Breeding method of Camellia sinensis

Camellia propagation can be selected by sowing propagation, cutting, leaning grafting, leaf cutting, high cutting, tree grafting and so on. According to the variety of camellias and the local ambient temperature, you can choose the right way of breeding.

Propagation methods of Camellia

1. Cutting

Select the well-growing, semi-lignified branches, remove the basal leaves, retain the upper 3 leaves, cut them into an oblique orifice with a sharp knife, immediately soak the incision in 200-500ppm indolebutyric acid for 5-15 minutes, then insert it into a sand basin or vermiculite basin after drying, water the wound for about 40 days, and take root for about 60 days.

2. Docking

The connecting time is usually between Ching Ming Festival and the Mid-Autumn Festival. First plant the rootstock in the flowerpot, cut off about half of the joint with a knife, the incision should be smooth, then make the cut of both sides closely fit, wrap it with plastic film, drench the rootstock twice a day, and heal after 60 days.

3. Leaf cutting

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.

4. High insertion

This method has the advantages of high survival rate, quick rejuvenation and early flowering. The method is as follows: the thin branches that need to be trimmed are girdled in an appropriate position, the girdling length can be between 5-8 mm, the plastic film of appropriate size is tied, and the disinfected peat soil or rotten leaf soil is added into the film, and after 7-10 days, the lower part of the plastic film is peeled again for 5-8 mm, which is called double-ring peeling and high insertion method.

5. Tree grafting

Grafting propagation of camellias has many advantages: it can maintain the excellent characters of varieties; it can accelerate plant growth, make it take shape quickly, and can be produced on a large scale; saving panicles, especially for those rare varieties with few sources of panicles, is particularly important; Camellia grafting technology: the grafting time is between June and July, when the new shoot leaves of camellia scion have been unfolded, and the temperature is high, the grafting wound heals quickly and the survival rate is high.
