Plant in winter or spring. Gastrodia elata in winter has high inoculation rate and fast growth, and the time is 1 1 month. Plant spring in March-April. Culture bed before planting. Commonly used tree species suitable for the growth of Armillaria mellea, such as Cyclobalanopsis glabra, Quercus variabilis, Castanea mollissima, etc. Thick bark, hard wood and strong corrosion resistance are the best.

Saw the selected wood into sticks 40-50 cm long and cut the bark into fish scales. In the selected plot, 2-3 months before planting, dig a pit with a depth of 25-30 cm, a width of 60 cm and a length depending on the terrain. Leveling the bottom of the cellar, spreading a layer of dry leaves or humus soil, placing 1 layer between the treated new wooden stick and the wood with Armillaria mellea (commonly known as fungus material), with the distance between two adjacent wooden sticks being 6-7cm, placing some branches of broad-leaved trees in the middle, filling gaps with humus soil to prevent contamination by miscellaneous bacteria, and covering with soil for 3-4cm. Similarly, place the second layer and cover it with 10 cm soil. Keep the cellar moist, cover it with weeds for shade, cool and moisturize, and let Armillaria grow normally, that is, form a fungus bed. Tubers without disease spots, freezing injury and rot are selected as seed plants and cultivated separately. When planting, put the seed hemp into the ditch between the fungus sticks in parallel, close to the fungus sticks, fill the gap with humus soil, and cover it with 3 cm to avoid seeing the bottom fungus. The second layer is planted in the same way, and finally covered with 10- 15 cm, and covered with a layer of leaf weeds to keep the soil moist, and the covering layer is thickened during wintering to prevent freezing injury. If artificial bacterial beds and plastic bags are used for cultivation, the seed hemp used is white hemp and rice hemp, and the cultivation time can be from 1 1 to April of the following year, because the temperature is artificially controlled.

Seed propagation

Gastrodia elata, weighing more than 100g, should be harvested and planted. Avoid light when heading, and pollinate artificially when flowering. Pollination time can be around 10 in sunny days, when the edge of the drug cap is slightly flowered. After pollination, cover the ear with plastic bags, and when a small amount of seeds are sown on the lower fruit, harvest it from bottom to top as it matures.

Due to the short life span of gastrodia elata seeds, the harvested capsules should be sown in time. When sowing, take out the upper fungus material on the fungus bed, scrape off the soil on the lower fungus material, spread withered and wet leaves on the lower fungus material, flatten them slightly, spread the seeds evenly on the leaves, cover them with a thin layer of wet fallen leaves, sow the second layer of seeds, cover them with 3 cm of soil, cover them with a layer of wet leaves, put them in the soil layer of fungus material, and finally cover them with10-655. For example, 8-65,438+00 capsules, each cellar can be seeded with 65,438+00 fungi, and each capsule has about 30,000 seeds. If planted properly, a part of arrowroot, white hemp, seed hemp and a large amount of rice hemp can be received in the next autumn, which can be used as seed potatoes for tuber propagation.
