Artificial cultivation of Gastrodia elata mainly uses the trunks of broadleaf trees such as oak, birch, hazel, elm, willow, jujube, pagoda tree, and wild cherry, and requires a diameter of more than 5 cm. For a long time, this has caused severe damage to forest resources, which are now on the verge of exhaustion. Therefore, research on substrate replacement cultivation techniques for Gastrodia elata has gradually become a hot topic. There are already precedents for substrate replacement cultivation using corn cobs, shrub stems, corn cobs, corn pith, branches, and straw, but no reports on the cultivation of Gastrodia elata with cottonseed hulls have been seen. For this reason, this trial was conducted, and the preliminary results are reported as follows: 1 Materials and
