The main points of the course of the latest pruning techniques of pomegranate trees

Fruit trees in different growth stages, its pruning is different, and pomegranate can be divided into summer pruning and winter pruning, summer pruning is mainly bud, pull branches, and winter is mainly thinning, the following and small series together to see pomegranate pruning technology points bar.

1. Young tree pruning

After planting 70 cm in the stem, the first year of winter pruning, from the pruning within 30 cm of the germination of new branches selected from 3 evenly distributed branches, as the main branch culture, leaving 60 cm short, the rest of the branches thinning. Growth and pull 3 main branches, pull branch angle should be determined according to tree requirements. When the winter of the second year is cut, each main branch can be selected to leave 1 lateral branch, 3 main branches as far as possible on the same side to leave branches, each main branch extension branch to stay 60 cm short. In winter shearing in the third year, the second lateral branch is selected from the opposite lateral branches of the first lateral branch, and the extended branch is long put or gently cut off. Generally, the shaping can be completed in 3-4 years.

2. Fruit tree pruning

Pomegranates in full fruiting period should keep the crown "thin and dense, thin outside and dense inside, thin branches and dense twigs", so we should timely remove redundant long branches, excessive branches, inward branches, cross branches, overlapping branches, diseased branches, thin branches, etc. At the same time, attention should be paid to the balance between tree growth and fruit. In late trees, some of the long branches should be thinned in winter, and as many short fruit mother branches as possible should be kept. In growing season, branches should be pulled. Weak trees should pay attention to retraction and rejuvenation. Drooping branch groups should retract and raise their heads. Attention should be paid to the renewal of branch groups and alternate fruit.

3. Senescent branch pruning

Senile branches are mainly recovered, rejuvenated and renewed. For the main branches that droop and weaken at the front, they are retracted to the branches growing upward to restore their growth. For the main branches that are bald at the rear, they are retracted to the branches growing at the rear, or the branches that are vigorous at the rear of the next year are deciduous. Combined with the pulling of branches in the growing season, the main branches are gradually cultivated. In winter, the senescent plants should be sawn from the ground, and in the winter of the next year, one to three new stems should be selected from the sprouts, and then re-cultured. This is renewal.
