As one of the fruit trees with good economic benefits, peach trees have been cultivated in a large area for a long time. However, in recent years, the author found that with the aging of peach trees in some orchards, some peach trees planted for about 10 years generally have the phenomenon that the base of the main branch is bare or the base branch is weak and does not bloom, and the fruiting part moves outward. What effect does the outward migration of the fruiting parts of peach trees have on production? How to improve?

Why do peach trees have fruit parts moving out?

The management of soil, fertilizer and water in orchard is not in place.

Some fruit farmers don't understand the characteristics of peach trees that need fertilizer and water, or ignore the phenology of peach trees in management, which leads to excessive watering of peach trees. In addition, there is more rain in summer, and the amount of nitrogen fertilizer used by fruit farmers is too large, which easily leads to the phenomenon that peach trees flourish. If the pruning is unreasonable at this time, it will lead to the stagnation of the tree, the internal branches will not grow and die, and the resulting parts will move outward. In addition, if some orchards have poor soil and insufficient fertilization, peach trees will weaken and their inner branches will form "vulnerable groups".

The application of peach growth habits is not in place.

The top advantage of peach tree growth is very strong, coupled with the characteristics of peach tree like light, branches often grow to high places. If management is not timely and in place, the growth potential of the lower part of the plant will be weakened, and sometimes the lower branches will die and the lower part of the plant will be bald. The buds of peach trees are precocious and can germinate 2-4 times a year. At this time, if good pruning measures are not taken, the whole branch will be crowded and the ventilation and light transmission will be poor. Coupled with the characteristics of peach trees that like light, the inner branches that can't see light are easy to die, and the resulting parts will move outward.

Peach trees are not properly pruned.

The purpose of peach tree pruning is to shape the tree shape on the one hand, and to control the tree potential on the other hand. However, in the aspect of peach tree pruning, some fruit farmers leave branches too densely in winter, or adopt the method of pruning short branches, which easily leads to the phenomenon that new branches are luxuriant in the periphery, many branches are thick, the upper part is strong and the lower part is weak, and the bore is bare, which leads to the outward migration of the parts. In addition, in order to save trouble, some fruit farmers do not prune in summer, which will lead to the trunk and branches of peach trees stretching straight and the branches on the back of peach trees growing wantonly. In severe cases, the diameter of branches is as high as 3cm, which not only affects the ventilation and light transmission of the tree, but also aggravates the phenomenon that the fruiting parts of peach trees move outward.
