Method for preparing agaricus bisporus compost by taking rice straw as raw material through three-time fermentation

The invention discloses a method for preparing agaricus bisporus compost by taking rice straw as a raw material through three-time fermentation, and relates to a preparation method of the agaricus bisporus compost, in particular to the method for preparing the agaricus bisporus compost by taking the rice straw as the raw material through three-time fermentation. The method aims to solve the problem of high cost of preparing the agaricus bisporus compost by taking wheat straw as a raw material through three-time fermentation in the prior art. The method comprises the following steps of 1, weighing materials; 2, pre-wetting; 3, mixing the materials; 4, performing primary fermentation; 5, performing secondary fermentation; 6, performing third-time fermentation; and 7, discharging to obtain the agaricus bisporus compost. The method has the advantages that the agaricus bisporus compost is successfully prepared by adopting the rice straw instead of part of wheat straw and adopting a three-time fermentation process;
