Orange tree grafting method

1. Abdominal grafting method

Make the incision 10-15 cm from the ground, and choose the smooth side of the southeast direction to make the incision. Place the scion into the incision. The cortex of the scion should be aligned with the cortex of the incision. The lower end of the short shaved surface of the scion should be in contact with the bottom of the incision of the stock. Wrap the scion and the stock tightly with a film tape. During abdominal grafting in spring or May-June, the exposed buds can be bandaged; during grafting in autumn, the scions should be completely wrapped in film.

2. Bud grafting

Bud grafting takes place in August-September. Choose strong, current-year branches of good varieties as seed strips for crimping. The original trees can be pruned appropriately and grafted. Tokihara trees can be grafted in many places. Branch grafting is carried out in early spring before budding, and strong seed strips are also selected, but it is best to select seed strips of the same thickness as the grafted tree. Just cut the bottom of the seed strips into a pointed shape for grafting.

Notes on grafting:

1. Choose rootstocks and scions with strong affinity

The affinity refers to the rootstock and scion. The ability of the scion to heal after grafting. Generally speaking, the closer the genetic relationship, the stronger the affinity, and the higher the grafting survival rate.

2. Choose rootstocks and scions with strong vitality

Viability is related to the nutrients accumulated in the vegetative organs of the rootstock and scion. The more nutrients accumulated in the vegetative organs, the more substantial the development will be. Therefore, before grafting, water and fertilizer management of the rootstock should be strengthened to allow it to accumulate more nutrients, and mature branches with full buds should be selected as scions.

3. Choose the best grafting time

Generally, branch grafting should be carried out in early spring before the fruit tree germinates, because at this time the rootstock and scion tissues are full, and the temperature and humidity are also conducive to the formation of Vigorous division of layers accelerates wound healing. Bud grafting should be carried out during the slow growth period so that the graft can survive and germinate into seedlings in the second spring.

4. Use plant hormones to promote healing

The scion should be treated with plant hormones before grafting. For example, soaking in 200-300PPM naphthylacetic acid for 6-8 hours can promote the formation of cambium layer. activity, thereby promoting wound healing and improving graft survival rate.

5. Standardize technical operations. When grafting, the action should be rapid, and the rootstock and scion should be trimmed strictly according to the technology. The joint surface should be smooth so that the cambium layers of the rootstock and scion are closely connected. The binding should be moderately tight and untied in a timely manner. tie.
