Problems solved by technology

However, regarding the problem of pests and diseases and the quality stability of straw mushroom products, the above-mentioned documents have not disclosed, or even not resolved, for example: CN104206177B Paragraph 0041 discloses: In Examples 1, 2 and 3, although there are a small number of mold sticks in the later stage, there is mold, but Mutual infection is not obvious, spreads slowly, and the overall pollution rate is low
Obviously, the phenomenon of fungal infection still inevitably occurs in this method

Embodiment 1

[0036] The cultivation technique of straw mushroom comprises the steps:

[0037] S1: Straw mushroom liquid strain fermentation:

[0038] (1) Test tube inoculation: the straw mushroom strain is inoculated to the test tube slope under the condition of aseptic operation, and the inoculation amount is 10%; the straw mushroom strain in the preferred step (1) is Straw mushroom V99;

[0039] The culture medium of the test tube slant of step (1), the proportioning of each raw material is as follows: potato 20%, sucrose 2%, KH 2 PO 4 0.3%, MgSO 4 0.15%, agar 2.2%, peptone 0.4%;

[0040] (2) Activation culture: ferment and cultivate the mushroom strains inoculated in step (1) at 32°C until the hyphae are overgrown; the medium in the activation includes: 2% sucrose, 0.2% peptone, and 0.2% yeast extract , KH 2 PO 4 0.3%, MgSO 4 0.15%, VB 1 0.01%;

[0041] (3) Cultivate liquid strains: take 10 pieces of 5mm × 5mm mother seed strains from the activated test tube slope, and inocul...

Embodiment 2

[0074] The formula and the clinker cultivation process of a kind of straw mushroom liquid strain in Example 1 are different in that the cultivation bag of the solid strain is adopted.

[0075] Select the formula of corn cob in Table 1: Pleurotus eryngii mushroom residue=1:1, set pH=10, and the calculation method is the same as in Table 1. The size of the cultivation bag is 32.5cm×18.5cm, each bag contains about 0.6kg, and the middle of the cultivation material is punched. What solid kind adopts is the prepared test tube kind, shares 19 test tube kinds. The liquid seed adopts the prepared shake flask liquid strain, and shares 600ml. Six different experiments were set up, each with 10 repetitions. For specific settings, see Table 2-3.

[0076] Table 2-3 Different solid-liquid inoculation and inoculation volume

[0077]

[0078] Note: Each test packs 10 bags, a total of 60 bags.

[0079] Inoculation: Inoculate according to the instructions in Table 3, operate in the inocu...

Abstract

The invention belongs to the technical field of edible fungi cultivation, and particularly relates to a cultivation technology for volvariella volvacea. Excellent strains are mainly selected with bran-contained liquid culture media, high-pressure steam sterilization is carried out, the inoculation amount is 10%, the strains are fixed on a shake bed of 200 r / min and cultivated for 144 h at the temperature of 32 DEG C, liquid strains of the volvariella volvacea are fermented and cultivated, and the liquid strains after cultivation are inoculated into cultivation bags with 100% mushroom dregs andcultivated under the aseptic condition. According to the volvariella-volvacea liquid strain formula and the clinker cultivation technology, high-quality volvariella-volvacea liquid strains are cultivated, wheat bran with the low cost is added into the culture media for cultivating the strains, cultivation is carried out with waste strain dregs, waste is turned into wealth, efficient production isachieved, and the economic cost is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a cultivation technique of straw mushrooms. Background technique [0002] Straw mushroom (Volvariella volvacea) is a saprophytic fungus growing in the tropics and subtropics, belonging to the kingdom Fungi (Fungi), Basidiomycota (Basidiomycota), Agaricomycetes (Agaricales), Agaricales (Agaricales) Pluteaceae), the genus Volvariella. Straw mushroom, also known as orchid mushroom and bract mushroom, originated in southern China. It is an important tropical and subtropical mushroom. It is the third largest cultivated edible fungus in the world. The output of straw mushroom in my country ranks first in the world, mainly distributed in South China. area. Straw mushrooms are not only delicious but also rich in nutritional value. The meat of fresh mushrooms is tender and refreshing; the dried mushrooms are rich in aroma and are treasures of banquets. It ...
