How to store gastrodia elata for winter
Hemp seeds can be kept in the cellar. First dig a pit in the cellar, the size of the pit depends on the number of hemp species, the pit depth is 45-50 cm. The vegetative breeding stem of hemp seed should be removed and hung for 1-2 days before entering the cellar. Choose sand with a moisture content of 20% as filling material. Too much water content and too small water content of sand are disadvantageous to hemp seed. After the pit is dug, the bottom layer (3 cm thick) of millet grain to sorghum grain of sand, put a layer of hemp seed, a total of 4-5 layers of hemp seed, the top layer covered with 5-6 cm thick sand. Each layer of hemp must be a simple pendulum, hemp and hemp do not touch each other, the gap is filled with sand.
During storage, the pit temperature was controlled at 1-6 ℃. To prevent freezing, you can cover the sand with a layer of leaves and sawdust. But it is also necessary to prevent the pit temperature from getting too high.

How to sow Gastrodia elata seeds with bacterial solution
(1) prepare the bacterial bed and begin to prepare the bacterial bed in April. Because of the low temperature in Northeast China, Gastrodia elata planted outdoors in winter is easy to suffer frost damage, so wooden boxes are used to grow Gastrodia elata, and wooden boxes are used as bacterial beds. Put a layer of basic culture material at the bottom of the wooden box, then put 5 high-quality bacterial sticks, fill the blanks with humus soil or sawdust Gaza (3:1), cover them with 18 cm thick, semi-rotten branches and leaves, water and keep warm, wait for the seeds to be collected, and sow the seeds. (2) the liquid Armillaria mellea strains with good culture materials were obtained by sowing method and diluted slightly with aseptic water. Will be just

Cultivation of Gastrodia elata seed material
Gastrodia elata can not be autotrophic and must rely on Armillaria mellea symbiosis with it in order to get nutrition and reproduction and growth. Parasitic Armillaria mellea can grow on about 200 tree species, especially in broad-leaved forests. Armillaria mellea is commonly found in cut trees, bamboo or burned trees, roots of bamboo, and dead trees that fall in the forest. Armillaria mellea can only grow vigorously under certain humid conditions, the soil water content is not less than 45%-50%, and the air relative humidity is 75%-80%. Armillaria mellea can also be cultivated artificially, which must be cultivated first.
