Aliases: Ishigaki, Shilan, Hanging Orchids, and Gold Dendrobium
Family Family: Orchidaceae
Scientific name: Dendrobium
Plant species: Perennial deciduous herbs
Origin:
The origin is mainly distributed in tropical and subtropical Asia, Australia and Pacific Islands, and there are about 1000 species in the world. There are about 76 species in China, most of which are located in the southwest, south China, Taiwan and other tropical, subtropical and southern parts of the Qinling Mountains.
Many countries in the world today are widely cultivated, especially in Southeast Asia.
Morphological characteristics:
Stems clustered, erect, slightly reflexed at upper part, slightly scabrous, yellow-green, with flutes. Leaves nearly leathery, short round. Racemes, large flowers, white, apical lavender. Deciduous flowering.
Bulbous stems clustered, cylindrical or slightly flattened, base contracted; leaves papery or leathery, oblong, 2-lobed at top; racemes raceme; flowers large, semi-draped, white, yellow, light rose, or pink And so on, bright and colorful, very beautiful, many kinds of aromatic smell.
It is one of the earliest recorded orchids in ancient Chinese literature. Due to its flower-like shape, graceful appearance, variety of colors, and long flowering period, it is deeply loved and concerned by people of all countries and occupies an important position in the international flower market.
Growth habits:
It is often attached to tree trunks or rocks in 480 to 1700 meters above sea level. Hi warm. Humid and semi-shade environment, not cold. The optimum temperature for growth is 18-30°C, and the growth period is more suitable for 16-21°C. The dormancy period is 16-18°C, and the night temperature is 10-13°C. The temperature difference is kept at 10-15°C. Daytime temperatures exceeding 30°C have little effect on the growth of Dendrobium nobile, and the temperature in winter is not lower than 10°C. Seedlings are susceptible to freezing below 10°C.
Avoid dryness and water accumulation, especially when germination begins and new roots form. However, if it is too humid, it can easily cause rot if it is exposed to low temperatures. When the sky is dry and hot, in addition to watering, spray more water on the ground to maintain a higher air humidity. Evergreen sarcophagus can maintain sufficient moisture in winter, but deciduous sarcophagus can be properly dried to maintain high air humidity.
Wild forest, but the cultivation is still relatively happy light, summer and autumn to shading 50%, winter and spring to shading 30% is appropriate. If the light is too strong, the stem will be enlarged and yellow with yellowish green leaves. However, there is plenty of sunshine, good flowering in autumn, and a large number of flowers.
The soil should use well-drained, breathable crushed fern roots, sphagnum moss, charcoal crumbs, broken tiles, perlite, etc., mainly broken fern roots and sphagnum moss.
Market situation:
Dendrobium had the largest production in Thailand. In 1993, it produced 3,600 tons of Dendrobium annually. In 1994, it exported 62.9 million sticks to Italy, 14.25 million sticks to the Netherlands, and 11.7 million sticks to Germany. It also exported to Japan and North America. In addition, Singapore, Malaysia and Taiwan also have a certain amount of production. The main exporting countries are the Netherlands, Germany, Italy, Britain, France and Japan. The Philippines is mainly self-produced and sold. In Asia, Japan is the largest importer of Dendrobium. In 1993, it sold 2.3 million pots and sold 28 million US dollars, which accounted for the sixth place in sales of potted plants.
China's large-scale production of stone coffins has a short period of time, mainly starting in the early 1990s. Although it started late, it has developed rapidly.
So far, in Guangdong, Kunming, Fujian and other places have a certain scale of production base, in the production of potted and cut flowers can basically meet the needs of the domestic market.
Dendrobium is the largest genus in the orchid family.
The cultivation is divided into temperate deciduous species (Ceramthus spp.) and tropical evergreen species (dendrobium spp.).
The flowers of spring sarcophagus are usually born between the stems and stems, the flowering period is about 20 days, and they are mostly used as ornamental plants. The flower of the autumn sarcophagus is generally born on the top of the stem, and the flowering period is more than one month. It is mainly used for cutting flower viewing. Pseudobulbs are medicinal. Propagation uses ramets and stem segments for cutting or aseptic seeding. Hi warm, moist and half-negative; potted with loose, air-permeable substrates such as fern roots, moss or bark blocks. During the growing season, keep it moist and half-cast, fertilize properly; in winter, it is properly dried and strong sunlight. Winter temperatures above 10°C.
