Problems solved by technology

[0005] Pleurotus eryngii cottonseed hulls and sawdust strains: cottonseed hulls or wood chips are used as raw materials, and some auxiliary ingredients are added. It is the most commonly used seed production method in production. The main problems of this technology are: first, due to the 1. The nutrition of sawdust is not enough, the vitality of Pleurotus eryngii mycelia is weak, and the mycelia often have problems such as poor germination after inoculation, slow growth, and weak resistance; It takes a lot of work and effort to smash it into particles of a certain size, and it is difficult to meet the requirements of uniform particles. After inoculation, the germination is uneven, resulting in irregular mycelial growth. Therefore, the qual...

Embodiment 1

[0021] The steps of producing Pleurotus eryngii bacterial classification are as follows:

[0022] (1) Treatment of wheat grains: Soak the wheat grains in water at 20°C for 12-16 hours to make the grains absorb enough water. After absorbing the water, pour the wheat grains into boiling water at 100°C and cook for 5 minutes until the center of the wheat grains has no dry core, and then spread to cool. spare;

[0023] (2) Culture medium preparation: according to the weight of dry material, weigh 100 parts of wheat grains, 20 parts of wheat bran, and 1 part of gypsum powder in a container, and stir evenly;

[0024] (3) branch processing: select the maple wood to split and grow 12cm, 3 * 4mm thick small wooden stick, soak more than 10 hours in 1% (wt%) lime water, make branch absorb enough water;

[0025] (4) Bottling: first branch is inserted in glass bottle or plastic bottle, according to branch / grain=1 / 1.1 (ratio by weight), add the wheat grain culture medium that has deplo...

Embodiment 2

[0031] The steps of producing Pleurotus eryngii bacterial classification are as follows:

[0032] (1) Treatment of wheat grains: Soak the wheat grains in water at 15°C for 16 hours to make the grains absorb enough water. After absorbing the water, pour the wheat grains into boiling water at 100°C and cook for 5 minutes until the center of the wheat grains has no dry core, then spread to cool and set aside;

[0033] (2) Culture medium preparation: according to the weight of dry material, weigh 50 parts of wheat grains, 10 parts of wheat bran, and 0.5 parts of gypsum powder in the container, and stir evenly;

[0034] (3) branch processing: select European and American poplar trees to split and grow 20cm, 2 * 7mm thick little wooden stick, soak 20 hours in 2% (wt%) lime water, make branch absorb enough water;

[0035] (4) Bottling: first branch is inserted in glass bottle or plastic bottle, according to branch / grain=1 / 1.1 (ratio by weight), add the wheat grain culture medium ...

Embodiment 3

[0041] The steps of producing Pleurotus eryngii bacterial classification are as follows:

[0042] (1) Treatment of wheat grains: Soak the wheat grains in water at 25°C for 16 hours to make the grains absorb enough water. After absorbing the water, pour the wheat grains into boiling water at 100°C and cook for 8 minutes until the center of the wheat grains has no dry core, then spread to cool and set aside;

[0043] (2) Medium preparation: according to the weight of dry material, weigh 150 parts of wheat grains, 30 parts of wheat bran, and 2 parts of gypsum powder in the container, and stir evenly;

[0044] (3) branch processing: select European and American poplar trees to split and grow 10cm, 3 * 7mm thick small wooden stick, soak 10 hours in 1% (wt%) lime water, make branch absorb enough water;

[0045] (4) Bottling: first branch is inserted in glass bottle or plastic bottle, according to branch / grain=1 / 1.1 (ratio by weight), add the wheat grain culture medium that has d...

Abstract

The invention discloses a method for producing pleurotus eryngii quel strains. The method comprises wheat grain treatment, branch treatment, blending of a culture medium, bottling, sterilization, inoculation, strain culture and the like. By the method, the time that hyphae are fully grown in culture bags is shortened, the fungus ages of the culture bags are consistent, the yield is improved, and the production period is shortened by over 30 days, namely shortened from original 75 days to 45 days; and the method is an effective alternative technology for the conventional methods for producing the pleurotus eryngii quel strains.

Description

technical field [0001] The invention relates to the technical field of edible fungus production, in particular to a method for producing Pleurotus eryngii strains by a binary method. Background technique [0002] Pleurotus eryngii Quel is rich in nutrients, contains high protein, a variety of amino acids, and is delicious. It has certain health care functions and is very popular with people. [0003] The production of Pleurotus eryngii originated in Europe, and my country introduced it from Japan in 1990', and it was widely cultivated all over the country soon, and has now developed into the second largest edible fungus species produced in my country's factory. Pleurotus eryngii strains are obtained by mycelium vegetative propagation method, which is cultivated by inoculating the original mycelium in a suitable culture medium. The high-quality Pleurotus eryngii strain mycelium is white, strong and dense. It has strong vitality, the hyphae in the base are white to light yel...
