Problems solved by technology

Most of the existing technologies use forage as the main material, which is limited by resources and other conditions.
[0003] In recent years, rural biogas has made great progress. While producing biogas, it also produces a large amount of biogas slurry. Some of the biogas slurry is directly thrown into the farmland, and most of it is discarded, causing secondary pollution. It has not been fully utilized. To a certain extent, it has been in vain waste of good resources

Embodiment 1

[0029] Biogas slurry cultivation culture material of Coprinus comatus, raw material components are as follows, parts by weight:

[0030] 150 parts of biogas slurry, 100 parts of wheat straw, 12 parts of superphosphate, 2 parts of urea, 4 parts of lime powder, and 1.5 parts of gypsum powder.

[0031] A method for cultivating Coprinus comatus by using biogas slurry, comprising base material preparation, base material fermentation, seeding, germination, soil covering, and mushroom output. in,

[0032] 1. Base material preparation, the steps are as follows:

[0033] 1. The fresh biogas slurry is taken from a biogas digester with normal gas production and running for more than three months after a major refueling, with a pH value of 7, fully decomposed, dark brown in color, and a layer of brown bubbles on the surface. The solution was put into the cement pool and aerated naturally for 20 days at a temperature of 5°C.

[0034] 2. Dilute the biogas slurry after natural aeration in...

Embodiment 2

[0042] Embodiment 2: A method for cultivating Coprinus comatus by using biogas slurry, including base material preparation, base material fermentation, sowing, germination, soil covering, and mushroom production. in,

[0043] 1. Base material preparation, the steps are as follows:

[0044] 1. The fresh biogas slurry is taken from a biogas digester with normal gas production and running for more than three months after a major refueling, with a pH value of 7.5, fully decomposed, dark brown in color, and a dense layer of brown bubbles on the surface; fresh biogas Put the liquid into the cement pool, and naturally aerate it for 2 days at a temperature of 36°C;

[0045] 2. Dilute the fresh biogas slurry after natural aeration in step 1 with water in a ratio of 1:1 by volume to obtain the raw biogas slurry, and then,

[0046] 3. Mix 3,000 parts of raw biogas slurry obtained in step 2 with 2,000 parts of rice straw, 40 parts of superphosphate, 6 parts of urea, 80 parts of lime pow...

Embodiment 3

[0053] Embodiment 3: A method for cultivating Coprinus comatus by using biogas slurry, including base material preparation, base material fermentation, sowing, germination, soil covering, and fruiting. in,

[0054] 1. Base material preparation, the steps are as follows:

[0055] 1. The biogas slurry is taken from a biogas digester with normal gas production and running for more than three months after a major refueling, with a pH value of 7.3, fully decomposed, dark brown in color, and a dense layer of brown bubbles on the surface; the fresh biogas slurry Put it into the aeration tank, use the air compressor to introduce air, form an air flow and stir for 3 days, so that the fresh biogas slurry can fully dissolve oxygen and reach the normal oxygen content;

[0056] 2. The fresh biogas slurry after fully dissolved oxygen in step 1 is diluted with water at a volume ratio of 1:1 to become the raw biogas slurry, and then,

[0057] 3. Mix 3,000 parts of raw biogas slurry obtained...

Abstract

The invention relates to a method for planting Goprinus comatus by adopting fen liquid. The main material of cultivating base material is fen liquid and straw and after aerobic treatment, the fresh fen liquid is mixed with water according to volume ration of 1:1. The invention replaces water in mixture and normal earth covering water with fen liquid to water the soil and also applies the fen liquid as additional fertilizer; the fen liquid contains a plurality of nutrient substances, which can rich and balance nutrition in base material, thus reducing the planting cost by about 30 percent, therefore, the invention not only recycles the fen liquid and prolongs circular application chain of biomass energy, but also realizes the full and balanced nutrition of the base material of Goprinus comatus and improves the quality of Goprinus comatus by about 20 percent.

Description

technical field [0001] The invention relates to a method for utilizing biogas slurry, in particular to a method for cultivating Coprinus comatus with biogas by-product biogas slurry, and belongs to the technical field of cultivating Coprinus comatus using new resources. Background technique [0002] Coprinus comatus is cultivated, and traditional method is mostly with crop stalk raw material such as cottonseed husk, corncob, wheat straw, rice straw etc. add water, after fermentation as cultivation base material, CN1189288 disclosed on August 5th, 1998 has introduced a kind of improved Agaricus bisporus and The method for cultivating Coprinus comatus uses softened wheat stalks, corn stalks, mixed fermentation with livestock and poultry, and decomposes to form a cultivation base material. CN1903000 published on January 31, 2007 relates to a method for cultivating Coprinus comatus with dry straw. The dry straw is soaked in lime water, mixed with dry beef powder, urea and phosph...
