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. [3]

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. [3]

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.
