Embodiment 1

[0027] A method for preparing solid strains of edible fungi is carried out according to the following steps:

[0028] (1) Raw material preparation: prepare sufficient raw materials according to the production volume, and sieve the peat soil to remove debris with a diameter greater than 1cm. It is required that the bran is fresh and free of mildew, and the cottonseed hulls are not agglomerated into agglomerates;

[0029] (2) Preparation: Mix peat soil, cottonseed hulls, bran, gypsum and sucrose according to the components of the medium and their weight ratios, and add water. The weight ratio of raw materials to water is 1:1.2 to 1:1.3 After adding water, the raw materials are mixed and stirred to make the raw materials absorb water evenly, and lime is added to adjust the pH value at the same time, so that the pH value of the prepared medium is 7.0;

[0030] (3) Subpackage: Subpackage the culture medium prepared above with a strain bag, each bag of culture medium is 0.25kg, and ...

Embodiment 2

[0035] A method for preparing solid strains of edible fungi is carried out according to the following steps:

[0036] (1) Raw material preparation: prepare sufficient raw materials according to the production volume, and sieve the peat soil to remove debris with a diameter greater than 1cm. It is required that the bran is fresh and free of mildew, and the cottonseed hulls are not agglomerated into agglomerates;

[0037] (2) Preparation: Mix peat soil, cottonseed hulls, bran, gypsum and sucrose according to the components of the medium and their weight ratios, and add water. The weight ratio of raw materials to water is 1:1.2 to 1:1.3 After adding water, the raw materials are mixed and stirred to make the raw materials absorb water evenly, and at the same time, lime is added to adjust the pH value, so that the pH value of the prepared medium is 6.8;

[0038] (3) Subpackage: Subpackage the culture medium prepared above with a strain bag, each bag of culture medium is 0.25kg, and...

Embodiment 3

[0043] A method for preparing solid strains of edible fungi is carried out according to the following steps:

[0044] (1) Raw material preparation: prepare sufficient raw materials according to the production volume, and sieve the peat soil to remove debris with a diameter greater than 1cm. It is required that the bran is fresh and free of mildew, and the cottonseed hulls are not agglomerated into agglomerates;

[0045] (2) Preparation: Mix peat soil, cottonseed hulls, bran, gypsum and sucrose according to the components of the medium and their weight ratios, and add water. The weight ratio of raw materials to water is 1:1.2 to 1:1.3 After adding water, the raw materials are mixed and stirred to make the raw materials absorb water evenly, and at the same time, lime is added to adjust the pH value, so that the pH value of the prepared medium is 6.5;

[0046] (3) Subpackage: Subpackage the culture medium prepared above with a strain bag, each bag of culture medium is 0.25kg, and t...

Abstract

The invention discloses a preparation method for solid spawn of an edible fungus. The preparation method comprises the following steps: preparing peat soil, cottonseed hulls, bran, gypsum and saccharose according to a formula proportion, adding lime and water, mixing to prepare a culture medium with a proper pH value; and performing high-temperature sterilization, cooling, inoculating mother stains or stock, culturing hypha, clearing dirt to remove impurities in sequence, thereby preparing the solid spawn. The preparation method is simple in preparation process, is low in sterilization requirement, and saves cost better.

Description

technical field [0001] The invention relates to a method for preparing solid strains of edible fungi, which is particularly suitable for culturing the strains of grass-rot edible fungi. Background technique [0002] Grass-rot edible fungi include mushrooms such as Agaricus bisporus, Brazil mushrooms, straw mushrooms, Coprinus comatus, and brown mushrooms. For a long time, grass-rot edible fungi have mostly used solid particles such as wheat grains and grains as the strain medium, and the produced strains for production and cultivation are called wheat grain strains, although wheat grain strains have fast germination , many growth points and strong growth potential, etc., but its production process is cumbersome, labor-intensive and time-consuming, the sterilization requirements are high, and the strain pollution is difficult to control. The storage period is short, generally 35 to 45 days. Contents of the invention [0003] The purpose of the present invention is to over...
