Causes and control measures of premature senescence of peach trees

Peach trees are one of the fruit trees that are easy to grow, with a wide planting area, but in the process of peach planting, premature senescence often occurs, which seriously affects the yield of peach trees and brings greater economic losses to fruit farmers. So what is the reason for the premature senescence of peach trees? How to prevent and cure it? Let's get to know it.

1. Causes of premature senility

1. Waterlogging and retting the root

The Rain Water season is bigger in the south, especially in the areas with higher altitude, where the cloud weather is bigger and the humidity is larger, but for those who like light and fear humidity, the root system distribution is shallow and the air is strong, if they are not afraid of humidity in time, it will seriously affect the growth and development of the root system, and even rett the root, resulting in premature senescence and death of the tree.

2. Lack of fertilizer

The heat in the south is mostly acidic, which is not up to the standard in planting, digging holes and pre-base fertilizer, and lack of transformation, so that the root system of peach trees can not adapt to growth. In addition, the orchard has inconvenient transportation, no application of organic fertilizer for a long time, partial application of chemical fertilizer, or even no fertilization for many years, which will lead to soil consolidation and poor permeability, resulting in physiological diseases of peach trees, such as yellow leaf disease, lobular leaf disease, fruit shrinkage disease and so on. cause early defoliation of peach trees, and die of normal premature senescence in severe cases.

3. Laissez-faire growth

Peach trees grow vigorously and generally enter the peak fruit period after four years of planting, but it is also easy to senescence prematurely, especially in the case of insufficient fertilizer and water, if the fruit is more, and the flowers and fruits are not thinned in time, or if the peach trees are allowed to grow and not pruned in time, this will cause the phenomenon of strong and weak on the crown because of the top dominance, which will lead to the death of the bore branches and premature senility.

4. Improper prevention and control

Due to the impact of wind and rain, resulting in tree loss and mechanical loss, but there is no timely treatment, not completely in winter, no protective agent, these will lead to premature senescence of peach trees.

II. Prevention and control measures

First of all, we should do a good job in water and fertilizer management, timely watering in drought, and drainage measures should be taken in the rainy season to avoid waterlogging and retting roots, resulting in premature senescence of plants. Organic fertilizer or farm manure should be applied before planting to improve soil structure and permeability, which is beneficial to root growth. Topdressing should be applied in time during the growing period, and human feces, urine and compound fertilizer are suitable. After peach trees enter the full fruit stage, it is necessary to expand holes and improve soil so as to improve the permeability of orchards and create good conditions for root growth and development. Thus delaying aging. Peach trees should be pruned many times in time every year, in which winter pruning is about and root plant potential is reasonable, so as to control crown density, shorten preventive transportation, reduce apical dominance and increase leaf photosynthetic area. to create favorable conditions for promoting flower bud differentiation and increasing fruit setting rate in the following year. During the growing period, the rainy buds should be erased in time, the effective photosynthesis of the crown should be increased, and measures such as ring peeling should be taken to form fruiting branches and reasonable thinning of flowers and fruits.
