How to prune pomelo trees and pruning skills of pomelo trees.
Young tree shaping
After the seedlings are planted, they are cut and dried 30-40 cm above the seam. After pruning, select 3-4 new shoots with vigorous growth, uniform distribution around them and a certain interval between them as the main branches, and erase the rest. When the top of each main branch continues to extend to about 40 cm, it should be picked in time. On each main branch, choose 2-3 robust branches with appropriate positions as auxiliary main branches. Proper spacing should be kept between the main stem and the auxiliary main branches, so that the lateral branches of meristem can receive good light. Always wipe off the branches that cross, overlap and disrupt the tree, and the branches and buds that are not in place.
fruit tree pruning
Generally speaking, pomelo fruit trees only shoot in spring, with few shoots in summer and autumn, and have strong fruit-bearing ability. Therefore, the pruning of the first-bearing trees should be light rather than heavy. Generally, there are only overgrown branches, pests and diseases, dead branches, too dense and delicate branches, etc. If the location is improper, the branches should be thinned and more internal branches should be left, so the mother branches should not be cut short. The crown of adult trees has been formed, and the pruning objects are mainly the lateral branches on the main branches and various branches on them, with the aim of adjusting the balance between growth and fruit. The principle of pruning is that strong trees should be sparse, few short and dense branches, upright branches and lateral branches should be sparse, and drooping branches and weak branches should be left to facilitate flowering and fruiting. Weak trees mostly bear fruit on strong branches, so measures should be taken to remove the weak and keep the strong, and more leafy fruit branches should be kept.
Regeneration of aging trees
The best time for regeneration and pruning of old trees is before the germination of spring shoots or after the stop of growth, and 5-6 months before the occurrence of summer shoots. Old trees should be bare and updated, and the main branches and auxiliary branches should be retained when updating. All the 3-4 year old lateral branches on the crown should be cut off, and no leaves should be left on the crown to promote the occurrence of strong branches. COVID-19 can be formed within 1-2 years after germination and shoot control, and the results can be recovered. For some rotten branches that still have the ability to bear fruit, a part of them can be updated every year and a whole tree can be updated in 2-3 years through rotation.
