Abstract

The invention provides a preparation method of an auricularia polytricha cultivation material and relates to a technique of applying lentinus edodes stems to auricularia polytricha cultivation. Compared with the prior art, the preparation method has the following advantages: firstly, a lentinus edodes stem extract is a purely natural nutrient solution and contains rich types of biological active substances; the lentinus edodes stem soaked materials and cultivation raw materials are blended and composted for fermentation, and then the reproduction of beneficial microorganisms is promoted, the microbial flora in the material is improved and the catalytic decomposition of the cultivation material is accelerated; secondly, the fermented cultivation material contains high-activity beneficial bacteria and active metabolites thereof and has a promoting effect on the growth of auricularia polytricha mycelia, and therefore, the mycelia grow vigorously and are high in infectious microbe resisting ability; thirdly, the resources such as manpower and coal can be saved, and the environmental pollution is reduced to conform to the low-carbon environment protection idea.

Description

A kind of making method of auricularia polytricha cultivation material

Technical field

The making method of a kind of auricularia polytricha cultivation material of the present invention, is mushroom tang is applied to the technology in Auricularia polytricha (Mout) Sacc. cultivation, belongs to fungus growing technique field.

Background technology

Auricularia polytricha (Mout) Sacc. quality is tender and crisp, and containing higher carbohydrate, protein, multivitamin and each seed amino acid, nutritious, delicious flavour, is called as " umbrella of jellyfish on tree ".

The traditional cultivating method of Auricularia polytricha (Mout) Sacc. is grog cultivation, and planting material carries out inoculation culture after high pressure or normal-pressure sterilization, and now in material, the macromolecule organic such as Mierocrystalline cellulose has been 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's mushroom tang soaks expects to mix and stir to carry out banking up with culturing raw material to ferment, and do not add sterilant, sterilant during windrow, the planting material after fermentation directly packs inoculation, planting material living contaminants is few, and the Auricularia polytricha (Mout) Sacc. quality of producing is good, output is high.

The technical solution adopted in the present invention is:

A making method for auricularia polytricha cultivation material, comprises batching, fermentation, turning, pack, inoculation, sends out bacterium, concrete operation step:

(1) prepare burden: wood chip 58-62%, bagasse 18-22%, soya-bean cake 12-14%, mushroom tang 3-4%, lime 2.5%, gypsum 1%, 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 bagasse powder is broken into the particle 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, bagasse, soya-bean cake compound together with champignon stems slag uniformly, 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 lime during first time turning, add gypsum 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 vinyon sacked material of 15cm × 60cm × 0.004cm, when filling with substance puts into bacterial classification at two ends of bag, access 3 cave bacterial classifications respectively in the both sides of bag after charging, then cultivating bag is emitted in dark bacteria room, temperature controls at 18 DEG C-20 DEG C, humid control is at 60%-75%, through the cultivation of 36d-38d, mycelia covers with pocket, namely enters grand style, goes out syrinx reason.

Mushroom tang is applied to the method for Auricularia polytricha (Mout) Sacc. cultivation 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, soak with mushroom tang and expect to mix and stir to carry out banking up with culturing raw material to ferment, 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 Auricularia polytricha (Mout) Sacc. mycelia;

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