Why does Gastrodia elata rot?
This is because Gastrodia elata cultivated in border cellar is covered with 40 cm thick fresh leaves and unripe fallen leaves to protect against cold before freezing. Sawdust and fallen leaves themselves contain a certain amount of water and organic matter, and 40 cm thick fallen leaves accumulate together. In the process of oxidation reaction (fermentation), a large amount of heat is generated, which promotes the heating of Gastrodia elata border cellar, and the temperature can reach 34 ℃. If you do not pay close attention to observation, control the temperature and humidity in time. Even in winter, Gastrodia elata will burn over a long time. In the alpine forest area of Jilin Province, it can be covered with 15 cm thick fallen leaves and 20 cm to 30 cm thick soil before freezing, so that it can be safe and sound.
