When is the best time to graft fruit trees? How do you graft it?

The time of grafting fruit trees will generally be selected in early spring, summer and autumn, but it is also necessary to pay attention to avoid the hot time period when grafting, for example, do not graft in midsummer, the survival rate of grafted fruit trees will be very low at this time, because the climate conditions at this time are high temperature, water evaporation is fast, if you can not replenish water in time, the grafted seedlings will lose all the water due to transpiration, wilt and die.

The most commonly used methods for grafting fruit trees are: bud grafting, which is the most widely used grafting method, and the specific methods include "T" shaped bud grafting method, square budding method and intercalation bud grafting; Grafting is a grafting method that uses the branches of fruit trees as scions; There is also tongue jointing, which is based on the horse-ear-shaped long cut surface, cutting a knife to form a tongue-shaped cutting surface, and then inserting the scion and the rootstock; Grafting, grafting is to tie two plants with similar branch thickness together, and grafting is a grafting option with a high survival rate.

When the fruit tree is grafted, it is also necessary to graft the length of time, for example, practice shows that the best grafting period for most fruit trees is to graft during the rootstock germination period, and the survival rate is relatively stable, if the plastic film is fully enclosed and bandaged, or the scion used is wax sealed, the grafting period can be appropriately advanced by 7 to 10 days.

At present, fruit tree agriculture is a large part of rural agriculture, and farmers' enthusiasm for green, ecological and other construction is very high. This can greatly improve the production enthusiasm of fruit farmers. Therefore, our fruit tree technicians need to go deep into the countryside to teach the rural fruit farmers and farmers the correct way to care for and produce fruit trees, improve the correct methods of fruit tree care and fruit harvesting for fruit farmers, and grasp the personality of fruit trees in specific operations.

It is better to reduce the price from May to June, because it can better promote the growth of fruits and vegetables, and can better promote results. You can first cut the wood with a knife, then attach the variety of another fruit tree to it, and then wrap it in plastic film.

1. Fruit tree grafting is usually carried out in spring, and the best grafting time period is between the stunning festival and the spring equinox festival every year, when the bud buds have not yet germinated, and the survival rate of grafting is high. The grafting time should not be too early, because the temperature is low, the growth activity of fruit trees is poor, and the survival rate of scion is not high. The grafting time should not be too late, the bud bud germinates and grows, which will emit a lot of water and affect the survival rate of the scion.

2. When grafting fruit trees, graft in a timely manner. Neither too early nor too late, both will affect the survival rate. To choose a thick fruit branch grafting, pick the buds to pick strong buds.

Choose grafting on non-rainy days to prevent rainwater infection and affect survival. Both the grafting knife and the wrap should be sterile to avoid infection and affect the survival rate. The grafting edge should be smooth, increase the degree of anastomosis between the knife edges, and improve the survival rate.

The knife edge should be bandaged tightly and sealed to avoid the loosening of the scion and the impact of rainwater on the survival rate. After the fruit tree is grafted, protective measures should be added to avoid strong winds, human and animal contact, impress the scion, and affect the survival rate.

First, the time of grafting.

Fruit tree grafting is best in spring, around March. Because the rootstock buds are just beginning to germinate at this time, the wound caused by premature grafting is slower to heal and is prone to pests and diseases. Too late will affect the growth of fruit trees, and even cause death in winter.

Therefore, grafting is best done about 10 days before germination. Also, pay attention to the weather, which should be when the weather is clear.

Second, the method of grafting.

There are many ways to graft fruit trees, and from the perspective of the use of scion, they are mainly divided into branch grafting and bud grafting. From the perspective of the grafting site, it is divided into root grafting, double grafting, abdominal grafting, rhizome grafting and high grafting. If you look at the form of the interface, it is divided into cutting, splitting, insertion, tongue, leaning, and plugging bud joint, etc.

3. Post-grafting management.

1. Pest control: Fruit trees should pay attention to strengthening management after grafting, because they are easy to suffer from various pests and diseases during the grafting to germination.

2. Get rid of the tillers: There will be tillers on the rootstock about ten days after grafting, which should be removed in time, otherwise it will affect the later growth. If the joints of the rootstock are small and thick, do not remove them all, but leave some parts far away from the joints.

3. Patching: After grafting, it should be checked frequently, and if it is found that it is not alive, it should be repaired as soon as possible.

The time to graft fruit trees is mostly in spring, summer and autumn, and spring grafting is the best.

Because in spring, when the temperature rises and the sap flows, the water and nutrients of the fruit tree roots are transported upward, which is most conducive to grafting and survival. Therefore, in order to achieve the purpose of saving labor, saving materials and high survival rate of grafting, people choose to graft in the spring when the climatic conditions are most suitable.

However, due to the different climatic conditions in different places and the different climate changes in the same area every year, the grafting period should not be set too rigidly, but the appropriate grafting period should be flexibly determined according to the local climatic conditions and the different species of grafted trees. Generally speaking, in the northern production areas dominated by deciduous fruit trees, if you choose grafting, the time is roughly from late March to early May, that is, before the rootstock sap begins to flow and the scion germinates.

What are the precautions for budding fruit trees?

1. Master the time of grafting. Grafting early, the leaf buds of the scion germinate and germinate, the young shoots are tender and weak, the degree of lignification is poor, and it is easy to be damaged by frost in winter. Grafting is late, and the branch epidermis is not easy to separate from the xylem. In the southern part of Hebei Province, it is generally advisable from late July to late August.

2. Avoid rain. To listen to the weather forecast in time, it is generally best to have no heavy rain for 3 to 5 days after grafting.

3. The grafting speed should be fast. Pick down the scion branches, to cut off the leaves in time, leave the petioles, in order to reduce the evaporation of water, it is best to use with the cut, the day can not be used up the scion branches, it is best to put them in a plastic bag in a cool and humid place. The knife used in grafting should be sharp, and the stripped splice code should be grafted in time, which is easy to dehydrate and oxidize after a long time, which affects the survival rate of grafting.

The best time to graft fruit trees is in the spring.

Because the ambient climate in spring is the time when the shoots germinate, they can survive in a very short time after grafting.

Precautions for grafting fruit trees: choose strong and vigorous branches when grafting; When grafting, it is necessary to look at the correct grafting direction, so that the fruit tree can grow more and more luxuriantly, and in the later stage, the fruit will grow bigger and bigger.

Fruit tree refers to a tree with edible fruit, a perennial plant and its rootstock that can provide edible fruits and seeds.

Such as apple trees, pear trees, citrus trees, apricot trees, peach trees, and many more.

Ecological and environmental benefits of fruit trees Fruit trees are generally adaptable, not only can be planted in plains, rivers on both banks, roads, rural gardens and behind the house, but also can grow in sand, hills, tidal flats and other places, select and plant suitable fruit trees, not only increase economic income, but also prevent soil erosion, increase green coverage area, regulate the climate, so as to green, beautify and purify the environment.
