The cultivation points of the camellia capital, how to cultivate the camellia tree

Camellia seedlings are suitable for growing in loose and breathable, well-drained soil, and the soil needs to be slightly acidic, so that camellia seedlings can grow more vigorously, and ground-planted seedlings need to be loosened and fertilized in advance. Bonsai.

For planting, it is necessary to mix humus, sandy soil and basal fertilizer to form nutrient soil.

Carry out planting. During the growth of camellia trees, it is necessary to give sufficient light, camellia trees are more resistant to shade and light, but the light in the growth environment should not be too strong, and in the summer when the temperature is high, shading measures can be taken to avoid burning the leaves at high temperature.

In addition, during the growth period of the camellia tree, sufficient nutrients need to be given to maintain the normal growth of the camellia tree, and the camellia tree can be fertilized every other month to allow the camellia tree to absorb nutrients and grow more vigorously.

Key points of maintenance: 1. Watering is an important part of cultivating potted camellia, and the principle of camellia watering is that the flowering and growth period can be slightly wet, and the dormant period can be slightly dry; In summer and autumn, the temperature is hot, the rainfall is low, and the air is dry, so the potting soil should be kept moist and not dry, and the plants should be sprayed with leaf water to increase the air humidity.

and reduce the temperature, which is conducive to the growth of camellia. On rainy days, you should water less or no watering, and on rainy days, you should also prevent potting soil from watering.

2. Pay attention to reasonable fertilization. Camellia.

After thanksgiving, in May and June, apply the dilute solution of fully decomposed soybean cake twice a month, and apply the mixed fertilizer solution mainly phosphate fertilizer 3 times a month from July to before the flowering. Fertilization should be done in the evening on a sunny day. Before fertilization, stop watering, so that the potting soil is slightly dry and absorbed, and the next morning after the "return water".

2 Do not fertilize in April.

3. Pay attention to bud thinning. In August, the buds grow on the inner branches, overlapping branches, and crossed branches.

Pluck it off, or cut it off along with the branches. At the top of 1 branch, only 1 strong flower bud is left, and the rest is removed.

There are four cultivation techniques for camellia trees, namely cuttings planting, grafting planting, strip planting and sowing planting.

1. Cuttings planting.

It is best to plant cuttings from mid-June to late August. Cuttings need to be of the same year with intact foliage on the outside of the canopy of the camellia tree, and their length is between 8 and 10 cm. Immediately after cutting the cuttings in the early morning, insert them into the land to a depth of about 3 cm.

Cuttings need to be in the shade and need to be watered on the leaf surface. The temperature is best between 20 and 25 degrees Celsius, and the roots will take place in about 6 weeks after cuttings. When the roots have grown to 3-4 cm, they can be transplanted.

2. Grafting and planting.

If the variety of the camellia tree is not suitable for cuttings planting, and it is difficult for cuttings to take root, grafting can be used. Note that it is necessary to graft with new shoots that grow to May to June and a half.

3. Strip planting.

Use healthy 1-year-old camellia twigs for the strips. Peel off the bark at the top 20 cm and cover the branches with humus, wrap them with plastic film, and take root after about 2 months.

Fourth, sowing and planting.

This method is suitable for use on single-petaled camellia seeds. Shallow planting in October is OK.

Camellia japonica, scientific name: camellia japonica

Aliases Camellia, Camellia, Mandala Tree, Late Camellia, Winter, Sandalwood, Foreign Tea, Mushroom Spring, Tsubaki.

There are about 220 species of Camellia sinensis and Camellia sinensis, among which Camellia sinensis, Camellia sinensis, Camellia sinensis, Camellia chinensis and Camellia chinensis found in China in recent years are all important ornamental flowers and trees.

Camellia can tolerate a maximum humidity of 35, above which sunburn occurs. When the temperature rises above 10, germination starts, and growth stops when the temperature rises above 30, and the optimal temperature for growth is between 18-25. The temperature of the first flowering of the camellia is 2, and the temperature suitable for the opening of the flowers is between 10-20.

Camellia likes high air humidity, avoid dryness, requires good soil drainage, and pay attention to drainage in the rainy season and typhoon season in the south of the Yangtze River, so as not to cause root rot and death d in areas with annual rainfall of more than 1200 mm, can grow well. Camellia sinensis prefers fertile, thiophapine, slightly acidic loam or humus soil, and the pH value can grow in the range of 4 5-6 5, with 5 5-6 5 is preferred, and the alkaline soil is not suitable for the growth of camellia. Camellia sinensis has 2 branches in 1 year, the first time begins to germinate from mid-March to mid-April and late April, and stops growing in mid-to-late May, commonly known as spring shoots; The second germination occurs in mid to late July.

In September, it is called Xia Shao; After that, it enters the cessation phase of growth. The growth of spring shoots is large, and the growth of summer shoots is small. Under normal conditions, the flowering period of a single flower is about 7 to 15 days, and the life span of a single flower can be about 1 month longer if the flowers of the same double-petaled variety open in late autumn and early winter.

Yunnan camellia is shade-tolerant and likes a half-group and half-yang environment. The most suitable temperature is 18-24, and the temperature response is more sensitive, and at 5-6 hours, it may be frost damaged. Likes high humidity and breezes.

It should be planted in acidic soil with a lot of humus and loose. Camellia sinensis is a tropical plant that prefers warm and humid environments. It is waterlogging tolerant, suitable for growing in secondary evergreen broad-leaved forests in valleys and ditches, and is negative.

The suitable temperature for growth is 23-30, and the short-term winter 2-4 can also be tolerated, but the low temperature period can not be too long.

The camellia tree is 3-6 meters tall, with a diameter at breast height of up to 24-30 cm, and its bark is smooth and grayish-brown. Naturally bred in the rolling mountains all year round, the adult trees are about 3 meters tall and more than 100 years old, some can reach 400 500 years. It is a unique oil tree species in China, which is only distributed in some alpine areas of a few provinces and counties in southern China.

Experts call it "God-given China" and the king of oil". Camellia oleifera has single leaves and alternate leaves, the flowers are white of both sexes, and the fruit can not mature until October of the following year after flowering in October, so there will be a rare phenomenon of flowers and fruits of the same plant.

Camellia oleifera single-leaf alternate, the flowers are both white, the flower buds begin to form in April and May every year, bloom in October and November, and the fruit can only mature after flowering in October of the following year, at the same time, the tea fruit of the previous year is also nearly ripe, therefore, the Camellia oleifera tree will have a rare flower and fruit homogeneous phenomenon. Therefore, the folk have the reputation of "holding a child and conceiving a child" for the camellia tree. Camellia fruit has a long ripening cycle, from flowering to fruit ripening, it has been nourished by clouds and mist in spring, summer, autumn and winter for nearly seven seasons, absorbing the natural essence, which is indeed a treasure in the world.

Bloom early, the flowering period is long, the flowers are big, many, and bright, and the ancients called it "the four friends in the snow" with red plum, spring, and narcissus. Camellia sinensis is not like a pile, where the whole flower falls, but the petals slowly wither one by one until the end of life.

Camellia fruit is a capsule, mostly oval in shape and with fine hairs. The seeds are mostly yellowish-brown, shiny, triangular. Commonly known as camellia seeds, it is spherical and peach-shaped, and can be refined from important natural green organic health edible oil--- camellia oil.

This is an all-natural green health food. Long-term consumption of camellia oil has obvious curative effects on cardiovascular diseases, lowering cholesterol in serum, hypertension, cardiovascular and cerebrovascular, obesity, etc., especially for postpartum recovery of mothers. The digestion and absorption rate of camellia oil reaches 97%, far exceeding that of ordinary cooking oil, and it is undoubtedly one of the best health edible oils in the world today.

The growth of camellia mainly depends on the fertilizer energy provided by the soil and daily watering, and the most important point is to have enough sunlight, because only sufficient sunlight can make its leaves fully photosynthesize, so it is more beneficial to its growth.

Camellia sinensis grows mainly by soil and sunlight.

Speaking of the cultivation of camellias, it dates back to the Three Kingdoms period.

Three Kingdoms: Camellia cultivation in China dates back to the Shu Han dynasty (221-263 AD).

At that time, people attached great importance to the status of camellia, and camellia was listed as "seven products and three lives".

According to the data, there are more than 20,000 registered camellia varieties in the world.

There are 883 varieties of camellia in China.

In the Three Kingdoms period, camellia was already cultivated artificially.

However, until the Northern and Southern Dynasties and the Sui Dynasty, the imperial court and the aristocratic courtyard were still wild and primitive camellias, and the flowers were single-petaled and red.

At that time, the literature about camellia and the poems of "camellia" and "sea pomegranate" chanted by literati did not involve the name of the variety.

The first Chinese record of camellia varieties was in the Tang Dynasty Prime Minister Li Deyu (787-850) in the Pingquan Mountain Dwelling Grass and Trees.

It is the age and the mountain - Zhentong Mountain Tea.

"Zhentong Mountain Tea" is a single braid flower, and now it is the original red mountain tea "Golden Heart Red" about 1,200 years ago.

In the Southern Song Dynasty's "Huiji Continuation", it is the "Zhentong Mountain Tea" volume 4 "Camellia" article mentions Zhentong Mountain Tea, saying: "In the Tang Dynasty, only Huiji has it.

Its species are now everywhere.

And he said, "Its flowers are bright red and lovely, and they are durable."

Huiji, that is, the ancient name of Shaoxing, Zhejiang.

Ji Mountain, is a mountain range in the territory of Huiji.

This means that the color of the flower is bright red and that the flower is durable.

The Song Dynasty recorded 15 varieties of camellias.

Yue Dan, Yu Ming, Du Sheng, Heding Red, Yellow Fragrance, Pink, Jade Ring, Red and White Leaves, Yuedan, Tusi, Jade Chime, Peach Leaves, Mouth Tea, Jade Tea, Thousand Leaves Tea.

1. Soil. Potting soil is important for the growth and importance of camellia, so it is necessary to be cautious when choosing soil, usually with high humus content and slightly acidic soil, so as to meet its needs for soil.

2. Temperature. Camellia is afraid of high temperatures and low temperatures, so the temperature is best between 18 and 25 degrees, if the temperature is too high or too low, it will affect its growth, especially in winter, it is necessary to move it back to the room for maintenance, and when there is sun at noon, it can be moved to the balcony. In the summer, it is necessary to protect from exposure to the sun, and the temperature is too high.

3. Watering. Camellia loves moist places, so moisture is important to it, but make sure to water it in moderation, not too dry or too wet, otherwise it will affect root growth. If it is in summer, you can water more water to facilitate its growth, if it is winter, you need to reduce the amount of watering, once every 2 to 3 days to prevent frost damage.

4. Fertilization. Camellia likes fertilizer, so in the maintenance, the amount of fertilizer should be sufficient, especially in the growth period, in addition to adding fertilizer that is conducive to growth, it is also necessary to add potassium dihydrogen phosphate, which can promote its later flowers to be more colorful, but remember not to fertilize too much, otherwise it will affect the growth of roots.

5. Periodically. Pruning is also very important in maintenance, when it has too many buds, it needs to be pruned regularly, cut off the weak branches on the top, and tidy up the buds, so that it can better absorb nutrients.

Camellia seedlings are suitable for growing in loose, breathable, well-drained slightly acidic soil. When planting camellia trees, it is recommended to choose high-altitude mountainous areas, where water is more abundant, and the humidity is larger, and the astigmatism is stronger, which is suitable for the growth of camellia trees. In addition, during the growth period of the camellia tree, it is necessary to give a certain amount of upper light irradiation to make the camellia tree grow more vigorously.

Camellia tree growth process has a certain demand for water, it is suitable for growing in a humid environment, planting camellia trees can choose a certain height of the mountainous area, such terrain rainfall is more abundant, and the humidity is larger, astigmatism is stronger, suitable for the growth of camellia trees.

During the growth of camellia trees, it is necessary to give sufficient light, camellia trees are more shade-tolerant and light-loving, but the light in the growth ring cavity should not be too strong, and in the summer high temperature, shading measures can be done to avoid high temperature burning leaves.

In addition, during the growth period of the camellia tree, sufficient nutrients need to be given to maintain the normal growth of the camellia tree, and the camellia tree can be fertilized every other month to allow the camellia tree to absorb nutrients and grow more vigorously.
