How to regulate temperature when cultivating Gastrodia elata in plains and low mountain areas
The biggest difficulty in cultivating Gastrodia elata in plains and low mountain areas is controlling high temperatures and regulating temperature differences. (1) For indoor cultivation, cold water can be sprayed in the walkways and space, but water must not accumulate at the bottom layer of the Gastrodia elata. At the same time, open the opposing windows facing north and south for ventilation, or use an electric fan to cool down while opening the windows, so that air convection is achieved and the cooling goal is reached. When the temperature is low, close the doors and windows, and make the temperature difference as small as possible. (2) For outdoor cultivation, more broadleaf trees and green vine plants can be planted on the cultivation site, so that the cultivation site is cool and moist.

Deep plowing is done between the honeysuckle rows and between the plants, which both loosens the soil and cuts off the old surface roots. Topdressing: Honeysuckle should be topdressed once each year after sprouting in early spring and after each flower harvest. In spring
