How to use wide mouth bottle to cultivate Gastrodia elata
Bed frame requirements: bed frame and indoor cultivation of Gastrodia elata bed frame form is basically the same, but each bed frame distance of 30 cm, put 10-12 layers, do not need to do hoarding around. The bottom layer can be made of wood or straw curtains.
The jar is 18 cm high, 8 cm in diameter and 4 cm in diameter.
Cultivation method: the culture materials for cultivating secondary solid bacteria were packed in a wide-mouth bottle and filled to a little more than 3% of the bottle volume, then sterilized under high pressure. After cooling, secondary Armillaria mellea was added and cultured in 19-22 ℃ greenhouse for 30 days to become the culture medium for Armillaria mellea. On each bottle of Armillaria mellea culture medium, put the basic culture material (the basic culture material is best to use humus soil with less fine sand and small wood blocks, or sawdust, semi-rotten deciduous leaves and small wood blocks with a humidity of 50% Mel 55%) 3 cm thick. Then put 3 pieces of rice flax into the culture material at the same distance, and the terminal bud is outward. Then put the culture material into the shoulder of the bottle and plug it with a cotton stopper for culture. The whole culture period takes 8-12 months.

How to prevent low yield of Gastrodia elata
First, the quality of Armillaria mellea is poor. Most farmers are used to using the old sticks planted last year to grow Gastrodia elata, that is, the old stick plus new stick method to cultivate Gastrodia elata. The quality of the old wood is poor, not only most of the nutrients have been consumed and utilized, the aging phenomenon of Armillaria mellea is serious, but also there are many factors with miscellaneous mold, which not only do harm to the growth of Gastrodia elata, but also destroy the environmental conditions for the growth of Armillaria mellea. So that Armillaria mellea source can not provide good nutrition to Gastrodia elata, resulting in low yield and even no harvest. II. Application of multi-generation species with degenerated species

How to use rice husk to cultivate bacteria and cultivate Gastrodia elata
Rice husk is a good "soil" ingredient for bacteria culture and Gastrodia elata cultivation in plain area. Its "soil", namely filler, has the characteristics of looseness, ventilation, good water permeability, rich nutrition and conducive to the growth of Armillaria mellea. The fungal cords on the branches and materials cultivated with it are stout and exuberant, and the cultivated Gastrodia elata grows well. The method is as follows: (1) 1 part of rice husk and 1 part of yellow sand (volume ratio is 1:1) or 3 parts of rice husk and 2 parts of yellow sand for fungal culture of rice husk, mix well with water and humidity 40%.
