Problems solved by technology

The company introduced advanced solid-liquid separation equipment from Germany, which can successfully separate the biogas slurry and biogas residue produced in the biogas fermentation process. The biogas slurry has been used in the production of organic vegetables in the vegetable garden, and the biogas residue is used as a substrate, but still Nearly 20 tons of biogas residues cannot be processed

Abstract

The invention discloses a needle mushroom culture material. The needle mushroom culture material comprises large-scale methane residues serving as main raw materials and also comprises one or more of sawdust, corncobs or cottonseed hulls, and bran and gypsum. The culture material is used for cultivating the needle mushroom, so that the cost of the raw materials produced in a needle mushroom plant is reduced, the production cycle is shortened, energy consumption is reduced, the residues, namely methane residues, generated by large-scale fermentation of the methane can be recycled, and the circulation chain of biomass energy is lengthened.

Description

technical field [0001] The invention relates to the field of edible fungus cultivation, in particular to a culture material for Flammulina velutipes using industrialized large-scale biogas fermentation waste—big residue as a raw material. Background technique [0002] my country is the country with the fastest biogas development speed, the largest construction scale and the largest number of people involved in the world. According to the statistics of the Ministry of Agriculture, by the end of 2010, more than 56,000 biogas projects of various types had been built in farmers, breeding communities, and commercial farms, forming an annual production capacity of 14 billion cubic meters of biogas, which is a contribution to my country. Low-carbon economy and energy conservation and emission reduction have played an irreplaceable role. According to the calculation method of the National Energy Administration, every cubic meter of biogas can consume 2.5 kilograms of straw and produ...
