1, cutting
In the rainy season from May to June, select young mother trees and cut annual branches from the top, about 10cm long. Remove the lower blades, flatten the lower nodes with blades, leave 1 terminal buds and 2 ~ 3 blades at the top, and insert them into river sand or gravel medium with the insertion depth of 1/3-2/3.
After transplanting, cover the grass curtain for shade, strengthen foliar spraying, keep the air humidity of the transplanting bed and promote rooting. In order to improve the survival rate of cuttings, cuttings can be soaked in 50- 100ppm ABT rooting powder solution for 8- 12 hours. ?
2. Transplantation method
Selecting robust seedlings or camellia varieties which are easy to survive by cutting as rootstocks, cutting at a distance of 4-5cm from the ground diameter, splitting through pith to a depth of about 1.5cm, using 1-2-year-old branches as scions, leaving 1-2 leaves on the upper part of the scion, cutting the lower part into wedges, and inserting into the split cracks of the rootstocks, so that the cambium on both sides can be closely adhered.
Then put a plastic bag on the scion, and tie it with a belt below, but not too tight, so that water drops can form in the bag and drip on the rootstock. Then add a packaging paper bag outside the plastic bag to block the direct sunlight.
3. Bud cuttings
Take each bud node as a section, keep a leaf, about 1.5cm long, obliquely cut the lower part, and then insert it into the culture medium, the depth of which shall be subject to covering the branches. This method can make full use of branches and is suitable for mass propagation.
Conservation and management
1, soil
Soil is the growth foundation of potted camellia, because the root system of camellia depends on the growth and development of soil, and the water and nutrients needed for camellia life activities are mainly absorbed from the soil. Camellia likes mountain red (yellow) loam with acid, high humus content and loose ventilation, and its pH value is between 5 and 6.5. Alkaline soil or cohesive soil cannot be used as the substrate for potted camellia.
2. Lighting equipment
Camellia needs proper illumination, but it is afraid of direct sunlight at high temperature. In spring and late autumn, camellia should be moved to the sunny balcony or ground to receive full-day illumination, so as to promote the growth and development of plants and promote the differentiation of flower buds and robust buds.
3. Temperature
Temperature is one of the important conditions for the growth of camellia. Camellia likes warmth. The optimum growth temperature is 65 08℃ ~ 25℃ and the relative humidity is 60 %~ 65%.
water
Camellia has many leaves, large leaf area and fast transpiration. Camellia likes humid climate and moist soil.
5, fertilization
Camellia is a fertilizer-loving flower. Because of its strong trees, many leaves and long flowering period, it needs more fertilizer.
6. Ventilation equipment
Camellia likes to grow in an environment with moderate air flow, and the breeze is the best. It likes the water vapor brought by the southeast wind, but it is afraid of the northwest wind and strong wind, which makes the water evaporate too fast, the supply and demand of camellia lose balance, the leaves are easily damaged, and the phenomenon of falling buds and flowers appears.
Extended data
American scarlet has bowl petals, single petals or double petals, and there are many rare varieties such as eighteen bachelors and hexagonal scarlet, which can be planted by cutting and docking. Health-preserving scented tea made of camellia has the curative effect of treating hemoptysis and cough. Camellia is cherished by the world horticultural community because of its beautiful plant shape, bright green leaves and colorful flowers. Its flower language is lovely, humble and cautious.
I like a warm and humid climate, neither cold nor hot is suitable. It requires living in acidic soil in semi-cloudy environment, fearing drought and avoiding water accumulation.
