When is the best time for apricot pruning?

The pruning of apricot trees is the best from the end of May to the beginning of June, during this period, keep the ones with 7-12 angles, then cut off all the remaining branches, spray urea on the trees in the first ten days of November to let the leaves fall early. Apricot trees need different pruning methods at different growth stages, which can improve the yield and fruit quality of fruit trees.

When planting apricot trees, in order to improve the fruit setting rate of apricot trees, apricot trees should be pruned at the right time every year during the planting process.

Pruning time of apricot trees

Generally, from the end of May to the beginning of June, the fixed drying will be carried out, and the better ones with 7-12 angles will be selected, and the rest will be cut off. When the new is slightly longer than about 40cm, choose 3 or so for key training, carry out "V" shape or happy shape pruning, the rest of the new should be removed twice, the upright on the back should be repeatedly removed, and the branches that are too dense will be wiped off. Urea is sprayed on apricot trees in early November to promote early leaf fall.

2. Pruning methods of apricot trees

1. Fruit expansion period

The new trees can be removed or twisted slightly to prevent "growing trees on the tree" and deteriorate the internal light of the crown. After uncovering the film of the fruits harvested in the first and middle of May, the retraction and thinning will be combined to ensure the balance of tree growth and prevent compensatory growth.

2. Young tree stage

When pruning trees in winter, both shaping and fruiting should be taken into account, the main branches, lateral branches and extended branches should be trimmed lightly, and those with full-length branches should be cut short. The developing branches with moderate growth and relatively open angle should be released slowly to promote the germination of medium and short branches, increase the number of fruiting branches, and retract and culture into fruiting branches in time after flowering or fruiting. Medium and short branches with a larger angle will be easier to grow into flowers, so try not to prune them.

Young trees with weak growth should be cut short properly, the overdense branches and thin and weak branches should be removed, the strong branches should be retained, and the erect strong branches should be flattened as auxiliary branches to promote the development of stout medium and short fruit branches.

3. Full fruiting period

Appropriate pruning should be carried out according to the specific conditions of the branches in order to maintain the stability of the fruiting position and growth. The weak main branches, lateral branches and perennial auxiliary branches are retracted where there are strong branches, so as to restore the growth momentum of the trees, renew the lower part of the crown and inner bore branches in time, and let the fruit trees continuously produce new strong fruiting branches. this can achieve the purpose of increasing production.

4. Aging period of fruit trees

It is necessary to change the head or retract in the more upright branches in order to promote the regeneration of hidden buds. The well-positioned overgrown branches can be cultured into backbone branches and fruiting branches. When pruning the fruiting branches and fruiting branches, the strong branches should be left and the lateral buds should be renewed and pruned. The tree is particularly weak, and the renewal of trees that cannot be effective can be carried out under the management of strengthening fertilizer and water, and the whole tree can be renewed in 10-15 years. In that year, a large number of new branches will sprout, sprout and coring in summer, and pruning in winter will blossom and bear fruit the following year, and the yield will be restored.

In the process of planting apricot, the diseased and dead branches that will absorb the nutrition of apricot should be cut off in time, so as not to affect the growth and development of apricot.
