Artificial culture method and culture medium for fruiting bodies of cordyceps militaris

The invention discloses an artificial culture method and a culture medium for fruiting bodies of cordyceps militaris. Based on the culture medium in a 500mL culture bottle, the culture medium comprises the following components: 20 to 25g of cottonseed hull and 120 to 140mL of nutrient solution, wherein the nutrient solution comprises the following components in part by weight: 2.0 to 3.0 parts of wheat flour, 1.0 to 1.5 parts of soya flour, 3.0 to 4.0 parts of white sugar, 0.1 to 0.2 part of magnesium sulfate, 0.1 to 0.2 part of potassium dihydrogen phosphate, 0.05 to 0.1 part of zinc sulfate, 0.05 to 0.1 part of sodium chloride and 95 to 105 parts of water, and the pH value of the nutrient solution is 6 to 8. The artificial culture method comprises the following steps of: preparation of the culture medium, sub-packaging, sterilization, cooling, inoculation, culture and harvesting of fruiting bodies. The invention has the advantages of simple operation, high efficiency, energy conservation, short culture period, high yield of fruiting bodies, and no pollution or solid wastes.
