Embodiment 1

[0027] 1. Strain treatment

[0028] (1) Selection of mother species: Select the mother fungus with stable species, thick white mycelia, uniform and vigorous mycelium growth, and covered the inclined surface of the test tube;

[0029] (2) Inoculation and cultivation: The transfer of the PDA test tube is carried out in the ultra-clean workbench. Select a strain on the slant of the test tube and operate it next to the flame of the alcohol lamp. placed in an incubator for cultivation;

[0030] (3) Expansion of the original seed: the inoculation of the triangular flask is carried out in an ultra-clean workbench. The liquid stock culture medium contained in the triangular flask is: water 97.8%, soybean meal 0.29%, potassium dihydrogen carbonate 0.10%, magnesium sulfate 0.05%, glucose 1.47%, peptone 0.29%. Select a test tube slant strain, operate it next to the flame of an alcohol lamp, take double-layer newspapers to wrap the mouth of the bottle, stick a label on the triangular fl...

Abstract

The invention discloses a method for industrial cultivation of Pleurotus eryngii by using Pennisetum alopecuroides. The cultivation method comprises the following steps: fungal strain treatment, fungus bag production, fungus bag inoculation, fungus growth management, and harvesting, wherein culture materials for the fungus bag production comprise the following raw material composition in percentage by mass: 3.2% to 13% of bagasse, 3.2% to 9.8% of Pennisetum alopecuroides, 22.2% of sawdust, 19% to 26% of corncob, 18% of bran, 8.8% of corn meal, 9% of soybean meal, 1.8% of light calcium, 1.2% oflime, wherein the total mass percentage of all the components is 100%. In the method, Pennisetum alopecuroides is partially used to replace the bagasse or corn cob in an existing cultivation matrix,and the produced Pleurotus eryngii has a reasonable ratio of carbon to nitrogen in fungus bags, and sufficient nutrients, and can increase the bioconversion rate of the Pleurotus eryngii. Compared with conventional methods, the method has a yield increased by 15% to 20%. Also, the method reduces the production cost and improves the economic benefits. In combination with the production process, thenutritional quality and flavor of Pleurotus eryngii are effectively improved.

Description

technical field [0001] The invention belongs to the field of production methods of pleurotus eryngii, and in particular relates to a method for industrially cultivating pleurotus eryngii by utilizing Pennisetum eryngii. Background technique [0002] The scientific name of Pleurotus eryngii is Pleurotus eryngii. It is a new species of rare edible fungus that integrates edible, medicinal and therapeutic uses. It has extremely high nutritional value. . Pleurotus eryngii is not only an ingredient for cooking delicacies, but also has the functions of lowering blood fat, lowering cholesterol, promoting gastrointestinal digestion, enhancing the body's immunity, and preventing cardiovascular disease, etc., which is very popular among people. [0003] The industrialized cultivation of Pleurotus eryngii emerged from southern Fujian and other places, and has spread all over the country. However, due to factors such as climate and raw materials, there are differences in the industriali...
