What does the single-layer box cultivation method for Gastrodia elata mean?

First put a layer of growing medium on the bottom of the box, about 6 cm thick, place 5 high-quality fungus sticks at equal distances along the length of the box, and sprinkle growing medium between the fungus sticks so that the fungus sticks are half buried and half exposed. Do not plant Gastrodia elata in the gaps between the fungus sticks and the box boards; instead, plant 4 rows of Gastrodia elata in the gaps between the fungus sticks, or also plant Gastrodia elata between the fungus sticks and the box boards, in which case 6 rows can be planted. Place the seed tubers right beside the fungus sticks, close against them. In order to give Gastrodia elata a sufficient nutrient supply, add 5 to 6 fungus branches between the fungus sticks, then fill in the base growing medium up to half the box. In order to use the effective space of the box more rationally, a layer of fresh fungus material should first be placed, then growing medium added until the box is full. After 1 to 2 months of cultivation, these upper-layer fungus materials can be cultivated into fungus sticks. The fungus sticks can then be used to cultivate Gastrodia elata again or used for expanding fungus, both are fine.
