Brief introduction of Dendrobium
Dendrobium, one of Orchidaceae plants, originally belonged to Phalaenopsis, and now it has become an independent family, which has therapeutic effects on human body, such as eliminating deficiency and heat, benefiting essence and strengthening yin. With the rise of flower industry, people found that it has high ornamental value, so they classified it as Orchidaceae, and gradually moved from a herbaceous garden to a big garden, becoming a very fashionable new flower. Dendrobium plants are composed of fleshy stems, which are as thick as middle fingers, rod-shaped, with leaves like bamboo leaves, and the two sides of stem nodes are opposite. Scapes emerge from the axils of leaves, and each scape has seven or eight flowers, more than 20 of which are racemes, each with 6 petals, spreading in all directions, and the middle lip is slightly rounded. Many varieties have purple valve margin and white valve center, and a few varieties are yellow and orange.

Classification introduction

Chinese name Dendrobium

English name: Dendrobium

Scientific name: 1) Dendrobium nobile (temperate deciduous species): mainly Dendrobium nobile. 2) Dendrobium Autumn (tropical evergreen species): Dendrobium Phalaenopsis is the main species. When pseudobulb matures, it blooms in a warm and short sunshine environment, so it blooms in late summer and early autumn. 3) Other wild species. Dendrobium circinatum

Family name: Orchidaceae, Dendrobium.

Nicknames: Dendrobium Phalaenopsis and Dendrobium

Origin: There are many species, with 1000 species, mainly distributed in China, Japan, Southeast Asia, northern Australia, low-altitude tropical forests in New Guinea and Pacific islands.

Distribution: All parts of Taiwan Province Province are suitable for cultivation.

Uses: cut flowers, potted plants, attached wood cultivation, excellent ornamental plants.

Others: Dendrobium is usually divided into two categories: spring and autumn. As the name implies, Dendrobium flowers in spring and Dendrobium flowers in autumn. In addition, there are many original species of Dendrobium.

There are too many mating varieties of Dendrobium in the market, which is very simple to cultivate and easy to bloom. Generally speaking, Dendrobium is cultivated with snake sawdust and some building rubble, and placed in a sunny place to avoid the midday sun (two hours before and after shading). From spring to autumn, water every day or every other day, and it is cold in winter, about a week or two. If you want to fertilize, you can buy granular fertilizer and put it at 5~ 10, or you can buy liquid fertilizer and spray it at an average concentration of one thousandth per month. Most Dendrobium plants shed their leaves in winter. In principle, orchids planted for two years should be replaced with new media in spring to avoid corruption and acidification of long media. At the same time, changing pots can also promote the vigorous growth of plants and stimulate flowering.

Dendrobium is a member of Orchidaceae, belonging to the largest genus of Orchidaceae, including about 1200 species, mainly distributed in tropical Asia and Pacific islands. There are about 63 species of Dendrobium and 39 species of medicinal Dendrobium in China. Vertical distribution at altitude 100 ~ 3000m.

Dendrobium is an epiphyte with a unique habitat and strict requirements on microclimate environment. Most of them are distributed in clusters on slightly acidic rock cliffs on shady slopes and semi-shady slopes with cool and high humidity. There are trees above for shade, and streams and ditches below for water diversion. They are slightly drought-tolerant in winter and spring, but when they are seriously short of water, all their leaves often fall off, and the bare stems cross the harsh environment and germinate branches and leaves again in the warm season. Often mixed with lichen, moss, bauhinia, fern, Selaginella, Bulbophylla and so on.

Dendrobium adheres to the gravel of the stone wall with its dense fibrous roots, absorbing water and nutrients from the rock layer, while the fibrous roots exposed in the air absorb water from the fog and dew in the air and rely on their own chlorophyll for photosynthesis. Therefore, Dendrobium is strictly limited by moisture in microclimate, especially air humidity, and its distribution area is extremely narrow. Wild Dendrobium is a rare and endangered plant under national second-class protection, and collection and sale are prohibited.
