Description

Tea tree mushroom Nutrient medium preparation method

Technical field

The present invention relates to a kind of mushroom Nutrient medium preparation method, exactly disclose a kind of tea tree 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

Tea tree 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:

Growth temperature: 16 DEG C ~ 20 DEG C;

Humidity: 85% ~ 92%;

Nutrient medium component proportion: the auxiliary material 6% ~ 15% such as straw 35% ~ 60%, cotton seed hull 25% ~ 35%, unslaked lime 5% ~ 15%, wheat bran 15% ~ 35%, broken wheat straw 6 ﹪ ~ 10 ﹪, chicken manure, farmyard manure;

Technical process: 1. pulverized by straw as long 1 ~ 2cm threadiness, considers to be worth doing and enters stirrer with the cotton seed hulls after pulverizing and fully mix, add 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 5% ~ 15%, add wheat bran, broken wheat straw and the auxiliary material such as chicken manure, farmyard manure in proportion 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, keeps room temp 16 DEG C ~ 20 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: the auxiliary materials 10% such as straw 37%, cotton seed hull 27%, unslaked lime 5%, wheat bran 15%, broken wheat straw 6%, chicken manure, farmyard manure 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 18 DEG C, humidity is at 85% ~ 92% bacteria growing.
