Can camellias be propagated by cuttings? how can camellias be grafted (when)

Camellia must be no stranger to many people, and we can see it in the market in our life. The ornamental value of camellia is very high, its petals are more, the color is common in pink, red, white and so on, which is very popular with consumers, so it attracts a lot of people's breeding. However, most people do not know much about the grafting and cutting methods of camellias.

Can camellias be propagated by cutting?

Camellia can be propagated by cuttings. The main methods are as follows:

The main results are as follows: 1. The most suitable cutting propagation of camellia is about the middle of June and the end of August. The semi-mature branches of the same year with full external tissue, complete leaves and full leaf buds were selected as cuttings, which were 8 cm long and 10 cm long, with 2 leaves at the apex.

2. When cutting, the base takes a little old branch as much as possible, and it is easy to form callus and root quickly after insertion. Cuttings cut early in the morning, to cut along with the cutting, insert the substrate of about 3 cm, cuttings require leaves to hand over each other, after cutting with fingers.

3. It is better to insert it shallowly, so that it can heal and take root quickly. The inserting bed should be shaded, spray the leaf surface every day, keep it moist, keep the temperature at 20: 25 ℃, heal about 3 weeks after insertion, and take root after 6 weeks.

4. When the root length is 3-4 cm, it is transplanted into the pot. When cutting, 0.4% 0.5% indolebutyric acid solution was dipped in the base of the cuttings for 2-5 seconds, which could obviously promote rooting.

How to graft camellias (when)

The main results are as follows: 1. In order to improve the survival rate of grafting, the rootstock must be grafted in the period of vigorous absorption of water and nutrients, usually from May to September. According to the experiment, the best grafting time is from June to July. At this time, the temperature is suitable, the scion of camellia has been lignified, the transplanted rootstock has survived, and the survival rate of grafting can be as high as 90%.

2. The method of tender branch grafting: the branch of semi-lignified scion is grafted on the new branch of non-semi-lignified rootstock, which is generally carried out by split grafting. After grafting, cover the scion and the grafting site with two layers of plastic bags, and cover the Kraft paper bag to cover the strong light. Gradually remove paper and plastic bags after survival. Because the rootstock and scion are young branches, the formation layer is thick, the healing is fast, and the survival rate is high, this kind of grafting method is the main method of camellia grafting or cultivating multiple varieties of camellia.

Management of Camellia after grafting

1. Loosening: when the axillary buds of the scion grow out, the sealed film can be untied. The tight bandage will be cut off in about 20 days to make it grow and develop normally.

2. in addition to sprouting: there are many sprouting branches and grow fast on the high-rootstock grafted rootstock, which must be removed in time, otherwise it will affect the growth of the scion, the light will cause the plant to grow slowly, and the heavy will cause the plant to wilt and dry. Sprouting should be removed until scion growth is dominant.

3. Shaping: after the grafting survived, the camellias should be properly reshaped. According to the needs of the camellia tree shape and branch position, the camellias should be bound and oriented with ropes.

How to control insect pests of camellias

1. Scale insects. Prevention and treatment: manual capture is the main method. If the disease area is large and the number of worms is large, it can be used. The scale insects can be killed by spraying 25% imidophos with 600 times aqueous solution every 1-2 weeks for 4 times in a row.

2. Tea yellow poison E. Prevention and treatment: the egg mass should be carefully searched and removed during the overwintering period. When the larvae gather together, the insect leaves can be taken off and trampled out. In the larval stage, spraying with 1000 times of 90% trichlorfon, 1000 times of 50% fenitrothion EC, or 3000 times of 50% phoxim EC had good results.

3. Tea coir moth. Prevention and treatment: in the cold winter season, the damaged leaves or branches should be pruned and cut off. If the injured area is not large, the larvae can be killed artificially. During the larval damage period, 1000 times of trichlorfon or 1000 times of dichlorvos milk can be sprayed and the effect is very good.

Camellias can not only be cut, but also grow well after cutting. in addition, camellias can also be propagated by grafting, which must be carried out at an appropriate time. Cutting and grafting only the maintenance is also very important, pest control must be done in place.
