November every year to prevent wind and frost and make the plant grow healthily, or you can build a plastic greenhouse around the tree to keep the environment around the plant above 0 degrees, so as not to freeze to death.

3. Fertilization management

When maintaining trees in winter, it is necessary to apply a hot fertilizer to the plant before winter, you can use nitrogen, phosphorus and potassium compound fertilizer or well-rotted organic fertilizer to improve the cold resistance of the tree and promote its vigorous growth, or water the tree with a frozen water to make the temperature in the soil constant.

4. Maintenance method

When maintaining trees in winter, it is necessary to use sharp and sterilized scissors to cut the branches and leaves that are too dense to improve the light transmission and ventilation between the trees, while reducing the loss of nutrients, and to spray diluted disinfectant on the fractures of the tree branches to prevent them from rotting.

<> the way for the tree to spend the winter is dormant, after the tree enters the dormant state, the leaves will all fall off, and the demand for water is small, at this time it can be carried out every 10-15 days, and apply organic fertilizer to the plant once a month, provide sufficient fertilizer and water for the tree, which is conducive to the tree to better survive the winter.

1. Dormancy. <>

The way for the big tree to spend the winter is dormant, because the temperature is very low in winter, the plant will directly enter the dormant state, so as to achieve the effect of resisting the cold, the leaves of the tree will all fall off in winter, and these leaves can be used to enclose the roots of the plant to protect against the cold.

2. Provide moisture.

After the tree enters dormancy, the need for water is less, and the plant can be watered every 10-15 days to keep the soil moist, so that the tree can absorb enough water and avoid the lack of water in the plant.

3. Lighting conditions.

When cultivating large trees, it is best to place them in a place where the sun is full of pure energy, because the plant has a great demand for light in the process of growing fibrous bonds, and the big tree can only grow healthily if it absorbs sufficient light.

4. Provide nutrients.

During the growth period of large trees, you can apply organic fertilizer to the plants every other month, and it is best to apply fertilizer to the soil when fertilizing, and then water it once to dilute the fertilizer in the soil, which is conducive to better absorption of nutrients by the big tree.

1. The method of keeping trees warm in winter includes bandaging method and Shensheng painting method, which is to use straw, wheat straw and plastic film and other materials to bandage the trees, and after wrapping, it can avoid frostbite of the plants.

2. The painting method is to paint the trees with old white paint, which has the effect of keeping warm, and can also kill bacteria and prevent pests and diseases. Smaller seedlings, during the winter months, can be bagged for cold protection.
