the purpose of the invention is to create a significant new way to the production of substrate, which would include the following: processing of raw materials, the containing u043b u0438 u0433 u043d u043e u0446 u0435 u043b u043b u044e u043b u043e u0437 u0443 (such as straw), using the methods of the main processing (for example, a steam explosion)to split the source material for the components of lower level; and the possible removal of carbohydrates from the treated group c5 mass u043b u0438 u0433 u043d u043e u0446 u0435 u043b u043b u044e u043b u043e u0437 u044b; u044d u043a u0441 u0442 u0440 u0443 u0437 u0438 i, pasteurization and sterilization of the primary substrate; an additive components to u0441 u043c u043e u0447 u0435 u043d u043d u043e u043c u0443 primary substratum, enrichment materialsnecessary for the growth of mushroom mycelium and mycelium; u043f u043e u0434 u0441 u0435 u0438 u0432 u0430 u043d u0438 u0435 and mixing of the finished substrate. substrate selectivity and resistance to diseases can be improved by planting and cultivation of u043b u0438 u0433 u043d u0438 u043d u0446 u0435 u043b u043b u044e u043b u043e u0437 u044b (treated with the above-mentioned methods) u0442 u0435 u0440 u043c u043e u0444 u0438 u043b u044c u043d u044b u043c u0438 mushroom development which corresponds to the optimum temperature of 45 u00b0 u0441.the number of useful derivatives / complex compounds of pulp and u0433 u0435 u043c u0438 u0446 u0435 u043b u043b u044e u043b u043e u0437 u044b approximately twice the size of the substrate by using the the new method in comparison with the substrate.which is made by conventional method u043f u0440 u0438 u043c u0435 u043d u0435 u0438 u044f composting; the preparation of a new substrate significantly shorter; during the preparation of the new u0441 u0443 u0431 u0441 u0442 u0440 u0430 the u043b u0438 u0433 u043d u043e u0446 u0435 u043b u043b u044e u043b u043e u0437 u0430 out artificially to the desired level of decomposit
