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.
