Abstract

The invention relates to a preparation method of an agrocybe cylindracea cultivation material; lentinus edodes stem roots are applied to an agrocybe cylindracea cultivation technology. Compared with the prior art, the preparation method has the advantages that 1, leachate of the lentinus edodes stem roots is a pure natural nutrient solution and contains a wide variety of bioactive substances, and stacking fermentation is carried out by mixing a soak material of the lentinus edodes stem roots and a cultivation material, so that beneficial microorganism propagation is promoted, a microbial flora in the material is improved, and catalytic decomposition of the cultivation material is accelerated; 2, the fermented cultivation material contains high-activity beneficial bacteria and active metabolites of the beneficial bacteria, and thus a promotion effect for the growth of agrocybe cylindracea mycelia is realized, and the mycelia can be vigorous in growing trend and high in antibacterial property; 3, resources such as labor force and coal carbon are reduced, so that the environment pollution is reduced, and the method is in accordance with the idea of low carbon and environment protection.

Description

A kind of making method of agrocybe aegerita culture material

Technical field

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

Background technology

Tea tree mushroom has another name called Agrocybe aegerita (Brig) Sing, chaxingu mushroom, is a kind of rare edible fungus variety.The tender handle of tea tree mushroom lid is crisp, and the pure delicate fragrance of taste, includes 18 seed amino acids, can not synthesize comprising human body voluntarily or transform, and must absorb from food 8 kinds of necessary amino acid, and also containing other many active factor materials, there is good food, pharmaceutical use.

The traditional cultivating method of tea tree mushroom is cured material bag-cultured, and planting material carries out inoculation culture after high pressure or normal-pressure sterilization, and the miscellaneous bacteria now in material is killed, and 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 planting material nutrient loss, causes planting material transformation efficiency 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 tea tree mushroom quality of producing is good, output is high.

The technical solution adopted in the present invention is:

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

(1) prepare burden: cotton seed hulls 28-36%, corn cob 18-22%, wood chip 12-18%, rice bran 15%, tea seed cake powder 10%, mushroom tang 3-4%, lime 2.5%, calcium carbonate 1%, calcium superphosphate 1%, be all the quality of dry-matter, proportioning sum is 100%; Described corn cob is the cob after corn threshing, through drying, being ground into the particle of particle diameter 4mm-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 cotton seed hulls, corn cob, wood chip, tea seed cake powder 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, keep 24h, then carry out turning, and turning every day later once, during first time turning, add lime, calcium carbonate, calcium superphosphate is added during second time turning, rice bran is added, altogether turning 3-4 time, time remaining 5d-6d during last turning, 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, during pack, 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 20 DEG C-22 DEG C, humid control at 60%-75%, through the cultivation of 24d-26d, mycelia covers with pocket, enters management of producing mushroom routinely.

Mushroom tang is applied to the method for tea tree mushroom 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, 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 tea tree mushroom mycelia;

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