Problems solved by technology

In recent years, some large wineries and alcohol factories, such as Mianzhu in Sichuan and Linyi in Shandong, have built a number of large-scale biogas projects using distiller's grains as raw materials while vigorously building and using biogas for users. However, the biogas production At the same time, as a new material, the utilization rate of biogas residue is not high

Embodiment 1

[0030] Embodiment 1: The biogas residue of distiller's grains raw material prepares mushroom soil-covering material, and the components are as follows, all in parts by weight:

[0031] 300 parts of biogas residue, 100 parts of corn stalk powder, 200 parts of plow layer soil, 4 parts of lime powder, 2 parts of gypsum powder, 0.5 part of ternary compound fertilizer with nitrogen, phosphorus and potassium nutrient content of 12%wt respectively.

[0032] 1. Obtaining biogas residues: Distiller's grains raw materials are used to produce biogas in large-scale biogas digesters with normal operation and gas production. The pH value of the biogas slurry is 7. Daily feeding and decomposing biogas residues are discharged every day. The fresh biogas residues are mechanically squeezed to remove part of the water. rate reached 70%.

[0033] 2. Soil treatment: Choose arable land with sandy loamy soil, and only take the 20 cm plow layer above the ground; then dry it and crush it. The diameter...

Abstract

The invention relates to a mushroom cover material prepared by using vinasse biogas residues as materials and a preparation method. Thanks to an organic combination of the biogas residues and common soil material, the common soil particle generates more millipores, the permeability, the hydroscopic property, the moisture retention, the organic matter and other nutrient substance are greatly improved, the mushroom culture yield is steadily increased, and synchronously the reuse of the biogas residues is realized and the original turfy soil resources are protected; the preparation method for the mushroom cover material is especially suitable for preparing mushroom cover material with the biogas residues which is the production of a distillery, an alcohol distillery and a large-scale biogas project using vinasse as materials.

Description

technical field [0001] The invention relates to a biogas residue utilization method, in particular to a mushroom-covered soil material prepared from biogas residue produced by a large-scale biogas project using distiller's grains as a raw material and a preparation method thereof. Background technique [0002] Saprophytic mushroom species such as Agaricus bisporus, Agaricus blazei, Stropharia stropharii, and Straw mushrooms all require soil covering treatment in order to produce mushrooms normally, especially Coprinus comatus has the characteristic of "no mushrooms without covering soil", which shows that covering soil The importance of materials for the production of edible fungi; in addition, most varieties such as oyster mushrooms, shiitake mushrooms, pleurotus eryngii, Bailing mushrooms, enoki mushrooms, ganoderma, etc., can also be covered with soil, and have the actual effects of easy management and high yield after covering the soil. In general cultivation production,...
