The invention discloses a preparing technology for an
agaricus bisporus culture medium. Rotten
hardwood leaves,
pleurotus eryngii dregs and shii-take dregs serve as raw materials, and
lime and
gypsum serve as auxiliary materials. The preparing technology includes the following steps that 1, the
hardwood leaves falling to the ground are collected and are exposed in the sun to remove parts of infectious microbes and parts of injurious insects; 2, the exposed leaves are soaked in
lime water of 2% for 12 h and taken out; 3,
waste material collection is carried out, wherein normal
mushroom-harvested
pleurotus-eryngii and shii-take bags without infectious microbe
pollution are selected and removed, and dregs are uniformly collected; 4, waste materials are smashed, wherein the
pleurotus eryngii dregs and the shii-take dregs obtained after bag removing are dried in the sun and then smashed into particles with the
diameter of 0.3-0.6 cm; 5, piling is carried out, wherein the materials are mixed and piled, the
pile comprises a layer of the
pleurotus eryngii dregs with the thickness of 3 cm, a layer of the leaves with the thickness of 2 cm and a layer of the shii-take dregs with the thickness of 3 cm, watering is carried out every time one layer is piled till water flows out of the
pile, the width of the
pile is 1.5-2 m, and the height of the pile is 1.5 m; 6, first-time
fermentation is carried out; 7, second-time
fermentation is carried out; 8, inoculating is carried out.
