What is the cause of dry cracking of fruit trees?

The bark of fruit trees often cracks, and even the wooden layer can be seen from the cracks, and liquid seeps out. This phenomenon often breeds pests or causes the wrinkled parts to rot. There are many reasons for bark cracking, so it is necessary to judge according to the cracking situation and remedy it in time to prevent the cracking from expanding and causing damage to fruit trees.

Causes and treatment methods of dry cracking of fruit trees

During the growth of fruit trees, the bark often cracks, and even the wooden layer can be seen from the cracks, with liquid oozing out.

This phenomenon often breeds pests, or leads to the decay of folds, which has a great impact on the growth of fruit trees and even leads to the death of trees.

There are many reasons for bark cracking, which need to be judged according to the cracking situation. And remedy it in time to prevent wrinkles from expanding and causing damage to fruit trees. There are generally three reasons for fruit tree bark cracking.

(1) Reasons for the growth of trees

Under the condition of sufficient water and fertilizer, the xylem of fruit trees grows too fast, and the growth of bark can't keep up with the growth of xylem, which leads to the xylem spreading the bark and cracking the bark. This situation is especially common for trees that grow vigorously.

② Environmental reasons

Fruit trees are exposed to the sun for a day in hot summer, and the bark will crack after sudden rain, especially in the sunrise direction.

This is mainly because of the high temperature in summer. After being heated by the sun, the bark suddenly shrinks when it is cold under the stimulation of rain, resulting in cracking of the bark.

Secondly, in places with alternating cold and hot in winter and large temperature difference, it will also cause tissue necrosis and bark cracking in parts such as branch cambium.

3, the cause of the disease

The "belly-breaking disease" of fruit trees, also known as "frozen cancer", mainly damages the bark of the trunk or main branch, and there are many reasons for freezing injury in winter.

Xylem can be seen in the cracks of bark, and liquid can also be seen oozing from the cracks. Long-term non-healing of cracks often leads to diseases such as skin rot and white rot.

Comprehensive prevention and control measures of bark cracking

The causes of bark cracking are mostly related to poor frost resistance in winter, especially in cold winter areas in northern China. It is necessary to strengthen the anti-freezing of fruit trees in winter, such as the common methods of anti-freezing of fruit trees in winter, such as pouring anti-freezing water before winter.

Coat the fruit trees with white paint or wrap them for cold protection, and seal the roots of the fruit trees for insulation. The second is to do a good job in the daily water and fertilizer management of fruit trees and enhance the resilience of fruit trees.
