(1) Low investment. Generally, all expenses in the first year (per sq m) are 27 to 28 yuan, while expenses in the second year are only about 4 yuan, because in the second year there is no longer any need to buy seed tubers and bulk spawn. If hardwoods such as Qinggang oak are used, cultivation can last 3 years, and softwoods can also be used for more than 2 years. Old fungal wood can also be used to cultivate Polyporus umbellatus and the like, so as to achieve comprehensive utilization and the goal of improving economic returns. (2) Quick results. When white-headed tubers are used as seed for cultivation, it takes 8 to 10 months indoors, while outdoor cultivation requires only 1 year to harvest. (3) Material use

(2) Quick results. When white-headed tubers are used as seed for cultivation, it takes 8 to 10 months indoors, while outdoor cultivation requires only 1 year to harvest.

(3) Economical in material use. In the past, artificial cultivation of Gastrodia elata used large pieces of wood as fungal wood, which caused considerable waste. When wood is in short supply, branches and forks can be used to cultivate Gastrodia elata. According to experiments in Ningqiang County, Shaanxi Province, using small branches with a diameter of 2 to 3 cm as fungal wood has the advantages of saving wood, lowering costs, fast inoculation, short fungal cultivation time, high nutrient utilization rate, and remarkable economic returns.

(4) Large returns. Under normal circumstances, each sq m of Gastrodia elata can yield 5 to 12 kg in one year, with the highest reaching more than 15 kg, equivalent to 100 to 240 yuan, and the economic returns are very considerable.

(5) Simple operation and convenient management. As long as the technique is mastered, after Gastrodia elata is planted, there is no need to hoe weeds or apply fertilizer; the main tasks are preventing drought, preventing cold, preventing high temperatures, preventing waterlogging, and preserving soil moisture, with no need to spend too much labor.
