How to manage Jilin Tianma in winter
The winter in Jilin Province is long and cold, and Gastrodia elata is dormant. Preventing frost injury and decay of Gastrodia elata is the key to harvest Gastrodia elata.
Management of planting Gastrodia elata in ① cellar. Cellar planting Gastrodia elata often overwinters outdoors. Before winter, the soil moisture in Gastrodia elata cellar should be kept at 30%-40% to prevent excessive wetness and stagnant water. It is also necessary to dig drainage ditches around the Tianma cellar to prevent snow water from pouring into the cellar. Before freezing, cover the Gastrodia elata cellar with 15cm thick leaves or weeds, and then cultivate 20cm to 30cm thick cold-proof soil. When cultivating cold soil, keep the soil loose and do not use your feet or shovels. Cold mountain areas, but also with snow defense. Special attention should be paid to prevent frost injury of Gastrodia elata when the temperature is still sunny in early winter and early spring.
Management of Gastrodia elata planted in ② box. Box planting Gastrodia elata is mostly moved into indoor management before late October in autumn, and the humidity of the culture material in the box should be kept at 30%-40%, and the temperature should be kept at 12-18 ℃, so that Armillaria mellea and Gastrodia elata can be combined before overwintering. After 15 days and 20 days, the temperature of Gastrodia elata cultivation room was gradually reduced to 1: 5 ℃, making it spend the dormancy period at a lower temperature. After February and March of the following year, the temperature was gradually raised to 18: 20 ℃ and the humidity was increased to 50%, creating good conditions for the growth of Gastrodia elata and Armillaria mellea.

Teach you Gastrodia elata planted in wooden boxes
Gastrodia elata can be planted in fields, under the shade of trees, indoors, basements, cellar holes, brick ponds and wooden boxes, and high yield can be obtained as long as its growth characteristics are mastered. According to my planting experience last year, I now introduce the cultivation method of asexual Gastrodia elata in a box, which is suitable for beginners because it is easy to control temperature and humidity. In order to grow Gastrodia elata, Armillaria mellea must be cultivated first. After the fungus is cultivated, it is planted with Gastrodia elata. As long as you can buy fresh and high-quality hemp seeds and pure Armillaria mellea are absolutely successful. First, prepare the case: specification 66 x

Does Gastrodia elata in Changbai Mountain of Jilin Province suffer frost damage in the snow year? How to prevent frost damage
The wild Gastrodia elata in Changbai Mountain of Jilin Province is mainly distributed in the alpine broad-leaved mixed forest with cool and humid summer, deep snow in winter, large ground coverage, thick litter layer, shallow frozen layer, 500-2500m above sea level and loose soil. Wild Gastrodia elata has less snow and thick frozen layer in winter, and artificial cultivation of Gastrodia elata has freezing injury at the time of cold prevention measures. The ground was sealed by heavy snow in 1981 and 1982, and the snow was 80 cm thick in winter. The snow was broken and found that the ground permafrost was only 3 cm, so wild Gastrodia elata and home planting
