In Asia, Japan is the largest importer of Dendrobium, with the market sales of 1993 of 2.3 million pots and the sales of $28 million, accounting for the sixth place in the sales of potted flowers. The time for mass production of Dendrobium in China is short, mainly from the early 1990s. Although it started late, it developed rapidly. Up to now, there are some production bases in Guangdong, Kunming, Fujian and other places, and the production of potted flowers and cut flowers can basically meet the domestic market demand. Dendrobium is the largest genus in Orchidaceae, and its origin is mainly distributed in tropical and subtropical Asia, Australia and Pacific islands, with about 1000 species in the world. There are about 76 species in China, most of which are distributed in tropical, subtropical and south Qinling areas such as Southwest China, South China and Taiwan Province Province. It grows at an altitude of100-3000m, and often adheres to trees or rocks. This genus is epiphytic orchid, and its morphological characteristics are very different. Pseudobulb is tufted, cylindrical or slightly flat, and its base contracts; Leaves papery or leathery, oblong, 2-lobed at the top; Racemes; Flowers are large, semi-pendulous, white, yellow, light rose, or pink. They are gorgeous and beautiful and many kinds smell good. Dendrobium is an epiphytic orchid with compound stems, with nearly a thousand original species. It is one of the major genera of Orchidaceae, and its origin is widely distributed, from Japan and Taiwan Province Province in Asia to Thailand, Indonesia and Malaysia, and then to Australia and New Zealand. Dendrobium nobile in Japan and Dendrobium nobile in Thailand, Singapore and Hawaii are the most famous. Especially when it comes to Thailand, people think of Dendrobium nobile. Dendrobium can be divided into two kinds. One is Dendrobium nobile, which blooms in spring and the pedicels are pulled out at the stems on both sides. The other is Dendrobium nobile, which blooms in autumn, and the pedicel is pulled out from the top of the stem, and each pedicel can bear one or twenty flowers. The flower shape is blue (Phalaenopsis series), and the small flowers are divided into temperate deciduous species (Dendrobium nobile) and tropical evergreen species (Dendrobium nobile) in cultivation. The flowers of Dendrobium nobile are usually born in the internodes of stems, and the flowering period is about 20 days. Most of them are ornamental as potted plants. The flowers of Dendrobium nobile are usually planted at the top of the stem, and the flowering period is more than one month, which is mainly used for cutting flowers for viewing. Pseudobulb can be used as medicine. Propagation by ramets, stem cutting or aseptic sowing. Like warm, humid and semi-cloudy; The flowerpot adopts loose and breathable substrate, such as fern root, moss or bark block. Keep moist and semi-cloudy during the growth period, and apply fertilizer appropriately; Proper dryness and strong sunshine in winter. The overwintering temperature is above 65438 00℃. Dendrobium species include Dendrobium nobile, Dendrobium densiflora, Dendrobium drumstick and Dendrobium butterfly. There are 1500 species in the world. Except for a few species, all belong to epiphytic orchids. Before 1980, only 57 species of Dendrobium were found in China. Later, Dendrobium 19 species were discovered and named, which enriched the germplasm resource bank of Dendrobium in China, and now there are 76 species [1]. The species of Dendrobium in China only account for about 5% of the world's total, but historically, its medicinal development and utilization are in the forefront of the world, and it is an important commonly used Chinese herbal medicine.

Rinderle. ), but in fact, there are many kinds of folk medicines, and there are also many varieties used to extract certain ingredients as raw materials for medicines. Among 76 species of Dendrobium in China, nearly 40 species are medicinal plants [2]. Some medicinal Dendrobium species have been exported for a long time and are very famous in Southeast Asia and some areas in Europe and America. Globally, Dendrobium is mainly distributed in tropical and subtropical areas between north latitude15 31'and south latitude 2512'. But in China, it is mainly distributed in the south of 30 north latitude, 30 north latitude? There is also a small distribution between 35. There are 76 species of Dendrobium in China? . ?

Compared with Dendrobium nobile, Dendrobium nobile, Dendrobium nobile and Dendrobium nobile in Sichuan, Dendrobium nobile is a famous family, and its price is dozens or even hundreds of times higher. Therefore, driven by the interests, all kinds of Dendrobium candidum semi-finished products produced by ordinary people's workshops in Wenzhou and Jinhua, although only a few of them are Dendrobium candidum, have become Dendrobium candidum products after being produced and packaged by some health care products manufacturers and put on the counter of shopping malls, and even marked with thousands of dollars.
