Introduction to the method of high bud propagation of Wandai orchid

There are many varieties of Wandai orchid, and it is an important family of gas orchid. The difficulty of artificial cultivation of Wandai orchid is not high, and the vitality of Wandailan is very tenacious, so it is not difficult to breed. Artificial propagation of Wandai orchid can use the method of high bud propagation, the editor will give you a brief introduction.

Wan Dailan

Wandai orchid can propagate with high buds. At the end of autumn, high buds grow in the axils of leaves, when the tall buds grow to 5-7. At 5cm, use a sharp and sterilized knife to cut off the tall buds from the mother plant and plant them in a basin filled with snake sawdust, which can be transplanted to a larger basin. Remember to apply medicine on the incision to avoid being infected by germs. In addition, when the plants cultivated for many years grow to more than 1 meter, the terminal buds about 30 to 46 centimeters long can be cut off, and the incisions on both sides can be sterilized, and then planted in the basin to keep them moist.

Propagation methods of Wandai orchid Disease and insect control of Wandai orchid

Wandailan is a general term for orchids of the genus Orchidaceae. There are about 50 primitive species, and the hybrid varieties are very rich, originating from India, Malaysia, the Philippines and other places. Chinese experts translated it as "Wandai" which probably means that it has strong vitality and can be passed on forever from generation to generation. The ornamental value is very high and can be watched throughout the year. Let's take a look at the breeding methods of Wandai Orchid.

The growth habit of Wandai orchid

Wandailan is afraid of cold and heat, waterlogging and drought. The temperature as high as 35 ℃ in summer has little effect on its growth, and it does not need to use a lot of plant materials in cultivation. Many flower farms in Thailand are very extensive in planting Wandailan. They often use wooden strips to nail into small square frames in which a few pieces of charcoal, broken bricks or coconut clothes can continue to grow. Some even hang up its plants with only a nylon rope and hang them under an orchid shed or tree, like a "duck". It can also grow leaves and blossom when sprinkled with water and fertilizer.

Propagation methods of Wandai orchid

Wandai orchids can be propagated with high buds. At the end of autumn, tall buds grow in the axils of leaves. When the tall buds grow to 5cm and 7.5cm, use a sharp and sterilized knife to cut off the tall buds from the mother plant and plant them in a basin filled with snake sawdust, which can be transplanted to a larger basin. Remember to apply medicine on the incision to avoid being infected by germs. In addition, when the plants cultivated for many years grow to more than 1 meter, the terminal buds about 30 to 46 centimeters long can be cut off, and the incisions on both sides can be sterilized, and then planted in the basin to keep them moist.

Disease and pest control of Wandailan

1. Phytophthora

The disease occurs all the year round, but in the rainy season, the disease is the most serious when the water is too wet or poorly ventilated, especially the seedlings just out of the bottle are the most vulnerable. The infected site produced brown disease spot, which expanded rapidly in high temperature and humidity, and finally showed black brown spot, and deciduous stem rot until the plant died.

[prevention and treatment] ① avoids excessive dampness, improves ventilation conditions and has sufficient light. ② avoids partial use of nitrogen fertilizer and reduces plant overgrowth and weakness. ③ was sprayed with 1x800 carbendazim or 1x1000 Haoshengling liquid. The cut cut of ④ diseased plant was smeared with large cornflour and placed in a dry place without watering for a week, which could stop the spread of the disease.

2. Anthrax

[symptoms] too dense planting, poor ventilation, moisture imbalance or injured wounds are susceptible to diseases. At the initial stage of the disease, the leaves produce brown sunken spots, which later expand into round or irregular spots, and in severe cases, there is gangrene in the center of the spot.

[prevention and treatment] ① planting should not be too dense, increase light, drainage and ventilation should be good. ② culture of strong seedlings, do not often move plants, so as not to cause damage and disease. ③ cut off the diseased leaves and smeared the wound with 500x Dasheng-45 solution and 800x Vibrio. ④ was sprayed with 1 000 times thiophanate methyl or carbendazim once a week.

3. Soft rot

The disease is easy to occur when excessive application of nitrogen fertilizer is due to high temperature and humidity and poor ventilation in spring and summer. At the initial stage, the waterlogged disease spots were produced by bacteria invading the leaves or heart leaves, which expanded rapidly and contained more water, but in the later stage, the diseased leaves became yellow and fell off, and the whole plant died of soft rot. The disease spreads rapidly and must be prevented and treated as soon as possible.

[prevention] ① improves growth conditions, increases ventilation, and reduces temperature and humidity. The spread of the disease can be prevented by removing the susceptible part of ② and smearing it with antibiotic powder without watering for a week. ③ was sprayed with streptomycin 1000 times aqueous solution, stone sulfur mixture or Bordeaux solution once a week.

4. Leaf blight

[disease] the tip of the leaf produces small black spots, which gradually expand into irregular spots, the periphery of the spot is dark brown, the middle is grayish brown, and in severe cases, it spreads the whole leaf, and finally withered and fallen leaves.

[prevention and treatment] the diseased leaves were removed by ① and sprayed with 500x Dasheng-45 or 1000 times Haosheng. For ②-susceptible plants, Rain Water or stop watering should be avoided to prevent the disease from getting worse. ③ spray 500x Dasheng-45 regularly once a day as a precaution.

5. White silk disease

Wandailan was more prone to this disease. At the initial stage, the base of the pseudocorm blackened and rotted, gradually produced white hyphae on the disease spot, and the diseased plants gradually withered and died.

[prevention and treatment] the pseudocorm with disease spot was removed by ①, together with the planted pot and plant material, it was burned by fire. ② was sprayed with 500 times Dasheng-45 liquid or 1000 times carbendazim solution once a week.

Introduction of Vanda: how to raise orchids / how to breed orchids Vanda the introduction of orchids is a general name for orchids of the genus Vanda, the scientific name Vanda (formerly Sanskrit in India, meaning orchids hanging on trees), is a strong member of the orchid family. In Chinese, it is transliterated as "ten thousand generations". It belongs to the genus Orchidaceae. There are about 50 primitive species in the genus. The hybrid variety is very rich, and it is one of the most important flowers. This genus is mostly epiphytic, with some lithophytic or geophytic orchids distributed in India, the Himalayas, Southeast Asia, Indonesia, the Philippines, New Guinea, southern China and northern Australia. In 1981, Singapore selected Zhuo Jin Wandai Orchid as the national flower. Dai Lan is a strong member of the Yanglan family. Its scientific name VANDA was originally the Sanskrit language of India, meaning orchids hanging from trees. Some people think that the word actually means "orchid" in India. In any case, it can be inferred from this generic name that Wandailan was first discovered in India. There are about 60mur80 species of Cymbidium, which are widely distributed in China, India, Malaysia, Philippines, Hawaii, New Guinea and Australia. Chinese experts translated it as "ten thousand generations", probably because it has strong vitality and can be passed on forever from generation to generation. Wandailan is a large category of tropical orchids. Singaporeans are particularly familiar with this orchid. The famous Wandai orchid variety Zhuo Jin Wandai orchid is the national flower of this beautiful tropical country. The morphological characteristics of Wandai orchid its plant is upright, there is no pseudobulb, and the leaves grow on both sides of the single stem, just like a pair of ribs in the front chest of the human body. Some varieties with long stems can also be branched or climbing. The leaf is banded, the meat is hard, and the midrib is concave like a groove, showing a "V" shape, which can withstand strong light and drought and is not easy to wither. Its aerial roots are thick and long, some like chopsticks, pulled out from the leaves on the stem, all the strong plants, its white roots are many, like Santa Claus's beard, hanging down one by one. The more white roots there are, the more prosperous the flower will be. Wandailan in Thailand and Singapore can pull out a pedicel and blossom in almost every leaf axil, and each plant can blossom 15-20 branches. On the other hand, Wandailan produced in Japan can only have 3 or 4 flowers, which may be closely related to the weather. The flowering season of Wandailan is quite spectacular, with round, long and triangular petals. The labellum is healed with the style, and the lateral and middle pieces express each other. The flower shape is sturdy, the flower posture is unrestrained, and the flower color is gorgeous. In addition to having a variety of monocolors, there are also two colors full of spots or reticulation. The ecological habits of Wandailan are native to Malaysia and Florida and the Hawaiian Islands in the United States. So far, 70 native species have been found, and more than 1,000 hybrids have been artificially bred, which is an important family of aerial orchids. Two native species have been found in Hainan Island, China, one is the pure color orchid, the other is the dense leaf orchid, which are mostly attached to the trees in the primeval forest. Wandai orchid cultivation techniques 1, lighting: the above general varieties of Wandai orchid, need strong light, need to use 40-50% shading net in the local high temperature season, and even do not need shading in winter. 2. Temperature: Wandai orchids cultivated in Xishuangbanna prefer high temperature environment. The most suitable temperature is 20 ℃ and 30 min. Because there is no frost all year round, Wandai orchids can blossom normally in any season. 3. Water dampness: the above two varieties of Wandailan are typical tropical aerial plants, and adequate moisture and air humidity must be ensured in daily management. The exuberant growth can be maintained by natural conditions in the rainy season. In the dry season, the air humidity must be kept at about 80% by artificial sprinkling. 4. Fertilization: Wandailan needs more fertilizer than other orchids, so during the period of vigorous growth, diluted fertilizer can be applied once every 7 to 10 days. The best fertilizer is the ratio of nitrogen, phosphorus and potassium at 10:10:5. 5. Potted soil: because the root of Wandailan belongs to aerial root, any medium with good drainage can be applied, such as snake sawdust, broken bricks, charcoal, coarse gravel sand, etc., whether used alone or mixed, it is a good potted soil. In addition to the medium, the pots must also be very fastidious. In pots of various materials, wooden striped pots and pottery pots are the best, and a few more holes are pierced in the pots, which are more conducive to good drainage and air circulation. Wandailan can also grow well on snake boards or tree trunks. No matter how it is cultivated, keep in mind that the basin soil must be well drained and well ventilated. 6. Change the basin: Wandailan should not change the basin frequently. Unless disturbed by diseases and insect pests, the basin can be changed at least once every 3 years. The Wandai orchid in spring is about to enter the vigorous growth period, which is a good time to change the basin. Wandai orchid, which has been growing for many years, its root system will be tightly attached to the inner wall of the pot, so if it is planted in a pottery basin, it is best to break the basin and change the pot, so as not to damage the root system when taking out the plant. 7. Reproduction: Wandailan can reproduce with high buds. At the end of autumn, Wandailan grows tall buds in the axils of leaves. When the tall buds grow to 5cm and 7.5 cm, use a sharp and sterilized knife to cut off the tall buds from the mother plant and plant them in a basin filled with snake sawdust, which can be transplanted to a larger basin. Remember to apply medicine on the incision to avoid being infected by germs. In addition, when the plants cultivated for many years grow to more than 1 meter, the terminal buds about 30 to 46 centimeters long can be cut off, and the incisions on both sides can be sterilized, and then planted in the basin to keep them moist. 8. pest control: tough leaves are the main reason why orchids are not easy to suffer from diseases and insect pests. with the exception of snails and slugs, common pests are rarely found on strong orchid plants. However, when the water is retained in the leaves for too long, or infected by the virus, some dark markings or patches often appear, and gradually rot. If the condition is mild, the affected area can be removed, and if the rot is too wide, the whole orchid must be discarded so as not to infect other orchid plants. Disease control of Phytophthora blight: it occurs all the year round, but in the plum rain season, the disease is the most serious when watering is too wet or poor ventilation, especially the seedlings just out of the bottle are the most vulnerable. The infected site produced brown disease spot, which expanded rapidly in high temperature and humidity, and finally showed black brown spot, and deciduous stem rot until the plant died. Prevention and treatment methods: (1) avoid excessive humidity, improve ventilation conditions, (2) avoid partial use of nitrogen fertilizer, reduce plant overgrowth and weakness (3) spray more than 800 bacteriophage or 1000 Haoshengling solution (4) smear the wounds resected by diseased plants with large cornmeal, and then place them in a dry place without watering for a week, which can curb the spread of the disease. Anthrax: susceptible to diseases such as dense planting, poor ventilation, moisture imbalance or injured wounds. At the initial stage of the disease, the leaves produce brown sunken spots, which later expand into round or irregular spots, and in severe cases, there is gangrene in the center of the spot. Prevention and control methods: (1) planting is not too dense. Increase the light; drainage, ventilation should be good (2) cultivate strong seedlings, do not often move plants, so as not to cause damage and disease (3) cut off the diseased leaves, and smear the wound with 1x500 times Dasheng-45 water solution, 1pm 800 times carbendazim solution (4) spray 1 up to 1000 times methyl topiramate or carbendazim water solution soft rot disease once a week: high temperature and humidity in spring and summer, poor ventilation, excessive application of nitrogen fertilizer is more prone to this disease. At the initial stage, the waterlogged disease spots were produced by bacteria invading the leaves or heart leaves, which expanded rapidly and contained more water, but in the later stage, the diseased leaves became yellow and fell off, and the whole plant died of soft rot. The disease spreads rapidly and must be prevented and treated as soon as possible. Prevention and treatment methods: (1) improve growth conditions, increase ventilation, reduce temperature and humidity (2) remove susceptible parts, smear with antibiotic powder and do not water for a week, can stop the spread of the disease (3) use streptomycin 1000 times water solution. Stone sulfur mixture or Bordeaux solution, spraying leaf blight once a week: the leaf tip produces small black spots, gradually expands into irregular spots, and the periphery of the spot forms dark brown. The middle is grayish brown, and in severe cases, it spreads throughout the leaves, and finally withered and fallen leaves. Control methods: (1) remove diseased leaves, spray 500x Dasheng-45 or 1000 times Haoshengling (2) susceptible plants, avoid Rain Water or suspend watering, and prevent aggravation of the disease (3) regularly spray 500x Dasheng-45 once a day to prevent white silk disease: Cymbidium is more prone to this disease, at the initial stage, the base of the pseudo-corm blackened and rotted, gradually produced white hyphae on the spot, and the diseased plants gradually withered and died. Prevention and treatment methods: (1) remove the pseudocorm with disease spot, together with the planted pot and plant material to burn with fire (2) spray 500x Dasheng-45 liquid or 1000 times carbendazim water solution once a week. Cultural background of Wandailan in India, Malaysia, Philippines, South China and Northern Australia in 1981, Singapore selected Zhuo Jin Wandai Orchid as the national flower.

It symbolizes the hard-working and brave fighting spirit of the nation. Wandai orchid has a wide variety of colors, from yellow, red, purple to blue, its calyx is well developed, especially the two lateral calyx is larger, is the most eye-catching part of the whole flower, but its petals are smaller and lip petals are smaller. The flower patterns of Wandailan are also various, some reverse and twisted, some round and flat, its florescence is very long, often a flower can bloom continuously for several weeks, and as long as the conditions are right, it can probably bloom annually, and many kinds of flowers still have fragrance. In inflorescence, there are at least a dozen flowers of Wandailan, blooming sequentially from the bottom up. In addition to flowers, the leaves and roots of Wandailan are very distinctive. The leaves are rod-shaped, fleshy and succulent, growing on both sides of erect stems, and beautiful inflorescences grow from leaf axils; another kind of leaves are belt-shaped. Wandailan is a typical epiphytic orchid whose thick cylindrical aerial roots grow continuously from the stem and must be in direct contact with the air. Compared with other orchids, Wandai orchids should prefer light. After the plant is mature, if the light is enough, it can blossom 2mi 3 times a year. At the same time, Wandai orchid has strong drought resistance and extensive nature, so it is a kind of orchid which is easy to be cultivated in tropical areas. Since the middle of last century, Wandailan has become popular all over the world. As long as it is warmer, you can see them. Orchid lovers all over the world have also cultivated a large number of Wandai orchid varieties, in addition to the interspecific hybrids within the genus, there are many intergeneric hybrids with other orchids. Wandailan is afraid of cold, not of heat, of waterlogging, not of drought. In summer, the temperature as high as 35 ℃ has little effect on its growth. And there is no need to use a lot of plant materials in cultivation. Many flower farms in Thailand are very extensive in planting Wandailan. They often use wooden strips to nail into small square frames in which a few pieces of charcoal, broken bricks or coconut clothes can continue to grow. Some even hang up its plants with only a nylon rope and hang them under an orchid shed or tree, like a "duck". It can also grow leaves and blossom when sprinkled with water and fertilizer. The characteristic of this kind of Ruo with Xin and continuous self-improvement is incomparable to many pampered famous flowers. Wan Dailan pictures
