Flammulina velutipes cultivation method

The invention relates to a flammulina velutipes cultivation method. The method comprises the following steps of 1, preparation of a culture medium; 2, bagging of the culture medium; 3, sterilization of the culture medium; 4, inoculation of flammulina velutipes; 5, culturing of flammulina velutipes mycelia; 6, bag opening and mycelium stimulation; 7, bud pressing of flammulina velutipes; 8, management of flammulina velutipes in a growth period; 9, harvesting of flammulina velutipes. In a cultivation process, leftovers including fresh distiller's grains and broad bean powder are adopted for preparing the culture medium, the cost can be reduced by 30% or above to the maximum extent, and meanwhile the yield can be increased by 20-30%. Produced mushroom bodies of flammulina velutipes are crispy, tender and light yellow and have a high commodity value. Because the distiller's grains, broad bean shells and the broad bean powder all belong to waste materials from processing factories and can be purchased at a low cos
