Growing Environment of Wild Dendrobium officinale

Wild Dendrobium candidum is a perennial plant, is a famous traditional Chinese medicine, wild is also a national protected plant. Due to natural reproduction is not easy, excessive mining, lack of resources. So now Dendrobium candidum is cultivated artificially. So now the introduction of wild growth environment, but also in order to create a better cultivation environment.

1. Environment

Mainly grows in the Dabie Mountains in Anhui, the eastern part of Zhejiang, the western part of Fujian, the western part of Guangxi, the fourth Sichuan region and the southeast of Yunnan. It usually grows on trees, on rocks, or in mountains at medium elevations, between transparent forests, on rocks in humid environments. Moist valleys are also suitable for growth. It is very suitable for growing on limestone soil.

2. Temperature

The growth temperature is between 20 and 25 degrees. Higher than 30 degrees affects growth. If you keep 9 to 12 degrees in winter, you can survive the winter safely. Artificial cultivation of minus 2 degrees can survive, more than 41 degrees can not grow, the temperature that can grow is 10 to 35 degrees, the most suitable is between 20 and 32 degrees. High temperatures in summer must be shaded and sprayed to cool down. This is the cultivation in the shed can be adjusted.

3. Moisture

The wild is in a humid, humid environment where the annual rainfall is 1100 to 1500 mm, and the relative humidity is between 60 and 75%. The artificial cultivation environment should be adjusted according to the temperature, and the air humidity is between 60% and 90%. It is generally high temperature and high humidity, low temperature and low humidity. However, it is necessary to prevent the harm of infectious bacteria when it is hot and humid in summer. Affect the quality. Irrigate with neutral water.

4. Soil, light

Generally wild in rocks, cliffs, cliffs, cracks, the root system will not be buried. Artificial cultivation food substrate cultivation, need air permeability, good drainage, fluffy substrate. It should not be too thick to grow. Wild in the light-transparent forest, the transmittance is about 60%, and the artificial cultivation sunshade is between 50% and 70%.

Wild Dendrobium candidum has strict requirements on the environment, and artificial cultivation can only create a similar environment as much as possible. The planting conditions in the shed can be relaxed appropriately.
