Causes and preventive measures of bald inner chamber of peach trees

Peach tree is a light-loving tree species with easy cultivation and management, strong adaptability, juicy and delicious fruit, rich nutrition, in addition to fresh food, but also can be processed into succulent food, such as canned, over-dried, candied and so on. However, in the process of planting, because of improper pruning, the inner chamber branches are thin and weak, and in serious cases, the inner chamber is bald, which leads to the outward movement of the fruit part and the decrease of yield. So how to prevent the inner chamber of the peach tree from drying up? Let's have a look.

First, the reason for the baldness of the inner chamber

There are many reasons for the baldness of the inner chamber of the peach tree, one is the early defoliation, the poor frost resistance of the leaves, resulting in early shedding, weak branch growth, low photosynthetic efficiency, reducing the accumulation of nutrients in the tree, easily forming secondary branches and aggravating the baldness of the inner chamber. The second is the result of the big and small year, the peach tree big and small year is the main cause of the inner chamber baldness, the big year yield is high, the nutrient consumption is big, causes the inner bore branch reason accumulation to reduce, causes the branch thin and weak, the flower bud is not full; but in the small year, the yield is low, the plant nutrition accumulation is much, causes the branch growth dense and prosperous, extremely easy to form the only long branch, causes the permeability is poor, easy to cause the branch death. Third, improper shaping and pruning, when the inner bore branch is too dense, the long branch is not removed in time, and the opening angle of the main branch is small, which will cause the inner bore branch to be bald.

II. Preventive measures

1. Cultivate the main branch

The top dominance of peach trees is strong, and the extended branches of the main branches can be trimmed gently without starting, so as to weaken the tip dominance and promote the formation of flower buds and the growth of branches in the lower part of the crown. The main branch is cultivated into curved and extended growth, which makes each long potential uniform and promotes the growth and development of the lower part of the branch. in winter shearing, the angle of the main branch is increased year by year, so that the main branch is curved and extended.

2. Angle of opening main branch

When the angle of the main branch is too large, the permeability is poor and the tree shape is disordered, which can easily cause dense and prosperous branches on the back and cause the fruit part to move outward; on the contrary, the opening angle of the main branch is small, and the tree potential is strong and weak. According to the practical investigation, the angle of the natural happy main branch of the peach tree should be 60 °to 70 °. For the varieties with more upright posture, the main branch angle can be opened by changing the head of the back branch and falling, pulling, supporting and other measures.

3. Thinning flowers and fruits

Flower thinning and fruit thinning can be carried out according to the order of branches from top to bottom and from the inside to the outside. On the same branch, the flower thinning apparatus is incomplete and the flowers grow together, thin florets and late flowering. On the same peach tree, the fruit thinning first removes dense fruit, deformed fruit, disease and insect fruit, weak small fruit, and then removes the fruit with short stalk and leafless fruit near the fruit.

4. Reasonable pruning

Pruning can regulate the contradiction between regeneration and senescence, growth and growth, fruit and growth of fruit trees, so as to keep a balance. Pruning can make the rational distribution of branches and leaves, improve the permeability of orchards and crowns, maximize the use of various, and increase yield and quality.

5. prevention and control of diseases and insect pests

The diseases and insect pests promoted by peach trees include bacterial perforation disease, peach leaf shrinking disease, aphids, peach leafhopper, leaf miner, etc., which can be prevented by spraying stone sulfur mixture or Dysen zinc when clearing the garden, and then prescribe the right medicine when the disease occurs, and get rid of it thoroughly.

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