1. Land selection and soil preparation: it is advisable to choose gentle slopes with half shade and half sunshine and valleys rich in organic matter for planting. The soil quality is well-drained loose loam, sandy loam or sandy soil, especially raw wasteland. The pH value of the soil is 5 ~ 6. Avoid clay, waterlogging and continuous cropping. In addition, Gastrodia elata can also be planted in bomb shelters, caves, basements and other places. 2. Propagation mode: mainly tubers, but also seeds. (1) tuber propagation: winter or spring. Gastrodia elata in winter has high inoculation rate and fast growth, and the time is 1 1 month. Spring is planted from March to April. Culture bed before planting. Commonly used tree species suitable for the growth of Armillaria mellea, such as Phyllostachys pubescens, oak, Quercus variabilis, chestnut, etc. The broad-leaved trees with thick bark, hard nature and strong corrosion resistance are better. 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 at intervals between the treated new wooden sticks and the wood with Armillaria mellea (commonly known as fungus material), with the distance between two adjacent wooden sticks being 6-7 cm, and some branches of broad-leaved trees sandwiched in the middle, and filling the gaps with humus soil to prevent the pollution of miscellaneous bacteria, and covering the soil for 3-4 cm. 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, 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. (2) Seed propagation: Gastrodia elata whose weight is more than 100g is selected, harvested and planted according to the above method, and it should be protected from light when heading, and artificially pollinated 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 the 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 into the fungus material soil layer, and finally cover them with10 ~ 65438. For example, 8 ~ 65,438+00 capsules, each cellar can be seeded with 65,438+00 fungus materials, 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.
