2. Illumination: Adult Camellia oleifera with large fruit likes an environment with sufficient light, and it can blossom and bear fruit normally only if it is illuminated for more than 4 hours every day; However, avoiding sun exposure at a young age requires certain shading conditions.
3. Soil: Camellia oleifera likes loose, fertile and slightly acidic soil with good drainage, which can grow in the range of PH 4.5-7, with PH 5-6.5 as the most suitable area, and alkaline soil and places with high groundwater level will not grow well.
4. Seed propagation: sow from 1 1 month to March of the following year. Select the land with flat terrain, convenient transportation, loose soil, convenient irrigation and good drainage as the nursery, and before sowing, carry out detoxification of the soil in the seedbed and apply sufficient base fertilizer; At the same time, the seeds are disinfected and germinated. Strengthen management in time after seedlings are unearthed. Seedlings propagated by seeds can generally bloom in 4-6 years, and produce fruit in 8- 15 years.
5. Cutting propagation: branches of Camellia oleifera 10-year-old with strong growth, big and full fruits and high yield are selected for cutting, Yichun and summer cutting. The seedbed for cutting should be disinfected with soil, and the cuttings should be semi-lignified branches of the same year with complete leaves and full axillary buds. The cutting length is 6-8 cm, with 1-2 leaves left at the top, treated with rooting powder and inserted with cutting. Compacting the soil on the bed surface after inserting, shading the sun and watering it; After that, spray water on the leaves 2-3 times a day to keep the soil moist. In winter, the shade shed can be converted into a plastic shed to prevent frostbite of cutting seedlings.
6. Grafting propagation: Grafting or bud grafting saves materials, is convenient to operate, and has fast propagation speed. As long as the operation technology is skilled, the temperature and humidity are appropriate, and the management is fine, the survival rate can generally reach more than 70%, and the highest can reach 90%. Camellia oleifera Abel or Camellia oleifera Abel can be used as rootstock, and branches of Camellia oleifera Abel with strong growth, good tree shape, tree age of more than 15 years (high yield 10 years), large fruit and high yield can be selected as scions. Grafted seedlings should pay attention to sun protection, waterlogging prevention and cold protection.
Generally, grafted seedlings can bloom in 2 years, bear fruit in 4-5 years, and reach the peak period after 10 years.
