Problems solved by technology

[0002] In the traditional cultivation of Agaricus bisporus, crop stalks and animal manure are mostly used as cultivation base materials after adding water and fermenting. In recent years, rural biogas has made great progress. While producing biogas, a large amount of biogas slurry is also produced, and part of the biogas slurry is directly put into the Most of the farmland is discarded, causing secondary pollution, and its utilization value has not been fully reflected. To a certain extent, it has wasted great resources; To maximize the comprehensive effect of biogas construction to meet the requirements of developing circular economy and building new countryside? We combine biogas slurry with the cultivation of Agaricus bisporus to achieve the purpose of using "waste" and protecting the environment on the one hand, and improving the cultivation effect of Agaricus bisporus as new nutrients on the one hand. This is in line with the policy of new energy and new material development and utilization. Adapting to the direction of comprehensive utilization of rural biomass resources is of great significance to the healthy development of edible fungi industrialization

Embodiment 1

[0027] Embodiment 1: the culture medium of biogas slurry cultivation Agaricus bisporus, component is as follows, parts by weight:

[0028] 840 parts of biogas slurry, 300 parts of wheat straw, 300 parts of cow dung powder, 12 parts of superphosphate, 2 parts of urea, 30 parts of lime powder, 6 parts of gypsum powder, and 6 parts of calcium carbonate.

[0029] The preparation method of culture medium is as follows:

[0030] The biogas slurry is taken from a biogas digester that produces gas normally and has been in operation for more than three months after a major refueling. The measured pH value is 7±0.5, fully decomposed, dark brown in color, and a layer of brown bubbles is densely covered on the surface of the biogas slurry in the biogas digester. , Put the fresh biogas slurry into the cement pond and allow it to be naturally aerated for 10 days; according to the cultivation formula of Agaricus bisporus, add the aerated biogas slurry together with other raw materials for mi...

Embodiment 2

[0032] Embodiment 2: the culture material of biogas slurry cultivation Agaricus bisporus, component is as follows, parts by weight:

[0033] 1280 parts of biogas slurry, 500 parts of straw, 400 parts of cow dung powder, 18 parts of superphosphate, 3 parts of urea, 45 parts of lime powder, 9 parts of gypsum powder, and 9 parts of calcium carbonate. The preparation method is as follows:

[0034] 1. The biogas slurry is taken from a biogas digester that produces gas normally and has been in operation for more than three months after a major refueling. The measured pH value is 7±0.5, fully decomposed, dark brown in color, and a layer of brown bubbles is densely covered on the surface of the biogas slurry For biogas slurry, put fresh biogas slurry into the cement pond and allow it to be naturally aerated for 10 days. Then, according to the cultivation formula of Agaricus bisporus, the biogas slurry after aeration is added together with other raw materials for mixing, and the cultu...

Embodiment 3

[0037] Embodiment 3: the culture medium of biogas slurry cultivation Agaricus bisporus, component is as follows, parts by weight:

[0038] 2480 parts of biogas slurry, 800 parts of corn cob, 1000 parts of cow dung powder, 36 parts of superphosphate, 6 parts of urea, 90 parts of lime powder, 18 parts of gypsum powder, and 18 parts of calcium carbonate. The preparation method is as follows:

[0039] 1. The biogas slurry is taken from a biogas digester that produces gas normally and has been in operation for more than three months after major refueling. The measured pH value is 7±0.5, fully decomposed, dark brown in color, and a layer of brown bubbles is densely covered on the surface of the biogas slurry in the biogas digester. For biogas slurry, put the fresh biogas slurry into the aeration tank, use the air compressor to force the air into it, form the air flow and roll and stir for 5 consecutive days, so that the fresh biogas slurry can fully contact with oxygen, dissolve oxy...

Abstract

The invention relates to a method making the use of biogas liquid to cultivate bisporus mushroom, pertaining to the technical field of making the use of new resources to cultivate bisporus mushroom. First in the invention, water liquid for basic cultivation materials in routine method is replaced by the biogas liquid which is next made use of dressing fertilizer to supplement nutrition, and in particular quickly available components consumed during the producing of the mushroom. The basic cultivation materials comprise biogas liquid, forage, cattle manure, calcium superphosphate, urea, lime powder, land plaster and calcium carbonate, wherein, the biogas liquid comprises a plurality of nutrition and plant diseases and insect pests in raw materials can be killed or controlled by anaerobic fermentation during the production of biogas, which realizes reuse of biogas, reduces cost and improves the output of bisporus mushroom for the completion and balance of nutrition in basic cultivation materials to the greatest degree, and is beneficial for the development of recycling economy and environment protection.
