1) seed selection

When picking Camellia oleifera seeds, we should choose good slices, plants, fruits and seeds, and choose fresh and high-quality seeds with large and full seeds, dark brown seed shells, no diseased spots and luster. Pay attention to the storage method of seeds: after the tea fruits are harvested, they should not be piled and soaked, but should be thinly spread in a ventilated and dry place to naturally crack and thresh, and the seeds can be stored in a cool place indoors. Generally, wet sand is mostly stored on the ground, and kiln storage can also be used.

2) Prepare the soil carefully

Soil preparation should be carried out in summer and autumn one year before afforestation. In mountainous areas, mountain cutting and mountain refining should be carried out one year before soil preparation. Land preparation methods include comprehensive land preparation, strip land preparation, block land preparation, etc. , and appropriate soil preparation methods should be adopted according to local conditions.

3) Prepare to plow the fields

In the place suitable for planting, holes should be opened at the row spacing of 2× 3.3m for cultivation. First, the live broadcast place is arranged as a 40×40cm platform, and then a long hole with the depth of 10- 15 cm is opened in the platform to facilitate water storage and drought prevention.

4) On demand

Put three seeds into a small hole in the platform and scatter them into triangles. Pay attention to the fact that the seeds must stick to the solid soil, which is beneficial for the seeds to absorb water and germinate. After sowing, the soil should be shallow and thin to prevent human and animal injuries and water evaporation. In addition, in order to prevent animals and mice from being harmed, seeds can be mixed with drugs.

5) management

After the seeds germinate to a height of 20 cm, the seedlings can be simplified, leaving the strongest of the three seedlings, removing the other two or planting them in other places for later use.

Second, the growth conditions

Camellia oleifera likes warm and humid climate and is the main tree species to transform red soil. Its growth and development process is divided into five parts: new bud, flower bud, flowering, fruiting and root regeneration. Camellia oleifera has strong adaptability to soil, and is resistant to poverty and drought, but it requires high temperature, relative humidity, annual average rainfall and sunshine time. Plants under superior conditions can still bear fruit after 150 years, which is more vigorous than our human vitality.

Third, the distribution characteristics

The northern boundary of Camellia oleifera distribution area is in Huaihe-Qinling line; The southern border is roughly near the Tropic of Cancer; The eastern border is the southeast coast and Taiwan Province Province; The western border is the Nujiang River Basin in Yunnan and the eastern edge of the Qinghai-Tibet Plateau. The vertical distribution in the eastern region is generally below 800 meters above sea level, and the western region can reach 2000 meters above sea level.
