Problems solved by technology

On the other hand, when straw produces biogas, it also produces a large amount of biogas residue. The biogas residue is either directly thrown into the farmland or discarded, and the utilization efficiency is not high. In order to meet the requirements of developing circular economy and building new countryside? We treat biogas residues as raw materials for Coprinus comatus cultivation, which can achieve ideal results. This not only conforms to the policy of new energy and new material development and utilization, but also adapts to the direction of comprehensive utilization of rural biomass resources.

preparation example Construction

[0011] A preparation method of a culture medium for cultivating Coprinus comatus with biogas slag as a straw raw material, the steps are as follows:

[0012] 1. Obtaining biogas residue: choose a straw raw material biogas digester with normal gas production, new biogas digester feeding or a large refueling operation for about three months. The pH value of the biogas slurry is 7±0.5. Take fully decomposed biogas The method of aerobic treatment of fresh biogas residues is as follows: pile fresh biogas residues on the hardened ground to drain naturally, and then spread the biogas residues thinly to dry, air-dry or dry them. When the moisture content is below 15%, they can be stored for later use.

[0013] 2. Add the above biogas residue into forage, lime powder, gypsum powder, superphosphate, and urea according to the composition ratio, and mix well to obtain the culture medium for cultivating Coprinus comatus.

[0014] When the above culture material is in use, it is necessary t...

Embodiment 1

[0024] Embodiment 1: the substratum material of biogas residue cultivation Coprinus comatus, component is as follows, parts by weight:

[0025] 300 parts of biogas residue, 9 parts of lime powder, 3 parts of gypsum powder, 6 parts of superphosphate, and 0.9 part of urea.

[0026] In the application, the existing technology can be used for base material fermentation, sowing and germination, and mushroom fruiting management.

[0027] Preparation method, the steps are as follows:

[0028] (1) Biogas residues are taken from straw raw material biogas digesters with normal gas production and operation for more than three months after major refueling. The pH value of biogas slurry is 7±0.5. Fully decomposed biogas residues are taken, and fresh biogas residues are stacked on hardened ground Naturally drain, aerate, and carry out aerobic treatment, then dilute the biogas residue to dry in the sun, air-dry or dry until the moisture content is below 15%, and store it for later use;

Embodiment 2

[0031] Embodiment 2: the substratum material of biogas residue cultivation Coprinus comatus, component is as follows, parts by weight:

[0032] 500 parts of biogas residue, 200 parts of cottonseed hulls, 21 parts of lime powder, 7 parts of gypsum powder, 14 parts of superphosphate, and 2.1 parts of urea. In the application, the prior art of cultivating Coprinus comatus can be adopted for base material fermentation, seeding and fungus generation, fruiting and the like.

[0033] Preparation method, the steps are as follows:

[0034] (1) the preparation of biogas residue is with embodiment 1,

[0035] (2) Mix the biogas residue obtained in step (1) with cottonseed hulls, lime powder, gypsum powder, superphosphate, and urea auxiliary materials according to the formula, and mix well to obtain the culture medium.

[0036] Water is added when the above-mentioned culture material is stacked and fermented, and the weight ratio of material to water is 1:1.6. The fermented culture med...

Abstract

The invention relates to basic cultivation materials and preparation method thereof for making the use of biogas residue with straw as raw material for cultivating coprinus comatus. The biogas residue with straw as raw material is naturally dried first to lead the water content below 15 percent; therefore, the biogas residue as the main material for cultivating coprinus comatus is easy for storage. Then forage, lime powder, land plaster, calcium superphosphate and urea, etc. are added to the biogas residue. The invention broadens the sources of raw materials for cultivating coprinus comatus, realizes the reuse of biogas residue to the greatest extend, reduces about 40 percent of cultivation cost, improves about 10 percent of output and is beneficial for the development of recycling economy and environment protection.

Description

technical field [0001] The invention relates to a biogas residue utilization method, in particular to a culture medium for cultivating Coprinus comatus with biogas residue as a raw material of straw, and belongs to the technical field of cultivating Coprinus comatus using new raw material resources. Background technique [0002] Coprinus comatus, in taxonomy, belongs to the Phylum Fungi, Phylomycetes, Coprinus, and Coprinus. It is named for its shape like chicken legs and meat like chicken shreds. It is a typical saprophytic fungus. Traditional Coprinus comatus cultivation mostly uses crop stalks and agricultural by-products as cultivation materials, such as cottonseed husks, corn cobs, soybean stalks, cotton stalk powder, peanut shells, straw, wheat straw, corn stalks, etc. as the main raw materials. On the one hand, With the emergence of energy problems, as a biomass resource, crop straw has more and more utilization channels, and its utilization value is also increasing. ...
