Which method of growing Gastrodia elata in boxes is better?
The fixed bacterial-material planting method is superior to the double-layer planting method, and the double-layer planting method is superior to the single-layer planting method.
In the fixed bacterial-material planting method, the bottom layer of growing medium and the bacterial sticks are left undisturbed, so the grown rhizomorphs are not damaged; after planting the Gastrodia tubers, the rhizomorphs quickly grow onto the tuber bodies, which can promote a high yield of Gastrodia elata, and the yield produced is higher than with the other two methods.
The single-layer planting method is not as high-yielding as the double-layer planting method, so the fixed bacterial-material planting method and the double-layer planting method are recommended.
