Abstract

The invention discloses a preparation method of a nutritional medium for agaricus bisporus and volvariella volvacea. The preparation method mainly comprises the parameters including temperature, humidity, component ratio and process flows and is characterized in that the component ratio is as follows: 40-50% of rice straws, 15-25% of soybean cake powder, 20-30% of dry cattle manure, 5-10% of lime and 5-15% of auxiliary materials; and the process flows are as follows: 1, smashing the rice straws to be shaped like 1-2cm fibers, sufficiently mixing the smashed rice straws, the soybean cake powder and the dry cattle manure in a stirring machine, and adding 80-90% of water in the mixing process; 2, composting materials discharged in the process flow 1, and fermenting for 10-15 days; 3, carrying out secondary stirring on the fermented materials, adding the lime and 5-15% of the auxiliary materials, and uniformly stirring the materials; 4, bagging the materials discharged in the process flow 3, and sterilizing in a high-temperature boiler; 5 racking the sterilized matrix bags, and carrying out secondary sterilization on the matrix bags; and 6, inoculating strains to the matrix bags treated in the process flow 5, and dispersing the matrix bags on a glade to generate and grow fungi at the temperature of 18-22 DEG C and the humidity of 90-95%.

Description

Bisporous mushroom, straw mushroom Nutrient medium preparation method

Technical field

The present invention relates to the preparation of a kind of mushroom Nutrient medium, exactly disclose a kind of bisporous mushroom, straw mushroom Nutrient medium preparation method.

Background technology

Edible mushrooms is desirable whole food or multifunctional food.Eat in the whole world at present and maximum be commonly referred to as mushroom, formal name used at school is Twospore Mushroom.From wild species, screening domestication fine quality production bacterial classification is had great potentialities further.China once tamed also artificial culture success mushroom, auricularia auriculajudae, golden ear, white fungus, straw mushroom, needle mushroom, Hericium erinaceus (Bull. Ex Fr.) Pers., dictyophora phalloidea etc. in the world first, now tame Tricholoma mongolicum Imai, and wild edible fungus King Boletus, morel, the beautiful mushroom of fragrant apricot, rivet mushroom, suillusbovinus, Russula vinosa etc. also can gather in a large number, supply and marketing is in domestic and international market.Artificial breeding technique the further developing also along with science of edible mushrooms, goes on the road of large-scale production gradually.But because edible mushroom is various in style, growing environment differs widely, particularly require comparatively harsh at the fermentation such as soil property of temperature, humidity, illumination and growth, and the key problem in technology of artificial culture is more the preparation of Nutrient medium.

Summary of the invention

Bisporous mushroom, straw mushroom Nutrient medium preparation method, mainly comprise: 1, temperature, and 2, humidity, 3, Nutrient medium component proportion, 4, technical process; It is characterized in that:

Temperature: 18 DEG C ~ 22 DEG C;

Humidity: 90% ~ 95%;

Nutrient medium component proportion: straw 40% ~ 50%, soybean cake powder 15% ~ 25%, dry cow dung 20% ~ 30%, lime 5% ~ 10%, auxiliary material 5% ~ 15%;

Technical process: 1. straw is pulverized as long 1 ~ 2cm threadiness, enters stirrer and fully mixes, add the water of 80% ~ 90% in mixing process with soybean cake powder, dry cow dung; 2. the discharging of flow process 1 is built heap fermentation 10 ~ 15 days; 3. the material after fermentation is carried out secondary stirring, add lime, 5% ~ 15% auxiliary material simultaneously, stir; 4. the discharging of flow process 3 is entered dress chartered plane dress bag, be placed in exterminating bacterium in high-temperature boiler; 5. the base-material after sterilizing is wrapped frame and is carried out cultivation indoor secondary exterminating bacterium; 6. pair flow process 5 process after base-material bag inoculation bacterial classification, intersperse among woodland public land 18 DEG C ~ 22 DEG C, humidity 90% ~ 95% bacteria growing.

This technological operation is simple, and raw material sources are extensive, and the Nutrient medium of preparation is nutritious, continues the provisions cycle long, is conducive to growing of mushroom, is applicable to large-scale production and application.

Embodiment

Below in conjunction with specific embodiment, specific features of the present invention is described further.

Embodiment: straw 44%, soybean cake powder 23%, dry cow dung 22%, lime 5%, auxiliary material 6% mix by (1), the water adding 80% ~ 90% spills leaching and builds heap, then overlay film sealing, be exposed to the sun 10 ~ 15 days under daylight (spring and summer season), autumn and winter season should in greenhouse heating fermentation; (2) turn after fully fermenting evenly, pack is placed in exterminating bacterium in high-temperature boiler; (3) door and window closed by added bed of filling out, and carries out secondary exterminating bacterium to culturing chamber; (4) in Nutrient medium, bacterial classification is inoculated; (5) keep room temp about 20 DEG C, humidity is at 90% ~ 95% bacteria growing.

Claims

1. bisporous mushroom, straw mushroom Nutrient medium preparation method, mainly comprises: (1) temperature, (2) humidity, (3) Nutrient medium component proportion, (4) technical process; It is characterized in that:

Temperature: 18 DEG C ~ 22 DEG C;

Humidity: 90% ~ 95%;

Technical process: (1). straw is pulverized as long 1 ~ 2cm threadiness, enters stirrer and fully mixes, add the water of 80% ~ 90% in mixing process with soybean cake powder, dry cow dung; (2). the discharging of flow process 1 is built heap fermentation 10 ~ 15 days; (3). the material after fermentation is carried out secondary stirring, adds lime, 5% ~ 15% auxiliary material simultaneously, stir; (4). the discharging of flow process 3 is entered dress chartered plane dress bag, be placed in exterminating bacterium in high-temperature boiler; (5). the base-material after sterilizing is wrapped frame and is carried out cultivation indoor secondary exterminating bacterium; (6). the base-material bag inoculation bacterial classification after processing flow process 5, intersperses among woodland public land 18 DEG C ~ 22 DEG C, humidity 90% ~ 95% bacteria growing.
