Abstract

The invention relates to a method (3) for preparing a needle mushroom nutrient medium, which comprises temperature, humidity and composition proportion as well as process flow. The method is characterized in that temperature is 17-22 DEG C, the humidity is 85%-90%, the nutrient medium comprises the following raw materials by proportion: 45-60% of crop straw, 15-25% of small wood chip, 5-8% of gypsum powder, 10-20% of soybean meal, 10-20% of wheat bran and 5-10% of cob. The process flow comprises the following steps: 1)uniformly mixing crop straw, small wood chip and cob in proportion, crushing and stirring, adding 80-90% of water for uniformly stirring, building a pile and then fermenting for 12-15 days; 2)adding the discharged material in 5-8% of gypsum powder and uniformly mixing, then disinfecting; 3)adding soybean meal and wheat bran in proportion for coating and then exposing for 2-3 days; 4)packaging the discharged material and disinfecting at high temperature; 5)filling the discharged material in bags, and then grounding and inoculating strain; and 6) running strain at room temperature of 17-22 DEG C, and growing.

Description

A kind of needle 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 needle 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

A kind of needle mushroom Nutrient medium preparation method, mainly comprises: 1, temperature, and 2, humidity, 3, component proportion, 4, technical process; It is characterized in that:

Temperature: 17 DEG C ~ 22 DEG C;

Humidity: 85% ~ 90%;

Component proportion: crop material 45% ~ 60%, spile 15% ~ 25%, terra alba 5% ~ 8%, dregs of beans 10% ~ 20%, wheat bran 10% ~ 20%, corn cob 5% ~ 10%;

Technical process: 1. by crop material, that spile, corn cob are mixed in proportion crushing, stirring is even, and add 80% ~ 90% water and stir and build heap fermentation 12 ~ 15 days; 2. terra alba flow process 1 discharging being added 5% ~ 8% mixes sterilization; 3. add dregs of beans in proportion and wheat bran overlay film is exposed to the sun 2 ~ 3; 4. by flow process 3 discharging pack high-temperature sterilization; 5. flow process 4 discharging pack is added, inoculation bacterial classification; 6. room temperature 17 DEG C ~ 22 DEG C sends out bacterium, growth.

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: crop material 47%, spile 18%, terra alba 7%, wheat bran 10%, dregs of beans 13%, corn cob 5% mix by (1), the water adding 80% ~ 90% spills leaching and builds heap, then overlay film sealing, be exposed to the sun 12 ~ 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) in Nutrient medium, bacterial classification is inoculated; (4) keep room temp 17 DEG C ~ about 22 DEG C, humidity is in 85% ~ 90% bacterium, added growth.

Claims

1. a needle mushroom Nutrient medium preparation method (3), mainly comprises: temperature, humidity, component proportion and technical process; It is characterized in that: temperature: 17 DEG C ~ 22 DEG C; Humidity: 85% ~ 90%; Component proportion: crop material 45% ~ 60%, spile 15% ~ 25%, terra alba 5% ~ 8%, dregs of beans 10% ~ 20%, wheat bran 10% ~ 20%, corn cob 5% ~ 10%; Technical process: 1. by crop material, that spile, corn cob are mixed in proportion crushing, stirring is even, and add 80% ~ 90% water and stir and build heap fermentation 12 ~ 15 days; 2. terra alba flow process 1 discharging being added 5% ~ 8% mixes sterilization; 3. add dregs of beans in proportion and wheat bran overlay film is exposed to the sun 2 ~ 3; 4. by flow process 3 discharging pack high-temperature sterilization; 5. flow process 4 discharging pack is added, inoculation bacterial classification; 6. room temperature 17 DEG C ~ 22 DEG C sends out bacterium, growth.
