How do camellias propagate?

Camellia is often propagated by cutting, and can also be propagated by pressing and grafting.

The main results are as follows: (1) the method of cutting is the most suitable from April to July. Select annual, sturdy, pest-free twigs as cuttings, cuttings about 10 cm long, leaving 1 top bud, 1 lateral bud, 2-3 leaves, and all the lower leaves are removed. Soak the cuttings in the solution of naphthalene acetic acid or indolebutyric acid (concentration 200ppm~500ppm) for 8 hours for 12 hours, then rinse with clean water and insert them into a seedbed or basin equipped with fine sand or vermiculite to prevent direct sunlight. Water in time after insertion and spray 2 or 3 times in sunny days to keep the soil moist. In cloudy and rainy days, there is no need to shade the sun. After careful management, new roots will be sent out in 60-70 days.

(2) striping method: generally in April, the tender branches of the same year are selected, the part of the human soil is cut with a knife or peeled in a ring, and then the cut is pressed into the soil to keep the soil moist and cut off the mother plant after rooting.

(3) split grafting method: from February to March, the single-petal camellia or the seedlings of Camellia oleifera seeds were selected as rootstocks, and the new shoots of the excellent varieties of the same year were used as scions, the scion had 1 leaf and 2 leaves, and the base was cut to 1 cm to be wedge-shaped. Cut off the rootstock 3 cm to 5 cm from the root neck, then cut 2 cm deep and insert the scion into the incision of the rootstock to align the rootstock with the scion, tie it tightly with hemp and place it in a cool place. From June to July, grafting was carried out by relying on grafting.

How do camellias reproduce? Introduction to the propagation methods of camellia

Camellia is mainly distributed in China and Japan. It has been cultivated in the open fields of central and southern China for 1400 years. There are many methods of reproduction. Both sexual reproduction and asexual reproduction can be used, among which cutting and grafting are the most common. Let's take a look at these propagation methods of camellia.

Cutting Propagation of Camellia

This method is the most simple, and the cutting time is the most suitable in September, or in spring, choose to grow well, semi-lignified branches, remove the basal leaves, retain the upper three leaves, cut into an oblique mouth with a sharp knife, immediately soak the incision in 200-500ppm indolebutyric acid for 5-15 minutes, insert it into a sandbasin or vermiculite basin after drying, water the wound for about 40 days, and take root for about 60 days. The cuttings treated with hormone took root 2-3 months earlier than those without hormone. Vermiculite is used as a slotting bed, and it takes root much faster than a sand bed.

Propagation of Camellia by grafting

Choose appropriate varieties such as tea cup tea or Camellia oleifera as rootstocks, pick up the valuable camellias, usually between Ching Ming Festival and the Mid-Autumn Festival, first plant the rootstocks in the flowerpot, cut off about half of the joint with a knife, the incision should be smooth, and then make the cut of both sides closely fit, wrap it with plastic film, drench the rootstock twice a day, heal after 60 days, and then cut off and plant. And put it in the shade of the tree to avoid direct sunlight. In February of the following year, the tail of the rootstock was cut off with a knife and then planted.

Leaf cutting Propagation of Camellia

Camellia is generally propagated by branch cuttings, but some valuable varieties are limited by the source of branches, or considering that the tree shape will be affected after sampling, so the leaf cutting method is also used. Using mountain mud as the cutting substrate, it can be mixed with 1 stroke 3 river sand to facilitate ventilation and drainage, and the matrix is stored in a tile basin, and then cut in the basin. Leaf insertion is best carried out in the rainy season, take one-year-old leaves as leaf insertion material, too old is not easy to root, too young and easy to rot. Insert about 2 cm into the soil, press the soil after insertion, pour enough water, and then put it in a cool and ventilated place. Generally, it can take root in 3 months, and it can sprout and branch in the next spring.

High-cutting Propagation of Camellia

The most important feature of the high-altitude cutting method is that it can give new life to all the weak twigs that should have been trimmed off from the camellia. And this method has the advantages of high survival rate, quick rejuvenation and early flowering. The thin branches that need to be pruned are girdled in an appropriate position. (generally, the upper part can be left into 15-25 cm branches) the girdling length can be between 5-8 mm, the plastic film of appropriate size can be bound, and the sterilized peat soil or rotten leaf soil will be added to the film. After 7-10 days, the lower part of the plastic film will be girdled for 5-8 mm, which is called double-ring peeling high insertion method.

Tree grafting Propagation of Camellia

Camellia is a plant that is difficult to survive. There are many propagation methods of camellia, among which grafting is the most commonly used. Grafting has many advantages, which can maintain the good characters of varieties, accelerate plant growth and make it take shape rapidly. and large-scale production, saving panicle, especially for those rare varieties with few sources of panicle, is particularly important. Camellia grafting technology: the suitable grafting time is from June to July, when the new leaves of the scion of camellia have been unfolded, the temperature is high, the grafting wound heals quickly and the survival rate is high. The grafting method is the cutting method in the grafting method, which is often called "high grafting head" because of the high position of grafting.

There are many ways to reproduce camellias, including sexual reproduction and asexual reproduction. Asexual reproduction is usually used near Guangzhou, in which the circle branch method (air striping) and cutting method are the most. Various methods of reproduction are introduced as follows. 1. Sowing and propagation: after the fruit is ripe in December, the seeds are collected and sown, or the seeds are stored in sand, or they can be sown between February and March of next spring. It should be shaded after sowing and germinate after two months. Pay attention to strengthening management, timely weeding, loosening soil and fertilization. It was transplanted once in the autumn of that year or in February or March of the following year, and properly cultivated. It begins to blossom in the third or fourth year, and the plants can also be used as rootstocks for grafting. 2. Cutting propagation: the varieties suitable for cutting propagation are Guanfen tea, Dahong and so on. Generally, the twigs on the well-growing plants are selected in September, the leaves in the lower part of the growing point are removed, the upper 8 leaves are retained, and the skin layer is peeled off at the growing root. After the sarcoma grows, it is cut off before "Greater Cold" (late January). Wrap the sarcoma in mud and cut it into the sand. This kind of cuttage has higher survival rate and faster rooting. 3. Circle branch propagation: the varieties suitable for ring branch (air striping) breeding are tea, Fujian camellia, Wubao tea, big black tea, official powder tea and so on. The method of encircling branches is to select disease-free branches at the beginning of March, about 15-20 cm long, peel off the 1cm-long cortex, scrape off the cambium, then cover the circle with mud and drench it with water every day to keep it moist. After 100-120 days, they were cut off with scissors, planted in a seven-jin basin for every 10 plants, and managed in a shady place. They were transplanted in February and March the following year, and two plants were planted in one pot. In October, a single plant was planted in a five-kilogram or seven-kilogram basin.
