Planting method of Gastrodia elata
① asexual propagation cultivation method using tubers of Gastrodia elata as reproductive material is called asexual cultivation.
② active fungus material plus new material companion planting method according to the specific conditions of the planting site, the kiln width is 6ml 8cm wider than the length of the fungus material, and the length of the kiln is variable, so it is appropriate to release 20 pieces of fungus material; the depth of the kiln can be adjusted to local conditions, and the kiln bottom is dug up to 10cm, which is shaped into a slope, and then the fungus material can be laid and Gastrodia elata can be planted.
③ sexual reproduction method the planting method of using seeds as reproductive material is called sexual reproduction cultivation. Using white-headed hemp and rice flax produced by seed reproduction as seed flax has strong vitality, not easy to degenerate, and high reproduction coefficient, which is an important way to cultivate Gastrodia elata.

How to adjust the temperature of cultivating Gastrodia elata in plain and low mountain area
The biggest difficulty in cultivating Gastrodia elata in plain and low mountain areas is the control of high temperature and the adjustment of temperature difference. (1) Indoor cultivation can spray cold water in the walkway and space, but can not make the bottom layer of Gastrodia elata stagnant. At the same time, open the north-south opposite window for ventilation, or use an electric fan to cool down, and open the window at the same time to make the air convection and achieve the purpose of cooling. If the temperature is low, close the doors and windows so that the temperature difference is as small as possible. (2) Outdoor cultivation can plant many broad-leaved trees and green vines on the cultivation field to make the cultivation site cool and humid.

Can diammonium phosphate, calcium superphosphate and ammonium nitrate be applied to cultivated Gastrodia elata? How to apply
It can be used. Because these three kinds of chemical fertilizers are all acidic fertilizers, they can increase the acidity of the soil. In terms of properties, it is suitable for the requirements of the growth and development of Armillaria mellea and Gastrodia elata; in terms of composition, these three kinds of fertilizers all contain phosphorus and nitrogen; theoretically, Armillaria mellea needs a certain amount of phosphorus and nitrogen in the process of growth and development. In the process of growth and development, Gastrodia elata can absorb some trace elements and phosphorus with the water in the matrix, so the yield of Gastrodia elata can be increased by applying appropriate amount of acidic chemical fertilizer.
