The invention discloses an oil-tea camellia high-yield planting technology. The technology comprises the steps that a, preparation before planting: the growth of oil-tea camellia is poor in an area where soil contains calcareous substances so that the area cannot be selected as a forestry field, soil preparation is conducted in autumn and winter of the first year, and the area is selected according to local conditions based on forestry conditions, operation levels and the like; b, seeding breeding: oil-tea camellia seeds are directly sowed in a seedling bead, culturing is conducted for 1-2 years, bare-rooted seedlings are taken out of a planting field, after the planting field is turned and plowed in early winter, rotted manures are uniformly applied, the rotten manures are broken by rakesto make farmland pieces, rat plaque is prevented when winter sowing is conducted, the seeds are soaked for 2-3 days 25 days before spring sowing, germination acceleration is conducted 18-22 days in asand bed before the seeds are sowed in the planting field, 20,000 seeds are sowed in each mu, which takes up approximately 40 kg of the weight of the seeds, the soil thickness is 1.5-2.0 cm, slight tamping is conducted, and a quick-acting nitrogen fertilizer (0.5%) is applied for once when the height of the seedlings reaches 10 cm. The technology has the advantages that the topdressing of the fertilizer is emphasized to prevent less seeds of oil-tea camellia, and yield improving is achieved.
