The invention discloses a drying method of gastrodia elata pieces and belongs to the technical field of primary processing of medicinal plants. The method includes the steps of: steam-cooking fresh gastrodia elata which has been washed before, peeling the cooked gastrodia elata, cooling the gastrodia elata, cutting the gastrodia elata into pieces, smearing a drying agent onto the gastrodia elata pieces, wrapping the gastrodia elata pieces in food-grade paper to shape the gastrodia elata, and drying the gastrodia elata. Compared with a conventional method which dries a whole plant of the gastrodia elata, the method reduces drying time by 3-5 days. The dried gastrodia elata still have the shape before drying, thereby avoiding adulteration of low-grade gastrodia elata, so that the method greatly improves anti-fake capability and the gastrodia elata pieces are convenient to use. With the drying method, the gastrodia elata pieces are increased in content of gastrodin than that in a method of drying the whole plant of the gastrodia elata by more than 23% at least. Compared with a method of drying the gastrodia elata and then cutting the gastrodia elata into pieces, the method also effectively reduces cutting loss rate and has strong capability of assembling the gastrodia elata pieces into the whole plant of the gastrodia elata.
