The latest course of cultivation techniques of Camellia oleifera

Camellia oleifera, also known as Huangzhongmu, Brazilian Campanula, Yibei, etc., is a deciduous plant of the genus Campanulaceae. It is often used as an excellent street tree, and can also be planted in courtyards, campuses, residential areas and other places with golden and bright flowers. It is suitable for roadside and waterfront cultivation in parks and green spaces. Let's take a look at the cultivation techniques of Camellia oleifera.

Growth habits of Platycladus orientalis

Suzuki is the national flower of Brazil, originated in Mexico, Central America, South America and other places. The sex is fond of high temperature, and the suitable temperature for fertility is 20-30 ℃. Winter needs to be warm and sheltered from the wind. The northern part of South China is cold, rainy and humid in winter, so we should pay attention to cold damage. The sandy loam rich in organic matter is the best cultivated soil. Drainage and sunshine should be good.

Propagation method of Suzuki in Yellow Flower

Camellia oleifera is only suitable for cultivation in tropical and subtropical areas in China, which can be propagated by sowing, cutting or high pressure, but mainly by sowing, with spring and autumn as the suitable time. The cultivated soil is the best in soil rich in organic matter or sandy soil. The sex is fond of high temperature, and the suitable temperature for childbearing is 23-30 ℃.

Cultivation techniques of Yellow Flower Wind Suzuki

1. Temperature environment: the suitable temperature for the growth of Suzuki is 23-30 ℃, and it is not cold-resistant. Strong light is also required in the seedling stage, especially when sowing and raising seedlings in the greenhouse environment, it is very easy to cause weak seedling growth and quenching disease due to lack of light and ventilation. Therefore, after the seeds germinate and the true leaves unfold, it is necessary to ensure that the shading rate of the growth environment does not exceed 50%, while maintaining adequate ventilation.

2. Soil fertilization: the nursery for cultivating large seedlings of Camellia oleifera should choose places with loose and fertile soil, good irrigation and drainage, plan and arrange the ditches for drainage and irrigation, and plant about 3000 plants per mu. When planting, 250g compound fertilizer or 1kg organic fertilizer per hole should be used as base fertilizer, and the base fertilizer should be confiscated and mixed with the soil before planting seedlings. When planting seedlings, it is necessary to remove the seedling bag and plant it steadily.

3. Plant binding: Suzuki grows fast at seedling stage, the trunk is soft, easy to lodge and sprout, and the natural plant type is often not good. In order to obtain an upright plant type, about 2 meters of supporting bamboo should be erected next to the seedling when the seedling height is 30cm to 50cm after planting, and the seedling should be tied up for each height of 50cm.

4. Pruning and shaping: regular pruning and shaping is carried out during the growth of Suzuki, cutting off low meristematic lateral branches, pruning and shaping should be carried out after falling leaves in winter, and diseased branches, dead branches and even lateral branches should be cut off, so as to keep the trunk growing straight. When the trunk is 1.8 cm high, the top branches are retained to form a crown. After 3 ~ 4 years of field cultivation, the plant can be planted in the nursery when the plant is more than 3 m high and the diameter is 4 cm ~ 6 cm.

5. Disease and pest control: coffee wrinkled longicorn beetles are often harmed in Camellia oleifera. Cashew trees are surveyed three times a year. When a damaged tree is found, the bark of the damaged tree is cut open with a sharp knife, and the longicorn beetle larvae are taken out. After the wound is dry, the soil is cultivated to promote the growth of adventitious roots and to restore the growth potential of the plant. When pests are found, an injection syringe can be used to inject pesticides into the tunnel to kill the larvae.
