The causes and control measures of the latest peach trees

The striping of fruit trees is a common phenomenon, which will not only cause disordered shape, incomplete crown, delayed fruit, but also dry up and die of fruit trees. And peach trees are no exception, it is also very easy to strip in spring, so what is the cause of peach trees? How to prevent and cure it? Let's get to know it with the editor.

1. The influence of adverse factors

Generally speaking, most of the peach trees with striping phenomenon are not prepared for overwintering, which is caused by freezing injury and drought, or the resistance of the tree is poor, the tree potential is weak, and the striping phenomenon will also occur in the case of high temperature and drought. In addition, if the peach branches have more wounds and lose a lot of water in the case of intensified transpiration in spring, it will also lead to the death of peach branches.

2. Internal causes

The occurrence of striping of peach trees is closely related to the drought resistance of peach trees. The varieties with strong drought resistance have small lenticels, small total area of lenticels, well-developed protective tissues such as stratum corneum and cork layer, low plant respiration intensity and long time to break dormancy. Root system is more developed. The second is the state of peach trees overwintering, generally robust growth days, strong freeze-drought resistance, light striping, while weak plants grow poorly, weak photosynthesis, less nutrients accumulated before overwintering, strong freeze-drought resistance, so the more serious the striping. In addition, because the branches are not full, it does not form a good protective layer, so its freeze-drought resistance is the worst, and the striping is relatively heavy.

3. Preventive measures

First of all, the water should be strictly controlled, especially in autumn, the water is shallow from the late vegetative growth of peach trees to winter irrigation, and the soil water content should be reduced. If there is no autumn irrigation, excess water should be discharged to avoid planting intercrops that need more autumn water. Then it is to control fertilizer, especially nitrogen fertilizer, do not apply nitrogen fertilizer in the later stage, avoid overgrowth, and increase the application of phosphorus and potassium fertilizer to enhance the tree potential. At the same time, the plant growth can be controlled by coring, twisting and other pruning methods, and the prevention and control of diseases and insect pests should not be taken lightly.

4. Remedial measures

When the striping occurs, it can be re-cut before the flower, cut off the frozen dead branches and dead branches in spring, cut the extracted branches to the fresh part, and smear the special wound protective agent for fruit trees at the cut. Because of the strong wind in spring, the water evaporation of the tree is relatively large, so we can spray an appropriate amount of transpiration inhibitor on the frozen or striped trees to reduce water evaporation. At the same time, it is necessary to strengthen fertilizer and water management, supplement the nutrients needed by the plant, restore the tree potential as soon as possible, loosen the soil in time, ensure that the soil is loose and ventilated, and promote the growth and development of roots.

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