Fruit tree grafting is a method of asexual reproduction that involves attaching branches or buds of an excellent variety of fruit tree to another tree, allowing the two to combine and produce new plants. This technology can maintain the excellent traits of the mother plant while utilizing the advantageous characteristics of the rootstock, such as stress resistance, adaptability, and early fruiting. Here are some fruit tree combinations that can be grafted together: 1. Grafting of fruit trees of the same family and genus
Apples and apples: Grafting can be performed between apple trees to preserve and transmit the characteristics of superior varieties.
Pear to pear: Grafting can also be performed between pear trees to achieve variety improvement and renewal. 2、 Grafting of fruit trees from different families but closely related
Citrus fruit trees: Grafting can be carried out between citrus fruit trees such as grapefruit, orange, and tangerine to produce new varieties or improve the stress resistance of fruit trees.
Peach and Apricot Trees: Although peach and apricot trees belong to different species, they are closely related and can sometimes be grafted. 3、 Cross disciplinary grafting under specific conditions
Pomegranate and Guava: Although pomegranate and guava belong to the families Pomegranaceae and Myrtle, grafting can also be attempted under certain specific conditions. 4、 Grafting methods and precautions
Grafting time: Spring is the main period for fruit tree grafting. At this time, the sap of the rootstock and scion of the fruit tree begins to flow, and the rate of cell division and proliferation accelerates. The wound healing after grafting is fast, and the survival rate is high. Grafting can also be carried out in summer and autumn, but attention should be paid to preventing diseases and pests, and maintaining appropriate temperature and humidity.
Grafting methods: Common grafting methods include cutting, splitting, bud grafting, tongue grafting, belly grafting, etc. The specific choice of method should be determined based on the thickness and size of the rootstock and scion, as well as the purpose of grafting.
Attention: When grafting, keep the interface clean and free of contamination to ensure alignment of the formation layer; After grafting, the interface should be tied tightly in a timely manner to prevent water evaporation and bacterial invasion; After grafting, it is necessary to strengthen management, timely pruning, fertilization, watering, etc., to promote the growth and development of grafted seedlings. 5、 Application and advantages of grafting fruit trees
Preserving excellent varieties: Grafting can preserve and transmit the characteristics of excellent fruit tree varieties, such as size, yield, taste, etc.
Improving adaptability: Grafted fruit trees can acquire the stress resistance of rootstocks, such as cold resistance, drought resistance, salt alkali tolerance, etc., thereby enhancing their adaptability to the environment.
Shortening the growth cycle: Grafting can lead to early fruiting, shorten the growth cycle of fruit trees, and improve economic benefits.
Changing tree shape: Grafting can alter the tree shape of fruit trees, cultivating new varieties that are dwarf, compact, and have high ornamental value.
Fruit tree grafting is an important technique for fruit tree propagation and improvement. When selecting grafted fruit trees, factors such as the genetic relationship between rootstock and scion, grafting time, grafting method, and post grafting management should be fully considered to ensure the success rate of grafting and the growth quality of fruit trees.
