How about the cultivation prospects and cultivation techniques of Tianma
In recent years, due to the rebound of the market and price of Gastrodia elata, coupled with the exaggeration or false publicity of some advertisements, the artificial cultivation of Gastrodia elata has been in an uproar, resulting in a doubling of the value of Gastrodia elata.
Gastrodia elata is a perennial herb of Orchidaceae, and its growth and development has specific environmental conditions and material basis. First, Gastrodia elata is a typical heterotrophic type of higher plant, growth and development must take Armillaria mellea as "food". If there is no Armillaria mellea to provide "nutrition", the Gastrodia elata corm will shrink due to hunger and die within 3 years. Therefore, the prerequisite for artificial cultivation of Gastrodia elata is to cultivate the strains and materials of Armillaria mellea. How can we talk about Gastrodia elata without Armillaria mellea? Second, there are more stringent requirements for natural climate and topographic conditions. Wild Gastrodia elata is distributed in the range of 24-45 degrees north latitude and 142 degrees east diameter. The main producing areas of Gastrodia elata in China are Yunnan, Sichuan, Jilin, Guizhou, Shaanxi, Hubei, Xizang, Liaoning, Jiangxi, Anhui, Heilongjiang, Hebei, Taiwan and other provinces and regions. The vertical distribution of wild Gastrodia elata is closely related to the local climatic conditions. for example, wild Gastrodia elata in Hubei and Yunnan provinces are mostly distributed in high mountain areas with elevations of 1300-1900 meters, and Sichuan provinces are mostly distributed at 1200-2500 meters above sea level. Liaoning Province is mostly distributed at 200 UV 400m, and Shaanxi Province is mostly distributed at 800-1000 m. The climate of these areas is characterized by no hot summer, no Greater Cold in winter, rainy summer, moist and cool air. The northern and alpine mountain areas have thicker snow cover in winter, with annual precipitation of more than 1000 mm, air relative humidity of 70% Mel 80%, annual average temperature of 3 Mel 13 ℃, monthly average maximum temperature of 24 Mel 29 ℃, and monthly average minimum temperature of 1.3% Mel 1.6 ℃. The suitable temperature for the growth of Gastrodia elata and Armillaria mellea is 15-25 ℃. If the natural temperature in summer exceeds 30 ℃ in a continuous week, the corm of Gastrodia elata will rot due to high temperature, resulting in reduced yield or no harvest. Therefore, in the south and low-altitude plains and hilly areas, it is not suitable to cultivate Gastrodia elata without modern cooling equipment. even if it is to be planted, it is safe to go to Gastrodia elata producing areas.
The production cycle of Gastrodia elata is long, and it usually takes more than one year from cultivating Armillaria mellea strains and materials to sowing and harvesting. Where conditions are available and the climate is suitable, a large number of Gastrodia elata production can be developed as a project to adjust the agricultural planting structure; on the contrary, this phenomenon of "Gastrodia elata fever" should be treated cautiously, and projects must not be introduced blindly against the laws of nature. leading to a tragedy that makes things worse.

Cultivation seasons and methods of Gastrodia elata
1. The "first culture bed method" of sexual reproduction ①: the new fungus material was cultured with Armillaria mellea from March to April every year, and the seeds were sown with germinating bacteria mixed with Gastrodia elata fruit from May to June. Sexual flax seeds were harvested in November and commercial flax was harvested in November of the following year. This method has the advantages of stable yield, high yield and remarkable economic benefit. ② "two bacteria one mixed planting method": from May to June every year, one time sowing with Armillaria mellea, fungus or branches, Gastrodia elata fruit and germinating bacteria, sexual flax seeds were harvested in November, and commercial flax was harvested in November of the following year. The method has the advantages of simple operation, high yield and efficiency.

Identification method of true and false Gastrodia elata
Gastrodia elata is a valuable traditional Chinese medicine. With the gradual shortage of wild Gastrodia elata resources, Gastrodia elata has been listed as a third-class endangered plant protected by the state. In recent years, although the artificial cultivation of Gastrodia elata has made rapid progress, due to the large demand, market shortage and strong prices, some lawbreakers take the opportunity to enter with the fake as the real one. For this reason, the identification methods of Gastrodia elata are introduced as follows: 1. True Gastrodia elata. There are eight characteristics: ⑴ underground tubers are oval or oval, usually long oval after steaming and drying, slightly flat, and some curved.
