I want to ask more basic information about orchids.

Cymbidium, Cymbidium is divided into big flower strain and small flower strain. The big flower strain is called Cymbidium hybridum, and some are also called Cymbidium hybridum, Tiger Orchid and Cymbidium hybridum. The floret strain is called Guo Lan, including Cymbidium hybridum, Cymbidium hybridum, Cymbidium hybridum, Cymbidium hybridum and so on. Cymbidium hybridum is a hybrid orchid, which can be divided into big flowers, medium flowers and small flowers according to the size of flowers. According to its natural flowering period, it can be divided into early flowering period, middle flowering period, late flowering period and summer and autumn flowering period. The colors of flowers are varied, ranging from crimson to white, from yellow and green to two kinds of compound colors. The scientific name is Cymbidium hybridum, also known as Cymbidium hupehensis, Himbieland Orchidaceae, Orchidaceae and Orchidaceae. Cymbidium hybridum is a world-famous orchid star with long green leaves and magnificent flowers. The plants and flowers of Cymbidium hybridum can be divided into large and medium-sized ones. Flowers are very big, with yellow, white, green, red, pink, multicolor and other colors. They are bright in color, bright in color, neat in pattern and firm in texture. They are luxurious and elegant orchids. There is both the fragrance and elegance of orchids and the richness of orchids. It is very popular in the international flower market and deeply loved by flower lovers. The Japanese call it East Asia Orchid, and the Europeans and Americans call it New Meilan. In a word, orchids are very pleasing. Since Britain cultivated the first hybrid from 65438 to 0889, Europe and America also cultivated a large number of interspecific and interspecific hybrids in the 1940s. Up to now, there are thousands of cultivated varieties of Cymbidium hybridum, which are very popular in domestic and foreign markets and become a unique orchid. The main producing countries of Cymbidium hybridum are Thailand, Singapore, Malaysia and Taiwan Province Province of China. The main selling country is Japan. 1993, Japan consumed 465,438+10,000 pots of Cymbidium hybridum, with sales of1050,000 USD. In Europe, it is mainly produced in the Netherlands, with sales of $80 million. Therefore, Cymbidium hybridum still occupies a certain share in the international flower market, and its position is no less than other tropical orchids. Morphological characteristics Cymbidium hybridum is a perennial epiphytic herb. Pseudobulb oval, stout, rectangular, slightly flat; There are 6-8 strip-shaped leaves on it, which are 70cm- 1 10cm long and 2cm-3cm wide, drooping, light green and shiny. The flower stems are nearly erect or slightly curved, with a length of 60 cm -90 cm and 6 flowers-12 or more. The flowers are large, with a diameter of 6 cm- 10 cm, and the colors are white, yellow, green, purplish red or with purple-brown stripes, with a slight aroma. Personal experience: Cymbidium hybridum is in an environment with good air circulation and cool temperature; Flowers can bloom for a month at most, which is one of the reasons why many people like planting. Common cultivated varieties are magenta Annabel and Heathery, blood blue Barcelona, King of the Forest, LevisDuke and Vanguard, red Carmen and RedBeauty, milky white Cascade and Madrigal, yellow GoldenFleece and Troubadour, silver gray Molly and white bride TheBride. Biological characteristics of Cymbidium hybridum native to southwest China. It is usually wild in the shade of streams, ditches and forests. I like warm winters and cool summers. The optimum growth temperature is 10-25℃. The temperature at night is about 10℃. The leaves are green, the flower buds grow and develop normally, the flower stems elongate normally, and they bloom in February-March. If the temperature is lower than 5℃, the leaves will turn yellow, the flower buds will not grow, the flowering period will be postponed to April-May, and the flower stems will not elongate, which will affect the flowering quality. If the temperature is around 15℃, the flower buds will suddenly elongate and bloom in1-February, and the flower stems will become soft and unable to stand upright. If the temperature is as high as: 20℃ at night, the leaves will flourish, which will affect flowering and the buds will turn yellow. In a word, the bud formation, stem drawing and flowering of Cymbidium hybridum need a large temperature difference between day and night. Cymbidium hybridum has high requirements on water quality, likes slightly acidic water and is sensitive to calcium and magnesium ions in water. Rainwater irrigation is the most ideal. Higher air humidity is needed in the growing period. For example, the humidity is too low, the plants grow badly, the roots grow slowly and thin, the leaves become thick and narrow, and the leaves turn yellow. Generally speaking, Cymbidium hybridum is afraid of dry and wet. Light is an important factor affecting the growth and flowering of Cymbidium hybridum. Cymbidium hybridum is a light-loving plant in Orchidaceae, and sufficient light is beneficial to leaf production, flower stem formation and flowering. Too much shade, slender leaves, unable to stand upright, small pseudobulb, easy to get sick, affecting flowering. Shading in midsummer is 50%-60%, and sunshine in autumn is beneficial to the formation and differentiation of flower buds. In the rainy and snowy days in winter, if auxiliary light is added, it is extremely beneficial to flowering. The scientific name of Cymbidium hybridum belongs to Orchidaceae. Cymbidium hybridum, also known as Cymbidium hybridum, Xia Lan, Cymbidium hybridum, Cymbidium hybridum and Cymbidium polycarpum, is often 6-12, and it is full of fragrance. Traditional famous varieties include Shanghai Mei, Xie Peimei and Jin. It is one of the longest cultivated and most popular orchids in China, and was often called "Hui" in ancient times. Its plants are graceful and graceful, the orchid leaves are both rigid and flexible, the posture is graceful, and the fragrance is beautiful, which has attracted thousands of orchid lovers in Qian Qian. Morphological characteristics: pseudobulb of Cymbidium hybridum is not obvious, with thick and long roots, 5-7(9) leaves, 20- 120cm long and 0.6- 1.4cm wide. Strongly erect, usually pleated at the bottom, V-shaped in cross section, with thick serrated edges. The flower stems are erect, 30-80 cm high, with 6- 12 flowers; The color is mostly light yellow-green, with fragrance, slightly inferior to Chunlan. The flower is 5-6 cm in diameter, the petals are slightly smaller than the sepals, the lip has no obvious three leaves, the middle lobe is oval, and there are many crystal clear mastoid hairs on it, with the top rolled back and short hairs on the edge; Lips are white with purple spots. The flowering period is from March to May. The distribution area is similar to Chunlan; South of Qinling Mountain, north of Nanling Mountain and southwest of China are one of the orchids with strong cold tolerance. Origin abounds in Hubei, Hunan, Guizhou, Yunnan, Shaanxi and Sichuan. Orchids grow on sunny slopes of high mountains, with abundant sunshine and good ventilation conditions. As the ancients said, "Orchids give birth to yin, and benefits give birth to yang", so families should pay attention to solving the lighting problem and set up a similar ecological environment for orchids. Put the orchid pot in the southeast and sunny position, so that you can enjoy plenty of sunshine all year round. Except in summer and early autumn, sun-shading nets should be used to block sunlight around noon, and direct sunlight can be used in other seasons to enhance photosynthesis, accelerate the manufacture of nutrients and promote plant growth. Cymbidium hybridum is traditionally divided into red shell, green shell, red-green shell and white-green shell according to the color of flower stems and flower sheaths. Like Chunlan in flower shape, it is divided into lotus petals, plum petals and narcissus petals. There is no other color on the flower, and the same color is also called "Su Xin". An Interpretation of the History and Culture of China Whelan's "Hui" appeared in Qu Yuan, a great poet of Chu State in the Warring States Period. In his words, he said, "There are nine acres (one acre and twelve acres-the leader) and a hundred acres of trees." The "Hui" mentioned here can only be understood as a kind of vanilla with good fragrance, and whether it refers to the orchid we are talking about today is still controversial. What can be identified as the "Hui" of cymbidium today is the Hui in Youfangge written by Huang Tingjian, a poet and calligrapher in the Song Dynasty, which reads "Cymbidium is full of flowers and fragrance, but it is not enough for those who are full of flowers and fragrance". Cymbidium hybridum and Cymbidium hybridum were very popular in Song Dynasty, so it is necessary to distinguish these herbs. These two words of Huang Tingjian became the basis for future generations to distinguish cymbidium from cymbidium. Modern plant taxonomy named this cymbidium that blooms in late spring as cymbidium. If Huang Tingjian only distinguishes orchids from Hui by their characters, then Kerou Zhu's Notes on Incense in the Early Qing Dynasty noticed the different cultivation methods of orchids and Hui. He said: "if you like the sun, you must bask in the sun at three o'clock in the first half of the day ... when you are in Lanzhou, you will be able to make a pilgrimage." During the years of Qianlong, Jiaqing and Daoguang in Qing Dynasty, there were many famous products in Huilan, such as Dayipin, Mei Cheng, Guanding, Shanghai Mei, Pan Lvmei and Laizi. Some famous orchid products have been recorded in Xu Naihe's Orchid Concentric Record during Tongzhi period in Qing Dynasty. For example, the first of the eight famous orchids is called the top grade in Whelan Tong Xinlu, which is praised by a poem: "The scholar is arrogant and praises the leader; Since entering Jiangnan, it is not easy for a thousand dollars to win this award. " The early Qing students' analysis and interpretation of the petal shape of orchids in Miscellanies of Yi Lan opened the door to orchid aesthetics. It was not until the reform and opening-up era that a large number of irises and exotic flowers and herbs appeared. In the past two hundred years, the flower aesthetics of Cymbidium paid special attention to the petal shape and had a wide influence, which became the traditional aesthetic concept of Cymbidium. In 12 (1923), Wu Enyuan, a native of Yuhang, compiled A Brief History of Orchids, which further summarized the traditional varieties and new species of Orchids at that time and divided them into three categories: red-shelled orchids, green-shelled orchids and red-green orchids. From 65438 to 0959, Yao's book Orchid in Yilan, Hangzhou added iris and plain flower. After 1980s, a large number of new varieties of orchids were developed, and orchid families around the world added exotic flowers and colorful flowers to orchids according to the new discoveries. At this point, Cymbidium hybridum has become a huge and distinctive branch of orchids in China. Orchids had spread to Japan and South Korea in the Qing Dynasty and the Republic of China, especially in the 1930s and 1940s, the Japanese collected a large number of orchids from China and sold them to Japan for cultivation. However, due to years of war in China, there were two or three man-made disasters in the decades after the founding of the People's Republic of China. By the end of last century, there was an orchid craze in Guoxing, Wang Lan and China, and some traditional orchids could not be found in China, so they had to be sold back to China from Japan. The development history of an orchid also reflects the rise and fall of a nation. Huang Tingjian, a great poet and calligrapher of Huilan in China, said in Youfangge that "Orchid is like a gentleman" and "You have a scholar-bureaucrat", which opened the way for Huilan to appreciate. Li Yu, a writer and florist in the early Qing Dynasty, specially wrote an article about "orchids", saying: "The reason why orchids are inferior is not the flowers and fragrance, but the leaves ... the leaves are bitter and long ... and they are too fat." Generally speaking, if cultivated well, the plants of Cymbidium hybridum are taller than Cymbidium hybridum, and the flower branches are also large and tall, with many flowers, which are very magnificent and bright, and the fragrance is overflowing. Therefore, people who appreciate doorways will appreciate Cymbidium hybridum and Cymbidium hybridum, while people who watch the scene of bustle will appreciate Cymbidium hybridum more than others. In recent years, the price increase of Cymbidium hybridum is often higher than Cymbidium hybridum, and more than that. This is a general reward for cymbidium. 2008-02-0416: 31:21supplement: I hope I can help you. I planted it myself.

This year, it will bloom in the Lunar New Year.

Orchids are distributed in subtropical and tropical Asia (such as northern India, China, Japanese, Malaysian, Philippine and Borneo) and northern Australia, and usually grow in high altitude areas with cool climate. Temperate orchids are mostly native orchids. They are commonly known as national orchids in Chinese-speaking circles in China, Chinese mainland, Hongkong, Macau, Taiwan Province and Singapore, and have been cultivated and appreciated for thousands of years in ancient China. Most of the tropical orchids are epiphytic orchids, which are large in size and generally called orchids or cymbidium. Classification: Plant phylum: Angiosperm phylum: Monocotyledon phylum: Asparagaceae or Orchidaceae: Orchidaceae: Orchid: Orchid: Orchid: 52 species.
