Abstract

The invention provides a grifola frondosa cultivation material making method, wherein the cultivation material is characterized by being made from sugarcane residue, sawdust and soybean meal as main raw materials with addition of a lentinus edodes stem base soaked material for performing stacking fermentation. The making method includes steps of material preparation, fermentation, stack turning, packaging with bags, inoculation and spawn running. Biological efficiency of the method reaches 106.5%. The making method is advantaged in that: (1) the lentinus edodes stem base leachate is a pure-natural nutrition liquid containing carbohydrates, amino acids, peptides, nucleic acids and microelements and also contains abundant bio-hormones, and lentinus edodes stem residue also contains a large amount of bio-active substances not being leached, so that by blending the lentinus edodes stem base soaked material and the cultivation raw materials for performing the stacking fermentation, the cultivation material is accelerated in catalytic decomposition; (2) the fermented cultivation material has high-active beneficial bacteria and active metabolites thereof, so that the cultivation material has a promoting effect on growth of mycelia of grifola frondosa and the mycelia is good in growth and is strong in foreign-bacteria-resistant capability; and (3) the making method saves labor intensity and coal and such resources, can reduce environment pollution and satisfies a low-carbon environmental-protective concept.

Description

A kind of making method of Grifola frondosa culture material

Technical field

The making method of a kind of Grifola frondosa culture material of the present invention, is mushroom tang is applied to the technology in Grifola frondosa cultivation, belongs to fungus growing technique field.

Background technology

Grifola frondosa has another name called chestnut mushroom, polyporus frondosus, lotus flower bacterium etc., a kind of food of preciousness, medicinal fungus, the lotus flower that its sporophore likeness in form is in full bloom, fan-shaped cap is layer after layer, fresh and tender sporophore aromatic flavour, be rich in amino acid, polysaccharide and biologically active substance, there is the effect strengthening body immunity, prevention of various diseases.In recent years, as a kind of high-class healthy food, being in fashion the market such as Japan, Singapore, is one of main cultivated edible fungi kind of wideling popularize of the World Food Programme.

The cultivating method that Grifola frondosa is traditional 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 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 Grifola frondosa quality of producing is good, output is high.

The technical solution adopted in the present invention is:

A making method for Grifola frondosa culture material, comprises batching, fermentation, turning, pack, inoculation, sends out bacterium, concrete operation step:

(1) prepare burden: bagasse 37-45%, wood chip 36-44%, soya-bean cake 10-12%, mushroom tang 3-4%, lime 3-4%, gypsum 1%, be all the quality of dry-matter, proportioning sum is 100%; Described bagasse powder is broken into the particle of particle diameter 3mm-5mm; 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 bagasse, wood chip, 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, load the polypropylene plastics pocket of 17cm × 35cm × 0.004cm, stamp and plant bacterium hole, and bag two ends and plant in bacterium hole and put into bacterial classification, 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 22-23d, mycelia covers with pocket, enters management of producing mushroom routinely.

Mushroom tang is applied to the method for Grifola frondosa 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 Grifola frondosa mycelia;

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