Here are some introductions to the orchid

Cymbidium Kanran, Orchidaceae.

Scientific name: Cymbidium Kanran Mak.

Distributed in Fujian, Zhejiang, Jiangxi, Hunan, Guangdong and other places, Japan also has distribution. It is not well known in China, but it is very popular in Japan and Korea. "Japanese cold orchid" is Japan's original orchids in the strongest aroma. This species has multiple flowers on one stem and elegant and noble leaves, and it is the only king of orchids native to Japan. Therefore, Japanese orchids occupy a prominent position in the Japanese orchid world. In the orchid market, the price is also high.

The shape of Japanese orchid is very similar to that of Jianlan, but the leaf blade is thinner, especially at the base, and the posture of the leaf is dashing, which makes it look elegant and noble. The leaves are 3～7 in a cluster, erect, 4D～70 centimeters long, 1～1.7 centimeters wide, all green or with fine teeth near the top, slightly glossy. Scape erect, as high as or above the leaf surface, sparsely flowered, with more than 10 flowers. The petals and sepals are narrow and slender, and the flowers are richly colored with yellow-green, purple-red, and deep purple, usually with mixed veins and spots. Flowering period from October to December, frost and cold spitting fragrance, is really valuable, so there is a "cold orchid" name. The fragrance of the flowers is strong and long-lasting.

Cold orchids are afraid of heat and cold, so they are cultivated in the south and managed in a cool environment, and the color of their perianths is usually used to divide them into variants. There are the following four kinds: ① green cold orchid; ② green and purple cold orchid; ③ purple cold orchid; ④ red cold orchid. Among them, green orchid and red orchid are precious. The so-called plain cold orchid produced in Taiwan, with light green flower color, belongs to the type of green cold orchid. So far, the number of plain cold orchids is very small and the price is very expensive. Its famous products are "Cold Fragrance Vegetable", "Broad Cold Vegetable" and "Cold Mountain Vegetable". In Japan, the famous products are "Yumo" and "Toyosetsu". The famous red orchid is "Nikko", all of which are rare and precious. In addition, the line art of orchids is found in Taiwan and Japan, but the number is very small. In Taiwan Province, only "Mushan Huang" is successfully cultivated as a rare orchid.

According to the report of Mr. Peng Shuang-Song from Taiwan, the two natural hybrids "Su-Lu Cold Orchid" and "Chun-Lu Cold Orchid", which are related to Cold Orchid, were discovered only in the last thirty years, and they have been cultivated by many orchidists in Taiwan. The origin of "Sulu Orchid" is that in 1959, Japanese found an orchid similar to Taiwan Orchid at an altitude of about 1,000 meters near Sulu She of the Alpine Compatriot Tribe in Tai'an Township of Miaoli County, so they took the orchid back to Japan for cultivation, and then it blossomed in the period of Annunciation Orchid, and the petals were fatter than that of the orchid. The petals were fatter and broader than the orchid, so it was realized that it was a natural hybrid between the Taiwan Cold Orchid and the Taiwan Frost Orchid, and was named "Sulu Cold Orchid". After its publication, it was widely loved by Japanese orchidists. The leaf shape of this species is similar to that of the orchid, so the only way to identify it is by its flowering period and flower shape. Since it is a first generation hybrid, it has strong fertility and is easier to cultivate than the Cambrian Orchid, and because the flowers are larger than both parents, the buds are full of variations, and the flowers are fragrant, it has been popularized rapidly in Taiwan and Japan, and more and more people are cultivating it. Another kind of "Chunhan Orchid" is a natural cross between Taiwan Broadleaf Spring Orchid and Taiwan Cold Orchid, which is produced in the Pinglin Mountain area of Taipei, the Miaocai Mountain area, and Hualien and other places. This species has dark green leaf color, smooth leaf surface similar to the cold orchid, but the leaf posture is shorter than the cold orchid, the leaf length is 30-50 centimeters, the leaf width is 0.6-0.9 centimeters, the scape is 20-25 centimeters, usually one to two, the diameter of the flower is 5-6 centimeters, the color of the flower is brown or purplish-brown, the flower has a strong fragrance similar to the spring orchid, and the flowering period is the same as the year-end orchid. The rare product is named "Ode to Spring".

Somewhat like hyacinth /i?ct=201326592&cl=2&lm=-1&tn=baiduimage&pv=&word=%B7%E7%D0%C5%D7%D3&z=0

Somewhat like hyacinth. I found some pictures.

A, cultivation techniques

Like sunny and relatively moist environment, requires well-drained and fertile sandy loam. More cold hardy, in the winter warmer areas of the fall rooting, early spring new shoots out of the ground, March flowering, late May fruit ripe, early June above ground part of the withering and enter dormancy. In the dormant period of flower bud differentiation, differentiation temperature 25C or so, differentiation process of about 1 month. After the flower bud differentiation to the elongation of growth before there should be about two months of low temperature stage, the temperature can not exceed 13C. commercial bulbs flower buds have been differentiated.

Hyacinth should choose a well-drained, not too dry sandy loam is appropriate, neutral to slightly alkaline, before planting to apply sufficient fertilizer, field cultivation, avoid continuous cultivation. Cultivation methods are open field cultivation, potting, enabling cultivation and water.

1. open field cultivation It is suitable for October to November, choose a well-drained soil is the most important condition. Planting before the application of adequate fertilizer, the top with a thin layer of sand, then the bulbs in rows, spacing 15 cm to 18 cm, mulch 5 cm to 8 cm. And mulch to keep the soil loose and moist. Generally no other management before flowering, after flowering, if not intended to collect seeds, should be cut off the flower stalks to promote the development of bulb, cut off the location should try to in the flower stalks of the uppermost. early June can be dug out of the bulb, spread out, graded storage in the cold storage, the temperature should not be more than 28 degrees Celsius in the summer.

2. pot planted in late fall from the market to select well-grown hyacinth bulbs, planted in loose culture soil. The number of bulbs planted depends on the size of the pot, generally 1 to 3 ranging. Loam, leafy soil, fine sand and other mixed for nutrient soil, generally 10 cm caliber pots planted a ball, 15 cm caliber pots planted 2 to 3 balls, and then the pots buried in the soil, covered with soil 10 cm to 15 cm, after 7 to 8 weeks, the buds grow to more than 10 cm, go to the soil to make the sunshine, generally planted in October to November, flowering in March. Planting should be noted: the upper end of the bulb should be exposed to the potting soil, after planting should be placed in the sun, and to keep the potting soil moist. The temperature requirement for flower promotion is 5~10℃.

3. Water cultivation Cultivation containers can choose the bottle mouth slightly smaller than the bulb of the glassware, will be placed on the mouth of the bottle, add water to about 1 cm away from the bulb disk, pay attention to do not make the bulb disk immersed in water, and then placed in a dark place, to promote the bulb disk rooting. Change the water once every 4 days. When the new roots into the water, and began to grow new leaves when moved to the light, scape flowering. You can also take like daffodils, several bulbs planted together in a shallow pot for hydroponics.

4. Cultivation After late July, the bulb is treated with 8C low temperature for 70 to 75 days, and then potted in early October, cultivated in the greenhouse, can make it bloom at the end of the year. Since cultivars differ greatly in their ability to produce flowers, it is important to select cultivars that are suitable for producing flowers when cultivating them.

Cold Orchid planting:

One, planting

Cold Orchid grows in the dense broad-leaved forests on steep slopes, with little light, shallow roots, and a thin layer of humus covering the roots, with good water permeability. Therefore, when planting the choice of tall purple sand pots, the bottom one-third of the pot with coarse particles of bricks, Styrofoam block padding, the middle of the hemp mushroom mud, coarse wood chips, weathered stone, plant gold stone, pond bedrock, soybean-sized bricks and mixing to one-third of the pot, the upper part of the size of the weathered stone, brick particles mixing and a small amount of humus can be. The planting requires loose, breathable, water-friendly, and strong insulation properties. Particular attention should be paid to the simple use of hard planting material, wood chips, humus, etc., survival rate, seedling rate, flowering rate are not high.

Two, cultivation

Cold orchids because of its growing environment and spring cymbidium orchids have differences in cultivation methods should be slightly different. Firstly, the shade and temperature are similar to that of Melaleuca alternifolia. Especially in the high temperature season with strong light, more attention should be paid to shade and moisturizing. In addition, every morning or evening of sunny days should be sprayed with leaf water, and the shading degree reaches about 80%. In this way, the leaf texture is glossy, and the disease is less; I put the cold orchid under the orchid shelf in the high temperature season, and there are spring orchids and cymbidium orchids on the shelf to block the light, and the effect is quite good. Secondly, prevent wind and frost. In the fall and winter period, avoid strong wind and cover it on frosty days. Third, fertilization. Cold orchids planted according to the above plant materials can generally be fertilized less or even not, or can be sprayed with nitrogen-containing fertilizers, such as Hanabao No.4, B1 germination agent, etc., on the foliage from April to June. fertilizers containing phosphorus and potassium can be sprayed during August to October, such as blooming fertilizer, Hanabao No.3, potassium dihydrogen phosphate, etc.

Three, maintenance

Can cold orchids bloom, good flowers, fragrance, maintenance is very critical. If dark-colored flowers, the light should be a little stronger, and the vegetative ones a little more shady. The flower arrows start to pull up to the flowering before, if you do not pay attention to planting, buds are easy to stiff rot off. For this reason, the buds of orchids are easy to be attached by mites, the insect pests are similar in color and color to the buds, a path found not timely control, the flowers will not bloom. Therefore, it is necessary to spray the drugs such as Flower Health No.1 and Permethrin to prevent and control it effectively. In order to cold orchids out of the fragrance more clear, show flowers period should be more sunshine, so that, even at night, will be fragrant.

1, spring, rain, spring orchids have been flowering, the soil should not be too dry, along the pot of fruit slightly wet; autumn orchid pots such as not dry to the bottom, do not water.

2, hibernation, spring orchid pots dry to half pot (empty under the real), you can run water, but should not be more, autumn orchids with the same before.

3. On the vernal equinox, spring orchids have already lost their flowers, so they should avoid humidity, and can be moistened when their pots are half-dry.

4. Ching Ming and Grain Rain, do not make the potting soil too dry, and moisten the water every 5 days.

5, summer, orchids began to come out of the room, it is appropriate to water thoroughly once.

6, small full, potting soil should not be too dry and too wet, leaf spot that is too wet, new shoots withered tip that is too dry, every 4 days to water a liter (about dry tea cup), so that the potting soil from the bottom to the top of the 2/3 wet is appropriate.

7, mango, the climate is dry, it is more appropriate to pay attention to do not too dry too wet.

8, summer solstice, the potting soil from too dry, in case of heavy rain, can only tolerate a day, such as the rain need to move the pot to a ventilated place.

9, summer, the air is too humid, the potting soil can not be too wet, pots should be placed in a ventilated place, if the dry heat and less rain, every 2 days watering a liter, heavy rain or a big wet, must be dry to the potting soil 2/3, otherwise it is not suitable for watering again.

10, summer, the potting soil is easy to dry to the end, need to pay attention to the daily rain or wet only once.

11, autumn, orchids in this time is in need of water, every 3 days need to water 2 liters, and it is advisable to avoid the wind for a second.

12, the department, every 5 days watering, except for the hazy rain, can be subjected to rain and dew.

13. At white dew, autumn orchids need to be watered more diligently than spring orchids, but after the water is wet, they must be dried up before they can be wet again.

14. At the autumnal equinox, if the orchid has already produced flowers, it should be watered slightly less; if it has not produced flowers, it should be watered slightly more.

15. At the cold dew, autumn orchids should be watered thoroughly, while spring orchids should not be watered thoroughly.

16. Frost, orchids should be put into the room, the watering time should be changed to the middle of the day, and the orchids should be exposed to the sun for 1-2 hours after watering.

17. In winter, it is only appropriate to moisten the water, about half a liter every 5 days.

18, snow, flower room avoid warm, not too wet, if too wet can cause root rot, scarring leaves to wither, if the pot is not dry to the bottom, only slightly wet soil skin.

19, snow, autumn orchids do not need water, spring orchids should be slightly moist

20, winter solstice, should not be irrigated.

21. Watering is not recommended in cold weather.

22. In the cold season, water is still not needed for autumn orchids, and spring orchids can be slightly moistened with water.

V. Fertilization

Orchid fertilization depends on the growth of orchids. Where the growth of lush and disease-free can be fertilized, the growth of poor, can not be fertilized or a small amount of fertilizer. Newly dug from the mountains of orchids before the new roots are not fertilizer, need to be 1-2 years of cultivation, to be the new roots flourish before fertilizer, otherwise easy to wither.

Generally speaking, in June-July when the orchid leaf buds elongation of about 1.5 cm, you can apply 1-2 times of thinly rotted liquid fertilizer (should not be used fertilizer), but in the hot season should not be fertilized. By August-September, apply 1-2 times of thinly rotted liquid fertilizer again. Vegetative heart species of orchids, can be applied 1-2 times grass ash leachate, the effect is very good. Fertilizer time in the evening is the best, the next day early in the morning and then water.

The easier way to tell if an orchid needs fertilizer is to look at the shade of the leaves. Leaves are yellow and thin is a lack of fertilizer, should be fertilizer; leaves are black and the tip of the leaf is scorched is too much fertilizer, should stop fertilizer.

Fertilizer, can be used in a variety of ways described above homemade fertilizer. Application of these fertilizers, need to add water 8-9 times diluted, not too thick. Fertilizer should be applied to the plant's inter-root, do not apply to the foliage. Orchids main fertilization times and dates

Number of times Date category First Second Third Fourth Remarks

Spring orchids late June mid-July mid-August mid-September Fourth time to be especially thin

Summer orchids late June mid-July mid-August mid-September Fourth time to be especially thin

Autumn orchids early June late June mid-July mid-August fourth time to be especially thin

Autumn orchids early June late June late July late August The fourth time to be especially thin

Sixth, pruning

In the orchid cultivation should be constantly pruning. In the old leaves withered and yellowed should be cut in time to facilitate ventilation, some leaves of the tip of the leaf dry should also be cut. In particular, there are diseases and insect infested leaves need to be removed in a timely manner to avoid contagion. When cutting the leaves of virus disease, the scissors used should not come back to cut the non-diseased leaves to prevent virus transmission. If the same scissors are used, they need to be sterilized.

After the flower buds of valuable orchids come out of the ground, if there are too many flower buds, you should keep the strong buds and remove the rest of the thin flower buds, and it is appropriate to keep 1-2 flower buds in each pot. If there are too many flower buds, it will not only make the flowers bloom well, but also consume too much nutrients from the mother plant to affect the next year's blooming. General orchids may not cut the flower buds.

Spring orchid flowers, about half a month, that is, the flowers need to be cut off; summer orchid flowers, to the last one on the inflorescence after the opening of a week, should also be cut off the inflorescence. Valuable varieties should not be pollinated and fructified, otherwise the flowering of the following year will be affected. If as a cross-breeding, the other need to be cultivated with care, so that the fruit is full and ripe.

VII. Cold protection

Autumn orchids should be protected from cold early, such as when the temperature is 2-3℃, they can be moved indoors. Cold orchids growing in the south need to be protected from cold earlier. Spring and summer orchids are more cold-tolerant, but they should be moved indoors in time if freezing occurs. Room temperature can be maintained at 1-2℃ for overwintering. In case there is a serious cold spell, room temperature drops below zero, need to be timely heating, generally can keep the room does not freeze on the good.

Inside the room, fall orchids need to be placed on the side facing south, spring and summer orchids on the other side. Around noon, the south and southeast facing side should be ventilated by opening the window (autumn orchids should not open the window on cloudy days with 1-2℃ Celsius, in order to prevent the cold wind from freezing the leaves). Autumn orchids like to dry some in winter, the rest of the orchid potting soil should be kept moist.

VIII. Flower plucking

For orchids with poor growth, each clump of leaves is not much, or the roots are not good, flower plucking should be carried out. For better varieties, 1-2 buds can be removed appropriately for spring orchids, and 1-2 buds should be kept for summer orchids when the buds are elongated, and the rest can be removed so that the flowers can bloom for a longer time, and the new leaves can be pumped more, and the old ones will not be easy to wither and die.

Famous spring orchid flowers should be removed 3-5 days, so that the growth of leaf buds strong; summer orchid flowers to the top of a flower can also be cut from the basin surface centimeters.

Nine, flood control

Cultivation places such as open surroundings, high terrain, summer gales or typhoons, need to do a good job of windproof work, so as to avoid the leaves of summer orchids or cold orchids are broken.

Ten, spray

Dry season, every evening in the placement of potted flowers on the balcony for spraying, mainly to make the ground wet, increase air humidity. Orchid pot surface should also be sprayed. Spraying should be sprayed upward, so that the fog point falls fine uniform, wet leaf surface, which can promote good growth of orchids, glossy foliage.

Twelve, pests and diseases

To be sterilized (exposure to the hot sun can be), in order to prevent the occurrence of diseases. Orchids in the rainy and high temperature season is most likely to occur white silk disease, available toxaphene 800 times liquid or Bordeaux liquid spray prevention. If the disease is serious, we can use Tobutsu 500-750 times to release it and spray it every 7-10 days. Insect pests to shellfish occur most, this insect attached to the base of the leaf, such as the discovery of shellfish, should be removed in a timely manner. If you want to avoid shellfish infestation, from April, available "1059" 2000 times liquid control.

In order to inhibit the occurrence of orchid diseases, in addition to the usual dryness and humidity of the potting soil should be appropriate control, but also in the selection of pots as much as possible with clay pots, less glazed pots. Especially for poor growth of new orchids dug from the mountains must be planted in clay pots. This makes the potting soil easy to dry, which can promote the growth of orchids and reduce the disease.

Flower is not good Cymbidium

Cymbidium is also known as tiger orchid, Simbi orchid. Evergreen perennial epiphytic herb. It is a general term for large-flowered epiphytic species in the genus Orchidaceae. Pseudobulbs are stout, long elliptic, slightly compressed; they bear 6 to 8 strap-shaped leaves, 70 cm to 110 cm long and 2 cm to 3 cm wide. Flowering stem suberect or slightly curved, 60 cm to 90 cm long, with 6 to 12 or more flowers. Flowers are large, 6 cm to 10 cm in diameter, white, yellow, green, purple-red or with purple-brown markings. It is one of the most widely cultivated orchids and is loved by people all over the world. It is propagated by dividing plants. Prefer warm, moist and semi-shady environment. Use fern roots, moss, bark pieces and other pots. It requires good air permeability and drainage between the roots, and a cool period after the flower buds are formed in the fall before flowering in the spring. The night temperature in winter is about 10°C. Commonly cultivated are: exclusive, yellow cicada orchid, Jaspermum, Tibetan tiger orchid and a large number of hybrids of the best varieties.

Cymbidium orchids are native to the tropical and subtropical plateau of Asia, preferring cool and high humidity environment, with a growing temperature of 10-25℃, and should be placed in a low-temperature greenhouse for care in winter, when the night temperature is around 10℃, the growth is good, and the flower stem is normally elongated, and blooms more in February-March. In the winter temperature is lower than 5 ℃, the leaves are slightly yellow and delayed flowering, flower stem short. But when the overwintering temperature is about 15 ℃, the plant leaves are green and shiny, but the flower stem will suddenly elongate, flowering ahead of January-February, and the flower stem is soft and can not be upright, must be erected to support the pillar.

Propagation and Cultivation

Propagation is usually done by division. Dividing time is mostly in the plant after flowering, before the new shoots have grown, this short period of dormancy. The plant should be properly dried before dividing, and operated when the roots are slightly white and limp. Robust growers are usually divided once every 2-3 years, and each clump of orchid seedlings after division should carry 2-3 pseudobulbs, one of which must be newly formed in the previous year. To avoid wound infection, apply sulfur powder or charcoal powder. Put it in a dry place for 1-2 days and then pot it up separately, that is to say, it will become a new plant. After planting in a semi-shady place, do not water immediately, found too dry can be sprayed to the foliage and a small amount of water on the surface of the pot to prevent the leaves from drying out, fall off and pseudobulbs serious dry shrinkage. Wait until the base of the new shoots grow new roots before watering.

Cymbidium orchids can be potted with 2 parts of fern roots, 1 part of charcoal moss or 1.5-2cm diameter bark pieces as potting substrate, and some crushed bricks, charcoal and other granular materials can be added. It is better to choose tall pots with a diameter of 15-20 centimeters, with 2-4 seedlings in each pot. Cymbidium orchids like high air humidity, spring, summer and fall, in the roots of sufficient water at the same time, should often leaf and water spray. However, in the early spring after the flowering, dahlia orchid's short dormant period, must be less watering, until the new buds grow larger new roots can be more watering.

Dahlia Cymbidium is a large plant with luxuriant growth, which needs more fertilizer than the general orchids, so it should be strengthened with fertilizer during the growing season. Generally speaking, you can mix the fermented cake fertilizer with 1/3 clay, then add water to make a ball about 2cm in diameter and dry it in the sun. In the spring on the surface of the pot, away from the new shoots have a certain distance, the fertilizer can slowly release nutrients for the growth of orchids. It can be applied twice a year, a few grains per pot, or you can apply fermented liquid farmyard fertilizer once every 1-2 weeks, and you can also use a sprayer to spray 1:1:1 nitrogen-phosphorus-potassium composite fertilizer to the leaves and the pot surface, the concentration should be in the range of 3-5%, 1-2 times a week. Stop fertilizing in late autumn.

Cymbidium grandiflorum is more resistant to diseases and pests than general Chinese orchids, but it is still attacked by various diseases to varying degrees in the process of growth, therefore, strengthening the prevention is an important measure to raise good orchids, and it is generally used "Chlorothalonil" or "carbendazim" diluted 1,000 times solution every 10 days. Generally, every 10 days, use "Chlorothalonil" or "carbendazim" diluted 1,000 times to spray both sides of orchid leaves.

Features and Uses

Cymbidium orchids are full-bodied, with bright green leaves and beautiful waxy flowers, which are high-grade winter and spring festival flowers
