When the temperature reaches zero degrees, whether fruit trees can be transplanted or not depends on the region. For example, in the northwest and northeast, when the temperature drops below zero and the climate is cold, there is definitely no way to plant fruit trees.
If it is in the south, the temperature will not exceed below freezing, and it is still possible to transplant fruit trees.
After transplanting, the fruit trees can only be in the hibernation period, and when spring comes, they will slowly wake up and resume growth.
However, the best time to transplant fruit trees is in early spring, when the fruit tree seedlings are still germinated, and the survival rate of transplanting can reach 100%.
Secondly, it is also the best time to transplant fruit trees after the leaves have fallen in autumn.
Because, after the leaves fall in autumn, it is about to enter winter. Transplanted seedlings will only take root, but will not sprout and grow. After a winter, the beginning of spring, will it recover and grow. In this way, the transplanted fruit tree seedlings will not be subjected to the process of secondary recovery growth.
Therefore, the best time to transplant fruit tree seedlings is: early spring and late autumn.
At least that's how I choose the time slot for transplanting fruit trees in my hometown.

In winter, when the temperature drops below zero, transplanting cannot be done because the soil freezes due to low temperatures. Some fruit trees are frost-resistant after adulthood, but they are particularly afraid of frozen roots when transplanting, and once the roots are frozen, the fruit trees will be difficult to survive or have a very low survival rate after spring. You can choose to transplant fruit trees after spring, the time can not be too late, after the land thaws, the soil becomes soft and watery, and there will be no lower cold air invasion in a short time, and there is no ultra-low temperature, at this time you can also plant fruit trees.
When the land is frozen, it cannot be planted during this time, and the survival rate of forced planting will become very low, either a month before the freeze or after the land has thawed. There is also a certain difference between autumn planting and spring planting.
Autumn planting, although the temperature is relatively low, physiological activities are relatively slow, but it does not stop, the root system will slowly recover, the temperature under the soil is higher than the low temperature of the air, the root system slowly recovers, and can grow slowly, the second year on the growth is higher than the spring planting, because it is to sprout after growing roots, there is also a risk of frost damage. Spring planting first germinates and then grows roots, and the growth is slightly lower than that of autumn planting, but the advantages are also obvious, there is no risk of frost damage, and if there are dead seedlings, they can be found in time and replenished in time.

Yes, when the temperature drops below 0 degrees, the saplings will hibernate and transplant is possible.
-
0 degrees is not recorded at the rate of fire, and it is best to have such a high survival rate in the spring of the following year.

Introduction to the precautions for transplanting fruit tree seedlings and seedlings:
A look at the transplanting of eggplant fruits and vegetables should grasp the "cold tail and warm head", which can not only avoid frost damage, but also strive for early maturity. Transplanting seedlings should be carried out in the morning on a sunny day, and it is best to plant vegetables in protected areas while transplanting, and buckle the shed immediately after transplanting. If the weather is bad, even if the seedlings are robust, they should not be transplanted, so as not to affect the quality of planting.
Second, look at the ground Nightshade fruits and melons, fruits and vegetables should be transplanted when the soil is dry and wet, so as to facilitate the survival of seedlings. After transplanting, vegetable seedlings in the protected area should be covered with plastic film to keep warm and moisture. The day before transplanting seedlings, the seedbed or nutrient bowl should be watered thoroughly to facilitate the transplantation of seedlings with soil without hurting the roots.
Even if the seedlings are overage, it is necessary to ensure that the soil is properly wet and dry and planted.
3. Look at the seedlings Eggplant fruits and melon vegetables should be transplanted with strong seedlings. The seedlings are strong, which can not only resist low temperature, resist late frost, but also root early. Before transplanting, seedling refining measures should be taken, so that the seedlings can adapt to the new environment soon after transplanting.
Seedlings should be transplanted with soil, fertilizer, water and medicine to facilitate the healthy growth of seedlings. If the seedlings are weak, even if the soil is properly dry and wet, and the weather is good, it is not advisable to transplant and plant too early, because the seedlings have poor stress resistance after transplanting, resulting in a lack of seedlings and monopolizing the yield.
Absolute Zero Absolute zero represents a temperature at which all the molecules and atoms that make up matter cease to move. Motion refers to all spatial, mechanical, molecular, and vibrational motions, including some forms of electronic motion, but it does not include "zero-point motion" in the concept of quantum mechanics. This motion cannot be stopped unless the agglomeration system of the moving particles is dismantled. >>>More

Frost is formed by water vapor, how does water vapor condense into frost? The Southern Song Dynasty poet Lu Benzhong wrote in "Southern Gezi Lusi": "The post invades the oblique moon, and the river bridge spends the evening frost. >>>More
Near-zero degrees are easy to affect the wires and deteriorate.
In physics, the Kelvin temperature was introduced for the convenience of research, and "absolute zero" was used as the starting point of the Kelvin temperature. Nowadays, people can easily get millions of degrees of heat, but they can't reduce the minimum temperature to absolute zero. For this reason, in thermochemistry, there is such a law: >>>More
