How many years can Camellia oleifera bear fruit after planting?

Camellia oleifera will blossom and bear fruit in about 3-5 years after planting.

Brief introduction of camellia oleifera. (Abel, Latin name for Camellia oleifera. ) Alias: Camellia oleifera, Camellia oleifera, and White Camellia Tea; Camellia oleifera is a small evergreen tree belonging to Theaceae. It is named because its seeds can extract oil (tea oil) for food. Tea oil is a kind of high-quality edible oil with bright color, delicious taste, rich nutrition and storage resistance. It can also be used as lubricating oil and antirust oil in industry. Tea cake is not only a pesticide, but also a fertilizer, which can improve the water storage capacity of farmland and prevent pests in rice fields. Peel is the raw material for extracting tannin extract.

Growth habit

Camellia oleifera likes warmth and is afraid of cold. The annual average temperature 16 ~ 18℃ and the flowering average temperature 12 ~ 13℃ are required. Sudden low temperature or late frost will cause falling flowers and fruits. Sufficient sunshine is needed, otherwise only branches and leaves will grow, resulting in less results and low oil content. Sufficient moisture is needed, and the annual precipitation is generally above 1000 mm, but continuous rainfall at flowering stage affects pollination. It is required to plant in a place with gentle slope and weak erosion, and the requirements for soil are not strict. Generally, it is suitable for acid soil with deep soil layer, not for places with many stones and hard soil.

breeding method

Camellia oleifera is propagated by seeds, cuttings or grafting. In order to maintain the excellent characters of parents, cuttings or grafting are often used to raise seedlings, and then planting and afforestation are carried out. The best afforestation season is from beginning of spring to Beijing-Zhejiang, which is also in June+10 in 5438. Direct seeding afforestation is the best in winter.

1, sowing and seedling raising

Seeding and seedling raising of Camellia oleifera can be carried out in winter and spring, and it is more suitable to use drilling method. Generally, paddy soil, heavy clay and alkaline reactive soil are not suitable for the growth of Camellia oleifera. It is best to choose the distribution area of slightly acidic soil with flat terrain, shelter from the wind and the sun, fertile texture and good water retention and drainage performance. Prepare the seedbed before sowing, apply sufficient base fertilizer, and then cover with a layer of fine fertile soil and a layer of thin grass after sowing to keep the soil moist, so that the seeds can germinate and emerge as soon as possible. When the seeds germinate and are unearthed, it is necessary to uncover the thin grass on cloudy days or in the evening, and weed and loosen the soil in time.

2. Cutting seedling

Camellia oleifera can be cut in spring, autumn and Xia San, but it is best to cut it in summer. Harvest is more suitable for early morning. Branches with lignified leaves, full axillary buds and no pests and diseases should be selected, and then cut into cuttings with a leaf and a bud length of about 4cm. Before cutting, it needs to be treated with ABT rooting powder to promote rooting; When cutting, make sure that the cuttings are upright, the leaves are facing up, and the spacing between plants is about 5cm,15 cm; After the cutting is completed, water it, and pay attention to building a shed for shade.

Generally, the roots of Camellia oleifera will gradually heal within 1 ~ 2 months after cutting, but before rooting, the cuttings should be watered in time to accelerate internal cell division and sprout new roots as soon as possible. After Camellia oleifera takes root, it is necessary to uncover the shade shed in the morning and evening or on cloudy days to increase the light and promote the growth and development of Camellia oleifera.

3. Grafting and seedling raising

There are many methods to graft Camellia oleifera with Camellia oleifera as rootstock, and the most widely used are broken rootstock grafting and continuous rootstock subcutaneous grafting. When grafting with broken rootstock, some vegetative branches of the original crown should be reserved, and 24 scions should be symmetrically grafted on each rootstock according to the size of the rootstock.
