The growth environment of Dendrobium spp., the growth environment conditions of Dendrobium officinal

Dendrobium prefers cool and moist environments, and often grows on cool and moist tree trunks and rocks.

In particular, it grows best on limestone and trees that are half-shaded and half-yang with bryophytes.

In the southwest region, it is mostly cultivated in the low and middle mountainous areas at an altitude of 300 1000 meters, in the hanging rocks and tree crevices next to the river valleys, with annual precipitation of more than 1000 mm, relative humidity of 80% and 85%, and annual average temperature of more than 17. Hejiang County, Sichuan Province is the main production area of Dendrobium, the average temperature is, the average maximum temperature, the average minimum temperature is, the extreme maximum temperature, the extreme minimum temperature, the annual precipitation is mm, this climatic condition is more suitable for the growth of Dendrobium. The county has a long history of cultivating dendrobium.

Dendrobium officinale is a precious Chinese medicinal material, and the mastery of its growing environment is crucial. Generally speaking, the growth environment of Dendrobium officinale needs to meet the following conditions:1

Climate: Dendrobium officinale prefers a warm, humid and well-ventilated environment, and the most suitable temperature for growth is 20-30. 2.

Light conditions: Dendrobium officinale needs sufficient sunlight, but can not be exposed to the sun, and generally chooses to grow in shade and semi-shade. 3.

Soil requirements: Dendrobium officinale needs nutrient-rich, well-drained soil, as well as a certain pH and permeability to grow. 4.

Water conditions: Dendrobium officinale needs sufficient water, but it should not be too wet, and it is generally necessary to keep the soil clear and moist. Different conditions of the growth environment before the Dendrobium offensis will have different effects on its growth and quality, so it is necessary to reasonably regulate it according to the actual situation in the planting process.

Dendrobium officinale likes to grow in a cool, humid environment, suitable for growth temperature between 15 and 28 degrees, Dendrobium officinale has higher requirements for soil, suitable for growing in loose, breathable, well-drained soil. Dendrobium officinale likes to grow in a half-shade and half-yang environment, and has a high demand for water, so it is necessary to water the plants in time when planting.

Many people don't know what the environmental conditions are for the growth of Dendrobium officinale, which belongs to the orchid family and likes to grow in a cool and humid environment, mostly distributed in Anhui, Zhejiang, Yunnan, Guangxi and other regions. Dendrobium officinale is not cold-tolerant and has high temperature requirements, and the suitable growth temperature is around 15 to 28 degrees.

Dendrobium officinale is suitable for growing in loose, breathable and well-drained soil, and can be mixed with moss, gravel, bark, organic fertilizer and other substrates to prepare soil when planting. Dendrobium officinale likes to grow in a half-shade and half-yang environment, and the breeding environment can be determined according to the change of weather when planting, and it is necessary to do a good job of shading.

Dendrobium officinale has a high demand for water, and the plants should be watered 2 3 times a week during planting in spring and autumn. In summer, the temperature is high, and the plants should be watered once a day when planting; In winter, when the temperature is low, the plants will enter the dormant period, so you don't need to water the plants too much and keep the soil moist and not dry.

In high temperature and humidity weather, Dendrobium officinale is easy to be infected with soft rot and black spot, at this time, the planting should be mentioned to spray pesticides on the plant to prevent and control, if the plant is unfortunately infected with soft rot, you can spray carbendazim solution**; **In the case of black spot disease, you can spray methyl tobuzin solution on the plant**, usually spraying 2 or 3 times.

Where does dendrobium grow.

Dendrobium is suitable for growing on mountain slopes or beside ditches at an altitude of 300-800 meters. Because Dendrobium is a shallow-rooted tree species, it is suitable for growing in loose soil and deep sandy loam soil, and cannot be planted and grown in windy places.

The origin of Dendrobium is Lin'an. At present, Dendrobium is planted in most parts of the country, mainly in the south of the Yangtze River, and only parts of Anhui and Henan are produced in the north.
