Cultivation Methods and Technical Key Points for Gastrodia Seed Material
Gastrodia cannot nourish itself; it must rely on a symbiotic relationship with Armillaria mellea (honey fungus) to obtain nutrients for reproduction and growth. The parasitic Armillaria mellea can grow on about 200 species of tree trees, especially broadleaf forests. Generally, Armillaria mellea grows from the roots of cut trees, bamboo, or burned trees and bamboo, as well as dead trees fallen in the forest. Armillaria mellea must grow vigorously under certain moist conditions; soil moisture content should be no less than 45%-50%, and relative air humidity of 75%-80% is suitable. Armillaria mellea can also be cultured artificially, but the spawn must first be

Detailed Explanation of the Key Technical Points of the Fixed Bacterial Material Companion Planting Method for Gastrodia elata
The fixed bacterial material companion planting method for Gastrodia elata, also called the fixed material cultivation method, uses pits or boxes to cultivate 2 to 3 layers of bacterial material before planting the gastrodia. When planting, first remove the covering from the pit or box, take out the upper bacterial sticks layer by layer, leave the bottom layer of bacterial sticks undisturbed, then gently pull out the middle bacterial sticks, leaving one and skipping one, replace them with new wooden sticks, and plant the seed gastrodia close against both sides and both ends of the bacterial sticks. The spacing for planting large white gastrodia is 20 to 25 cm, for medium white gastrodia 7 to 9 cm, for small white gastrodia 4 to 6 cm, and rice gastrodia is broadcast scattered. Be careful to place the gastrodia seed close to where the fungal strands of the seedlings are dense. After planting the gastrodia, cover with soil
