How to manage Tianma in winter and spring
After entering November, due to the gradual decline in temperature, Gastrodia elata stopped growing, individual stereotyped, straight into the dormancy period, so low temperature freezing injury should be prevented. In particular, arrow hemp is easy to freeze during the overwintering period, so it is best to use arrow hemp as medicine when harvesting Gastrodia elata in winter, sowing or storing spring seeds in time.
If you do not harvest in winter, you must take cold protection measures before freezing, cover leaves and so on to keep warm and prevent freezing, and remove them next spring to facilitate growth. The temperature should be kept at 1 ℃ and the humidity should be kept at 30%.

What are the requirements for water?
Q: What are the requirements for water? How to manage water properly? A: As a plant, the main component of Gastrodia elata is water, and the weight of water accounts for about 80% of fresh hemp. This is the foundation. However, since Gastrodia elata has no roots, it cannot absorb water from the soil. It can only rely on Armillaria mellea to supply necessary water. This is the main characteristic of Gastrodia elata. The growth of Armillaria mellea also requires corresponding water supply, and it is determined by the symbiotic relationship between the two. They must live together in the same environment.

New technology of electromagnetic promoting growth and high yield of Gastrodia elata
The Gastrodia elata grown in the lightning strike area has high yield and good quality. According to this law, the new technology of improving geomagnetism can produce 25 kilograms of Gastrodia elata per square meter and harvest 80 days ahead of time. The specific operation techniques are introduced as follows: first, planting time and variety selection. The planting of Gastrodia elata is the best in spring, autumn and winter. The provenance should choose the pollination generation without diseases and insect pests, and the degraded second generation inferior species should not be used. Second, choose the place. Adopt the new technology of improving geomagnetism, as long as the magnetic field is suitable, the temperature and humidity are suitable, the mountain area
