A. Characteristics of Camellia sinensis
Camellia sinensis belongs to the camellia group of plants. Likewise its flowers are abundant, dignified and elegant. It is not only one of the top ten traditional flowers in China, but also one of the world’s most famous flowers.
B. Camellia is native to China
In the early 7th century AD, Japan introduced camellia from China, to the early 15th century, a large number of varieties of China’s camellia. 1739 Britain first introduced China’s camellia, after the camellia into Europe and the United States. So far, the United States, Britain, Japan, Australia and Italy and other countries in the breeding, breeding and production of camellias developed rapidly. It has entered the stage of industrial production, and interspecies and interspecific hybrids and new varieties are constantly on the market.
C. Biological characteristics of Camellia sinensis
Camellia is native to China. Although it likes warm, moist and semi-shady environment. But it is afraid of high temperature and avoid hot sun.
D.Growth of Camellia
The temperature is 18-25 ℃, golden leaf maiden price, March-September for 13-18 ℃, golden flame hydrangea. September to March of the following year for 10-13 ℃. When the temperature is 12 ℃ above the start of budding, more than 30 ℃ will stop growing. The beginning of flowering temperature is 2 ℃, suitable for the opening of flowers at 10-20 ℃. Camellia’s hardy varieties can withstand -10℃ for a short time, general varieties -3 – 4℃. Summer temperature exceeds 35 ℃, there will be leaf burn phenomenon.
E. Camellia suitable for
Sufficient water, air moist environment, avoid dry . High temperature and dry summer and autumn, should be timely watering or spraying water. Acacia, the relative humidity of the air to 70%-80% is good. Tree rainy season, pay attention to drainage, purple leaf plum, so as not to cause root waterlogging rot.
F. Camellia is a semi-shady plant
Suitable for growth in diffused light, afraid of direct light exposure, seedlings need shade. But long-term overshadowing of camellia growth is not conducive to thin leaves, flowering less. Affect the ornamental value. Adult plants need more light in order to facilitate the formation of flower buds and flowering.
1. Camellia open field cultivation
First of all, choose a deep, loose soil with good drainage. The same pH out 5-6 is most suitable, alkaline soil is not suitable for the growth of camellias. However, potting soil with fertile, loose, slightly acidic loam or humus soil.
2. Propagation methods
Commonly used cuttings, grafting, pressing, seeding and group propagation.
3. Cuttings propagation
In mid-June and around the end of August is most suitable. Select the crown of the external tissue full, leaf integrity, full of leaf buds of the current year half-ripe branches for the plug. 8-10 cm long, leaving 2 leaves at the apex.
4. Camellia cut when
The base as far as possible with a little bit of old branch, inserted easily after the formation of healing tissue, rooting fast. Cut the plug early in the morning, to cut with the plug, inserted into the substrate about 3 cm. Cuttings require the leaves to meet each other, inserted after the finger pressed solid.
5. Camellia to shallow plug is good
This is breathable, healing and rooting fast. The plug bed needs to be shaded and the foliage sprayed daily. Keep it moist and maintain the temperature at 20-25℃.
6. Camellia cuttings after
About 3 weeks to start healing, 6 weeks after rooting. Transplant into pots when the roots are 3-4 cm long. Cuttings using 0.4%-0.5% butyric acid solution dipped in the base of the plug for 2-5 seconds, there is an obvious effect of promoting rooting.
7. Camellia grafting propagation
Commonly used in cuttings rooting difficulties or propagation material less species. To May-June, the new tips have been semi-plastic grafting survival rate is the highest, budding and fast after receiving live.
8. Brick wood to oil tea mainly
October seed harvesting, winter sand storage, the following year in early April sowing. When the seedling grows to 4-5 cm, it can be used for grafting.
9. Using shoot splitting method
Use a blade to cut out the germ portion of the shoot station, in the center of the transverse section of the embryonic axis. Longitudinal splitting a knife along the medulla upward, and then take a section of camellia scion. Also cut the base under the node into a positive shape, and immediately insert the cut scion into the bottom of the brick wood cleft. Align the two sides of the formation layer, tied with cotton thread, and put on a clean plastic pocket. Remove the pockets after about 40 days, about 60 days before budding and tasseling.
G. Camellia crimping propagation
In the rainy season, choose healthy 1-year-old branches, 20 cm from the top. Line ring peeling, side cypress, 1 cm wide. Bound with rotting soil and wrapped with plastic film, about 60 days after rooting. Cut off can be directly potted, high survival rate.
H. Camellia seed propagation
Suitable for single petal or semi-heavy petal varieties. Seeds mature in mid-October, can be sown. It is better to sow shallowly and use vermiculite as substrate. Cover with 6 mm, room temperature 21 ℃. Light for 10 hours every night can promote seed germination. Sprouting starts 15 days after sowing and seedlings reach 8 cm in height within 30 days and are transplanted when seedlings have 2-3 leaves.
I. Cultivation management
Camellia potted plants are commonly used in 15-20 cm pots. Its root system is fragile and care should be taken not to injure the root system when transplanting.
Every spring after flowering or September-October to change the pot, cut off the long branches or dead branches. Replace with fertile rotten leaf soil.
②Camellia likes to be moist
However, the soil should not be too wet, especially for potted plants. Potting soil is too wet easily cause rotten roots. On the contrary, impervious to irrigation, too dry. Flowering pomegranate price, the leaves occur curled. Will also affect the development of flower buds.
③ spring camellia
After changing the pot, do not need to fertilize immediately.
In September, from bud to flowering, apply 1-2 times more phosphorus and potassium fertilizer. (If you have automatic irrigation equipment, you can use more efficient and faster water soluble fertilizer)
⑤ In late summer and early fall
Camellia starts to form flower buds, it is advisable to leave 1-2 flower buds per branch tip. Not too many, so as not to consume nutrients, affecting the main flower buds flowering. When picking buds, pay attention to the position of the leaf buds to maintain the beauty of the plant. At the same time, remove the dried waste buds by hand.
⑥ Post-production treatment
Camellia has a beautiful crown and bright green leaves. The flowers are large and colorful, and the flowering period is long. It blooms on New Year’s Day and Chinese New Year.
⑦ Potted plant decoration
In living rooms, study rooms and balconies, presenting an elegant and pro-Chinese atmosphere. In the courtyard with planting, with flower wall, pavilion in front of the mountain rocks. Red hat moon price, the scenery is naturally pleasant. In the storage and transportation process, to prevent high temperature and air dryness. Otherwise, the buds and flowers are easy to fall off and affect the quality.
