The invention relates to a method for preparing
auricularia polytricha culture material, needing the following materials by the weight percent: 35-55 of cotton seed hulls, 25-45 of rice
bran, 10-16 percent of mixed wood dust, 1.5-2 percent of corn cob, 0.5-1 of
straw, 0.5-1
calcium superphosphate, 0.5-1 of plaster, 1.5-2 of beanstalk
powder, 0.1-0.3 of
oxygen increasing
powder, 0.1-0.3 of nitro-
phosphor-
potash compound
fertilizer, 0.1-0.3 of mold resisting liquid and 0.5-0.8 of
calcium superphosphate. The method for preparing
auricularia polytricha culture material comprises the following steps: the cotton seed hulls, the rice
bran, the mixed wood dust, the corn cob, the
straw and the beanstalk
powder are taken according to the weight percent, mixed together and poured into a
pulverizer to be pulverized into mixture with granules of about 80 meshes; the mixture is taken out; the superphosphate, the plaster, the
oxygen increasing powder, the nitro-
phosphor-
potash compound
fertilizer, the mold resisting liquid and the
calcium superphosphate are added to the mixture; the new mixture is poured into a stirrer to be stirred for about 70 min; the stirred mixture is taken out and then put into a
fermentation tank; water is added to the stirred mixture at the ratio of 1:1.2-1.3; and the stirred mixture is stirred again and stacked; and the stacked mixture is sealed by a thick
plastic film to be fermented for 10-12h, therefore, the qualified
auricularia polytricha culture material is prepared.
