Because of chic elegance, the breeding method of cloves

The genus Syringa, also known as Syringa, is a deciduous shrub or small tree; most of it is for ornamental use, and some kinds of flowers can be extracted from aromatic oils, which are also nectar plants, so do you know how lilac flowers reproduce? Next, the editor will introduce to you the breeding methods of lilacs.

Breeding methods of cloves:

1. Branch propagation of cloves.

The propagation of cloves is usually carried out before sprouting in early spring or after defoliation in autumn. The sprouting seedlings in the rhizosphere of the plant were dug up with roots, planted separately, or the whole plant was dug out and planted in clusters. The ramets should be pseudo-planted in autumn and transplanted in the next spring. Prune the branches on the ground properly before planting.

2. Cutting propagation of lilac cuttings

The method of cuttage propagation of cloves is to take 1-2-year-old strong branches as cuttings and insert them directly into the hotbed to make them take root and sprout and form new plants. Usually, the top branch is cut off one month after the spring flower fade for cutting. the length of the cuttings is 10 to 15 meters, with 2 to 3 pairs of bud nodes, one of which is buried in the soil. Under the condition of 25 ℃, it takes root in 30 to 40 days. When the young root changes from white to yellowish brown, the seedlings begin to transplant.

3. Lilac striping propagation

Cloves can be propagated by strip pressing, which is generally best carried out in February, when the rhizosphere sprouting shoots are pressed into the soil, and if the branches are too thick, they can be cut and then pressed. Keep the soil moist after pressing, it can take root in 2-3 months, and the mother plant can be isolated in autumn of that year and planted separately.

4. Budding propagation of clove

Clove bud grafting is a very common propagation method. The full leaf buds on the sturdy branches of the same year should be selected for scions, and 1-2-year-old clove seedlings should be selected for rootstocks. When grafting, the leaves on the scion should be cut off, leaving only the petiole, and then cut across 1 cm above the bud, and then cut upward from 1 m to 1.5 m below the bud to peel off the xylem in the cortex. Cross-cut the rootstock from 5 to 10 meters from the ground, then cut a vertical knife about 3 meters long from the middle of the cut to make it in a "T" shape, then gently peel off the skin and insert the scion into the mouth of the "T" word. The scion and the rootstock should be closely matched, and finally tied with plastic film strips. 2 to 3 weeks after budding, if the petiole on the scion falls off naturally, the bud has survived, and the plastic strip can be released at this time.

5. Clove branch grafting propagation

Clove branch grafting is generally carried out before germination in early spring, the scion length is 8 to 10 meters, with 2 pairs of bud nodes, the lower sides of the scion are cut into a bevel. The 2012 clove seedlings are selected for the rootstock, cut off the top at 5 to 10 meters above the ground, split a gap vertically down from the cross section of the rootstock, and then insert the scion. The slope of the scion should closely match the rootstock and be tied up with plastic strips. In order to prevent the grafting knife edge from losing too much water, you can bury it with moist soil and remove the covered soil after the buds on the scion sprout.

6. Lilac propagation by grafting

The propagation of cloves by grafting is to cut the scion of cloves and the rootstock with an interface of the same size and bind them closely together. When the knife edge produces callus, the rootstock is cut off from the top branch 1 meter above the interface, and the scion is cut 1 meter below the interface, so that it becomes a new plant.

7. Sowing and propagation of cloves

Cloves can be sown and propagated, and a large number of seedlings can be obtained at the same time, but this way of propagation is easy to change. It is generally carried out in spring, soaking seeds in clean water for 1-2 days before sowing, or soaking seeds in 40-50 ℃ warm water for 2 hours. After being removed, mixed sand (1 seed and 2 parts of sand) is used to accelerate germination and keep moist. After about 1 week (early April), it can be sowed on the seedling bed. After sowing, the seedlings can be unearthed after sowing with lcm, which is often kept moist. After being unearthed, there should be time seedlings, ploughing, weeding, watering and fertilization, and they can be planted in the next spring.

There are many breeding methods of cloves, we can choose according to their own actual situation, and some varieties of cloves are excellent, and we can also choose tissue culture to propagate. If you want to know more about plant farming, please continue to follow the No.1 Home Network.
