Causes of dead cherry trees and control measures

Cherry is very popular in the market in recent years, and the market benefit is good, so its development is also very rapid, the cultivation area and yield are constantly increasing, but the phenomenon of dead cherry trees is becoming more and more serious, affecting the development of cherry industry. So what are the reasons for the dead cherry tree? I don't know what to do Let's take a look.

1. Waterlogged dead trees

It is mainly caused by anoxia and asphyxia in the roots after stagnant water, which often occurs in orchards with rainy, poor drainage and poor soil viscosity and permeability. It shows that the tree is weak, the leaves are small and thin, and there are often symptoms of element deficiency, most of the roots will blacken and die, the lenticels in the root neck are dilated and suffocated, and in serious cases, the edges of the leaves are scorched yellow, similar to drug damage.

Solution: the orchard should choose loose loam, pay attention to ploughing and loosening soil in the process of symptoms, increase soil permeability, and pay attention to drainage and loosening soil in rainy season to avoid stagnant water retting.

2. Freeze-damaged trees

The freezing injury will occur when the big cherry lasts for a long time in the low temperature environment, such as the plant germinates and blossoms later, the leaf is small and shows the symptom of iron deficiency, the root becomes light brown after freezing, and the serious branches freeze to death or the branches become thick and swollen and easy to flow glue.

Solution: pay attention to heat preservation in the low temperature season, pour frozen water before overwintering, so that the roots are not frozen, the tree trunk can be bound and painted white to resist the low temperature, and can also be smoked in the orchard, and if possible, the greenhouse can survive the winter.

3. Fertilizer kills trees

When applying farm manure again, it is concentrated near the main root, or the concentration of fertilizer is too high, which may make the xylem of the main root black and necrotic, and the small root and whisker root turn reddish brown and die. In recent years, rotting roots and dead trees often occur in big cherry orchards due to the application of immature farm manure or improper fertilization.

Solution: fertilizer must be paid attention to, first of all, it is not suitable to directly contact the root system, so as not to burn roots, and then the application of farm manure must go through full ripening and fermentation, only in this way can there be no fertilizer damage.

4. Diseases and insect pests kill trees

Diseases and insect pests are one of the main causes of dead cherry trees, resulting in more diseases and insect pests, such as root rot, root cancer, white silk disease and other root diseases, which will cause dry branches to die; and branch diseases such as neck rot, wood rot, rot, rough skin disease, glue disease and other branch diseases will also lead to tree weakness and death.

Solution: for the prevention and control of diseases and insect pests must not be taken lightly, from the cherry seedlings to start prevention and control, in each stage to take different control methods to strangle diseases and insect pests in the cradle.

The above is the introduction of the causes and control measures of dead cherry trees. I hope I can help you. If you want to know more about it, please follow us.
