Cultivation of Gastrodia elata

Gastrodia elata needs to be born on rotten wood with the fungus Armillaria mellea, and relies on fungal hyphae to invade the root system to absorb nutrients. Therefore, it is necessary to choose the wood for the growth of Armillaria mellea, and the thick wood with hard wood is more suitable, such as Cyclobalanopsis glauca, oak, birch, alder and chestnut. After selecting the tree species, cut the wood into large sections, cut a small mouth every ten centimeters, and arrange it in a fish-scale shape as a whole.

after inoculating Armillaria mellea, arrange the pieces of wood in two layers in the pit, fill the layers with humus soil, keep proper temperature and humidity, and the Armillaria mellea can grow after 2-4 months, then remove the rotten Armillaria mellea and keep the well-grown Armillaria mellea. When sowing, plant hemp seeds between the two layers of fungi and fill the soil again. If seeds or capsules are used for sexual reproduction, the above method can also be adopted, and it is only necessary to put more covers such as leaves and humus between the two layers of fungus materials when sowing. Gastrodia elata is dormant from mid-October to April of the following year, so the harvest should be carried out during this period, and the sowing time should be selected around mid-October < P > Baidu Encyclopedia-Gastrodia elata.
