How to prune pomegranate trees? The pruning methods are different in each growth stage!

It is very necessary for any fruit tree to prune during its growth, and pomegranate trees are no exception. The pruning of pomegranate trees is mainly divided into two stages: summer and winter. The main purpose of summer pruning is to wipe buds, thinning branches and pulling branches. In winter, it is mainly sparse to grow branches, strong branches, senescent drooping branches and parallel branches, so how to prune pomegranate trees? The pruning methods are different in each growth stage!

1. Pruning of young trees

During the winter pruning in the first year, among the new branches germinated in the 30cm under the cut mouth, three branches with uniform distribution were selected as the main branches, the 60cm was truncated, and the other branches were thinned.

In the second year of winter pruning, one side branch was left on each main branch, three main branches were kept on the same side as far as possible, and each main branch was cut short by 60cm.

During the winter pruning in the third year, the second side branch is selected on the opposite side of the first side branch, and the length of the branch is extended or cut lightly. attention should be paid to pulling the main and side branches according to the requirements of the tree shape every year, and the shaping can be completed in 3 ~ 4 years.

2. Pruning of trees in full fruiting period

Pomegranate trees at full fruiting stage should keep the crown sparse and dense inside, large branches and small branches dense, timely remove redundant overgrown branches, disease and insect branches, thin and weak branches, etc., pay attention to adjust the balance between tree growth and fruit, and remove some prosperous long branches in winter. Leave as many short fruiting mother branches as possible, growing seasons pull branches, weak trees should pay attention to the retraction and rejuvenation of weak backbone branches and branch groups, and drooping branches should retract and raise their heads. Pay attention to the update and rotation results of the branch group.

III. Pruning of aging trees

1. Retract the main and side branches of senescence

For the front drooping and weak main and lateral branches, retract to the upward growing branches to restore their growth potential, for the rear bald main and lateral branches, retract to the posterior part of the branches, or make use of the sprouting branches or long branches in the back of the next year, combined with the growing season to cultivate new main and lateral branches step by step.

two。 One-time renewal and transformation

The senescent plants were sawed off from the ground in winter, and in the second year of winter cutting, 1 and 3 of them were selected from the sprouting tillers as new trunks, and then re-cultured.

Fourth, the four seasons pruning of pomegranate

1. Spring pruning

Spring buds are suitable for pruning when they are just formed. Generally in mid-April, the ratio of fruiting branches to vegetative branches is first adjusted by pruning to cut off fine twigs to reduce nutrition consumption, followed by sparse buds and bell buds pinched out by hand, leaving tube-shaped flowers and gourd-shaped flowers. Gourd-shaped flowers are normal flowers. Due to the rapid growth of flowering flowers, it is necessary to pick flowers two or three times, and at the same time, spring pruning should also pay attention to pruning diseases and insect pests.

two。 Summer pruning

Summer pruning is generally carried out from June to July, and fruit thinning is needed to ensure fruit quality and yield. for a branch with many fruits, it is necessary to remove small fruit, weak fruit and diseased fruit, leaving big fruit, pomegranate results are generally divided into three stubble, it is recommended to keep more first stubble fruit, and the rest can be removed completely. For branches that grow too dense, cut off long branches and fruitless branches to ensure air permeability and light permeability.

3. Autumn pruning

Autumn is the season for fruit ripening, cutting off germinating new branches, growing branches, and diseased branches, reducing nutrient consumption, increasing ventilation and light transmission, promoting fruit enlargement, conducive to ripening, cutting off buds from roots after fruit harvest, promoting flower bud differentiation, and ensuring fruit yield next year.

4. Winter pruning

Winter pruning should be carried out before sprouting after falling leaves, cutting off dead branches and random branches to ensure that there is a certain space between the main branches and side branches. for branchlets, keep the strong growth, many and full flower buds, and cut off the small and weak ones.

The above is the introduction of the soil flow net to the pomegranate tree pruning methods in different growth stages and different seasons. Pomegranate trees are pruned every year, otherwise long branches and diseased branches will affect the fruit yield and fruit quality of fruit trees. reasonable pruning can ensure fruit setting rate and promote fruit growth.
