Techniques of box cultivation of Gastrodia elata
(1) wooden box specifications are usually 60 cm long, 40 cm wide, 30 cm high wooden box for the container, the two ends of the box equipped with handles, easy to handle.
(2) loading and planting in the wooden box first spread a piece of plastic film larger than the surface area of the wooden box, and then spread a layer of moisture of 45% of the river sand, humus soil and sawdust mixture on the film, and then every 5 cm or so, with a fresh material and a root of bacteria separated discharge in the box, the gap is filled with mixture, so that the fresh material and bacteria bed are half-buried state. Between the fungus material and the fresh material, place one seed hemp grain every 8 - 10 cm, spread a layer of 4 - 6 cm mixture after planting, and cover with a film. a plurality of two-layer gastrodia elata seeds, wherein the fresh materials and the fungus materials of the second layer are correspondingly discharged with the fresh materials and the fungus beds of the first layer.
(3) The management temperature is kept at about 22℃. In order to prevent box planting due to rapid evaporation of water, frequent watering caused by mixture hardening airtight, you can insert a 32 cm long in each box. A pipe with a diameter of 1.5 cm is inserted directly from the material surface to the bottom of the tank. When watering each time, 300~500 ml of water is injected from the nozzle. Water penetrates into the mixture at the bottom, and then evaporates upward from the bottom. Shade can keep the mixture moist, loose and breathable.

Cultivation of Gastrodia elata by electromagnetic field
In the practice of cultivating Gastrodia elata, it is found that Gastrodia elata has high quality and high yield in the cultivation area stimulated by nature lightning. According to this phenomenon, the asexual reproduction and cultivation experiment of Gastrodia elata was carried out by simulating natural electromagnetic field, and the high benefit of average yield of Gastrodia elata per square meter was more than 10 kg per square meter, some as high as 20 kg for several years. The cultivation time and species selection of Gastrodia elata are generally cultivated in the hibernating period of Gastrodia elata. That is, it can be autumn, winter or spring.

Some points for attention in the introduction of Gastrodia elata
1. Suitable conditions: Gastrodia elata has no roots and leaves, can not carry out photosynthesis, and relies on the supply of Armillaria mellea for vegetative growth and reproduction. Therefore, the first step of planting Gastrodia elata is to cultivate a certain number of high-quality Armillaria mellea, and the second step is to introduce and purchase Gastrodia elata species. And planted with Armillaria mellea in time. Second, the adaptability of the hybrid Gastrodia elata of "Wu X Hong" and "Hong X Wu" is stronger than that of traditional asexual reproduction, and it is suitable to be planted in all potato planting areas, and its method is as extensive and simple as planting potato. Do not compete with crops for land, fertilizer and labor. 3. Suitable species
