How to water a leaf orchid? a leaf orchid needs to be watered every few days / the soil is moist.

We know that watering is the key factor in the cultivation of Cymbidium, but too much watering will rot the roots, and too little watering is not conducive to the germination of new buds, so how to water it properly? How many days does it take to water a leaf orchid? The editor came to give answers to the flower friends one by one.

How to water a leaf orchid

In terms of water quality, the requirements of one-leaf orchid are relatively relaxed, but the most suitable water quality is river water, well water, Rain Water, and so on. These water is rich in minerals, which is beneficial to the growth of one-leaf orchid. Of course, tap water can also be used. When watering, it is necessary to dry and wet alternately and fully moisturize in order to promote growth.

A leaf orchid needs to be watered every few days.

1. One-leaf orchid is watered in spring

Spring is the exuberant period for the growth of one-leaf orchid, how to water it at this time? Generally irrigate once every two days, according to the moist condition of the soil, choose the watering time, if it is the spring plum rain season, Rain Water can be used to irrigate, it is one of the most suitable water quality for the growth of Cymbidium.

2. One-leaf orchid is watered in summer

Watering in summer must be cautious, usually once a day, watering time is best in the morning, avoid watering at noon high temperature, easy to lead to water evaporation too fast, too little water is absorbed. In addition, it is also necessary to spray water on the leaves to avoid yellowing of the leaves.

3. Watering in autumn

Autumn is a transformation process from fast to slow growth, so watering should be from more to less. It can be watered every 2 days at the beginning of autumn and 3-4 days at the end of autumn, which should be judged according to the condition of the soil.

4. Is the leaf orchid watered in winter

Many plants go into dormancy when the temperature is low in winter, and one-leaf orchid is no exception, but although it grows slowly in winter, it also needs watering. How to water one-leaf orchid at this time? Generally watered once a week or so, warm water can be used when watering, the amount of water is not too much, it is generally OK at ordinary times.

Can the leaf orchid be watered after changing the basin?

When introducing how to make a leaf orchid burst the basin, we emphasize the importance of changing the basin. After changing the basin, watering is very important. After changing the basin, it should be watered thoroughly, and then watered every 3-4 days until the leaf orchid returns to normal growth. Then water it timely according to the moist condition of the soil.

What if the leaf orchid is watered too much?

When we are watering, what should we do if we accidentally water too much? The answer is to drain the stagnant water quickly, and check whether the soil is well drained, and to see if the drain hole is blocked, so that the roots cannot be soaked in the water for a long time.

How to cultivate one-leaf orchid cultivation techniques and matters needing attention

One-leaf orchid, also known as spider egg, belongs to orchid family flowering plants, perennial evergreen persistent herbs, evergreen all the year round, beautiful leaves, strong growth, is a very popular family potted plant. Today, the editor will tell you how to cultivate Cymbidium, as well as its cultivation techniques and matters needing attention.

The introduction of one-leaf orchid

One leaf orchid (scientific name: Aspidistra elatior Blume) 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. For fall injury, rheumatism muscle pain, low back pain, lung deficiency cough, hemoptysis effect.

1. Morphological characteristics

Rhizome: one-leaf orchid is a perennial evergreen herb. Rhizome subTerete, 5-10 mm in diam., articulate and scaly.

Leaves: leaves of a leaf orchid solitary, 1-3 cm apart, rectangular-circular-lanceolate, lanceolate to subelliptic, 22-46 cm long, 8-10 cm wide, apex acuminate, base cuneate, margin ±crisped, green on both surfaces, sometimes with slightly yellow-white spots or stripes; petiole conspicuous, stout, 5-35 cm long.

Flowers: total pedicel of one-leaf orchid 0.5-2 cm long; bracts 3-4, of which 2 are located at the base of the flower, broadly ovate, 7-10 mm long, ca. 9 mm wide, light green, sometimes with purple spots; perianth campanulate, 12-18 mm long, 10-14 mm in diam., purplish or dark purple outside, lavender or dark purple on the lower part of the inner surface, 6-lobed in the upper part; perianth tube 10-12 mm long. Lobes subtriangular, 3.5-4 mm wide, apex obtuse, margin and upper part of the medial light green, inner surface with particularly thick fleshy ridges, 2 thin and long in the middle, 2 thick and short on both sides, 1.5 mm high in the middle, purplish red; stamens 6-8, arising from perianth tube near base, below stigma; filaments short, anthers elliptic, ca. 2 mm long Pistil ca. 8 mm tall, ovary hardly inflated; style jointless; stigma peltate-dilated, orbicular, 10-13 mm in diam., purplish red, 3-4-parted on top, both sides of crack more or less protruding, central part slightly convex, lobe apex retuse, margin often curled upward.

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

2. Ecological habits

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 ℃.

Cultivation techniques of one-leaf orchid

I. maintenance methods

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.

2. Planting essentials

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.

Third, the mode of reproduction-- 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.

The main results are as follows: 1. Ramet time: the ramet propagation of Cymbidium can be combined 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).

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, so that each clump has 5 leaves in order to survive.

3. Disinfection in a basin: soak the divided plants in 1500 times chlorothalonil solution for five minutes, then take out and dry, and then put on the basin. You can also irrigate the root with chlorothalonil immediately after potting.

4. The management after ramet: after filling the pot, the ramet is irrigated with root or watered 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.

5. Pot or transplant: first put a thick substrate of 2 cm and 3 cm thick in the pot bottom as a filter layer, and then put in the plant. 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.

Matters needing attention in the Culture of Cymbidium

One-leaf orchid is a perennial evergreen herb, rhizome coarsely creeping. Leaves basal, hard, narrow base into a groove, long petiole, leaves up to 70 cm long. Flowers solitary, short pedicel, attached to the ground, flowers about 2.5 cm in diameter, brownish purple, flowering from April to May. The one-leaf orchid has a dark green color and a unique leaf shape, which is an excellent viewing and modeling material in indoor potted plants and flower arrangement. In addition to controlling temperature and moisture, one-leaf orchid culture should also pay special attention to whether it is sick or not.

1. Cut off and burn the diseased leaves in time to reduce the source of infection.

2. Before the 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.

3. Choose the semi-shade environment with moist and good drainage. 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.

4. The leaf orchid maintained in the shed can increase the night temperature of the shed, increase the ventilation time during the day, and reduce the humidity and fog duration in the shed, so as to achieve the purpose of disease control.

Origin and habits: Euphorbia is native to Hainan Island and Taiwan in China. Nature likes warm, wet, barren, not cold-resistant, like loose, fertile, well-drained sandy loam.

Propagation and cultivation: propagation is mainly based on ramet, which can be combined with soil change in spring, and the dense plant cluster can be divided into 2 ~ 3 leaves and planted in one cluster. Sufficient water is needed during the growing period, the cultivation environment should be overcast and wet, it should be maintained under the shade in summer, and it can survive the winter safely if it is more than 0 ℃ in winter. Nitrogen fertilizer is the main fertilizer, and dilute liquid fertilizer can be applied twice a month. One-leaf orchid has strong resistance, while waterlogging is easy to infect diseases and insect pests.

Disease control of one-leaf orchid

1. Anthrax

Symptom characteristic: the disease spot on the leaf of one leaf orchid mostly occurs in 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 control methods:

① found that diseased leaves were cut off and burned 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: it often occurs 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. Botrytis cinerea uses hyphae to rot in the remains of the disease, and constantly produces conidia for re-infection. The survival time of sclerotia is long, if there are suitable conditions, hyphae grow, directly invade or sputter by Rain Water or spread with disease remains, water flow, farm tools and so on. The disease is easy to spread under the condition of high humidity and temperature of about 20 ℃.

Careful maintenance of ①

Choose the semi-shade environment with moist and good drainage. 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.

If sporadic diseased plants are found in ②

It can be sprayed with 65% metformin wettable powder 1000 times or 50% Sukeling wettable powder 1500 times, 50% Prohydantoin wettable powder, 50% Nongliling wettable powder 1000 times.

One-leaf orchid maintained by ③ in the greenhouse

Measures can be taken to increase the night temperature of the shed, increase the ventilation time during the day, and reduce the humidity in the shed and the duration of fog, so as to achieve the purpose of disease control.

3. Leaf spot

Cymbidium leaf spot often occurs in natural distribution and introduction areas, which mainly harms leaves and reduces ornamental value. The primary waterlogged small necrotic spot on the damaged leaf surface, and then gradually expanded into a brown spot with a diameter of 2~3mm, surrounded by a yellow halo. The pathogen is fungus, Cladosporium. The pathogen overwintered with mycelium in diseased leaves or ground diseased bodies, and the disease could occur in spring, summer and autumn. Disease spots can be seen in northern greenhouses or rooms with heating in winter.

(1) symptom characteristics: 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.

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.

Culture methods and matters needing attention of Cymbidium chinense

One-leaf orchid is a beautiful foliage plant, it is a kind of Liliaceae, the leaves are evergreen all the year round, can be made into pots to be placed at home, can beautify the environment and purify the air at the same time. So how should one-leaf orchid be raised? Today, I will tell you all the breeding methods and matters needing attention of one-leaf orchid. Friends who like to send flowers, come and have a look.

Culture methods and matters needing attention of Cymbidium chinense

1. The culture environment of one-leaf orchid.

The vitality of the leaf orchid is relatively strong, the requirement to the environment is not high, it likes the warm and humid semi-shady environment, the cold resistance is relatively strong, usually produces the fastest in the environment of 10 to 25, usually can put it in the living room, move it to the balcony every few days, accept the right amount of sunlight.

2. The requirements for soil quality of Cymbidium chinense.

Magnolia does not have high requirements for soil quality, and its poor resistance is very strong, but attention should be paid to preparing loose, fat and living basin soil for it. The soil quality is preferably acidic, and the sandy soil is the best. When making basin soil, rotten leaf soil and peat soil can be mixed in a ratio of one to one.

3. The requirement for fertilizer and water of Cymbidium mongolica

One-leaf orchid has a relatively high demand for water in the growing season. It can be watered every two days, but it can not be watered thoroughly, but stagnant water can not appear in flower poverty. In addition, one-leaf orchid will grow faster in spring and summer, so it is necessary to apply fertilizer in time. It is best to apply fertilizer twice a month, mainly cake fertilizer, and timely watering after fertilization, and the amount of fertilization should not be too much. Otherwise, there will be bad symptoms such as rotten roots or yellow leaves.
