Methods for pruning orange tree branches: short pruning and thinning, wiping the buds and spreading the tips.

1. Short pruning and thinning

Short pruning is what we often call short pruning, that is, cutting off part of the annual branches, and then retaining part of the original branches. The main purpose of shortening is to stimulate the sprouts under the cut of navel oranges, promote the growth of new and strong shoots, and enhance the growth ability and fruitfulness of navel oranges. Then thinning is to cut off the branches of the navel orange tree from the base.

Thinning can make the retained branches thicker and longer, improve the permeability of the tree, enhance the photosynthesis of the navel orange leaves, and is very beneficial to the differentiation of flower buds. It can significantly improve the fruit setting rate and fruit quality of navel oranges. Thinning pruning mainly targets diseased and insect-infested branches as well as leggy and overly long branches, with the principle of removing the weak and leaving the strong.

2. Wipe the buds and release the shoots

The buds of navel oranges should generally be wiped out in summer and autumn when the shoots grow to about two centimeters. remove. Then after applying the buds for many times, if you need to apply the buds again, if a large number of buds are allowed to sprout at the same time, the shoots will be released.

Because navel oranges have multiple buds, some sporadic buds that sprout early will cause other surrounding buds to germinate after erasing them, resulting in a large number of new shoots. Therefore, be careful to eradicate them multiple times. , until the shooting time stops. It is mainly used to wipe off the summer shoots of navel orange trees to prevent the summer shoots from robbing young fruits of growth nutrients and causing fruit drop.

Living Habits

Oranges are evergreen plants all year round. Oranges are native to the tropics and subtropics. They should be warm, not cold-tolerant, and relatively shade-tolerant. They require fertile soil with good water and air permeability. Mainly distributed in areas where the annual average temperature is above 15°C.

The lowest temperature for branch tips and seed germination of Tianchaicheng is 13℃. The optimal temperature range for branch tip growth is 23-31℃, and the growth stops at 37-38℃. But in the dry season, some old trees will also lose their leaves, and the leaves are also old. It is normal for old rocks to lose their leaves.
