The method of ramet propagation of Cymbidium

It is easy to produce tillers around the root neck of adult orchids, commonly known as "foot buds". People can use this kind of tillers to propagate. The ramet time is suitable for the combination of basin change in early spring from March to April, and it is best to wait until the foot bud grows to 15-20 cm high, because the tiller seedling itself has formed a good root system, grows rapidly after the ramet, and can blossom in about 2 years.

If the tiller seedling is less than 10 cm high, it will grow slowly after planting because the root system is not well developed, and it will take 3-4 years to blossom. When ramet, according to the location of the foot bud growth to determine the bud extraction mode (whether to pour the pot). The method is to remove the basin soil, and if the position of the offspring on the parent plant can be revealed, it is not necessary to pour the pot to take buds. There are two ways to take buds: break and cut. Do not cut buds where they grow in a suitable position for hand-breaking.

The practice shows that the survival rate of buds taken by hand is higher than that by knife, the mother plant is easy to heal, and the daughter plant takes root faster. The method: holding the false bulb of the mother plant with one hand and gently breaking the base of the daughter plant with the other hand, the daughter plant can be broken off. When cutting the bud with the knife, the offspring can be cut off at the joint between the daughter plant and the mother plant. No matter which ramet method is used, the wounds of mother and offspring should be coated with charcoal powder or fine furnace ash to avoid wound bleeding and decay. After the wound is dry, the base of the seed plant is buried with fine sand, and the root is promoted at a temperature of 20 to 25 ℃. Generally, after 20 to 30 days, callus can be formed at the wound, and new roots will be formed soon, and then transferred to the basin for cultivation.

The offspring propagated by ramets can generally preserve the variety characteristics of the mother plant, which is a feasible technical measure for the rejuvenation of aged plants. But there is also the phenomenon of budding. When the bud mutation is found, it is necessary to stabilize its variation and pass it on to the next generation, which is of great value in the breeding of Cymbidium.

How to separate plants of Cymbidium the method of operation in ramet culture

Magnolia, also known as Damulan, is a kind of flower that blossoms in winter and spring, avoiding high temperature. Cymbidium can be propagated by sowing or ramet method. The sowing seedlings of Cymbidium can grow 16 leaves and begin to blossom and bear fruit in the fourth year, and ramet reproduction can be carried out in the fifth year. Today, Xiaobian will introduce you to the operation of ramet.

When the seedlings germinate, the young leaves come together and drill out of the soil in the shape of a sword. at this time, the root seedlings do not grow their own roots, and the young leaves begin to take root only after the young leaves unfold, so do not rush to split up and let it grow on the mother plant for a period of time.

Before dividing the plant, remove the mother plant from the flowerpot, remove the surrounding soil, let the root system exposed, find out the part where the root seedling is connected with the mother plant, and cut them with a knife so as not to hurt the young roots on the root seedling.

Then the mother plant was planted with the new culture soil, and the root seedlings were planted in a small pot.

After entering the flowering stage, the bud of its rhizome germinates and gradually grows into a new bud, which is separated from the mother plant and transplanted in a flowerpot to grow into a new plant. The ramet ability of Cymbidium varies with different varieties. In practice, it is found that there are more buds in Cymbidium, but less in Cymbidium. Most varieties began to split after four years, and some of them began to sprout after two years of school break. The ramet slope with vigorous plant growth is less, and the ramet with weak growth potential is more. After entering the flowering stage, it can be divided every year, and the number of plants is generally 10 plants, and some varieties can reach more than 20 plants. But such a mother plant is easy to lose its ornamental value. 1. Ramet time: generally, there are more ramets in spring and autumn, mostly before flowering after seed collection, and it is better to take buds with roots when ramet, so that ramets have little effect on flowering and fruiting dumplings, and are easy to survive. It is possible to split plants without roots, and rooting treatment is needed to ensure the survival rate. 2. Ramet method: it can be cut by hand or knife. When ramets, hold the stem of the daughter plant by hand, gently remove it from the mother plant, or cut off the plant from the mother plant with a knife. From the perspective of practice, the survival rate of dissolving buds is higher than that of sprouting. 3. Management after ramet: after the plant is removed, the wound should be coated with charcoal powder or fine furnace ash, which can prevent water evaporation, cause wilting, disinfect the wound and prevent infection and decay. After the wound is dry, the rooted plant can be planted directly into the flowerpot. If the seed plant does not have a root, the root treatment should be carried out first. the specific method is to insert the plant into the washed fine sand, pour water thoroughly, put it at a temperature of 20 ℃ and 25 cm, so that it can often keep moist, and the new root can grow after 30 mi for 50 days.
