The invention discloses a cultivation method of Auricularia auricular and belongs to the technical field of cultivation of agricultural products. Compost is prepared from raw materials in parts by weight as follows: 18-25 parts of corncobs, 30-40 parts of mulberry branch powder, 13-20 parts of ramie, 23-30 parts of bagasse, 2-5 parts of chestnut shells, 1-4 parts of gypsum, 10-25 parts of saw dust, 2-5 parts of sugar, 2-5 parts of dihydrogen phosphate, 1-4 parts of magnesium sulfate and a proper amount of water. The specific cultivation process is as follows: preparation of the compost, bagging, sterilization, inoculation, culture, fruiting management, growth management and harvesting. The Auricularia auricular cultivated with the method has the advantages of high yield, low planting cost, high survival rate, high growth speed, high quality and the like; the compost adopts local waste such as the mulberry branch powder, the chestnut shells and the ramie, so that the cultivated Auricularia auricular has the good quality and the good taste; micro-element liquid fertilizer is sprayed in the cultivation process, the yield of the Auricularia auricular is increased, and the nutritional value of the Auricularia auricular is increased.
