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

Embodiment 1

[0036] Take by weighing biogas residue 50kg, corn cob 30kg, bran 13kg, corn flour 5kg, gypsum 2kg respectively, and its dry material weight percent is biogas residue 50%, corncob 30%, bran 13%, corn flour 5%, gypsum is 2%. Stir the dry material evenly, then add water and stir until it is completely mixed, so that the water content reaches 55%-60%, bottle it with a machine, about 700g of wet material per bottle, autoclave at 121°C for 2 hours, and artificially inoculate Coprinus comatus The strains (inoculum size 3% V / V) were cultured (cultivation conditions were temperature 23°C, humidity 65%-75%, CO 2 Concentration of 1500ppm), dig the bottle after full of bacteria, dig the bottle and compact it in a 100cm*50cm*30cm basket. Mushrooms (the conditions for fruiting are temperature 16°C-18°C, humidity 91%-95%) to count indicators such as the germination period, harvested fruiting time, mushroom weight, biotransformation rate, and fruiting output per square meter .

Embodiment 2

[0038] Weigh 55kg of biogas residue, 25kg of corn cob, 13kg of bran, 5kg of corn flour, and 2kg of gypsum, and stir evenly. The weight percentage of the dry material is 55% of biogas residue, 25% of corn cob, 13% of bran, 5% of corn flour and 2% of gypsum. All the other are with embodiment 1.

Embodiment 3

[0040] Weigh 60kg of biogas residue, 20kg of corn cob, 13kg of bran, 5kg of corn flour, and 2kg of gypsum, mix them evenly, add 150kg of water and stir evenly. The weight percentage of the dry material is 60% of biogas residue, 20% of corn cob, 13% of bran, 5% of rice flour and 2% of gypsum. All the other are with embodiment 1.

Abstract

The invention discloses compost for the industrialized production of coprinus comatus. The compost comprises the following components in percentage by weight: 50-70% of biogas residue, 5-40% of corncob, 13% of bran, 5% of corn flour and 2% of gypsum. By using the compost provided by the invention for cultivating the coprinus comatus, the raw material costs for production of the coprinus comatus is reduced, the production cycle can be shortened, the yield can be improved, the energy consumption can be reduced, the biogas residue, the residue of large-scale methane fermentation can be recycle, and the circular chain of biomass energy can be prolonged.

Description

Technical field: [0001] The invention relates to the field of edible fungus cultivation, in particular to a culture material for industrial production of Coprinus comatus. 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 produce 0.8 to 1 kilogram of biogas residue. The amount of biogas resid...
