Two common propagation methods of orchids

The fragrance of orchids is pleasant, people have a very high evaluation of orchids through the ages, with the reputation of "gentleman in flowers", its roots, leaves, flowers, fruits and seeds have a certain medicinal value, so the economic value is very high. Friends who like orchids often want to breed their own orchids, so how on earth should they breed?

Orchid

I. split-plant propagation

It can be carried out in both spring and autumn, usually every three years. All plants with dense pseudocorms can be ramified, and at least 5 connected pseudocorms should be preserved in each clump. Irrigation should be reduced before dividing plants to make the basin soil drier. When putting on the basin after ramet, first cover the bottom hole of the basin with broken tiles, then cover the basin with coarse stones, occupy the basin depth of 5cm, 1ax, 4pm, then put coarse-grained soil and a small amount of fine soil, and then plant it with sandy loam rich in humus. Planting depth to the false bulb just buried in the soil strength, the edge of the basin left 2cm along the mouth, covered with green cloud grass or fine stones, finally watered thoroughly, placed in the shade for 10 to 15 days, keep the soil moist, gradually reduce watering, and carry out normal maintenance.

2. Sowing and propagation

The orchid seed is very fine, there is only one underdeveloped embryo in the seed, the germination power is very low, and the seed coat is not easy to absorb water, so it can not germinate by conventional sowing, so it needs to use orchid or artificial medium to supply nutrients in order to germinate. Sowing it is best to choose uncracked fruit, after the surface is sterilized with 75% alcohol, take out the seed, soak it with 10% sodium hypochlorite for 5 minutes, rinse it with sterile water for 3 times, sow it in a culture bottle containing culture medium, then place it in a dark culture room, keep the temperature about 25 ℃, germinate and move to light to form protocorm. It takes half a year to a year from sowing to transplanting. Tissue culture has been successful, and this method can be used to propagate where possible.

How to reproduce orchids, the methods of division, sowing and propagation of orchids

Orchids are very common potted plants at home, there are many varieties of orchids, and the ornamental value is very high, so there are many flower friends who cultivate orchids, and it is not difficult for orchids to breed, but orchids need some skills to reproduce. I hope it will be helpful to the flower friends who raise orchids.

Propagation techniques of Orchid

Common methods of ramet, sowing and tissue culture propagation of orchids

1. Propagation methods of orchids.

It can be carried out in both spring and autumn, usually every three years. All plants with dense pseudocorms can be ramified, and at least 5 connected pseudocorms should be preserved in each clump. Irrigation should be reduced before dividing plants to make the basin soil drier. When putting on the basin after ramet, first cover the bottom hole of the basin with broken tiles, then cover the basin with coarse stones, occupy the basin depth of 5cm, 1ax, 4pm, then put coarse-grained soil and a small amount of fine soil, and then plant it with sandy loam rich in humus. Planting depth to the false bulb just buried in the soil strength, the edge of the basin left 2cm along the mouth, covered with green cloud grass or fine stones, finally watered thoroughly, placed in the shade for 10 to 15 days, keep the soil moist, gradually reduce watering, and carry out normal maintenance.

2. Methods of sowing and propagation of orchids.

The orchid seed is very fine, there is only one underdeveloped embryo in the seed, the germination power is very low, and the seed coat is not easy to absorb water, so it can not germinate by conventional sowing, so it needs to use orchid or artificial medium to supply nutrients in order to germinate. Sowing it is best to choose uncracked fruit, after the surface is sterilized with 75% alcohol, take out the seed, soak it with 10% sodium hypochlorite for 5 minutes, rinse it with sterile water for 3 times, sow it in a culture bottle containing culture medium, then place it in a dark culture room, keep the temperature about 25 ℃, germinate and move to light to form protocorm. It takes half a year to a year from sowing to transplanting. Tissue culture has been successful, and this method can be used to propagate where possible.

Seed sowing and propagation techniques of orchids 1. Site selection

It is required to be open, well ventilated, close to the water surface, moist air and no soot pollution. In the southwest of the site, evergreen broad-leaved trees can be planted, and the canopy density should be about 0.7, which can reduce afternoon sun exposure and adjust humidity and temperature.

2. Orchid seed sowing

The orchid seed is very fine, there is only one underdeveloped embryo in the seed, the germination power is very low, and the seed coat is not easy to absorb water, so it can not germinate by conventional sowing, so it needs to use orchid or artificial medium to supply nutrients in order to germinate. Orchids are best sown with uncracked fruits, sterilized with 75% alcohol on the surface, and then take out the seeds.

3. Orchids split pots

After the basin is full, the basin is divided, usually once every 2-3 years, from March to early April (Qiulan), or from October to mid-November (Chardonnay orchid, Chunlan). When dividing the basin, the basin soil should be drier. If it is wet mud, it is inconvenient to operate, and it is easy to break and hurt the root. After the mother plant is turned out, gently remove the mud.

4. Orchids in pots

Flowerpots with small mouth, deep pot, large bottom hole is better. Wild seedlings newly dug up from the mountains must be planted in tile pots and cannot be replaced into purple sand basins or porcelain pots after 3 years. First, cover the hole at the bottom of the basin with clam shells, brown slices, etc., and add coarse sand, cinder and charcoal to form steamed bread, accounting for about 1x3. The thickness of the culture soil is about 3mi 5cm. There is usually no base fertilizer. Then put the orchid into the basin, arrange the roots densely, add the fine soil until it is 3cm away from the basin, lift the orchid plant slightly, and the height is flush with the soil surface at the top of the pseudobulb, not too shallow or too deep. Gently press the basin soil so that the soil is in close contact with the root, and then use your fingers to compact around the basin so as not to cause voids when watering.

5. Watering

It is appropriate to use Rain Water or spring water. Saline-alkali water should not be used. If tap water is used, the water should be shelved for several days. Watering depends on the air temperature, the amount of water should be less in spring and more in summer; the plum rain season is when the orchids sprout leaves, and the basin soil should be slightly dry; the weather turns cool after autumn, and the amount of watering should be reduced to keep it moist. It is suitable to dry indoors in winter, reduce the watering times, and be watered at noon. Orchids can be caught in light rain, but continuous rain or torrential rain is prone to rotten hearts and rotten leaves, so pay attention to rain prevention.

6. Fertilization

Plant orchid should use cake fertilizer, mix well with 4 parts of plant ash, 10 parts of bean cake and 10 parts of bone powder, put them in the jar, add water several times, soak the bean cake until it is soaked, then cover and seal, after one year of ripening, and then make into dry grains. Just put it on the basin when you use it. If whole dung is used, it should also be matured for one year and diluted with water. Generally began to fertilize in May, to the Beginning of Autumn stop fertilizer, master more thin fertilizer. Fertilization should be carried out in the evening, and fresh water should be watered again the next morning.

7. Sun shading and cold protection

Except in early spring and winter, it should be placed under the open shed. The shade shed is required to be well ventilated. Orchids can bask in the sun when they just come out of the room from March to April, and the shade time will increase gradually. In winter, orchids should be moved indoors against cold and kept at room temperature for 1-2 ℃. In addition, after the orchid leaves the house in spring and before entering the house in autumn, you should pay attention to frost prevention.

Common propagation methods of white orchids the white orchids are commonly used for striping and grafting propagation. The striping was kept moist by high-altitude pressing from June to July, and took root about 2 months later. Grafted with two-year-old Magnolia as rootstock, the branches of white orchid with the same thickness as rootstock were selected in the plum rain season, then healed in 60-70 days and cut off from the mother plant to form seedlings. White orchid can be propagated by grafting, striping, cutting, sowing and other methods, but the most commonly used are grafting and striping. In the method of grafting, there are two kinds of grafting, one is leaning grafting, the other is cutting grafting. Connecting: depending on the time, from spring to autumn, the whole growing season can be carried out. Most of them are carried out from April to July. The best place to lean on is 70 cm from the ground. After being tied up, it is wrapped in a mass of mud and wrapped in leaves to prevent Rain Water from scouring. It can be cut off after about 60 days. Grafting is an easier way to survive, but it is not as exuberant as cutting. This article comes from: http://www.yuhuagu.com striping propagation also has two kinds: ordinary crimping and college crimping. ① ordinary striping: the pressing is best carried out in February to March, cut the base of the branch to be taken into half the depth, then cut up a section, and then stick a tile in the middle, then gently press into the soil without breaking, insert it into the soil with "U"-shaped thick wire, fix it, prevent it from warping, and then pile it on the soil. After the root bud is sent out, the strip can be cut off and planted in spring. ② high branch crimping: select robust and disease-free twigs (1.5-2cm in diameter) on the mother plant before volley, cut the cracks in the lower part of the basin fork, then cover it with bamboo tube or bottomless clay pot, fill it with culture soil, tie it tightly with string outside, be careful not to touch it, often spray a small amount of water, keep moist, and grow new roots around May of the following year.
