Culture methods and points for attention of potted plant Cymbidium monophyllum (picture)

One-leaf orchid is an excellent shade-loving foliage plant for indoor greening decoration, also known as spider holding egg, Ruo leaf, bamboo leaf plate, Kowloon plate and so on. It is a perennial evergreen persistent herb of the family Liliaceae, which is native to various provinces and regions in southern China. Now it is cultivated all over China and is widely used. Let's take a look at the breeding methods and points for attention of one-leaf orchid.

Growth habits of Cymbidium mongolica

One-leaf orchid is mainly distributed in the provinces and regions of southern China, Hainan Island, Taiwan Island and so on, the rhizome is nearly cylindrical, with nodes and scales, leaves solitary, sexual preference for warm and humid, semi-shady environment, more cold-resistant, extremely shady. The suitable temperature for growth is 10: 25 ℃, while the range of growth temperature is 7: 30 ℃, and the overwintering temperature is 0: 3 ℃.

Cultivated varieties of one-leaf orchid

1. Variegated leaf orchid: spotted leaf orchid alias golden spider holding egg, spotted leaf spider holding egg, star spot spider holding egg, is a cultivated variety of one leaf orchid, with milky white or light yellow spots on the green leaf.

2. Golden leaf orchid: Golden leaf orchid alias golden spider holding egg, white spider holding egg, is a cultivated variety of one-leaf orchid, and there are light yellow vertical lines on the green leaves.

Ramet Propagation of Cymbidium chinense

1. Ramet time: the ramet propagation of Cymbidium can be carried out in combination with changing pots before the new buds germinate, usually after the soil is thawed in early spring (February and March).

2. Split method: take the mother plant out of the flowerpot, shake off the excess potted soil, separate the root system as much as possible, and cut it into two or more plants with a sharp knife. Each plant should have a considerable root system, and its leaves should be pruned properly to make each clump with 3 to 5 leaves, in order to survive.

Culture method of one-leaf orchid

1. Load the basin: soak the divided plants in 1500 times chlorothalonil for five minutes, then take out the cold and dry, and then serve. You can also irrigate the root with chlorothalonil immediately after potting.

2. Management: root irrigation or watering once after ramet potting, because the root system is greatly damaged and the ability of water absorption is very weak, it takes about 3-4 weeks to recover new roots, so it is necessary to control watering within 3-4 weeks after ramet to avoid rotting roots, but the transpiration of its leaves is not affected. In order to maintain the water balance of leaves, it is necessary to spray the leaves once or three times a day. Don't fertilize it these days. After ramet, we should also pay attention to the excessive sunlight, it is best to keep it in the shade shed.

3. Upper basin: first put a thick matrix of 2cm thick as a filter layer at the bottom of the basin, and then put in the plant. The substrate for the upper basin can choose one of the following. Peat: perlite: ceramsite = 2:2:1 or peat: vermiculite = 1:1 or peat: slag: ceramsite = 2:2:1 or sawdust: vermiculite: medium coarse river sand = 2:2:1 or vegetable garden soil: slag = 3:1 or garden soil: medium coarse river sand: sawdust = 4:1:2 or paddy soil, pond mud, rotten leaf soil, etc. After putting on the basin, pour water once and keep it in a shaded environment.

Maintenance technology of one-leaf orchid

1. Soil: Magnolia lanceolata is not strict on soil and resistant to barren, but it is better to use loose and fertile slightly acidic sandy loam. When potted, rotten leaf soil, peat soil and garden soil can be mixed in the same amount as substrate.

2. Moisture: the orchid should be fully watered in the growing season, keep the basin soil moist, and often spray water to the leaves to facilitate sprouting and growing new leaves, and the amount of water can be reduced appropriately after the end of autumn.

3. Lighting: one-leaf orchid can be cultivated in bright indoor all the year round, but it can not be placed in direct sunlight, either indoors or outdoors. Short exposure to the sun may also cause leaf burns and reduce ornamental value.

Summary: the breeding method of one-leaf orchid is introduced to you first. In fact, one-leaf orchid is very suitable for home and office layout, it can be watched alone, it can also be arranged with other flowering plants, and it is also a leaf material for modern flower arrangement. interested friends can then take a look at the breeding points for attention!

Matters needing attention in culturing Cymbidium mongolica

1. One-leaf orchid should be fully watered in the growing season, keep the basin soil moist, and often spray water to the leaves, so as to sprout and grow new leaves, and the amount of water can be reduced appropriately after the end of autumn.

2. In addition to controlling temperature and moisture, one-leaf orchid culture should pay special attention to whether it is sick or not, and cut off and burn the diseased leaves in time to reduce the source of infection.

3. Before the onset of the rainy season, spraying 50% Baig or Baogong wettable powder 1000 times, 25% carbon tetralin wettable powder. Once every 10 days, prevention and control 3 times 4 times.

4. Cymbidium is a shade-tolerant plant, the light should not be too strong, otherwise it will cause leaf yellowing or disease. Too much irrigation, especially in winter, can lead to root rot and leaf yellowing.

5. The maintenance of Euphorbia angustifolia in the greenhouse can increase the night temperature of the greenhouse, increase the ventilation time during the day, and reduce the humidity and fog duration in the greenhouse, so as to achieve the purpose of disease control.

6. In the peak growth period of spring and summer, one-leaf orchid is applied once or twice a month to ensure that the leaves are beautiful and bright, and can be cultivated in bright indoor all the year round, but no matter indoors or outdoors, they can not be placed in direct sunlight.

Prevention and control of diseases and insect pests of Cymbidium

1. Anthrax

[symptoms] the disease spots on the leaves of a leaf orchid often occur on the leaf edge or leaf surface. The lesion is nearly round, grayish white to grayish brown, the outer edge is yellowish brown or reddish brown, and there are small black dots arranged in a wheel in the later stage. In addition to leaves, petioles and stems are also infected, resulting in long streak spots. The pathogen overwinters in the soil or on diseased leaf tissue. Spread by airflow or water to carry out primary infection and re-infection. There are 2-3 peaks in the south and only one in the north. Continuous rainfall, heavy rainfall, serious disease.

[prevention and treatment] ① found diseased leaves and cut off and burned them in time to reduce the source of infection. Before the onset of the ② rainy season, spray 50% Shi Baig or Baogong wettable powder 1000 times liquid, 25% carbon tetralin wettable powder liquid. Once every 10 days, prevention and control 3 times 4 times. Spraying 0.5% potassium dihydrogen phosphate or 300 times of double-effect micro-fertilizer when necessary by ③ is beneficial to enhance disease resistance.

2. Grey mold

[symptoms] often occur at the edge of the leaf. Waterlogged disease spots began to appear from the leaf edge, and the disease spots expanded rapidly when the humidity was high, resulting in irregular withering of the leaf margin, and generally no gray mildew layer was seen. But after continuous overcast and rain, the humidity is high, the duration is long, and sparse gray mold can grow. The disease is easy to spread under the condition of high humidity and temperature of about 20 ℃.

[prevention and treatment] ① was carefully maintained and planted in a semi-shady environment with moist and good drainage. If sporadic diseased plants are found in ②, 65% metformin wettable powder 1000 times or 50% Sukeling wettable powder 1500 times, 50% Prohydantoin wettable powder and 50% Nongliling wettable powder 1000 times can be sprayed. The leaf orchid maintained by ③ in the greenhouse can increase the night temperature of the greenhouse, increase the ventilation time during the day, and reduce the humidity and fog duration in the greenhouse, so as to achieve the purpose of disease control.

3. Leaf spot

[symptoms] Leaf spot is also known as black spot, brown spot and so on. First of all, black spots appear in the middle of the leaves, and then the leaves turn yellow and fall off. The causes are mostly caused by muggy, unventilated and humid environment.

[prevention and control] pay attention to improving the environmental conditions, the damaged leaves can be removed and burned at the beginning of the disease. 1% Bordeaux solution can be sprayed for control, once every 7 days, a total of 5 times during the whole growth period, or 1000 times of 50% carbendazim.

What if the leaves of an orchid turn yellow?

1. the light is too strong

[reason] one-leaf orchid bogey is in direct sunlight, and short-term sunlight exposure may also cause leaf burns and yellowing, reducing ornamental value.

[methods] one-leaf orchid can be cultivated in bright indoor all the year round, but it can not be placed in direct sunlight either indoors or outdoors.

2. Too little light

[reason] one-leaf orchid is extremely shady and can be watched for months even in a dark room, but too dark for a long time is not conducive to the germination and growth of new leaves. If the light is too little in a dark place for a long time, the leaves will turn yellow.

[methods] if it is placed in a dark room, it is best to move it to a place with bright light for a period of time to facilitate growth and viewing, especially during the period from the germination of new leaves to the growth and maturity of new leaves.

3. Overwatering

[reason] overwatering is also one of the reasons why the leaves of Cymbidium are yellowing. Cymbidium likes water and has a certain tolerance, even if it is dry for several days, it will not die, but if too much watering will affect the root system absorption and cause the leaves to yellowing.

[methods] the watering of Cymbidium should be dry and wet, not too much, but not too little, and sufficient water is needed during the growth period.

4. Excessive fertilization

[reason] Cymbidium does not have a great demand for fertilizer, so it is best to apply light fertilizer each time. If too much fertilizer is applied, it will burn roots and destroy the growth of Cymbidium, and the leaves will turn yellow due to fertilizer damage.

[methods] dilute liquid fertilizer can be applied 1-2 times a month to promote the germination and robust growth of new leaves, to ensure that the leaves are beautiful and bright, and not to apply too much fertilizer.

5. Pest infection

[reason] Red spiders are very easy to appear in orchids maintained indoors, and insect pests are also the reason for the yellowing of leaves.

[methods] the two sides of leaves should be checked frequently, and triclofenac and nisolan should be sprayed in time.

The cultivation and Propagation of Cymbidium the morphological characteristics of Cymbidium mongolica

One leaf orchid (scientific name: Aspidistra elatiorBlume) because its fruit is very similar to the spider egg, also known as the spider egg. Orchid ornamental plant, perennial evergreen persistent herb, underground rhizome creeping spread; leaves drawn from the roots, erect upward growth, and long petiole, green leaves, will bloom. One-leaf orchid is evergreen all the year round, with beautiful leaves and strong growth, so it is an ideal indoor greening plant. Traditional Chinese medicine is used as a rhizome. The four seasons can be picked, dried or used freshly. Promoting blood circulation and dispelling blood stasis, tonifying deficiency and relieving cough.

The natural flowering period of one-leaf orchid is from March to May.

Ecological habits of Cymbidium mongolica

One-leaf orchid is native to the provinces and regions of southern China, and now it is cultivated all over the country and is widely used. Its nature likes warm and humid, semi-overcast environment, more cold-resistant, extremely shade-resistant. The suitable temperature for growth is 10 ℃ 25 ℃, while the temperature range for growth is 7 ℃ 30 ℃.

How to cultivate one-leaf orchid

Maintenance method of one-leaf orchid

The one-leaf orchid has strong adaptability and fast growth, and the basin should be changed every 1-2 years. Multi-purpose loam,

A culture soil in which rotten leaf soil and river sand are mixed in the same amount. When changing the basin, apply a small amount of broken bone slices or cake fertilizer as base fertilizer, pour through water and culture in a cool place after planting. During the growth period, water should be fully watered and often sprayed on the leaf surface to maintain high air humidity. Dilute liquid fertilizer can be applied twice a month to promote the germination of new leaves and robust growth.

Variegated varieties should be given light fertilizer, if the fertilizer is too sufficient, the leaf spots are easy to disappear. Avoid direct sunlight in summer, but pay attention to ventilation and remove yellow leaves in time. In the new leaf germination to the new leaf is growing stage, can not be placed in the shade of the room, otherwise the new leaf will grow slender and thin, affecting the ornamental. The northern region should move indoors in winter, reduce watering and stop fertilization, if the basin soil is too wet, it is easy to cause rotten roots.

The essentials of planting one-leaf orchid

One-leaf orchid is mainly propagated by individual plants. It can be combined with changing pots to split before the temperature rises in spring and the new buds have not germinated. The underground rhizome and leaves were divided into several clumps with 3-5 leaves in each clump, then planted in pots and maintained in semi-shady environment.

Magnolia lanceolata is not strict with the soil and is resistant to barren, but the loose and fertile slightly acidic sandy loam is better. When potted, rotten leaf soil, peat soil and garden soil can be mixed in the same amount as substrate. The growing season should be fully watered, keep the basin soil moist, and often spray water to the foliar surface to humidify. In order to sprout and grow new leaves, the amount of water can be reduced appropriately after the end of autumn. Liquid fertilizer was applied once or twice a month during the peak growth period in spring and summer to ensure that the leaves were beautiful and bright. It can be cultivated in bright indoor areas all the year round, but it can not be placed in direct sunlight, either indoors or outdoors; short-term sunlight exposure may also cause leaf burns and reduce ornamental value. Yilan is extremely shady, and can be watched for months even in a dark room, but being too dark for a long time is not conducive to the germination and growth of new leaves, so if placed in a dark room, it is best to move it to a place with bright light to maintain it for a period of time to facilitate growth and viewing. Especially during the period from the germination of new leaves to the growth and maturity of new leaves, they should not be placed in a too dark place.

The propagation mode of Cymbidium chinense

Ramet propagation

The leaf orchid is evergreen all the year round, the leaf shape is straight and straight, the leaf color is dark green and bright, the posture is graceful, elegant and elegant. At the same time, it has strong growth, strong adaptability and strong shade tolerance, so it is an excellent shade-loving foliage plant for indoor greening decoration. Suitable for home and office layout, can be watched alone, can also be arranged with other flowering plants, in order to set off the bright and beautiful of other flowers. It is very suitable for family breeding, when the family raises a leaf orchid, the ramet method can be used to propagate. During propagation, attention should be paid to the selection of ramet time, the application of ramet method and the maintenance after ramet.

Ramet time

The ramet propagation of Cymbidium can be divided in combination with changing pots before the temperature rises in spring and before the new buds germinate. It is usually carried out after the soil is thawed in early spring (February and March).

Ramet method

Take the mother plant out of the flowerpot, shake off the excess potted soil, separate the roots knotted together as much as possible, and cut it into two or more plants with a sharp knife. Each plant should have a considerable root system, and its leaves should be pruned properly so that each clump has 5 leaves in order to survive.

Disinfection in pots

Soak the split plant in 1500 times chlorothalonil solution for five minutes, then take out the cold dry, and then serve. You can also irrigate the root with chlorothalonil immediately after potting.

Management after ramet

Put the ramet into the basin and irrigate the root or water once. Because its root system is greatly damaged and its water absorption capacity is very weak, it takes about 3-4 weeks to recover new roots. Therefore, it is necessary to control watering within 3-4 weeks after ramet to avoid rotting roots, but the transpiration of its leaves is not affected. In order to maintain the water balance of leaves, it is necessary to spray the leaf surface one or three times a day (more spraying at high temperature, less spraying at low temperature or no spraying at low temperature). Don't fertilize it these days. After the split, but also pay attention to the sun is too strong, it is best to put in the shade to maintain.

Pot or transplant

At the bottom of the basin, a thick matrix of 2 cm and 3 cm was placed as the filter layer, and then the plant was put in. One of the following substrates can be used in the basin: peat: perlite: ceramsite = 2RV 1; peat: vermiculite = 1RU 1; or peat: slag: haydite = 2RV = 2v1; sawdust: vermiculite: medium coarse river sand = 2:2:1, vegetable garden soil: 3RU 1; or garden soil: medium coarse river sand: sawdust (slag) = 4RU 1RU 2; or paddy soil, pond mud, rotten leaf soil, etc. After putting on the basin, pour water once and keep it in a shaded environment.
