The height of the tree is generally controlled below 250cm, the crown is open, the periphery is concave and convex, the branches grow healthily, the thickness of the green leaf layer is above 100cm, and the ventilation is transparent, resulting in a three-dimensional effect. Control the intersection between rows, and the crown coverage rate is 75% ~ 85%. Pruning suitable trees, deleting secrets and keeping sparse, removing the weak and keeping strong; Cut and stay, cut outside and stay inside; Cut down more trees and plant more flowers, and cut down less trees and plant less.
After the citrus tree entered the senescence stage from the full fruit stage, the vegetative growth was extremely weak, the senescence branches increased and the yield decreased. Renewal pruning is to cut off the aging part of the tree and promote it to form a new crown, thus improving the productivity of the old tree. Generally speaking, in addition to crown regeneration, root regeneration should also be combined with appropriate fertilizer to promote its growth.
The spring shoots of potted oranges must be pruned intensively before they germinate. First of all, we should remove dead branches, diseased branches, clustered branches, inward branches, cross branches and sprouting branches. Weakly cut strong branches, leaving 4 or 5 full buds; Strong pruning of weak branches leaves 2 or 3 buds, so that each branch can grow stronger spring shoots.
