Difference between Camellia oleifera seedlings and grafted seedlings

1, different in nature: Camellia oleifera belongs to Theaceae and is a small evergreen tree, because its seeds can be used to extract oil (tea oil) for food. Seedlings are seedlings that germinate and grow from seeds. Grafted seedlings are seedlings in which branches or buds of a certain variety are grafted on branches or roots of another plant, and the interface is healed.

2. Different characteristics: grafted seedlings can keep the excellent characters of the mother tree, have strong adaptability and early fruiting age, and are widely used in fruit tree cultivation. Seedling cultivation conforms to the natural growth and development law of trees, and the root system is complete. Under the scientific seedling raising technical measures, the seedlings grow neatly and healthily.

3. Different morphological characteristics: Camellia oleifera is oval, oblong or obovate, with a sharp and blunt tip, sometimes tapering or blunt, a wedge-shaped base, a length of 5-7 cm, a width of 2-4 cm, and sometimes longer, with a dark green luster at the top and coarse hair or fur in the midvein. The stand formed by seedlings can cultivate large-diameter timber.

Matters needing attention in grafting seedling raising:

1. After grafting, there are a series of works such as bud wiping, anvil cutting, unbinding, water and fertilizer management, weeding, pest control and so on.

2. When the scion shoots grow to about 2 cm, unbind them, otherwise the normal growth of seedlings will be affected. After that, the pile of soil should be checked in time. If the scion is found to survive and grow buds, the covered soil should be removed to prevent the buds from yellowing because they can't see the sun.

3. When the scion grows new buds, the rootstock above the interface should be cut off to facilitate the growth of the scion. The sprouting strips on the rootstock should be erased in time to avoid consuming nutrients and affecting the growth of grafted seedlings. When the grafted seedlings grow to a height of about 20 cm, a bracket can also be set to protect the scion from being blown off by strong wind.

4. After bud grafting 10 days or so, gently touch the petiole of bud grafting with your fingers. If the petiole falls off when touched, and the color of the leaves remains unchanged, it means that it has been grafted. Generally, the interface of flowers can heal in about 20 days after grafting, and the binding can be lifted after 1 month.
