How to split an orchid with a burst pot? Propagation skills of Orchid ramet

Flower lovers who cultivate orchids all know that orchids are bound to become large pots after they have been raised for many years, and it is time to divide them. In fact, the key to dividing the basin lies in the ramet. So how to split orchids in potted plants? Let's take a look at the ramet propagation techniques of orchids.

I. conditions and timing for ramet propagation of orchids

1. The ramet condition of orchid: the ramet usually grows after two or three years and the orchid plant has grown in the whole basin; in order to improve the germination rate or rapidly increase the number of breeding varieties, the conjoined orchid clusters with more than 4 plants are divided; and in order to prevent the degeneration of buds becoming odd, only one old and one new conjoined mother cluster is divided.

two。 Orchid ramet time: orchid ramet propagation can be carried out in all seasons of the year, but in order to ensure the survival rate, it is often carried out at an air temperature of 12 ℃ to 30 ℃. According to its physiological characteristics, the best time is at the end of flowering. Because the vegetative growth of the orchid plant is tired at this time, not only the new bud has not germinated, but also the growth point of the bud has not yet expanded, and the ramet is not easy to cause accidental injury. At the same time, the flowering period is over, generally there will be no more flower buds, there is no problem of damage to flower buds due to ramets. In addition, through ramet, it can also promote the activity of vegetative growth and improve the resilience and germination rate of orchid plants.

2. Key points of split propagation techniques of orchids.

1. Rise the seedlings.

When ramets change pots, the soil should be drier. If the basin soil is too wet, it is inconvenient to operate, and it is easy to break and injure the fleshy root. After turning out the mother plant when changing the basin, gently remove the mud and shake off the matrix in the root mass. If the matrix is hardened or sticky, it should be washed away with water and then clustered.

two。 Wash and dry the roots.

It is best to wash the roots with tap water. Soaking in water is easy to infect diseases and insect pests. After washing off the matrix, spread the orchid plant in the sun, cut off the rotten roots and cut off the roots. Wash the roots and leaves with clean water, dry the orchid roots and soften them, cut them with scissors at the bulbs with large gaps, and coat them with charcoal powder or sulfur powder to prevent bacterial infection, and then wait for seed.

3. Pick the basin. The ventilation degree of orchid basin is directly related to the growth of orchids. Generally speaking, tile basin is the best, purple sand basin is the second, and porcelain basin is the worst. When using the new tile basin, you should pay attention to soak in clean water for 3 days, then soak in disinfectant water for 2 hours, and then dry. For orchids that are difficult to grow, it is more appropriate to use tile pots. If you need indoor decoration or exhibition, you can use porcelain pots or glaze basins in tile basins. The bottom of the orchids must be filled with thicker materials to ensure ventilation and ventilation.

4. Put the ramets on the pot.

When the orchid is on the pot, the filling layer generally accounts for 1 to 4 of the height of the orchid pot, and the length of the root group is preferably 1 to 3 of the height of the orchid pot, so the ideal orchid pot is generally higher than other flowerpots, and the combination of the pot waist can be large or small, in short, it is necessary to let the orchid root have enough space to grow.

Potted orchid plants are generally based on the conjoined bodies of the second or third generations, and several bundles of natural plants are planted appropriately depending on the size of the basin, and then the fine soil is 2cm away from the mouth of the basin. Lift the orchid plant slightly to make the root stretch naturally, and the extraction height should be equal to the upper end of the pseudobulb and the basin soil surface, not too deep or too shallow. Shake the basin again so that the soil is in close contact with the root. And compacted around the basin by hand, so as not to cause holes when watering.

5. Management after being put into the basin.

The top layer of the flowerpot is covered with a layer of lichen or broken tiles, so that watering is not easy to cause basin soil consolidation and reduce basin soil moisture evaporation. The first watering is best to use the sitting pot method, the orchid pot to be planted is put in the water, and the basin surface is 3cm above the water surface, so that the water slowly permeates from the bottom up, wait for the water to infiltrate to the soil surface of the basin, and take out the orchid pot from the water. You can't directly bask in the sun for about 15 to 30 days in the shade. Watering should be controlled during this period and should not be too wet. Later, move to half-yin and half-yang, ventilated and ventilated, where you can get to the sun in the morning. Whether it is balcony cultivation or courtyard cultivation, it is best to put the flowerpot on the four-sided ventilated orchid rack, and the closed balcony should have sliding windows, which is good for reducing orchid diseases and insect pests.

This is the end of the introduction to the split propagation of orchids. Ramet propagation is the most traditional propagation method, which has the advantages of simple operation, high survival rate, rapid plant growth, early flowering, ensuring quality characteristics and so on.

Reference for methods and steps of turning pots and ramets of orchids in autumn

Potted orchids on the balcony

During the holiday, I visited a friend's house and saw that the balcony was covered with orchids. I was very envious, so I asked my friend for advice on how to do it. The friend said that in addition to the usual careful care, we should also do a good job of turning pots and ramets in autumn. In this way, several pots of orchids can be added every year. I asked the specific method of operation and shared it with you here.

Turning pots and ramets of orchids in late autumn is one of the best periods, if handled well, not only can produce small orchids, but also will be very beneficial to the flowering and growth of orchids in the coming year. Therefore, orchid friends should attach great importance to the work of turning pots and ramets in autumn.

Points for attention in turning pots and ramets of orchids:

① should dry the soil slightly before turning the pot to prevent damage to the orchid root.

② ramets such as scissors or knives should be sterilized.

③ orchid ramet incisions and pruned root wounds should be coated with germicidal powder or grass ash to prevent wound infection.

The ④ ramet site should be clean, and the water for cleaning orchid plants should be sanitary. Do not use a basin of water to the end, and it is best to rinse with tap water; the washed orchid plants should not be exposed to the sun and should be put in the shade to dry.

Because the false bulb of ⑤ is too small and its nutrient storage is limited, it should not be planted too frequently. Generally, it is better to grow and raise 4-5 plants together. Except for a few strong grass with good root system and natural "road", it is generally not suitable for single plant.

⑥ as long as the pseudobulb of orchid is full and full and the root system is well developed, the strong grass can be cultivated in a single plant, such as 4-5 generation "symbiosis in the same house", but it is not conducive to growth and should be divided at the right time.

Generally speaking, most of the plant materials cultivated for more than two years are exhausted, so it is necessary to turn the pot and change the plant material in time, so as to meet the growth needs of orchids; but weak seedlings can appropriately prolong the years of turning pots, but turning pots too frequently is not conducive to the rejuvenation of orchids.

At this time, it is autumn, flower friends can choose the appropriate time to turn pots and ramets to start according to different temperatures in different places, which only provide reference, specifically according to the actual situation of their own orchids to operate, do not backfire.

The propagation method and management of potted orchids is one of the top ten famous flowers in China. It is loved by our people for its otherworldly temperament. This paper will briefly introduce the technology of split propagation of orchids. First, the conditions and timing are usually carried out in 2023 after planting, when the orchid plant has grown all over the basin; there are also those that split the conjoined orchid clusters with more than 4 plants in order to rapidly increase the number of varieties; and in order to prevent budding and plant degeneration, only one old and one new conjoined mother cluster was divided. The propagation of orchids can be carried out all the year round. According to its physiological characteristics, the best time is at the end of the flowering period, because the vegetative growth of the orchid plant is tired, not only the new bud has not germinated, but also the growth point of the bud has not yet expanded, and the ramet is not easy to cause accidental injury. At the same time, the flowering period is over, generally there will be no more flower buds, there is no problem of damage to flower buds due to ramets. In addition, through ramets, it can also promote the active vegetative growth and improve the resilience and germination rate of orchid plants. Second, methods and procedures 1, seedling: for the basin orchid that has grown all over the basin, do not pull it out forcefully when taking off the basin, otherwise the damage to the orchid plant is too great. Therefore, we should not hesitate to break the orchid pot and take out the orchid seedlings. Then shake off the matrix in the root cluster and cluster it. If the matrix is hardened or sticky, it can only be washed away with water before clustering. 2. Washing and drying the roots: it is best to wash the roots with tap water. Soaking is easy to infect bacteria. After the matrix is washed off, the orchid plant is spread out in the sun, cover the orchid leaf with a sunshade net, and turn the orchid root in the sun for two or three hours to make the orchid root soft and tough for ramet. 3. Ramet: because orchid plants are fond of clustering, they should be separated from the conjoined plants of the second or third generation according to their habits. 4. Cleaning and disinfection: when carrying out ramet reproduction, the decaying leaf tips and petioles should be cut off, and the wounds can be smeared with carbendazim and topiramate fungicides. Third, after the separation of planting and management, two points should be paid attention to when planting orchid plants: 1. Do not let the matrix containing base fertilizer near the wound of the orchid plant to prevent festering. The effective way is to use thick paper or thin plastic board to make a sleeve two or three centimeters smaller than the diameter of the orchid pot, cover the stem root and place it in the flowerpot, first fill the matrix without base fertilizer in the sleeve, and then fill the matrix with base fertilizer outside the sleeve, and then carefully take out the sleeve. two。 When the substrate is not dry, it can not be watered, and when the new roots do not grow, do not apply fertilizer as far as possible to prevent rotting roots. But foliar fertilizer or root promoter can be sprayed once a week. Foliar fertilizer and root promoter can also be diluted several times and sprayed the next day.
