After frost damage occurs, branches are vulnerable to pathogenic bacteria. What are the effective prevention and control measures for fruit tree frost?

Cold is a fatal blow to fruit trees. In severe cases, fruit farmers will lose no profit. Is there an effective way to prevent late spring cold? When it comes to preventing natural disasters, human beings are very insignificant. People have proposed many preventive methods. Enhancing tree vigor is the basis for preventing frost. We need to do this from many aspects such as fertilizer and water management, pest control, and pruning. Here we focus on Let’s talk about the issue of fertilizer and water management. This is also where many fruit farmers are prone to problems.

Damage to yield and quality: The most intuitive harm brought to us by the late spring cold is reduced production, no harvests, and reduced quality. When fruit trees are blooming and setting fruits in early spring, once they encounter late spring cold, they will suffer from reduced yields and severe losses, which will affect their fruit flowers, flowers, and fruits. Fatal damage is caused to young fruits, and the quality of the flower buds is also different due to the different positions of the flower buds. After frost damage occurs, some flowers bloom late, and high-quality flowers will be preserved from frost damage, especially the tops and axillary buds of short branches. Since they open later, they usually freeze more lightly, so this part of the bud should be fully utilized.

Freeze damage caused by spring cold and frost mainly affects the branches of above-ground fruit trees, while the root system of fruit trees underground is still in good condition. As long as appropriate measures are taken, new branches can sprout from the fruit tree and the crown of the fruit tree can be restored. It can effectively reduce frost damage to fruit trees. 2. Smoking to prevent frost. Based on the experience of fruit trees suffering from frost damage over the years, you should pay attention to the weather forecast before and after fruit trees bloom, especially at night. When the temperature drops to the critical temperature for fruit trees to freeze, start smoking. Generally, firewood with larger smoke and slightly dampness is used as raw material.

Spraying Tianda 2116 on the flowers and leaves of fruit trees one to two days before the arrival of the cold wave can reduce the damage to the fruits and stamens. If more cigarettes can be lit in the orchard when the cold wave comes, it can effectively reduce the frost damage. It is difficult to treat after freezing, so it is best to take precautions in advance. Water before the frost, smoke, spray water in the early morning, and spray brassinolide and amino acid fertilizers a few days in advance to enhance frost resistance.
