What are the technical elements of artificially cultivated Gastrodia elata
(1) change the wild into home planting.
(2) adopt single-layer and double-layer cultivation, and further develop into three-layer cultivation.
(3) the covering material was added to the upper and lower layers by the method of co-planting with bacterial material, so that the fungal cord grew both upward and downward, and the middle fungal cord was interwoven into a network, which was more beneficial to the growth of Gastrodia elata.
(4) when using big branches as fungus material, we should pay attention to using small branches, which not only saves wood, but also facilitates local use of materials in plain areas and makes full use of raw materials.
(5) using wooden box cultivation and brick pond cultivation, or directly heap planting, cellar planting and border planting without any container, so as to expand the planting range and reduce the production cost.
(6) in the formula of culture material, sawdust, river sand or sawdust 40%, river sand 30%, grain husk 30%, plus 0.01% potassium dihydrogen phosphate and magnesium sulfate were used as trace element supplements.

What are the characteristics of artificially cultivated Gastrodia elata
(1) small investment. Generally speaking, the total expenditure in that year (per square meter) is 27,28 yuan, while the expenditure in the second year is only about 4 yuan, because there is no need to buy hemp seeds and batch strains in the second year. If it is green bark tussah and other hard miscellaneous wood, can be cultivated for 3 years, cork can also be used for more than 2 years. Polyporus umbellatus can also be cultivated with old fungus materials in order to achieve comprehensive utilization and improve economic benefits. (2) the effect is quick. It takes 8 to 10 months indoors and only 1 year to harvest outdoors with white hemp as seed. (3) material

What is the key to artificial cultivation of Gastrodia elata
(1) the nutrition of Gastrodia elata comes from fungus material, so the cultivated fungus material is free of miscellaneous bacteria, the second is that the fungal cord is dense and tender, and the third is that it can not be aged. (2) for the application of local seeds, they should be harvested and planted, and the storage time should not be too long; foreign seeds should not be collided during transportation, and should be planted with a layer of mud moss and a layer of Gastrodia elata, and the transportation and storage time should be reduced as much as possible. (3) when planting, the hemp seed must be close to the fungus material and placed in the place where the fungal cord is dense. Cover the soil lightly and be careful not to detach the flax fungus.
