1. Choose a place to grow Gastrodia elata. The site should have deep soil, loose soil, and good drainage. Sandy loam should be preferred. Huangdi, alfalfa land and gravel are generally not suitable for cultivation of gastrodia. The air on the site should be fresh, cool, and moist. Generally, it is better to use a shady slope or a tree under the forest. 2, the selection of good materials generally use the old and new ways. The old strains are still rich in nutrients and are free from bacteria, and the mycelium grows vigorously in brownish red or brown. It is better to cut down the new bacterial material after the "starting winter" and before the "equinox", and it will have long-term corrosion resistance and good bacterial transmission. Birch, eucalyptus and other perishable should not be used. 3. Normalize cultivation patterns. Remove debris and roots after selecting the site. Dig 1 m wide and 25 cm deep soil slot along the slope. The length is not limited. Then spread 2-3 cm of humus at the bottom, equine the new and old materials in a 1:1 layer with a 3-5 cm rod spacing, then fill half of the material and then cover with a little soil. The second floor, you can. Finally cover the top 10-15 cm, outside covered with leaves or weeds. This cultivation method uses 1 kg of seed hemp per square meter. 4. Cultivation and harvesting in proper period The planting will be carried out from late March to mid-April, and from mid-late October to early November. 5. Strengthen the Management of High Temperature Season After entering the high temperature season in mid-July, it is necessary to timely control or regulate the soil temperature and humidity according to the changes of the natural climate. For example, watering should be done when the drought occurs, and pouring should be done less frequently; when it rains, it should be drained in time. Covering foliage or weeds can both shade and increase sensation. 6. It is best to keep the winter cold gastrodia species with fresh, undamaged, mildew-free, disease-free spots, pulpy feet, ring-reeds, round heads and yellow buds. When winter storage, it should be frost-proof, and it is usually stored indoors or outdoors in the cellar. The temperature is preferably 2-4°C and the humidity is 30%-40%. Use a slightly moist clean sand as a filler, piled up in layers, with no contact between the gastrodia. Indoors can be stacked directly, wooden boxes, woven baskets, etc. can also be used.
