In the case of natural production, the tree body is often gratifying, and the middle trunk grows weakly and easily disappears. Without pruning, the top of the crown has obvious advantages. The peripheral branches grow vigorously, and the branches in the lower part of the crown and the inner cavity often don't get enough light, which is easy to cause the early defoliation of new shoots and the premature death of branches, resulting in the bare branches in the lower part of the tree and the inner cavity. The ecological conditions of long-term drought and strong light have cultivated the characteristics that peach trees need high light and strong drought resistance.
Usually, the pruning of the extended branches at the top of the periphery should pay attention to leaving fewer branches, leaving a weak branch or a weak bud with a strong branch as the head. When pruning young flourishing trees, the main branches are uniaxially extended, and the extension head of the main branches can be extended by about 50 cm. After two or three years, the growth potential of the tree tends to ease, and then the golden mean branch retracts to the appropriate direction as the extension head. For the overgrown extension branches, the pruning method can also be adopted, with a short tip weight and an intercept of 10 ~ 15cm as the extension head, and a large lateral branch is left under it for extension growth.
Introduction of peach trees
Peach, Rosaceae, Prunus. Small deciduous trees. Leaves narrowly elliptic to lanceolate, length 15cm, width 4cm. Long and slender, with fine teeth at the edge and dark green luster. There are nectaries on the leaf base. The bark is dark gray, and cracks appear with age. Flowers are solitary, from light to dark pink or red, sometimes white, with short stalks and a diameter of 4 cm, and bloom in early spring. Nearly spherical drupe with hairy surface and edible meat, orange yellow and reddish.
Peach is a small deciduous tree with fruit as fruit. Flowers are visible and fruits are juicy. It can be eaten raw or made into peaches and canned peaches, and its nucleolus can also be eaten. The flesh is white and yellow, there are many varieties of peaches, and the peel is generally hairy. Nectarine skin is smooth; The fruit of "Flat Peach" is flat and discoid, and "Bi Tao" is an ornamental peach tree with different petals. Originally from China, it is widely cultivated in various provinces. It is cultivated all over the world.
