Pruning methods of pomelo trees

Grapefruit trees are widely distributed in southern China and usually grow in hilly areas. The fruit of grapefruit is also loved by many people because of its high nutritional value and good taste. When planting grapefruit trees, we need to do a good job of pruning. Reasonable pruning is very beneficial to the yield and fruit quality of grapefruit trees. So how to trim the grapefruit tree? The following editor brings you the method of trimming the grapefruit tree. Let's take a look at it.

1. Pruning at the young tree stage

After planting the grapefruit seedlings, we have to cut and dry the grapefruit seedlings about 35 centimeters away from the grafting interface. When the grapefruit tree shoots, and then choose about three strong growth, uniform distribution and spacing between the new shoots as the main branches, the excess will be erased. When the top of the main branch grows to about 40cm, do a good job of heart-picking and topping. Then there are about 3 robust branches left and right secondary branches on the main branch. Among them, the main branch and the secondary main branch should keep a certain interval to ensure that the meristematic lateral branches can receive sufficient light. Then some branches that overlap and disturb the tree should also be erased in time.

2. Pruning in the fruit period

When pomelo trees bear fruit, the inner chamber branches are generally more fruiting. Therefore, for the initial fruit tree, the pruning strength should be light, not heavy cutting. Usually only for some growth position should not be too long branches and insect pests and diseases can be cut off, retain more inner bore branches, can not be pruned to fruit mother branches. For adult trees, because the crown is basically formed, the main pruning objects are the side branches and other branches on the backbone branches. This pruning is mainly to ensure that the growth and fruit of the grapefruit tree can be balanced. For strong trees, it is necessary to re-cut properly, reduce short clips, remove some branches that are too long and too dense, and retain some drooping branches to increase the amount of flowers and fruits of fruit trees. Then the weaker trees should be pruned according to the principle of getting rid of the weak and staying strong, and more leaves and fruit branches should be retained.

3. Pruning during aging

When the grapefruit tree begins to enter the senescence period, it should be carried out before and after spring shoot growth and in May-June. For old tree pruning, we should give priority to explicit pruning, and keep an appropriate amount of main branches and secondary main branches when renewing branches. For the 4-year-old lateral branches in the crown, all the lateral branches should be cut off, and the leaves should not be retained on the crown to ensure the growth of strong shoots. Then after sprouting and updating, we will do a good job of wiping buds and controlling shoots. A new crown can be formed in about two years and bear new fruit. Finally, for some declining branches that still have the ability to bear fruit, they can be rotated and updated within three years.

The above is a brief introduction to the pruning methods of grapefruit trees. When pruning the grapefruit tree, we must pay attention to adjust the pruning method reasonably according to the growth period of the grapefruit tree to ensure the normal growth and improve the permeability of the grapefruit tree, so as to ensure the yield and quality of the grapefruit tree. That's all for today's introduction. This article is for reference only. I hope it can help you all.
