South China, Shaanxi and Hubei generally grow in mountainous areas with an altitude of 800~2500m, and wild gastrodia elata in Jilin Province is mostly distributed in mountainous areas with an altitude of 500 ~1000 m.
Belt. The vertical distribution of gastrodia elata is related to climatic conditions. The climate in the alpine region is characterized by cold and humid summer and thick snow in winter. Plus there are many trees.
Because of the thick layer of hair and litter and large ground coverage, gastrodia elata is not easy to be threatened by freezing injury. The vertical distribution of gastrodia elata has brought a new trend to artificial cultivation.
To solve the problem, it is necessary to simulate and create the climatic conditions in alpine areas to meet the needs of gastrodia elata growth and development, and artificial cultivation can be successful.

The conditions for planting gastrodia elata are as follows:
1. Gastrodia elata has no roots and leaves, so it can't carry out photosynthesis. It relies on Armillaria mellea to provide nutrition for growth and reproduction. So the first step in planting gastrodia elata is
To cultivate a certain amount of high-quality Armillaria mellea materials, the second step is to introduce gastrodia elata seeds. And planting Armillaria mellea in time. tall gastrodia
Suitable temperature 10-30℃, optimum temperature 20-25℃, air relative humidity about 80%, soil water content 50%-55%, pH value 5-6.
That is, the acidic ecological environment.
2. Select kenaf with a weight greater than 100g and plant it according to the above method. Avoid light when bolting, and carry out artificial pollination when flowering.
Pollination time can be around 10 in sunny days, when the edge of the drug cap is slightly flowered. After pollination, the ear is covered with plastic bags, and when the lower fruit
When a small amount of seeds are sown, they will be harvested from bottom to top as they mature. Due to the short life span of gastrodia elata seeds, the harvested capsules should be sown in time.
3. The flat land can be bordered on the spot, with a width of 80 cm, a depth of 10 cm, and an unlimited length; According to the different slopes, the slopes in the wilderness are built into stepped ridges, ridges and ridges.
At a distance of about 1 m, try to keep trees and weeds at the border, which is convenient for shading and prevents the border from collapsing. Orchard woodland is built according to the terrain, 4
Excavation of drainage ditch.
Precautions:
The main pests that harm the growth of Gastrodia elata are Meretrix meretrix, Toad and Termite. The prevention method is to spread 5% around the border bed when cultivating gastrodia elata?
Patented product-termite control trap is used to trap and kill termites.
