What is the key to artificial cultivation of Gastrodia elata
(1) the nutrition of Gastrodia elata comes from fungus material, so the cultivated fungus material is free of miscellaneous bacteria, the second is that the fungal cord is dense and tender, and the third is that it can not be aged.
(2) for the application of local seeds, they should be harvested and planted, and the storage time should not be too long; foreign seeds should not be collided during transportation, and should be planted with a layer of mud moss and a layer of Gastrodia elata, and the transportation and storage time should be reduced as much as possible.
(3) when planting, the hemp seed must be close to the fungus material and placed in the place where the fungal cord is dense. Cover the soil lightly and be careful not to detach the flax fungus.
(4) cover the soil with sandy soil or a mixture of wheat bran, sawdust and soil with a thickness of 15cm to 20cm.
(5) according to the local climate, in winter, the nest or border cellar should be covered with 15-20 cm thick sawdust or 15-20 cm thick rotten, semi-rotten fallen leaves; warm areas should be covered with a layer of wheat straw, straw or corn stalks.
(6) the drainage ditch should be controlled around Woti in the rainy season, and the ditch is deeper than Woti. Wanzi should strictly prohibit the trampling of people and animals.
(7) more fixed bacterial beds should be built from June to August.

What are the technical elements of artificially cultivated Gastrodia elata
(1) change the wild into home planting. (2) adopt single-layer and double-layer cultivation, and further develop into three-layer cultivation. (3) the covering material was added to the upper and lower layers by the method of co-planting with bacterial material, so that the fungal cord grew both upward and downward, and the middle fungal cord was interwoven into a network, which was more beneficial to the growth of Gastrodia elata. (4) when using big branches as fungus material, we should pay attention to using small branches, which not only saves wood, but also facilitates local use of materials in plain areas and makes full use of raw materials. (5) cultivation in wooden boxes and brick ponds

Control of miscellaneous bacteria in Gastrodia elata
1. Check the branches and sticks carefully when cultivating the fungus. As miscellaneous bacteria like saprophytic life, fresh wood culture sticks without decay and mildew should be selected, and the culture time should be shortened as much as possible. If miscellaneous bacteria are found on the stick, scrape off the light ones and bask in the sun for 1-2 days; the heavy ones will be discarded. 2. Check the kinds of hemp used. If mold infection is found, light ones should be scraped off, insolated, or used after local disinfection with 75% alcohol, carbendazim and so on. All bruised and moldy hemp seeds will be abandoned. 3. The fillings should be filled and must not be left.
