The latest location of fruit trees prone to frostbite in winter

Cold winter is often a difficult season for fruit trees, some freezing disasters will be more concentrated. And fruit trees are most prone to frostbite, so which positions of fruit trees are more likely to be frostbitten? Let's get to know it.

1. Branches

Branches have always been the location where fruit trees are more vulnerable to frostbite, because the branches of fruit trees are relatively thin, low resistance to low temperature, coupled with a wide range of distribution, the area of cold air is the most extensive when cold air strikes. Branches are also the worst place to keep out the cold, so in the face of the cold air in winter, growers can remove some weak branches in advance to reduce the nutrient consumption of trees and maximize the use of nutrients.

2. Backbone

The freeze disaster on the trunk of fruit trees is generally due to the fact that trees with thin bark are easy to appear, mainly because the nutrient transport pipes of the bark are frozen, resulting in nutrients can not be supplied to the tree, resulting in freezing to death. Such as pear trees, peach trees and other fruit trees are more prone to this situation, because its trunk is not strong, can not effectively protect against the cold, generally need foreign matter to protect against the cold. It is common to add a coat to the trunk, that is, using straws and the like to keep out the cold.

3. Tree root

The root damage is the most serious, first, it is not easy to find, second, it is not convenient to treat. It is mainly due to frostbite caused by excessive temperature difference in winter. snow water covers the surface layer when it is cold, then the temperature increases and melts into the soil, and then frostbite the roots with the decrease of temperature. Therefore, in winter, attention should be paid to the waterproofing of the roots, and it is best to open a drainage trough around the roots, which can effectively prevent freezing.

4. Tree neck

The tree neck, which is a part of the soil, is one of the most vulnerable to freezing damage in daily life, and it is also one of the most important cold protection points when it is cold-proof. Every day, we see that there are white powdery substances in this part of some fruit trees, and those use rain to keep out the cold. This is the junction of soil, air and water vapor. Microbes are very active and are most vulnerable to cold air in winter, so this is the first place to keep out the cold.

These are some of the positions where fruit trees are prone to frostbite. On the other hand, as long as it is not frostbite, fruit trees basically do not need to keep out the cold, and some fruit trees can resist pure snow. If it is rain and snow, you should pay attention to keep out the cold, it is more easy to frostbite fruit trees.
