Abstract

The invention discloses a preparation method of a tremella cultivation material, which is a technology of applying mushroom stems to tremella cultivation. Compared with the existing technology, the preparation method has the following advantages that firstly, as a pure natural nutrient solution, a mushroom stem leaching solution contains saccharides, amino acids, peptides, nucleic acids and trace elements, as well as diverse biological hormones, and the mushroom stem dregs also contain a great amount of un-leached bioactive substances; therefore, by mixing a mushroom stem soaking material with cultivation raw materials for stacking fermentation, the preparation method can promote the reproduction of beneficial microorganisms, improve microbial flora in the material and accelerate the catalytic decomposition of the cultivation materials; secondly, with high-activity beneficial bacteria and active metabolites, the fermented cultivation material has an effect of promoting the growth of tremella mycelia and cohabitant fungi mycelia, showing vigorous growing trend of the mycelia and strong capacity of resisting hybrid bacteria; and thirdly, the preparation method can save labor, coal and other resources, relieve environmental pollution and meet the concept of low-carbon environmental protection.

Description

A kind of making method of cultivating white fungus material

Technical field

The making method of a kind of cultivating white fungus material of the present invention, is the technology be applied to by mushroom tang in cultivating white fungus, belongs to fungus growing technique field.

Background technology

White fungus has another name called Tremella, tremella, is the food medicine dual-purpose bacterium that China has long enjoyed a good reputation.Record according to Compendium of Material Medica, white fungus slightly sweet flavor, cool in nature, moistening lung enriching yin, reduces phlegm, and promotes the production of body fluid, cough-relieving blood, controls dry consumptive lung disease, convulsive seizure due to phlegm-fire coughs inverse, constipation due to dry stool, and display white fungus has splendid health functions.

The traditional cultivating method of white fungus is grog cultivation, and planting material carries out inoculation culture after high pressure or normal-pressure sterilization, and the contour molecular organic material of the Mierocrystalline cellulose now in material is degraded, miscellaneous bacteria in material is also killed, therefore, when planting material sends out bacterium, mycelial growth is fast, and living contaminants is few.But along with the significantly rise of the price of labour power and fuel price, grog cultivation cost increases severely, and high-temperature sterilization also causes the loss of planting material nutritive substance, causes biological transformation ratio to reduce simultaneously.

Mushroom is famous and precious edible one of the medicinal fungus of holding concurrently in the world, and current China mushroom production accounts for 70% of world's mushroom ultimate production, has the equal mushroom culture in the province of more than 70% in China.Because champignon stems stiffness of foot in children, content of cellulose are higher, palatability is poor, and therefore, mushroom is being eaten raw or in the course of processing, the tang of mushroom can remove as tankage by the producer, causes the mushroom tang accounting for mushroom weight about 30% to become waste.

Summary of the invention

For the deficiencies in the prior art, the present invention adds the immersion of mushroom tang and expects to mix and stir to carry out banking up with planting material to ferment, and do not add sterilant, sterilant during windrow, the planting material after fermentation directly packs inoculation, bacterium bag living contaminants is few, and the white fungus quality of producing is good, output is high.

The technical solution adopted in the present invention is:

A making method for cultivating white fungus material, comprises batching, fermentation, turning, pack, inoculation, sends out bacterium, concrete operation step:

(1) prepare burden: wood chip 46-54%, cotton seed hulls 20-28%, wheat bran 20%, mushroom tang 4-5%, gypsum 1.5%, be all the quality of dry-matter, proportioning sum is 100%; Described wood chip is the deciduous tree weed tree sawdust of particle diameter 3mm-5mm; Described mushroom tang is the tankage in the Lentnus edodes course of processing, is ground into the particle of 2mm-3mm after drying;

(2) ferment: mushroom tang particle is added clear water by 20-30 weight ratio doubly, soak 18h-24h at normal temperatures, then leach liquor is admixed in wood chip, cotton seed hulls compound uniformly together with champignon stems slag, stockpile is become high 1.0m-1.2m, wide 2m-3m, the trapezoidal heap that length is not limit, the culture material often piled controls at dry weight 300kg-500kg, after carrying out heap, surrounding is patted, on heap, insert some vertical pores with the wooden stick of diameter 10cm-15cm again, at the bottom of straight through reactor, stomatal frequency is 1/m ³, finally cover straw mat by its spontaneous fermentation;

(3) turning: after material temperature reaches 60 DEG C, keeps 24h, then carries out turning, and turning every day later once, add gypsum during first time turning, add wheat bran during second time turning, altogether turning 3-4 time, time remaining 5d-6d, when stopping fermentation, the water content of planting material is 63%-65%;

(4) pack, inoculate, send out bacterium: the planting material fermented is after heat radiation, adopt the polyethylene cylinder sacked material of folding length 15cm, length 60cm, thick 0.04mm, when filling with substance puts into bacterial classification at two ends of bag, at equidistant dislocation access 5 cave, the both sides of bag bacterial classification after charging, after inoculation, cultivating bag is emitted in dark bacteria room, temperature controls at 20 DEG C-22 DEG C, humid control is at 60%-75%, through the cultivation of 38d-40d, mycelia covers with pocket, just enters out syrinx reason.

Mushroom tang is applied to the method for cultivating white fungus by the present invention, and apart from outside explanation, other operation steps is all undertaken by this area routine techniques.

The present invention's advantage is compared with prior art:

1. mushroom tang leach liquor is full-natural nutritive liquid, containing glucide, amino acid, peptide class, nucleic acid and trace element, bio-hormone also containing abundant species, also the biologically active substance do not leached in a large number is had in champignon stems slag, add and expect to mix and stir to carry out banking up with culturing raw material to ferment with the immersion of mushroom tang, promote beneficial microorganism breeding, improve the microorganism species in material, accelerate the catalytic decomposition of planting material;

2. the planting material after fermentation has high reactivity probiotics and active metabolite thereof, has accelerating effect, show as prosperous, the anti-miscellaneous bacteria ability of mycelium growth vigor strong to the growth of white fungus mycelia and incense ashes mycelia;

3. save the resource such as manpower, coal, decrease environmental pollution, meet low-carbon environment-friendly theory.
