What are the requirements for water?
Q: What are the requirements for water? How to manage water properly? A: As a plant, the main component of Gastrodia elata is water, and the weight of water accounts for about 80% of fresh hemp. This is the foundation. However, since Gastrodia elata has no roots, it cannot absorb water from the soil. It can only rely on Armillaria mellea to supply necessary water. This is the main characteristic of Gastrodia elata. The growth of Armillaria mellea also requires corresponding water supply, and it is determined by the symbiotic relationship between the two. They must live together in the same environment.

How to manage Tianma in winter and spring
After entering November, due to the gradual drop in temperature, the new gastrodia elata stops growing, individual stereotypes, straight into the dormancy period, so we should prevent low temperature freezing injury. Especially arrow hemp is easy to freeze during winter, it is best to use arrow hemp as medicine when collecting gastrodia elata in winter, sow rice hemp and white hemp in time or store spring seeds. If it is not harvested in winter, cold protection measures must be taken before freezing, covered with leaves, etc. to keep warm and freeze, and removed in the spring of next year to facilitate growth. The temperature should be kept at 1-5℃, and the humidity should be kept at 30%.

New technology of electromagnetic promoting growth and high yield of Gastrodia elata
The Gastrodia elata grown in the lightning strike area has high yield and good quality. According to this law, the new technology of improving geomagnetism can produce 25 kilograms of Gastrodia elata per square meter and harvest 80 days ahead of time. The specific operation techniques are introduced as follows: first, planting time and variety selection. The planting of Gastrodia elata is the best in spring, autumn and winter. The provenance should choose the pollination generation without diseases and insect pests, and the degraded second generation inferior species should not be used. Second, choose the place. Adopt the new technology of improving geomagnetism, as long as the magnetic field is suitable, the temperature and humidity are suitable, the mountain area

Authentic cultivation techniques of Gastrodia elata
The meaning of Gastrodia elata is called Red Arrow, Dingfeng Grass and Water Potato. It is a perennial herb of Orchidaceae. It is a valuable medicine for the treatment of nervous system diseases. The medicinal part is underground tuber, Gastrodia elata has the functions of calming down liver fire, tonifying qi, relieving shock, nourishing liver and relieving spasm. There is no significant difference in morphology and efficacy between Gastrodia elata cultivated in artificial tunnel and wild Gastrodia elata, so the development of artificial cultivation of Gastrodia elata is an effective measure to solve the decreasing of wild Gastrodia elata. The tunnel (or underground cave) is warm in winter and cool in summer, which is suitable for the growth and development of Gastrodia elata.

Cultivation methods of substitute materials for Gastrodia elata at low altitude (1)
Gastrodia elata is a kind of rare and precious traditional Chinese medicine, which used to rely on the wild and grow in the mountains above 500 meters above sea level. it is very rare and difficult to dig, and now it is facing extinction. The development of artificial cultivation of Gastrodia elata has saved this precious species, but technically it can not get rid of the cultivation at high altitude, and the raw materials can not be separated from the tree (oak), which makes the cultivation of Gastrodia elata has great regional limitations. Second, limited by the felling of forest resources, these two disadvantages have been perplexing the development of Gastrodia elata, which has never been able to form the modern Gastrodia elata.

Cultivation Method of Gastrodia elata by Substitution at Low Altitude (II)
After 18℃~22℃ culture, 2~3 months Armillaria mellea fungus cords string the whole corncob, then can be used for Tianma cultivation. If Armillaria mellea material is not enough, Armillaria mellea can be expanded and cultivated. This method is to add uncultivated corncobs to the corncobs cultivated by Armillaria mellea, the proportion is 50% respectively. The operation method is the same as above, and finally the soil is covered with bacteria. This method is simple and easy to use, without the need for original seeds, as long as the method is not affected by environmental conditions of high temperature and diseases and insect pests caused by degradation, variation, can be used for a long time cycle. five

Cultivation technique of Gastrodia elata in plastic bag
The cultivation of Gastrodia elata in plastic bags is usually carried out from October to November. 1. Polyethylene plastic bags with length of 45-50 cm and width of 28 cm are made by planting flax with bacteria sticks in plastic bags. The interior of the plastic bag is disinfected with 0.2% potassium permanganate aqueous solution, a small amount of basic culture material and small pieces of wood (preferably humus soil) are loaded at the bottom, and then two high-quality bacterial sticks with a diameter of 5-6 cm and a length of 20 cm are placed (if the diameter of the stick is greater than 7 cm, you can also put one). While filling the bag with humus.

How to produce high yield of Gastrodia elata cultivated outdoors
Artificial cultivation of Gastrodia elata has a wide range of adaptability, regardless of mountain height, shady slope, sunny slope, sandy soil and loess, Gastrodia elata production can be developed, so how to obtain high yield? ① is planted flat on the hillside. Autumn waterlogging and rainy mountain areas, cellar planting Gastrodia elata, in addition to a few places with good drainage, mostly due to stagnant water in the cellar resulting in reduced production of rotten hemp. Slope heap cultivation is easy to be affected by summer drought and high temperature because of its large area, which is not conducive to the growth of Armillaria mellea and Gastrodia elata, so it is difficult to obtain high yield. However, high yield can be obtained by border planting or horizontal cultivation. The method is: 25 ℃ above the slope, due to Rain Water

What are the conditions for artificial cultivation of Gastrodia elata
Artificial cultivation of Gastrodia elata should have the following five conditions: (1) it should have a box cellar with good ventilation and water permeability. (2) it is necessary to have exuberant Armillaria mellea and good fungus material. (3) there should be suitable culture materials for the growth of Gastrodia elata. (4) it is necessary to have excellent Gastrodia elata. (5) it is necessary to have a set of feasible cultivation and management techniques.

Why the yield of Pleurotus ostreatus is getting lower and lower?
Recently, many growers have called to consult: why is the production of Pleurotus ostreatus getting lower and lower? It's a lot worse than a few years ago. For this reason, the author conducted an investigation and found that there are the following problems: most of the growers are cultivated in the greenhouse year after year with serious environmental pollution, and the deterioration of environmental conditions and incomplete disinfection are the main reasons for the reduction of Pleurotus ostreatus production. According to the test, the base of miscellaneous bacteria in the new site is 63.95 per square meter, 95% of bacteria, and 150 colonies per square meter. At the end of the first cultivation, the number of miscellaneous bacteria will be 20 times higher than before.
