Description

Apricot spore 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 apricot spore 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

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

Temperature: 18 DEG C ~ 25 DEG C;

Humidity 85% ~ 92%;

Nutrient medium component proportion: mealy potato 15 ~ 20%, cotton seed hulls 15% ~ 30%, unslaked lime 2% ~ 7%, straw 35% ~ 50%, auxiliary material 5% ~ 15%, wheat bran 10% ~ 15%;

Technical process: 1. pulverized by straw as long 1 ~ 2cm threadiness, entering stirrer with mealy potato and cotton seed hulls (wherein cotton seed hulls pulverizing) fully mixes, and adds the water of 80% ~ 90% in mixing process; 2. the discharging of flow process 1 is built heap fermentation 10 ~ 15 days; 3. the material after fermentation is carried out secondary stirring, and add the unslaked lime of 2% ~ 7%, add 5% ~ 15% auxiliary material and wheat bran 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 pair flow process 5 process, temperature 18 DEG C ~ 25 DEG C, humidity 85% ~ 92% 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: mealy potato 19%, cotton seed hulls 25%, straw 30%, unslaked lime 7%, auxiliary material 7%, wheat bran 12% 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 18 DEG C ~ 25 DEG C, humidity is 85% ~ 92% bacterium, and constant temperature grows.
