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 level with the bacterial sticks, cover with 3 cm of culture material, then place the second layer of bacterial sticks and wooden sticks at intervals, then cover with 8 to 10 cm of culture material, and cover the top with fallen leaves and weeds. This method reduces damage to the combination of fungal strands and gastrodia bodies, and therefore has the characteristics of fast fungal-gastrodia combination, high yield, and labor saving, and should be popularized and promoted.
