Planting method of Camellia

Camellia planting methods, camellia originated in our country Yungui plateau, winter without cold, summer without heat, rainfall, air humidity, sunshine soft, no dry wind, soil acid. It is relatively easy to cultivate camellia in the south, but the climate and soil in the north of China are exactly the opposite to those in the south.

Therefore, the cultivation of camellia should first prepare acidic culture soil, it is best to use pine needle soil on the basin, after the annual flower wither pot to change the soil once. Camellia cultivated in Beijing, due to the impact of water quality, will lead to soil salinization, must frequently apply "black alum water", ordinary watering water should be placed a few days later, if found yellow leaves should be immediately irrigated ferrous sulfate solution.

When topdressing should be irrigated sesame sauce residue water and potassium dihydrogen phosphate 1000 times solution. When summer plants appear over-dense branches, long branches, diseased branches and inward branches, they must be cut off to maintain ventilation and light transmission and good tree shape. Camellia cultivation in spring and summer should be appropriate shade, autumn can see more sunshine.

Before flowering, it should be maintained outdoors and ventilated. Water is often sprayed around to improve air humidity, and the basin soil should be dry and wet to create good ventilation conditions for the roots. Winter room temperature shall not be lower than 8℃, nor exceed 16℃. After the flower withers, the flower branch is immediately truncated to promote the axillary bud germination and shoot new branches to prepare for flowering again. If the flower branch is truncated too late, the new branches will not have time to differentiate flower buds, and they will not bloom again. For perennial old plants should be thin cut, some over-dense lateral branches from the base cut off, in order to facilitate ventilation and light transmission, extend the life of the plant, the above is about camellia planting methods.

camellia planting method| Camellia planting technique| The cultivation method of camellia This paper mainly introduces the cultivation method of camellia and camellia cultivation technology and camellia cultivation method. [Overview] Camellia, also known as Camellia, is a camellia plant of Theaceae. Camellia flower posture abundant, dignified and elegant, for China's traditional top ten flowers one. It is also one of the world's famous flowers.

Camellias originated in our country. At the beginning of the 7th century, Japan introduced camellia from China to the beginning of the 15th century. In 1739, camellia was introduced into Britain for the first time, and later camellia was introduced into European and American countries. Up to now, the breeding, cultivation and production of Camellia have developed rapidly in the United States, Britain, Japan, Australia and Italy, and have entered the stage of industrial production.

China has a long history of camellia cultivation. Since the beginning of the Southern Dynasties, camellia has been cultivated. Tang Dynasty camellias as precious flowers and trees cultivation. By the Song Dynasty, camellia cultivation had become very popular. The camellia of Wenzhou in Southern Song Dynasty was introduced to Hangzhou and developed rapidly. In the Ming Dynasty,"History of Flowers" describes and classifies the varieties of camellia. In the Qing Dynasty, camellia cultivation more Sheng, Camellia varieties continue to come out. Since 1949, the cultivation level of camellia has been improved to some extent, and the breeding of varieties has developed. At present, there are more than 300 varieties of camellia in China. Mass production has begun in Zhejiang, Fujian and Jiangsu. At present, it has become the main potted ornamental flowers and trees in the flower market in winter.

[Morphological characteristics and varieties] Camellia is an evergreen broad-leaved shrub. Leaves alternate, leathery, elliptic, margin serrated, dark green. Flowers solitary or 2~3 borne on top of branches or between leaf axils. Flowers single or semidouble. Double petals. Common varieties are single-petaled dawn, ruffled flowers, pure white; race golden light, white flowers, pink lines and sprinkled with fine spots; large flowers golden heart, red flowers, flower diameter 6~7 cm; semi-double petaled category has race Luoyang, red flowers, with white spots; large pine nuts, dark red flowers; drunk Yang Fei, pink flowers; star peach peony, pink flowers. Double petals have white orb, pure white flowers; red hibiscus, oleander red flowers; hibiscus flowers, white flowers, with red lines; flower orb, pink flowers, with irregular red stripes; five cranes holding ball, flowers bright red; flower Buddha tripod, flowers bright red, with a few white spots; red eighteen scholars, red flowers; red Dan, flowers bright red; flower crane Ling, flowers pale red, with white spots. Adolp He Audusson is a breed bred abroad, which has large, deep red flowers and double petals. Alba Plena, large, white, double petals. Berenica Boddy, pale pink flowers, semi-double petals, hardy. Debutante, large flowers, peony type, pale pink. Doncke-larii, red flowers with white marble stripes, semi-double petals. Elegans, large flowers, anemone shaped, rose red with white spots.

Among the hybrid camellias are Donation, large, pink, semi-double flowers; Fragrant Pint, small, peony, dark pink, very fragrant flowers.

[Biological characteristics] Camellia originated in China. Likes warm, humid and semi-shady environments. Fear of heat, avoid the sun.

The optimum temperature for Camellia growth is 18~25℃, 13~18℃ from March to September, and 10~13℃ from September to March of the following year. When the temperature is above 12℃, germination begins, growth stops above 30℃, initial flower temperature is 2℃, and the suitable temperature for flower opening is 10~20℃. The cold-resistant varieties of Camellia can withstand-10℃ for a short time, and the general varieties-3--4℃. Summer temperatures exceed 35 ° C, there will be leaf burns.

Camellia suitable for adequate moisture, humid air environment, bogey dry. High temperature and drought in summer and autumn, should be timely watering or spraying, air relative humidity of 70%~80% is good. Pay attention to drainage in rainy season, so as not to cause root rot by waterlogging.

Camellia is a semi-shade plant, suitable for scattered light growth, fear of direct light exposure, seedlings need shade. However, long-term shade is unfavorable to the growth of camellia, with thin leaves and few flowers, which affects the ornamental value. Adult plants need more light in order to facilitate flower bud formation and flowering.

Open field cultivation, select deep soil layer, loose, good drainage, pH 5~6 is the most suitable, alkaline soil is not suitable for Camellia growth. Potting soil with fertile loose, slightly acidic loam or moldy soil.

[Breeding methods] commonly used cuttage, grafting, layering, sowing and tissue culture.

Cuttage culture: The most suitable month is mid-June and the end of August. Select the half-ripe branches of the current year with full outer tissue of crown, complete leaves and full leaf buds as cuttings, 8~10 cm long, leaving 2 leaves at the apex. Cut, the base as far as possible with a little old branches, easy to form callus after insertion, root fast. Cuttings cut in the morning, to cut with the insertion, insertion matrix about 3 cm, cutting leaves required to each other, inserted with fingers press solid. Shallow insertion is good, so breathable, healing root fast. The cuttings need shade, spray leaves every day, keep moist, maintain the temperature at 20~25℃, heal about 3 weeks after insertion, take root after 6 weeks. When the roots grow 3~4 cm, transplant them into pots. Dip the cuttings base in 0.4%~0.5% IBA solution for 2~5 seconds, which can promote rooting obviously.

Grafting culture: often used for cuttage rooting difficulties or breeding materials less varieties. The highest survival rate of grafting was obtained from May to June when the new shoots were semi-qualitative, and the buds sprouted quickly after grafting. The rootstock is mainly Camellia oleifera, which is collected in October, stored in sand in winter, sown in early April of the following year, and can be used for grafting when the seedlings grow to 4~5 cm. The method of shoot splitting is adopted, the embryo part of the bud stock is cut off with a blade, a knife is vertically split upwards along the pith center in the center of the cross section of the hypocotyl, then a section of the camellia scion is taken, the base part under the section is also cut into a right wedge shape, the cut scion is immediately inserted into the bottom of the crack of the rootstock, the cambium on both sides is aligned, the cotton thread is tied, and a clean plastic bag is sleeved. About 40 days after removal of the pocket, about 60 days to sprout and shoot.

layering culture: plum rainy season selection of robust 1-year-old branches, 20 cm from the top, line ring peeling, 1 cm wide, with rotten leaves tied to plastic film, about 60 days after rooting, cut can be directly potted, high survival rate.

Sowing and breeding: suitable for single or semi-double petal varieties. Seeds mature in mid-October and can be sown. It is better to sow in shallow layer, cover with vermiculite 6mm, room temperature 21℃, light for 10 hours every night, can promote seed germination, germination begins 15 days after sowing, seedling height reaches 8 cm within 30 days, seedling has 2~3 leaves when transplanting.

Tissue culture: The explants are usually seedlings, which are cut into 1 cm long after routine disinfection and inoculated on MS medium supplemented with kinetin 1 mg/L, 6-benzylaminoadenine 1 mg/L and indoleacetic acid 0.1 mg/L. After 4 weeks of culture, only callus is formed, but no bud is formed. After transfer to new medium, individual shoots of 4 cm began to form, which were then immersed in 0.5 mg/L of IBA for 20 minutes and then transferred to 1/2MS medium. Roots grew after 4 weeks. After 8 weeks of growth on long root medium, seedlings were transplanted into pots containing perlite and peat.

[Cultivation Management] Camellia potted plants are commonly used in 15~20 cm pots. Camellia root system is fragile, transplanting should pay attention not to hurt the root system. Potted camellia, every spring after flowering or 9~10 months for pots, cut off long branches or dead branches, replaced with fertile decaying soil. Camellia likes wet, but the soil should not be too wet, especially potted, pot soil too wet easy to cause rotten roots. Conversely, poor irrigation, excessive dryness, and curling of leaves can also affect bud development.

Spring camellias do not need to be fertilized immediately after changing pots. During the vigorous growth period of stems and leaves after summer, fertilize once every half month or use "Huiyou"21-7-7 acid fertilizer. From budding to flowering stage in September, phosphorus and potassium fertilizer should be applied for 1~2 times. In late summer and early autumn, camellia begins to form flower buds. Each root tip should have 1~2 flower buds. It should not be too much, so as not to consume nutrients and affect the flowering of main flower buds. Pay attention to the position of leaf buds when picking buds to keep the plant shape beautiful. At the same time, the dried buds were removed.

[Pest Control] When camellia is cultivated indoors or in greenhouses, if the ventilation is not good, it is vulnerable to red spiders and scale insects. It can be sprayed with 40% omethoate emulsifiable solution 1000 times or washed clean. In plum rain season, the air humidity is high, anthrax damage often occurs, and the same amount of bordeaux mixture or 25% carbendazim WP 1000 times can be sprayed for control.

[Postpartum treatment] Camellia has beautiful crown, bright green leaves, large and colorful flowers, long flowering period, and blossoms on New Year's Day and Spring Festival. Potted plants decorate guest rooms, study rooms and balconies, presenting an elegant and luxurious atmosphere. It is planted in the courtyard, accompanied by flower walls and rocks in front of pavilions, and the scenery is natural and pleasant. In the process of storage and transportation, it is necessary to prevent high temperature and air drying, otherwise buds and flowers will easily fall off and affect quality. How many months do camellias bloom?

Camellia is mainly distributed in China and Japan, China's central and southern provinces have more open cultivation, has 1400 years of cultivation history, many reproductive methods, sexual reproduction and asexual reproduction can be used, of which cuttings and by the use of the most common method, let's take a look at these planting methods of Camellia!

Cuttage propagation of Camellia sinensis

This method is the most convenient, cutting time in September is the most appropriate, spring can also be, select good growth, semi-lignification branches, remove the base leaves, retain the upper 3 leaves, cut into oblique mouth with a sharp knife, immediately immerse the incision in 200-500ppm indole butyric acid for 5-15 minutes, dry after inserting sand basin or vermiculite basin, after planting watering wound healing for about 40 days, rooting for about 60 days. Rooting of cuttings treated with hormone was 2-3 months earlier than that without hormone. Rooting in vermiculite beds is much faster than in sand beds.

THE NEEDLING PROPAGATION OF CAMELIA

Select appropriate varieties such as tea cup tea or Camellia oleifera as rootstock, close to the precious camellia, close to the time is generally between Qingming Festival to Mid-Autumn Festival, first plant the rootstock in the flowerpot, cut off about half of the parts to be combined with a knife, the incision should be smooth, then make the cut surfaces of both sides closely fit, wrap with plastic film, sprinkle the rootstock twice a day, heal after 60 days, then cut and plant, and place it under the shade of trees to avoid direct sunlight. In February of the following year, the tail of the rootstock was cut off with a knife and planted again.

leaf insertion propagation of camellia

Camellia propagation generally uses branch cuttings propagation, but some valuable varieties due to the restriction of branch sources, or considering that the material will affect its tree shape, so also use leaf insertion method. With mountain mud as cuttage substrate, can be mixed into 1/3 of the river sand, to facilitate ventilation drainage, substrate in the pot, and then pot insertion. Leaf cutting is best carried out in rainy season, taking annual leaves as leaf cutting materials, too old is not easy to root, too tender is easy to rot. Insert about 2 cm into the soil, compact the soil after insertion, irrigate enough water, and then put it in a cool and ventilated place. Generally 3 months can root, the following spring can sprout and shoot.

High cutting propagation of camellia

The biggest characteristic of the high-altitude cutting method is that it can give new life to all the weak branches that should be pruned off on camellia. And this method has high survival rate, rapid rejuvenation and early flowering. The thin branches that need to be trimmed are girdled at appropriate positions,(generally the upper part can be reserved for 15-25 cm branches), the girdling length can be between 5-8 mm, the plastic film of appropriate size is bound, and the sterilized peat soil or rotten leaf soil is added to the film. After 7-10 days, the lower part of the plastic film is girdled for 5-8 mm, which is called double girdling and high insertion method.

Tree grafting propagation of camellia

Camellia is a plant that is difficult to survive. There are many ways to reproduce camellia. Grafting is the most commonly used. Grafting has many advantages. It can maintain the excellent characteristics of the variety, accelerate the growth of the plant, make it quickly shape, and can produce on a large scale. It saves spikes, especially for rare varieties with few spikes. Grafting camellia technology: The best grafting time was from June to July, when the leaves of scion of Camellia were unfolded and the temperature was high, the grafting wound healed quickly and the survival rate was high. Grafting method is the use of branch grafting method in the cutting method, due to the grafting of higher parts, often known as "high grafting head."

How many months do camellias bloom?

The camellia flowers bloom continuously from the end of September to the beginning of May due to different varieties. In late autumn, winter and early spring, it presents a vibrant scene. Camellia has two shoots a year, the first is spring shoots, starting from March to April; summer shoots bloom from July to September.
