How to cultivate the offspring of Cymbidium

For the magnolia which uses ramet propagation, the growth ability of the offspring that has just left the mother is relatively weak, so careful care is needed to make the offspring survive. The editor will introduce to you how to maintain the sub-plant after the ramets.

1. The root system of the good seed plant should be retained as far as possible when ramet. The more roots, the more conducive to the normal growth of offspring.

2. Smear the wound with clean fine furnace ash, charcoal powder and plant ash in time to make it dry quickly and prevent water evaporation and bacterial infection.

3. For rootless progeny, don't rush to put it into nutritious soil for maintenance. After the wound is slightly dried, it is first buried in sterilized fine sand, sawdust or perlite for root treatment. Keep the soil moist at a temperature of 20 ℃ to 25 ℃. New roots can be grown after about 50 days, and then planted in nutritious soil for normal maintenance.

4. Watering should be controlled. The offspring that have just left the mother plant and planted in the nutritious soil should not be watered too much for the first time to prevent the wound from being infected and rotten.

How to plant propagation of Cymbidium in the propagation method of Cymbidium is more commonly used, there are flower friends do not know how to plant, for fear of improper treatment, in fact, the ramet is not as complex as you think, master the time is half successful, the best time is the average temperature between 15 ℃ ~ 25 ℃, the south of the Yangtze River can be carried out before and after Ching Ming Festival. At this time, Cymbidium has just blossomed and entered a vigorous vegetative growth period. while turning over the pot and changing the soil, young plants can be cut and propagated. In the second half of the year, the ramet can be carried out between White Dew and the Autumn Equinox, so that the new plant after being cut off from the mother has a longer growth period. Whether it is a ramet in spring or autumn can be determined according to the size of the seed. After the daughter plant is too small, the growth is slow, and the daughter plant is too large, which affects the growth of the mother plant. In general, when the daughter plant grows 3 to 5 leaves, it is very beneficial to the growth of the daughter plant and the mother plant. In other words, what should be reversed in the first half of the year cannot be put off until the second half of the year, still less can it be put off until the next year. The specific method of gentleman orchid ramet 1, blade: can choose medical scalpel, or decoration with thin slice knife, it is best to use potassium permanganate solution disinfection and sterilization before use. 2. Prepare flowerpots and potted soil. The flowerpot should be well drained, loose and breathable and free of germs. The basin soil can be prepared for two kinds of substrates. One is pure sand matrix. Sift out the powder in the ordinary river sand with a fine sieve, then rinse it with clean water, then rinse the poison with boiling water, and set aside after drying. River sand is an excellent substrate for rooting of ramets of Cymbidium, which is very beneficial to the planting and survival of seedlings. Second, rotten leaf soil, this acidic soil contains a variety of nutrients, which is suitable for cultivating seedlings with roots cut off from the mother. Using this medium to cultivate split seedlings, generally slow seedlings a few days later, the seedlings can restore vitality, and quickly use their own roots to absorb water and nutrients from the substrate for healthy growth. 3. After cutting, the prepared vitamin B12 solution should be used to smear the wounds of the mother and daughter plants, and the wounds should be dried and disinfected with charcoal powder or sulfur powder. After this work is done, seedling cultivation can be carried out. 4. In ramet operation, the mode of bud selection should be determined according to the growth position of the daughter plant. Whether it is necessary to turn the basin depends on the exposure of the daughter plant, if the exposure condition of the daughter plant is good, and the mother plant is less than two years after turning the basin, it is not necessary to turn the basin to remove buds. As long as the culture soil is planed, the position of the offspring on the mother can be seen, and the buds can be cut and propagated; if the offspring grow at the bottom of the rhizosphere of the mother, the basin must be turned. The whole plant can be gently lifted, the attached old soil can be shaken off, the daughter plant can be exposed, and the sub-plant can be taken by the method of breaking or cutting. During the operation, the faster the knife, the better, and the smaller the wound, the better, which is beneficial to the wound healing and growth of the seedlings. 5. The depth of pot cultivation should be based on burying the rhizome of the seed plant and stabilizing the plant. When potting, we should pay attention to the close attachment of the seedling rhizome and sand grains. Straighten up the seedlings that are tilted by watering. For rootless ramet seedlings, if they are unstable during cultivation, bamboo sticks can be inserted into the substrate, and then the ramet seedlings can be tied to the bamboo sticks to make them fixed. Generally, after 30 to 40 days, new roots can grow smoothly. The main point of the ramet of Cymbidium is to cut off the axillary buds from the pseudobulb and root joint from the mother and carry out in vitro culture, which is called the ramet propagation of Cymbidium. The adaptability and regeneration ability of Cymbidium are very strong. A pot of adult Cymbidium can often send out several or even a dozen axillary buds a year. These buds, whether they take root or not, can be cut from the mother and cultured in vitro to develop into new plants.

The ramet propagation of Cymbidium has the advantages of simple operation, high survival rate and rapid growth and development. In the process of ramet, we should pay attention to the following technical points.

First, the best time for ramet

The best time: the best time for the ramet of Cymbidium varies from place to place. If there is greenhouse equipment, it can be carried out all the year round. In the Yangtze River basin and its southern area, the ramet can be carried out before and after Ching Ming Festival in the first half of the year. At this time, the temperatures in the above areas are generally between 15 ℃ and 25 ℃, and the orchid has just blossomed and entered a vigorous vegetative growth period. The grower can make use of this opportunity to turn the basin and change the soil, and cut the axillary buds to propagate. Ramets must be carried out between White Dew and the Autumn Equinox in the second half of the year. The autumn ramet should be as early as possible, so that the new plant after being cut off from the mother has a longer growth period. Generally speaking, the fruit of Magnolia has basically matured from September to October. In order to blossom well next year, it is often necessary to turn the pot and change the soil in autumn, so that the plant can get enough nutrients in the second vigorous growth period. While turning the basin, it is advisable to take its axillary buds to propagate.

The best leaf age: is it better to ramet in spring or autumn? This depends on the size of the offspring. After the daughter plant is too small, the growth is slow, and the daughter plant is too large, which affects the growth of the mother plant. In general, when the daughter plant grows 3 to 5 leaves, it is very beneficial to the growth of the daughter plant and the mother plant. In other words, what should be reversed in the first half of the year cannot be put off until the second half of the year, still less can it be put off until the next year.

2. Preparation and implementation of ramets

Preparation: the preparation work must be done before the branch of Cymbidium. ① sharpens the knife. By rubbing with grindstone, the cutting knife can remove rust on the one hand and produce high temperature on the other hand, which can play the role of disinfection. After grinding the knife, wipe it with clean gauze for use. Prepare the basin for ②. Prepare flowerpots and pots of soil. The flowerpot should be well drained, loose and breathable and free of germs. The basin soil can be prepared for two kinds of substrates. One is pure sand matrix. Sift out the powder in the ordinary river sand with a fine sieve, then rinse it with clean water, then rinse the poison with boiling water, and set aside after drying. River sand is an excellent substrate for rooting of ramets of Cymbidium, which is very beneficial to the planting and survival of seedlings. Second, rotten leaf soil, this acidic soil contains a variety of nutrients, which is suitable for cultivating seedlings with roots cut off from the mother. Using this medium to cultivate split seedlings, generally slow seedlings a few days later, the seedlings can restore vitality, and quickly use their own roots to absorb water and nutrients from the substrate for healthy growth. ③ prepares medicine. Prepare vitamin B12 solution and charcoal powder. Vitamin B12 solution is used to smear the wounds of mother and offspring, and charcoal powder is used to dry and disinfect the wounds. After this work is done, seedling cultivation can be carried out.

Cultivation: when ramet operation, according to the growth location of axillary buds, to determine the way to take buds. Whether it is necessary to turn the basin depends on the exposure of axillary buds. If the exposure conditions of axillary buds are good and the mother plant is less than two years after turning the basin, it is not necessary to turn the basin to remove buds. If the culture soil is planed, the axillary buds can be cut and propagated as long as you can see the position of the axillary buds on the mother; if the axillary buds grow at the bottom of the rhizosphere of the mother plant, the basin must be turned over. You can gently lift out the whole plant, shake off the attached old soil, expose the axillary buds, and use the method of breaking or cutting to remove the seedlings. During the operation, the smaller the wound, the better, which is beneficial to the wound healing and growth of the seedlings. The depth of pot cultivation shall be based on burying the rhizome of the seed plant and stabilizing the plant. When potting, we should pay attention to the close attachment of the seedling rhizome and sand grains. Straighten up the seedlings that are tilted by watering. If the ramet seedling is rootless and unstable during cultivation, it can be inserted into the substrate with a bamboo stick, and then the ramet seedling is tied to the bamboo stick to make it fixed. Generally, after 30 to 40 days, new roots can grow smoothly.
