Introduction to Culture Environment and methods of Camellia

Camellia is beautiful in shape, rich and shiny leaves, beautiful and colorful flowers. It is one of the world famous flowers. It is also the provincial flower of Yunnan Province, the city flower of Chongqing City and Ningbo City of Zhejiang Province, the state flower of Dali Bai Autonomous Prefecture of Yunnan Province. The cultivation of Camellia sinensis has entered the court as early as Sui and Tang Dynasties. So how should camellias be cultivated? Here's how to share the camellia culture:

Culture environment of camellia

Camellia growth temperature between 15~32℃, the requirements of a certain temperature difference, environmental humidity above 60%, most varieties can withstand-8℃ low temperature (natural winter, cloud tea slightly less cold), in the south of the Huaihe River generally can be natural winter. Camellia cultivation soil to acid, and require better permeability. To facilitate root hair growth, usually available peat, sawn rot, red soil, humus soil, or more mixed substrate cultivation. Camellia requirements than cuckoo light, spring and autumn three seasons can not shade, summer available 50% shading treatment.

1. Light and temperature: Camellia is a long-day plant. Flower buds can only form in a 12-hour environment. The optimum growth temperature is 18~25℃, the optimum flowering temperature is 10~20℃, and the leaves will be burned if the temperature is higher than 35℃. Not cold, winter should enter the room, the temperature should be maintained at 3~5℃, but also can withstand a short time of-10℃ low temperature, but not for a long time more than 16℃, otherwise it will promote germination, causing deciduous. Growth period should be placed in a semi-shady environment, should not receive too strong direct sunlight. Especially in summer and autumn, shade should be carried out, or shade should be placed under trees.

2. Watering and fertilization: Camellia has higher requirements for fertilizer and water, and neutral and alkaline loam are unfavorable for its growth. In particular, the north should pay attention to the alkaline water after acidification treatment before watering flowers, the specific method is to store tap water for 2 days, so that chlorine in the water volatilizes, and then add appropriate amount of ferrous sulfate (accounting for about 0.5% of water). Water quantity can't be too big, otherwise easy rot root. Basin soil can not be dry, otherwise easy to make roots shrink due to water loss, in order to maintain the basin soil and the surrounding environment moist is appropriate. Do not spray water during flowering. Fertilization with thin alum fertilizer water is good, avoid applying thick fertilizer. Generally, after germination in spring, thin fertilizer is applied once every 17 days, phosphorus and potassium fertilizer are applied in summer, fertilizer can be stopped for about 1 month in early autumn, alum fertilizer is applied again before flowering, and available phosphorus and potassium fertilizer are applied again when flowering, so that flowers are big and colorful, and flowering is long.

Breeding method of Camellia sinensis

Camellia propagation methods are many, sexual reproduction and asexual reproduction can be used, of which cuttings and by the most common method.

1, cuttage propagation: cuttage propagation is the most simple, cuttage time in September is the most appropriate, spring can also be. Select well-grown, semi-lignified branches, remove the basal leaves, keep the upper 3 leaves, cut into oblique openings with a sharp knife, immediately immerse the incision in 200 - 500ppm indolebutyric acid for 5 - 15 minutes, dry it in the sun, insert it into a sand basin or vermiculite basin, water it for about 40 days after insertion, and heal the wound, and root in 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.

2. Breeding by grafting: Select appropriate varieties such as tea cup tea or Camellia oleifera as rootstock, and rely on precious camellia. The time of contact is generally between Ching Ming Festival and Mid Autumn Festival. First, plant the rootstock in a flowerpot, cut off about half of the parts to be combined with a knife, smooth the incision, and then make the sections of both sides closely fit, wrap them with plastic film, drench the rootstock twice a day, and heal after 60 days. Then cut planting, and placed in the shade, avoid direct sunlight. In February of the following year, the tail of the rootstock was cut off with a knife and planted again.

3, leaf cutting propagation: leaf cutting method Camellia propagation generally adopts branch cutting propagation, but some valuable varieties due to the restriction of branch source, or considering that the material will affect its tree shape, so also adopt leaf cutting 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.

4. High insertion propagation: The biggest feature of the high-altitude cutting method is that it can give new life to all the weak branches that should have been pruned off on the camellia. And this method has high survival rate, rapid rejuvenation and early flowering. The method is as follows: the thin branches to be trimmed are girdled at appropriate positions,(generally the upper part can be retained as 15~25 cm branches), the girdling length can be between 5~8 mm, plastic films of appropriate size are bound, sterilized peat soil or rotting leaf soil is added into the films, and after 7~10 days, girdling 5~8 mm is carried out at the lower part of the plastic films, which is called double girdling and high insertion method.

5. Tree grafting propagation: Camellia is a plant that is difficult to survive. There are many ways to reproduce Camellia, among which grafting is the most commonly used. Grafting propagation camellia has many advantages: can maintain the excellent characteristics of varieties; can speed up plant growth, so that its rapid formation, and large-scale production; save ear, especially for those rare varieties with few ear sources, especially important; Camellia tree grafting camellia technology is as follows.

① Grafting time: Grafting time should be between June and July, at this time, the leaves of new shoots of Camellia scion have been unfolded, and the temperature is higher, the grafting wound heals quickly and the survival rate is high.

② Grafting method: Use the cutting method in the branch grafting method. Because of the higher position of grafting, we often call it "high grafting".

After reading the cultivation environment and breeding methods of tea, please follow Xiaobian to take a look at the cultivation methods of camellia!

Cultivation method of camellia

Camellia usually to use neutral or acidic surface water irrigation, watering to master see dry see wet, dry and then water, water to pour thoroughly, but pay attention not to dry. Generally, water should be properly withheld before budding at the end of spring shoots to facilitate the transformation to reproductive growth, and water should not be cut off before flowering.

1. Place: Camellia should be placed in a warm, humid, ventilated and translucent place. Spring should have sufficient light, summer should pay attention to shade, avoid direct sunlight and the west sun, if placed on the balcony, often a careless, will be sunburned.

2. Watering: The cultivation of Camellia bonsai should keep the soil moist, but it should not be too wet to prevent dry and wet. Generally in spring can be properly watered, in order to facilitate germination and shoot; summer insist on early and late watering, it is best to spray leaf water, so that the leaves are wet, do not use rapid water direct irrigation, full irrigation, not hot water, avoid high temperature around noon watering; autumn watering to appropriate; winter should be watered around noon, can spray water every two or three days.

3. Fertilization: Camellia likes fertilizer. When putting on the pot, it is necessary to pay attention to putting base fertilizer in the pot soil, mainly phosphorus and potassium fertilizer. The fertilizer applied includes decomposed bone meal, hair, chicken feather, chaff ash, poultry manure and calcium superphosphate. It is not advisable to fertilize too much at ordinary times. Generally, 2~3 times of thin fertilizer should be applied between 4 and 5 months after flowering, and a slightly thicker fertilizer can be applied once in November in autumn. Fertilizer should pay attention to the proportion of phosphorus slightly larger, in order to promote flower color Yan.

4, pruning: Camellia growth is slow, should not be over-pruned, generally affect the tree's long branches and pest branches, weak branches can be cut off. If there are too many buds on each branch, only 1~2 flowers can be left, and a certain distance should be maintained, and the rest should be picked early to avoid consuming nutrients. In addition, it is necessary to pick flowers that are close to withering in time, which can also reduce nutrient consumption, so as to facilitate the healthy growth of plants and the formation of new flower buds.

5, pot turning: Camellia bonsai can be turned over once every 1~2 years, the new pot should be larger than the old pot No. 1, in order to facilitate the development of root system. The best time to turn pots is in April in spring or autumn. Combined with soil replacement, properly remove some hardened old soil, replace it with fertile and loose new soil, and combine with base fertilizer.

6, pests and diseases: Camellia diseases mainly black mold, anthracnose, etc., can be sprayed with 0.5 degrees Bordeaux mixture for control. Insect pests are mainly tea shoot moth, control methods can cut off insect shoots, generally in April to June for appropriate.

7, flowering: because camellia is not cold-resistant, delayed flowering is not commonly used. Flowering is generally controlled by variety selection, temperature control and hormone treatment. To make camellia "eleven" flowering, can be in mid-July or early August with a brush dipped in 0.1% of the gibberellin, point painted on the bud, painted once every 3 days, fertilizer water normal management. September to see the bud growth to decide whether to apply buds, if it is estimated that "eleven" flowering is not safe, can increase the number of buds, increase the amount of fertilizer, promote the rapid growth of buds, so that "eleven" see flowers.

Winter Management of Potted Camellia

1, anti-freezing warm: When the temperature drops below 0 degrees Celsius, the potted camellia will be moved to the outdoor sunny warm shelter, or placed in a plastic shed sealed on three sides and sunny on one side. It can also be placed indoors, but it is required that the place where it is placed is well illuminated and ventilated. In case of cold frost weather should pay attention to keep warm, in the sudden cooling before the best outdoor camellia moved indoors. If it is placed outdoors, it should be covered with plastic film, newspaper or cloth at night.

2, water and fertilizer management: camellia likes warm, humid environment, afraid of ponding. Watering before flowering should master the principle that the pot soil is not dry and not watered, and the watering is thoroughly watered.

3, winter every 3 to 5 days with water temperature and room temperature similar to spray foliage 1 time to increase humidity and clean foliar dust. The watering amount in flowering period should be dry and wet in pot soil, and the suitable watering time is noon on a sunny day. Winter is the flower bud expansion period of Camellia, spraying 0.1% to 0.3% potassium dihydrogen phosphate solution once a month in combination with foliar spray, or applying thin liquid fertilizer based on phosphorus and potassium (fertilizer water ratio is 1:4) once a month.

4. Do not spray water on the flowers when watering, otherwise it will cause the flowers to rot and shorten the flowering period. Picked off the flowers in time after they had withered.

The cultivation method of camellia camellia cultivation methods and precautions

Camellia is a camellia attribute plant of Theaceae, which likes warm and humid environment. Among the many flower plants, camellia has a longer flowering period, which can bloom from October to May of the following year. Camellia flower colors are red, purple, white, yellow and other different colors. Because of the beautiful shape of camellia plants, leaves green and luster, colorful flower shape, very popular with people's favorite. Today, let's take a look at the cultivation methods and precautions of camellia with Xiaobian's legacy. The soil of camellia cultivation method camellia likes loose fertile, well-drained sandy soil, loess and humus soil growth. In general, when selecting soil culture, peat, rotten sawn wood, red soil, humus soil, or a mixture of above can be used for cultivation. The PH value for planting camellia is preferably between 5 and 6.5. The soil should be slightly acidic. Camellia cultivation method of light, temperature Camellia is a semi-shade plant, in the summer culture, need to give it shade. And after the beginning of autumn, the temperature drops, camellia enters the flower bud to spend money, this time to give it sufficient light in time. In winter, it should be kept indoors and placed in a sunny place. Camellia is a long-day plant, so it can form flower buds in a 12-hour environment. Its growth temperature should be 18-25℃, if it is higher than 35℃, its leaves will be burned. In winter breeding, its temperature should be kept 3-5℃ earlier, and it can also tolerate low temperatures of-10℃ for a short time, but it cannot exceed 16℃ for a long time, otherwise it will promote germination and cause defoliation. Camellia cultivation methods of watering, fertilization camellia on water requirements are relatively high, if in neutral or alkaline soil for its growth is ignored. When watering, adding too much water will cause the roots to rot. Basin soil can not be dry, it is easy to make roots shrink due to water loss, in order to keep the basin soil and the surrounding environment moist. During the flowering period of camellias, do not spray water. When watering, do not pour water on it, so easy to cause mildew of flowers, and shorten flowering. When the camellia flower Xie after please timely removal of residual flowers, winter watering is generally three days of watering, keep the pot soil moist can be. Camellia love fertilizer, usually in the pot when the foot will be applied base fertilizer. In autumn and winter, apply decomposed light liquid fertilizer once a week, and apply phosphorus and potassium fertilizer once or twice a week. When applying fertilizer, it can be watered with thin alum fertilizer water. After sprouting in spring, thin fertilizer water is applied once every half month, phosphorus and potassium fertilizer are applied in summer, fertilizer can be stopped for about one month in early autumn, alum fertilizer water is applied again before flowering, and available phosphorus and potassium fertilizer are applied again when flowering, so that flowers are big and colorful, and flowering is long. The pruning of camellia cultivation method When pruning camellia, mainly cut off dry branches, weak branches, cross branches and dense branches. If the buds of camellias interfere with the branches of the tree, pluck the extra buds. If it is potted camellia, you can trim it according to your own preferences, but when pruning, you can't cut it too heavily, which will impress its growth. 1. When watering camellias, be sure to store tap water in a bucket for a day or two to volatilize chlorine. It is best to put one percent of ferrous sulfate in water to improve water quality. 2, camellia should not receive too strong direct light, especially in summer and early autumn, must shade it. 3. When fertilizing camellia, if there is too much nitrogen fertilizer, it is easy to make the buds scorched, and less or no fertilizer can be applied after flowering. Because camellia is not cold-resistant, sometimes its flowering period will be delayed, this is relatively normal. Summary: camellia is an evergreen plant, its beautiful plant shape, leaves are dark green and luster, colorful flowers are traditional ornamental flowers in china,"ten famous flowers" ranked eighth, but also one of the world's precious flowers. The above is the introduction of camellia cultivation methods and precautions brought to you by Xiaobian. After reading the introduction of Xiaobian, I believe everyone knows better. Cultivation and maintenance method of camellia

Camellia has always been a very beautiful flower, camellia after flowering is extremely gorgeous, but also rich in flowers, people fall in love at first sight. camellias are so beautiful that many people want to plant camellias for viewing. So how to plant camellias is better, camellias cultivation and maintenance methods is what?

Cultivation and maintenance method of camellia

I. Cultivation and maintenance methods of camellia_planting places

Camellia is like a semi-shady planting environment, it is recommended to expose to the sun. Therefore, potted camellias are suitable for warm environments and well-ventilated places. Camellia cultivation needs a certain amount of light, but at noon and other sunny moments or pay attention to shade treatment, can not produce direct sunlight such problems.

II. Cultivation and maintenance methods of camellia-temperature

Camellia is more suitable for warm growth environment, that is to say, Camellia is most suitable for growth at temperatures above 15 degrees and below 25 degrees. Camellias stop growing above 36 degrees. At the same time, camellia cultivation should pay attention to temperature difference, temperature difference is larger, camellia will grow better instead.

III. Cultivation and maintenance methods of camellia-watering

Camellia watering should pay attention to dry and wet appropriate, spring camellia more conducive to germination, so you can water more. In summer, it is better to water in the morning or evening. Spraying water on the leaves is conducive to plant growth. In winter, it is better to water less and more pots of water.
