The invention discloses a method for producing
cordyceps militaris sporocarp and a fish
feed additive at the same time. A culture medium formula for producing the
cordyceps militaris sporocarp comprises liquid A and
solid B; the liquid A is prepared from the following components of 1000ml of water, 10.0 to 15.0g of saccharose, 0.3 to 0.5g of KH2PO4, 0.3 to 0.5g of MgSO4, four tablets of complex
vitamin B and 1 tablet of
vitamin C; the
solid B is prepared from the following materials of 50% of
wheat berry, 15% of
rapeseed meal, 24% of
peanut meal, 1% of dry silkworm chrysalis
meal and 10% of rice
bran; a ratio of the liquid A to the
solid B
powder is (2 to 3) to 1. The method comprises the steps of sealing, sterilizing and cooling the culture medium; then inoculating
cordyceps militaris strain, inoculating according to a volume ratio of the strain to the culture medium as 1 to 50 and performing dark culture at first and then performing light culture in cultivation, wherein a strain density is 10 to 20
fungus balls / mL; obtaining the sporocarp and fungi residues. A crude
polysaccharide content of the fungi residues reaches 27.43%, the fungi residues are naturally dried or stoved and then smashed to 80-mesh
granularity, and
digestion and absorption of fish bodies are facilitated; furthermore, the fungi residues have fragrant smell and can serve as the fish feed addition, and an adding amount is 10 to 15%.
