Culture medium material of straw-raw-material marsh gas production slag for cultivating bisporic mushroom and preparation method thereof

Abstract

The invention relates to a culturing base material and preparing method for growing agaricus bisporus which uses marsh dregs from straw raw material to produce marsh gas. The raw material component for culturing base material comprises marsh dregs, dairy manure, bean cake powder, lime powder, plaster powder, light calcium carbonate, ordinary superphosphate and carbamide. The marsh dregs of straw raw material is taken out, drained, processed in aerobic condition and dried to a condition of water ratio lower than 65 percent or the marsh dregs are sunned and dried to condition water ratio of lower than 15 percent for storage and backup. The invention achieves reuse of marsh dregs to a maximum extent, therefore, growing raw material source is widened to achieve the agaricus bisporus growing raw material source with reliability, universality and growing high yielding. The normal growing cost is decreased by around 50 percent and output is raised by 10 percent. The invention is beneficial to develop circular economy and in accordance with the demand for searching and using new raw material resources of edible fungi industrialization development at the present stage.

Description

Technical field [0001] The invention relates to a method for utilizing biogas residue, in particular to a culture medium for cultivating Agaricus bisporus using biogas residue from straw raw materials to produce biogas and a preparation method thereof, belonging to the technical field of cultivating Agaricus bisporus using new raw material resources. Background technique [0002] The traditional cultivation of Agaricus bisporus mainly uses straw materials such as cottonseed hulls, wheat straw, rice straw and animal manure such as cow manure and pig manure as cultivation materials. For example, CN1788540 disclosed the composition of the medium for Agaricus bisporus: 45-55% of forage and 35-45 for manure. %, cake fertilizer 1-8%, urea 0.5-1.0%, raw gypsum powder 0.5-1.5%, superphosphate 0.8-1.5%, quicklime powder 0.2-1.5%, calcium carbonate 0-2.0%, dichlorvos 0-0.5%, of which The combined amount of forage and manure shall not be less than 90% of the total weight of the raw material...

AI Technical Summary

Problems solved by technology

Due to the limitation of resources and other conditions, the production of Agaricus bisporus cannot be ideally developed, resulting in the current contradiction between supply and demand. The main reasons are: on the one hand, with the emergence of energy problems, as a biomass resource, the utilization channel of crop straw There are more and more, and the use value is also increasing. Straw, which was once regarded as waste, has now become a new resource that has been widely valued. After the raw materials are fermented to obtain biogas, a large amount of straw resources will be consumed; that is to say, the contradictions such as competition between mushrooms and livestock and mushrooms and marshes have become increasingly prominent

On the other hand, when the straw produces biogas, it also produces a large amount of biogas residue, which is either directly thrown into the farmland or discarded, and the utilization efficiency is not high
