Growth environment of Gastrodia elata
Gastrodia elata likes a cool and humid environment, cold-resistant and afraid of high temperature. Gastrodia elata has no roots, no absorption of chlorophyll and production of nutrients, which must be provided by Armillaria mellea. Armillaria mellea is a facultative fungus, often parasitic or saprophytic in the roots and tissues of old trees. It began to grow at 6: 8 ℃, the soil moisture was 60% Mel 80%, and the temperature was 20 ℃. The optimum temperature for growth was 20: 26 ℃, the growth was slow above 28 ℃, and stopped growing above 32 ℃. Gastrodia elata and Armillaria mellea are nutritional symbiosis.

Environmental Conditions for the Growth of Gastrodia elata
First, the effect of temperature on the growth of Gastrodia elata The effect of temperature on the growth of Gastrodia elata: Temperature is the main factor affecting the growth of Gastrodia elata. Gastrodia elata likes to grow in cooler summer and not very cold winter environments. The longer the temperature and time suitable for its growth, the more favorable it is to the growth of Gastrodia elata. (1) The effect of temperature on asexual reproduction of Gastrodia elata L. underground tuber began to grow at about 14℃, grew faster at 20-25℃, and was inhibited at 30℃. The total accumulated temperature of the whole growing season is about 3800℃ in one year. Elevation is 1,000.

How to develop Gastrodia elata production
First, the current market situation. Due to the substantial increase in the cultivation area of Gastrodia elata in the past two years, coupled with the improvement of cultivation techniques, the total output of Gastrodia elata has more than doubled compared with that of three years ago; on the one hand, the output of the production and marketing market of Gastrodia elata has increased significantly, on the other hand, due to the small increase in the processing of pharmaceutical products (proprietary medicines), resulting in the current depressed state of the market. The Gastrodia elata market is similar to other traditional Chinese medicine markets, generally 3-5 years is a "market cycle", so it is not feasible to engage in sexual breeding when the Gastrodia elata market rises.

How to carry out the initial processing of Gastrodia elata
When Gastrodia elata is sold or sold, it should be kept free from collision, beating and mechanical scars after harvest, and then the sediment on the flax body should be gently brushed off with a soft brush and packed into soft-lined wooden cases or plastic boxes. Such as processing dry hemp, it takes a long time, generally there are boiling method and cage steaming method for ripening, and then take the way of drying or drying. In actual production, cage steaming and Kang drying are generally adopted. The operation process is as follows: Gastrodia elata grade → clean water, → high fire steaming → 50 ℃ Kang for 60 minutes, 60 ℃ Kang drying for 60 minutes, 70 ℃ Kang drying for 6.

Artificial cultivation and processing of Gastrodia elata
Gastrodia elata is a kind of herb living by parasitism, and its underground tuber is an important medicinal material, which is widely needed in domestic and foreign markets. In the past, Gastrodia elata was produced by asexual reproduction. Due to less planting and easy degradation of Gastrodia elata, the output and quality can not meet the needs. The use of artificial sexual reproduction can be mass production, and the quality is also good. Although Gastrodia elata is an herb, it has no chlorophyll in the whole body and needs to be parasitized on Armillaria mellea to get nourishment. However, Armillaria mellea is a fungus that also lives at the base of some tree trunks and grows on decomposed initial sap. So,

How to manage Gastrodia elata in autumn
After the beginning of autumn, attention should be paid to heat preservation and humidity reduction in the morning, evening and night, so that the humidity of the culture material is gradually reduced to 40% and 50%. As the temperature drops, Gastrodia elata boxes should be moved into the room in time to keep Gastrodia elata growing for a period of time. When harvesting Gastrodia elata, the humidity should be 30%-35%, so that Gastrodia elata grows well in the box and the yield is high. Gastrodia elata growth period to prevent mold infection. Once there is a green mold, scab and other miscellaneous bacteria infection on the soil layer or box, gently spray a layer of Bordeaux solution (copper sulfate, quicklime, water press 1

What is the prospect of Gastrodia elata?
Q: what are the development prospects of Gastrodia elata? A: this is an issue that most consultants are concerned about. To put it simply, as a valuable traditional Chinese medicine, from collecting wild to artificial cultivation, from a unit yield of only 3 kg to more than 20 kg today, the overall output has increased hundreds of times, but the market is still tight, which explains at least three points: first, Gastrodia elata has entered the ranks of health products from simple medicinal use, while the development and application of health products has a huge market with unlimited potential, and the market for Gastrodia elata tea and Gastrodia elata drinks is hot. It opened up the way of deep processing of Gastrodia elata.

Indoor high-yield cultivation methods of Gastrodia elata bonsai
Gastrodia elata is a valuable traditional Chinese medicine with sweet taste and smooth nature. it has the effect of calming the liver and calming the wind, lowering blood pressure and calming the nerve. it mainly treats dizziness, numbness of limbs, hypertension, epilepsy and other diseases. Wang Jian, secretary of the Party Branch of Da Village, Huangwan Township, Emeishan City, Sichuan Province, successfully used Emei Mountain's rich wild Gastrodia elata and Armillaria mellea to cultivate Gastrodia elata bonsai. First, growth conditions. Gastrodia elata relies on Armillaria mellea to absorb nutrients from wood and rotten leaves for its growth, development and expansion. The stem has no roots, no leaves, and no photosynthesis. In

What tools and equipment are needed for cultivating Armillaria mellea in Gastrodia elata
Bacteria culture is a highly technical and meticulous work, which must have considerable technical level and necessary equipment and tools. The main equipment and tools required are: ① aseptic box: aseptic box, also known as inoculation box, is a small box made of wood and glass, which can be airtight and easy to fumigate with drugs to prevent miscellaneous bacteria infection. The front and rear of the aseptic box is equipped with open and closed glass windows, two holes are opened below, and cloth covers are installed at the opening, and both hands can be extended into the box to operate. The top of the box is equipped with fluorescent lamp or ultraviolet sterilization lamp. ② sterile room: it is the same as

Production technology of Armillaria mellea and germinating bacteria of Gastrodia elata
Artificial cultivation of Gastrodia elata needs two kinds of symbiotic bacteria: germinating bacteria and Armillaria mellea in the process of sexual reproduction. In the production practice, the author found out the culture medium and production technology which can grow both of the two kinds of symbiotic bacteria. The specific practices are as follows. 1. Liquid culture medium: potato (sprouting, peeling, slicing) 100g, hard sawdust, wheat bran, corn flour 50g each, tap water or natural water 1300mL, boiled in a double pot for 30 minutes, then filtered with double gauze. Take filtrate to replenish water to 1000mL
