Pruning methods of navel orange trees

Navel orange cultivation is very common in China, the yield of navel orange is high, the economic benefit is very considerable, so it attracts a lot of people to plant. When planting navel oranges, we need to do a good job of management, especially pruning. Reasonable pruning is a key measure to ensure the yield and quality of navel oranges, so how should we prune them when planting navel oranges? Today, the editor has brought you the method of pruning navel orange trees. Let's take a look at it.

1. Short cut and sparse cut

A short cut is what we often call a short cut, that is, the part of the annual branch is cut off and then part of the original branch is retained. The main purpose of short cutting is to stimulate the sprouting under the cut mouth of navel orange, promote the emergence of new and strong shoots, and enhance the growth ability and fruiting ability of navel orange. Then thinning is to cut the branches of the navel orange tree from the base. Thinning pruning can promote the thickening and lengthening of the retained branches, improve the permeability of the tree, and enhance the photosynthesis of navel orange leaves, which is very beneficial to flower bud differentiation. It can obviously improve the fruit setting rate and fruit quality of navel orange. Thinning is mainly based on disease and insect branches, long branches and over-long branches as the main pruning objects, with the principle of getting rid of the weak and staying strong.

2. Wiping buds and putting shoots

The sprouting of navel oranges should generally be carried out when the summer and autumn shoots grow to about two centimeters, wiping out some worthless buds that do not need buds. Then after many times of wiping buds, when you no longer need to wipe buds, if you let a large number of buds sprout at the same time, it will be released. Navel orange is a compound bud, for some sporadic buds picked early, after erasing, it will cause other buds around to sprout, thus sprouting a large number of new shoots, so we should pay attention to erase repeatedly until the shooting time stops. It is mainly used for navel orange trees to erase summer shoots to avoid the phenomenon of fruit drop caused by summer shoots robbing the growth and nutrition of young fruits.

3. Pick the heart and relax slowly.

In fact, heart-picking also belongs to a kind of short-cut, and proper heart-picking is very beneficial to the growth of branches. It can improve the nutrient accumulation of trees and enhance the growth ability of branches. When the new shoot grows to a certain length and is not lignified, the top of the shoot can be removed directly. In July, the elongated and overgrown branches of summer shoots are removed to promote branches. Then in October, the coring of the long shoot is beneficial to the differentiation of flower buds. Slow release is the navel orange growing within a year without any pruning, let it grow, until flowering and fruiting, the main object is the fruiting mother branch.

4. Retractive ring cutting

Retraction is to cut off some perennial branches from the branches of the navel orange tree. It is generally used on adult trees where the tip of the big branch declines or there are few bore branches in the crown to renew the big branch of the crown. It can improve the internal permeability of the crown and enhance the tree potential. Ring cutting is to cut off the phloem of a branch with a knife all the way to the xylem without harming the xylem. The main purpose is to limit the transport of phloem, avoid the transport of nutrients to the lower part of navel orange trees, and improve the accumulation of nutrients above the ring cutting position.

The above is a brief introduction to the pruning methods of navel orange trees. That's all for today's introduction. This article is for reference only. I hope it can help you all.
