Abstract

The invention discloses a preparation method of a mushroom culture material, and the main raw materials comprise wood chips, cotton seed hulls, wheat bran, corn cobs and weeds. Bran, rice bran, soybean meal, corn powder, and urea which are rich in organic nitrogen and vitamins and gypsum, calcium carbonate and other inorganic substances are appropriately matched as excipients, and glucose and other soluble sugars can also be added, therefore, the mushroom culture material is prepared. The preparation method aims at obtaining the raw materials locally, saving the cost and simplifying the method.

Description

A kind of preparation method of champignon compost

Technical field

The present invention relates to a kind of mushroom cultivation field, particularly a kind of preparation method of champignon compost.

Background technology

The Lentinus wood-decay fungi.The traditional cultivating method of China is that employing is segment wood cultivated, because of being subjected to the restriction of trees supply and transportation, can only be developed in the abundant area of the forest reserves, and output can not satisfy needs of society far away.

Summary of the invention

The present invention adopts wood chip, cotton seed hulls, wheat bran, corn cob, weeds, do cultivation major ingredient, suitably being equipped with the wheat bran, rice bran, soya-bean cake, Semen Maydis powder, urea and the gypsum that are rich in organonitrogen and VITAMIN, lime carbonate and so on inorganic salt material again is auxiliary material, and add soluble saccharide such as glucose, be made into champignon compost.

Embodiment

Composition of raw materials weight ratio of the present invention is: wood chip 62%, wheat bran 15%, cotton seed hulls 20%, gypsum, lime each 1%.Glucose 1%.

(1) technical process

Prescription---batching---packed---sterilization---cooling---inoculation---taking off bag---grand style

(2) preparation of culture material elder generation with 2～3 purpose sieve, rejects hard thing to wood chip.After with addings such as wheat bran, gypsum, pile the mountain shape, first dry mixing three times; Again with water-soluble urea, sugar, calcium superphosphate etc. water-soluble after, add culture material, mix repeatedly.Water content is controlled at the hand-tight culture material of holding, and has water mark (about water content 60%) to be advisable between webs.Fine high-temperature water wants more on the high side; After culture material is mixed thoroughly, stack a moment, treat that the raw material suction packs after soft slightly again.PH value about 6 is advisable.

(3) the polyethylene cultivating bag is selected in packed, sterilization for use, and elasticity does not have soft sense with the bag central authorities that hand rest installs during pack, and the pocket two ends are not sagging, and raw material will have been adorned in 4～6 hours in order to spend, and goes up the pot sterilization immediately, prevents the souring of fermenting.

The sterilization principle is " tap holder, protect in the middle of tail, the control ", promptly makes a pot middle and lower part temperature rise to 100 ℃ in 3～4 hours, keeps then 10～12 hours, and when finishing soon, the big fire onslaught is a burst of, and stewing again for some time takes the dish out of the pot.Transport cooling room or transfer room after the cooling to, dry the moisture on pocket surface, treat to inoculate when bag interior temperature decline reaches 28 ℃.

(4) inoculation, cultivate inoculation and be chosen in the low temperature time (preferably night) and finish fast, it is fast that action is wanted, and finished in 3～4 hours for 1000 bags.3～5 people 1 group during inoculation, and 1 people removes bag and is discharged on the operator's console, and 1 people wipes alcohol and uses taper bastinade cave (3 cave/bag) in inoculation place, and 1 people breaks bacterial classification off with the fingers and thumb the growth taper and inserts (bacterial classification exceeds pocket) in the cave fast, and sticks on a piece of adhesive tape.Cultivate on the spot after the inoculation, reduce pollution probability, put, pile high apparent temperature situation and decide with " # " font.Row bag finishes 3～4 hours hydrofuges of rear venting, and regulating and controlling temperature is between 22～25 ℃, does not move the bacterium bag in 10 days, promotes mycelia field planting and growth fast.When inoculating mouthful mycelia length, carry out casting, prick the hole simultaneously to 2 centimetres; Grow to 4 centimetres, cover with and carried out the 2nd, 3 time casting at 1/2 o'clock respectively, isolate if having to pollute in time.The mycelia purseful is pricked the hole one time in the time of 10 days again, and hole depth is advisable with bacterium bag radius.

(5) take off bag, grand style bacterium bag is sent out bacterium and is nourished and grown in the time of 40～50 days and peak, the mycelia amount of accumulateing is abundant, can enter reproductive phase, at this moment giving light scattering cultivated 10 ~ 20 days again, total incubation time reaches 50 ~ 70 days, form mycoderm between pocket gradually, then swell knob and begin to secrete the tawny pigment, at this moment mycelia is mature on the whole.When reaching 50%, just can take off the protuberance knob bag, grand style.

Claims (2)

1, a kind of preparation method of champignon compost is characterized in that it is made up of wood chip, cotton seed hulls, wheat bran, corn cob, weeds.And suitably to be equipped with the wheat bran, rice bran, soya-bean cake, Semen Maydis powder, urea and the gypsum that are rich in organonitrogen and VITAMIN, lime carbonate and so on inorganic salt material be auxiliary material.

2, according to claims 1 described formula material formulation weight ratio be: wood chip 62%, wheat bran 15%, cotton seed hulls 20%, gypsum 1%, lime 1%.Glucose 1%.
