How to sow Gastrodia elata seeds with bacterial solution
(1) prepare the bacterial bed
The preparation of the bacterial bed began 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. The newly collected Gastrodia elata seeds were poured into the bacteria and soaked for 7-8 hours. Remove the dead branches and leaves from the bacteria bed, and immediately sprinkle the bacteria liquid and bacteria evenly on the sticks of the prepared bacteria bed. Then put the original semi-rotten dead branches and leaves back to the original place, and then cover 4 cm thick humus soil. Or take half of the original semi-rotten withered branches and leaves, leave half of the layer, and spread the liquid strains of Armillaria mellea with Gastrodia elata seeds directly and evenly on the fallen leaves. Then take back the other part of the fallen leaves, put them flat, and cover them with 4-6 cm thick humus soil. By using this method, Gastrodia elata seeds have high germination rate, high survival rate and rapid growth.
