When the base of apricot branches has been semi lignified, it is the appropriate time to pick the heart. The time of heart picking is from the new branches to the end of May. Generally, the strong branches are about 20cm, which can promote the growth of branches and increase the number of leaves, and lay the foundation for the fruiting branch group. The weak branches were left about 30 cm to promote the formation of full flower buds. Those planted in the same year do not need to remove the heart, because the growth is slow at this time, and the removal of the heart is not conducive to the development of the root. And can also carry on two or three times to the vigorous long branch.
Branching is to increase the angle between new shoots and branches, which is usually used in young trees and early fruit trees. It is suitable to be carried out from the first half of May to the first half of June. Through the opening angle, change the angle and direction of Apricot Branches, so as to control the top advantage, improve the lighting and ventilation conditions, conducive to the cultivation of a large number of fruiting branches.
The twigs are generally carried out from July to August. Under the action of external force, the new vigorous branches can grow downward, left or right, or they can change their growth direction by binding them on their own or other branches of trees. The advantage of twig bending is that it can inhibit the growth of twigs, promote the germination of short branches and the formation of flower buds.
Thinning was mainly carried out in the first few years after apricot planting. From the end of June to the beginning of July, it is better, because the branches are soft, easy to break, and the wound is easy to heal. Pruned apricot trees also need regular inspection, according to the situation to remove the new branches.
