Ficus carica is an exotic tree species, which was introduced to China in the Tang Dynasty. It has been cultivated for about 1300 years. It can be cultivated in most areas of China and has the advantages of early fruiting, long life, simple management and good economic benefits. In fact, fig pruning is not troublesome, because fig itself has a weak ability to form branches, and the pruning amount is very small after growth. Let me briefly talk about the pruning of fig trees. It is not surprising that the fig tree mentioned by the subject is almost 1 m high, but it has no fruit and no topping. Ficus carica generally grows for 2-3 years and begins to bear fruit. Ficus carica trees aged 6-7 years enter the full fruit period, and their life span can be as long as 100 years.

First, plastic fig trees should be dwarfed, because the root distribution of fig trees is relatively shallow. If the trunk is set very high, the center of gravity of the tree will move up and it will be easily blown down or broken by the wind.

If the fig tree is potted, it must be dried in time, and the height is about 30 cm. Several useful branches can be left in the plastic belt on the trunk as the main branches for heavy and short cutting and cultivation. After leaving the main branches on the trunk, the extension branches on the upper part of the trunk should also be cut short, and then the formation of the second layer of main branches can be cultivated by pulling branches, binding and fixing, and the height of the tree can be controlled at about 1 m. If there is only one layer of main branches, it can be cultivated into a happy shape with many main branches.

There are two main kinds of fig trees, one is the horizontal "X" shape, and the other is the natural happy shape. Here are the different pruning methods of these two attributes.

Second, the shaping and pruning methods of two attributes of fig tree The first one is the shaping and pruning of horizontal "X" tree.

1, the characteristics of the tree

This tree-shaped fig tree requires a stem height of about 40 cm. Generally, four main branches are left, which extend outward in a horizontal "X" shape, and each main branch is left with fruiting mother branches at intervals of about 20 cm.

2. Cultivation of trees

To plant annual fig seedlings, the stems are 30-40 cm high. Four angles should be reasonably selected for the sprouted new branches, and the symmetrical new branches should be cultivated into four main branches in the shape of "X", and the rest new branches should be thinned out.

When cutting in winter, determine the length of four main branches. It is not advisable to leave long branches in that year, otherwise the fruit will affect the growth of the main branches and may split the branches from the base. Generally, you can leave a short film of 70-80 cm. When the main branch is cut short, the outward bud is left to extend the main branch, and the incision is in front of the left bud to prevent the stem from shrinking and dying. Spring pruning must be carried out before the sap flows in late March, otherwise it will cause the sap to flow and weaken the tree.

For two-year-old fig trees, the fruiting branches can be cut short and cultivated into lateral branches, that is, the future fruiting branches, or mother branches. The vertical buds on the back of the main branch are all thinned, and the lateral buds are kept at a certain distance, and they are cultivated into fruiting branches of the current year or the following year. The main branches sprout new buds for further extension.

In the third year of fig tree, the main lateral branches are basically shaped, and then they can be adjusted as needed. The high fruiting mother branch should be properly cut short, leaving weak branches or buds as the head, and the low fruiting mother branch should be long to promote balance. The mother branch at the base of the main branch must have internal buds or lateral buds, otherwise it will be too long to operate and manage.

Second, the shape shaping and pruning of natural happiness.

Natural and happy fig trees are the best. The fig saplings planted in that year can be cut off by about 40-60 cm, and the new branches from the base can be cut off by 4-5 in the next year, and the rest can not be left, so that a happy tree can be cultivated.

1, the characteristics of the tree

The trunk of a happy fig tree is generally about 50 cm. The whole tree has three main branches extending in three directions, and the crown is round.

2. Cultivation of trees

The stem height of the seedlings in that year was 40-60 cm. In April, three new shoots were selected from the trunk as the main branches and tied with bamboo to prevent sagging.

When pruning in the spring of the first year, the main branch should be cut off to 50-60 cm long, leaving external buds or lateral buds at the incision.

In the second year, each main branch leaves 3-4 new shoots to grow horizontally. When pruning in winter, the main branch is extended by 30-40 cm, and the other branches are shortened by about 20 cm.

In the third year, according to the operation steps of the second year, after pruning for one year, each tree can leave 20-30 fruiting branches. When pruning in spring, the oblique branches are reserved as side branches, and the front ends of the main branches and side branches are reserved with short joints of about 20 cm, and the rest of the fruiting branches are reserved with 2-3 short joints.

After 4 ~ 5 years, when the leaves are spreading in spring, we should remove too many and too dense buds, leave about 50 fruiting branches per plant, and keep 1-3 nodes for repeated short cutting, but pay attention to the direction of each bud cutting, and it is advisable that the new branches do not overlap and cross, and remove the too dense and crowded branches.

If the fig trees of the subjects are potted, the fruiting branches of 2-3 years old can be cut short at a height of about 60 cm in July, and then 4-5 buds are left at the top to form the main branches, and the rest buds are all drained. After the main branches germinate, select 3-4 suitable main branches, and leave 65,438+0-3 terminal buds on each main branch to form side branches, and the left branches should be evenly distributed. The branches of potted fig trees are short and dense, and will collapse and be pruned again after 4 years. In order to occupy less indoor space in winter, you can fan up the crown and put it aside.

In a word, the fig tree of the subject has no fruit, which may be because it is not yet old, and then it is poorly managed. Close to the height of 1 meter, it is high time to start plastic surgery. You can do plastic surgery according to my suggestion, or you have other good methods. Can we discuss one or two?
