Pomegranate winter management technology
Pomegranate trees are plastically trimmed in winter, after defoliation and before germination. Focus on the removal of roots and cut off long branches, overly branches, thin branches, diseased branches, drooping branches, cross branches, overlapping branches and so on. Pomegranate trees should be properly pruned according to different ages and different tree potentials. Pay attention to the following points when pruning:
In the first year after planting, all the branches and leaves are preserved, and trees are raised to promote growth.
In the second year, the tree shape was selected to keep the backbone branches, and the slender branches on the trunk and the sprouts on the ground were all removed. Pay attention to keeping the branches on the trees as much as possible. Generally, short cuts could not be used, and the branches that were too dense could be removed.
For the first fruit trees, it is necessary to pay attention to cultivating the lateral branches and the resulting branch groups, with light shearing and sparse branches; to strong branches, to stay in moderately weak branches, to erect branches, to keep horizontal oblique branches; to go to diseased branches, to keep strong branches; Sparse or cut off, change direction, etc., so that the crown is moderate and achieves the purpose of opening a good flower and good fruit.
For the fruit-bearing period, the original structure of the canopy should be maintained, and the tree should be kept moderate and strong. For the excessively strong branches in the upper part of the tree, the growth should be moderated. Excessive side branches should be removed or shrunk as appropriate, close to the erect backbone. Branches should pay attention to increase the growth angle. In order to maintain the growth of the tree body, it is possible to rotate and renew the complex branch group.
When pomegranate trees are pruned in winter, all the pests and branches should be removed or cut off to reduce or eliminate the reinfected pests.
The wounds caused by pruning should be closed in time to prevent cracking and pollution. By applying the callus anti-corrosion film, the tree body forms a protective film; the pathogens in the tree body are suffocated to death, and the invasion of pests and diseases is prevented outward; the growth of the wound healing tissue is protected, and the tree potential is well restored.
