Problems solved by technology

[0003] The development of biogas is an important development direction of rural new energy construction. The country and localities and farmers attach great importance to it. However, a large amount of biogas residue is either discarded or directly used as fertilizer. The utilization efficiency is not high and the technological content is not high. Therefore, it is urgent It needs to be reused, which not only prolongs the industrial chain, but also makes it profitable, so as to meet the requirements of developing circular economy and building new countryside

preparation example Construction

[0015] The preparation method of the culture medium of biogas residue cultivation Agaricus bisporus, the steps are as follows:

[0016] 1. The biogas residue is obtained by selecting a biogas digester with normal gas production and running for more than three months after a major refueling. The pH of the biogas slurry is 7±0.5. The fully decomposed biogas residue is taken out, and the fresh biogas residue taken out is subjected to aerobic treatment. : Pile it on the hardened ground to drain water and aerate naturally, spread the biogas residue thinly to dry, and remove foreign matter such as large dung lumps, earth and stones at the same time.

[0017] 2. When the biogas residue is aerobically treated to a water content below 65%, add superphosphate, urea, lime powder, raw gypsum powder, and calcium carbonate powder, mix well, and then mix with forage and manure powder to obtain a medium material products.

[0018] When the above biogas residue is taken from a pool with a cap...

Embodiment 1

[0029] Embodiment 1: the culture medium of biogas residue cultivation Agaricus bisporus, component is as follows:

[0030] Biogas residue 2000kg, wheat straw 3000kg, cow dung powder 1000kg, superphosphate 100kg, urea 20kg, lime powder 180kg, gypsum powder 90kg, calcium carbonate powder 60kg. The formula is suitable for producing Agaricus bisporus in a cultivation area of ​​200 to 250 square meters, and the existing techniques for cultivating Agaricus bisporus can be adopted in the application of base material fermentation, sowing and germination, fruiting and the like.

[0031] Preparation method, the steps are as follows:

[0032] The biogas residue is taken from a biogas digester that produces gas normally and has been in operation for more than three months after a major refueling, with a capacity of 100m 3 For the following small and medium-sized biogas digesters, the pH of the biogas slurry is 7±0.5. Take fully decomposed biogas residues, stack the fresh biogas residues ...

Embodiment 2

[0033] Embodiment 2: the culture medium of biogas residue cultivation Agaricus bisporus, component is as follows:

[0034] Biogas residue 2000kg, straw 3000kg, cow dung powder 1000kg, superphosphate 120kg, urea 18kg, lime powder 180kg, gypsum powder 90kg, calcium carbonate powder 50kg. The formula is suitable for producing Agaricus bisporus in a cultivation area of ​​220 to 270 square meters, and the existing techniques for cultivating Agaricus bisporus can be adopted in the application of base material fermentation, sowing and fungus growth, and fruiting.

[0035] Preparation method, with embodiment 1, difference is:

[0036] Biogas residue is taken from a pond with a capacity of 100m 3 For the above-mentioned large and medium-sized biogas digesters, fully dry them so that the moisture content is below 15%, add superphosphate, urea, lime powder, raw gypsum powder, and calcium carbonate, mix well, pack and store them for later use, and mix them with forage for use , Fecal po...

Abstract

A base material for culturing bisporic mushroom from sewage slag consists of forage, sewage slag, manure powder, ordinary superphosphate, urea, lime powder, gypsum powder and lime carbonate powder. It costs low, has more yield and various material sources, it elongates industrial chain and is beneficial for circulation economics.

Description

technical field [0001] The invention relates to a biogas residue utilization method, in particular to a culture medium for cultivating Agaricus bisporus using biogas residue as a raw material of animal feces and a preparation method thereof, and belongs to the technical field of cultivating Agaricus bisporus using new raw material resources. Background technique [0002] Agaricus bisporus belongs to the phylum Fungi, Basidiomycetes, Agaricaceae, Agaricaceae, and the genus Mushroom. Edible fungus is the first in almost all countries engaged in the production of edible fungi, among which my country, the United States, France, Australia, etc. are the most; my country first started production in southern regions such as Fujian and Zhejiang. Production in Henan, Shandong, Hebei and other places has risen rapidly, and industrialized production has been formed. For example, Shenxian County, Shandong Province has been named "the hometown of Agaricus bisporus in China" by relevant depa...
