NOVELTY - Bed soil comprises first group ingredient including coco peat or peat moss, and second group ingredient including perlite or puffed rice hull, where the first group ingredient is mixed in 50-80% and the second group ingredient is mixed in 20-50%.    USE - The bed soil is useful for growing Gastrodia elata blume (claimed).    ADVANTAGE - The bed soil improves yield of the Gastrodia elata blume.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (I) producing sexual breeding progeny germinated from Gastrodia elata blume seed, comprising (a) drilling a hole to provide a drained well on a box or a container, spreading a sponge floor, spreading 5-10 cm the bed soil on the sponge floor and covering 1-2 cm with oak leaves, (b) simultaneously inoculating the Mycena sp. and Armillaria sp., and (c) planting the Gastrodia elata blume seed into the covered bed soil and re-covering 2-4 cm; (II) producing asexual breeding progeny, comprising (i) processing well draining in box or bed facility, spreading a sponge floor, and spreading 5-10 cm the bed soil on the sponge floor, (ii) cutting wood to a length of 9-11 cm and diameter of 9-10 cm, pre-inoculating the wood with the grown fungus, inoculating a fresh wood with fungus, and arranging the pre-inoculated wood and the freshly inoculated wood in zigzag manner, (iii) spreading the bed soil to height of the wood, and cover 2-3 cm with the bed soil, and (iv) maintaining temperature of 24-27 degrees C for 3-4 months, 10-24 degrees C for 2-3 months, 5-10 degrees C for 2-3 months, 24-27 degrees C for 3-4 months, 10-24 degrees C for 2-3 months and 5-10 degrees C for 2-3 months during dormancy, and the incubation period; and (III) producing asexual breed Gastrodia elata blume, comprising (v) processing well draining in box or bed facility, spreading a sponge floor, and spreading 5-10 cm the bed soil on the sponge floor, (vi) cutting wood to a length of 9-11 cm and diameter of 9-10 cm, pre-inoculating the wood with grown fungus, inoculating a fresh wood with fungus, and arranging the pre-inoculated wood and the freshly inoculated wood with a length 30-40 cm in zigzag manner, (vii) spreading the bed soil to height of the wood, and cover 2-3 cm with the bed soil, and (viii) maintaining temperature of 24-27 degrees C for 3-4 months, 10-24 degrees C for 2-3 months, 5-10 degrees C for 2-3 months, 24-27 degrees C for 3-4 months, 10-24 degrees C for 2-3 months and 5-10 degrees C for 2-3 months during dormancy, and the incubation period.
