Fruit tree grafting skills, many people don t know why they use wild rootstocks for grafting

Wild rootstocks are resistant and vigorous.

Grafting can pass on the advantages of varieties with disease resistance to other varieties, thereby improving the disease resistance of fruit trees and reducing the occurrence of diseases.

Fruit tree grafting is a traditional method of fruit tree propagation, which is widely used in fruit tree planting. So, why do fruit trees need to be grafted? This article will uncover the mystery of fruit tree grafting.

1.Scion grafting.

Fruit tree grafting refers to the process of grafting the buds, branches, flowers, and fruits of different fruit tree varieties onto the same fruit tree, making it a whole. The grafted fruit trees have stronger vitality and resistance to stress, and can improve the yield and quality of fruits.

Bud grafting is the grafting of a bud of the desired variety onto the branch of another fruit tree, this method is suitable for the case of the fruit tree with an older age and a thicker trunk.

1.Improve the quality of fruit trees.

Anvil grafting is to graft the buds or branches of the desired variety to the dead root anvil of another fruit tree, this method is suitable for the older age of the fruit tree, the trunk is thicker and hungry, and it is also a grafting method that is often used in defeat.

Grafting can make fruit trees obtain a better growth environment, improve fruit yield, and at the same time, it can also shorten the growth cycle of fruit trees, so that fruit trees can enter the fruiting period faster.

Fruit tree grafting is a traditional way of fruit tree propagation, through grafting, it can improve the quality of fruit trees, increase the yield of fruit trees, and enhance the disease resistance of fruit trees. Grafting methods include scion grafting, bud grafting, root anvil grafting, etc. Fruit tree grafting is an indispensable technology in fruit tree cultivation.

Bud grafting is to graft the buds of the desired variety onto the branches of another fruit tree, which is suitable for the older age of the fruit tree and the thicker trunk.

2.Increase fruit tree yields.

3.Enhance disease resistance of fruit trees.

It is necessary to choose the right time, to choose the right technique, to master the key points of action, to choose relatively mature production conditions, to pay attention to temperature, to have a particularly strong theoretical foundation, to choose the right production conditions, to choose a robust mother tree.

The grafting of fruit trees requires scientific and technical mastery and grafting, and the right time should be chosen. The grafting method of different fruit trees is different, and it is necessary to choose the branches that are suitable for grafting.

1. T-shaped budding.

2. Ordinary bud grafting.

3. Grafting of bark.

4. Ordinary grafting.

For the grafting of fruit trees, we must grasp the development of grafts, build more branches and buds without scion, and grasp the time and season of grafting.

1. Fruit trees do not have to be grafted.

2. There are two situations of grafting, one is the need for fruit tree seedlings, and the other is the improvement of the original varieties.

3. Seedling grafting is because the seedlings born by sowing seeds cannot maintain the excellent characteristics of the original quality. The improvement of grafting is due to the need to improve the economic value of fruit trees, such as improving the sense of pin and nutrition of fruits, and enhancing the ability of fruit trees to enhance cold resistance, drought resistance, and resistance to pests and diseases. Grafting is divided into two categories: branch grafting and bud grafting, and the former is suitable for spring and autumn, especially in spring, where the survival rate is higher.

The latter is preferably carried out in the summer.

Fruit tree grafting is generally divided into spring grafting and summer grafting. In spring, it is mainly grafted with branches, cuttings, and plugging, and in summer, it is mainly bud grafting, and spring is a good time for fruit tree grafting to improve the survival rate of grafting. Hurry up, the grafting time is early, the sap does not flow, and the leaf buds of the scion do not germinate, so it is not easy to survive after grafting.

Grafting is late, the branches are long leaves, the amount of water evaporation is large, and the grafting is not easy to survive.

The spring connection is generally around the "spring equinox", and the summer connection is generally from late July to late August. Choose strong shoots that are strong, full of leaf buds, and have strong vitality that are easy to survive. Avoid rainy and windy weather.

You should listen to the weather forecast in time and choose a hot and sunny day. It is better not to rain heavily for 3 to 5 days after grafting. Scion sealing wax, in order to reduce the evaporation of scion moisture, scion sealing wax should be treated by melting industrial paraffin.

When the wax temperature reaches 95 102, one end of the scion shoot is quickly immersed in the wax solution, and then the other end is quickly immersed.

The grafting speed should be fast, the cable tie should be tight, and the branches should be pruned and used at any time. The scion branches that cannot be used up on the day should be placed in a plastic bag and placed in a cool, damp place. The grafting knife should be sharp, the peeling surface should be smooth, and the grafting should be timely.

After grafting, it is easy to dehydrate and oxidize, which affects the survival rate of grafting. Varieties of the same family and genus have the same thickness and the best quality, which can improve the survival rate. If the intermediate rootstock is used as the base rootstock and the Pengkan is used as the intermediate rootstock, the high connectivity of the navel orange will manifest itself as connective swelling, yellowing and poor fruit.

The root system of grafted rootstock is developed, the growth is vigorous, and there are no diseases and pests; The selection of scion should not only ensure vigorous growth and no pests and diseases, but also pay attention to the selection of large buds and strong buds. The key to grafting fruit trees is the formation of callus, including temperature, humidity, air, and dark environments. The temperature is high in summer, and it is easy to burn the buds, but it is not easy to lignify in autumn.

T-bud grafting can be used for peach, pear, apricot, citrus and other tree species that are easy to survive after grafting; The method of grafting xylem buds can improve the survival rate of fruit trees.

Grafting methods for fruit trees: T-shaped bud grafting, woody bud grafting, and tongue grafting.

Budding: Make a T-shaped opening on the rootstock and insert the bud point into the incision.

2.Bud grafting is to cut a bud from a branch, with or without xylem, insert it into the incision on the rootstock, and tie it to make it close to heal. It is advisable to choose the slow growth period of budding, so that the cambium cells are still active and the budding tissue is also enriched.

3.There are two methods: cuttings and single bud grafting. Among them, the grafting "wedge" cutting method is the same as the splitting method, the difference is that the "wedge" is short and steep, the longer slope is about 2 cm, and the short slope is 1 cm.

The longer bevel is facing the xylem of the rootstock. The general way of opening the jack joint rootstock is a "T" shaped opening. There is also a "one point and one horizontal" rootstock opening method for cuttings, and a method of making a longitudinal opening at the cutting end of the rootstock.

After plugging, it is tied with the splitting method, and the single bud grafted should expose the bud eye. Leave 1-3 buds in the grafting strip, cut off, cut the lower part into one side to peel, flatten, one side cut into an inclined plane, peel and flatten that face the rootstock, so that the skin to the skin, this is the key, if it is not as thick, as long as more than half of the skin is closed, it can be successful, the cutting surface must be smooth, and the skin must be tight.

We should choose the right time for grafting, pay attention to the method of grafting, and understand the scientific grafting method, so as to ensure the survival rate of fruit trees. When grafting, disinfect in advance, control the temperature of grafting, learn grafting skills, pay attention to the inspection after grafting, and understand the method of grafting, after understanding these skills, you can ensure the survival rate of fruit trees.

You should understand the skills of grafting, prepare for grafting, and pay attention to disinfection in advance, so as to ensure the survival rate of fruit trees. When grafting, it is necessary to learn experience, understand the method of grafting, pay attention to management, pay attention to the maintenance after grafting, and avoid pests and diseases, so as to ensure the survival rate of fruit trees.

It is necessary to pay attention to the time of grafting, generally speaking, spring will be chosen for grafting, the branches should be selected for grafting, the rootstock should be cut when it is 8 cm from the ground, and then wax should be applied to prevent dry cracking.

Different varieties of grafting methods are different, we must pay attention to the surrounding temperature, when grafting, we must maintain the stability of temperature, pay attention to water and fertilizer management.

Be sure to graft in the spring and avoid rain. It is better to choose the one with the same account attributes. Strong shoots should be selected for grafting. Be sure to apply fertilizer in a timely manner.
