Management techniques after grafting of Loquat

Fruit tree grafting needs to master certain techniques, loquat is not listed, grafting time and methods are wrong, will lead to grafting failure, in addition, grafting management does not keep up, grafting failure will often occur. So how to manage loquat after grafting? Come and have a look with the editor.

1. Check the survival rate

Generally, after 20-30 days of grafting, you can tell whether the scion is alive or not, and you can check it from the state of the buds and petioles. If the buds are fresh and the petiole is touched, it means that they have survived. For example, the buds are withered, the color is scorched, and the buds have dried up. Some scions are blackened at the top, indicating that they have not been grafted, and those who have not survived should be regrafted in time.

2. Break the membrane and show the bud

When the grafting bud begins to germinate, use the knife tip to carefully pick the grafting film that hinders the grafting bud germination, for example, the grafting bud has survived. After unlocking the film strip for 7-10 days, the diameter of the rootstock at the top of the grafting bud is 4/5 in diameter and twisted from the cutting place, so that 1/5 of the rootstock bark is connected to the stem, and the upper and lower water and nutrients are interconnected. When the grafted buds germinate and pull out the secondary shoots, there are at least 4-5 mature leaves on them, and all the branches and leaves on the rootstock are cut off after the new shoots stop growing.

3. Sprouting post

The management center after grafting is to protect the scion and promote its germination. The rootstock buds germinated at the lower part of the interface should be erased in time to reduce unnecessary nutrient consumption, and the rootstock should be cut off 1 cm above the interface after the new shoot is ripe. New shoots and young leaves are large and easily broken by the wind, so they should be inserted into pillars and fastened with thin film or other ropes.

4. Fertilizer and water management

After the spring shoot is ripe, it is necessary to apply thin fertilizer, ditch fertilization, fertilizer on the original crown dripping line, cause fine roots, timely irrigation in drought, and timely drainage and waterproofing in the rainy season. In addition, we should also pay attention to strengthen the prevention and control of diseases and insect pests, aphids can be controlled by dichlorvos spray, leaf spot can be controlled by methyl topiramate.
