On the surface, this cultivation method is convenient for centralized management and can also increase production. In fact, it has many disadvantages: 1. Weak ability to resist natural disasters, such as drought and waterlogging, resulting in increased labor
2. Due to the impact of hygienic conditions in front of and behind the house, Gastrodia elata is vulnerable to pests and diseases, resulting in a reduction in pro...

[0018] 1. Site selection: choose the barren hills and slopes where wild Gastrodia elata grows and distributes, and the shade of trees is 70-80%. Generally, it is selected in the northeast or northwest of the mountain forest, and the north is the most suitable.
[0019] 2. Hole opening: the area of the hole is generally 0.5m 2 , The depth of the hole is 25-30cm, and the distance between the holes is about 2m. According to local conditions, the growth of trees must not be affected. The soil at the bottom of the hole is loosened, planed, and sprinkled with quicklime to kill insects and sterilize.
[0020] 3. Seed selection: it must be wild gastrodia elata produced through sexual reproduction and cultivated within 3 generations of hemp seeds, remove diseases, insect pests, and damaged hemp seeds, and divide the hemp seeds into four grades,
[0021] Each of the first grades weighs more than 15g, each of the second g...

Abstract
The invention relates to an imitative wild cultivation technique of gastrodia, comprising site selection, hollow opening, seed selection, fungus material spread, gastrodia seeds placing, three-grade armillaria mellea placing, humus soil covering and cultivation conducting. The technique results from field study and research, a large number of repeated experiments and explorations in the practice of cultivation by a plurality of years and can stabilize the yield of the gastrodia, particularly improve the quality of the gastrodia cultivation with good appearance and character, close to the wild state. In addition, taking full advantage of the superior natural environment, the technique reduces drop in production caused by bacteria invading, improves the capacity of the gastrodia to combat natural adversities, reduces cost by getting materials from local resources and makes up for the shortage of large field cultivation so as to resolve the land contention with the farmland, promoting the development of the special industry of underwood planting of the ecological agriculture.
