CN103070008A - Novel pure-long-straw cultivation edible fungus technology - Google Patents

Abstract

The invention relates to a novel pure-long-straw cultivation edible fungus technology, which is characterized in that straws such as rice straws and wheat straws are used for cultivating the edible fungus without being cut (pulverized); the straws are fermented by utilizing effective microorganism beneficial bacterial strain, so that the substrate base stock is high-efficiently softened, and the decomposition and utilization by the hypha can be favored; nutritional soil is used for being made into a heat insulation layer, so not only is the yearly production realized, but also clean water and nutritive liquid stored in the heat insulation layer can be slowly conveyed to bacteria sticks during the later management, and the yield can be guaranteed; large-sized plastic bags are used as bacteria stick bags, so that the cultivation efficiency is multiplied in production compared with that of an ordinary plastic bag; and liquid strain is used for inoculation, and the liquid strain is flow, so that the liquid strain can be permeated and spread into the straws after the inoculation, once the strain is sprouted, all strain can eat and grow fully, dyeing of infectious microbe can be avoided, and rapidness for the growth of mushrooms can be realized.

Description

A kind of pure long straw cultivation edible mushroom new technology

Technical field

The present invention relates to the cultivation method of a kind of edible mushroom, specifically a kind of pure long straw cultivation edible mushroom new technology.

Background technology

The used raw material of culturing edible fungus mostly is greatly the more rich stalk of rural resource at present, as: straw, wheat straw, sugarcane top, maize leaves and all kinds of weeds etc., employed as above raw material all must can use after processing such as pulverizing or prescind, after processing like this, not only labour intensity has improved, and production cost has also increased thus.Number of patent application is: the technical matters that 200510018508.5 edible mushroom three-dimensional cultivation technique using long straw provides does not need straw is pulverized, but the supporting mould that special use is arranged of this arts demand, complex manufacturing; What this technique was used is solid spawn, needs a month right and left can cover with bacterium after the inoculation, and the production cycle is long, and pollution rate is high; Mycelia must discharge a large amount of heats when sprouting, so this technique can not be produced at high temperature season period.

Summary of the invention

The object of the invention is to overcome the weak point of above-mentioned background technology, and a kind of pure long straw cultivation edible mushroom new technology is provided.

In order to achieve the above object, the solution of the present invention's employing is:

A kind of pure long straw cultivation edible mushroom new technology, its processing step is as follows:

(1) select materials: the stalk thing that choosing parches, nothing is gone mouldy is bundled into the ear of maize of 7～10 jin of weights with it.

(2) do the pond of prewetting: the pond of digging or build a long 2m, wide 1m, dark (height) 1m.

(3) preparation soak: pour into clear water in the pond of prewetting, pouring into the water yield is 2/3 of the pond volume of prewetting, and the weight of then pressing water adds the EM beneficial organism bacterial classification of 2～3% weight ratios.

(4) soak material: will bundle good stalk ear of maize and drop in the pond, and with weight its submerged immersion be picked up after 20 minutes, and be placed on the edge, pond and pass back in the pond by remaining water in the stalk ear of maize.

(5) ferment: the stalk ear of maize that with water content is 50-60% is neat by unanimously discharging end to end, and the windrow width keeps flat as main take two groups of ears of maize connections; High 30～the 40cm of every heap evenly spreads one deck rice bran, and the rice bran amount of being sprinkled into is 2% of stalk ear of maize weight; Then spray concentration is the EM bacterium liquid of 6% weight ratio; Hide with plastic foil when windrow is disposed to highly about 1.5m and begin to ferment; When temperature in the windrow reaches 60～70 ℃, keep stirring after 3 days, continue fermentation and finish fermentation after 3 days.

(6) bacterium rod bag: select the plastic sack of length 1～1.2m, diameter 50～60cm excellent with bag as producing the cultivation bacterium.

(7) preparation is every mud: select pond sludge or vegetable garden mud, and admix 0.2 kilogram of urea, 0.2 kilogram of potassium dihydrogen phosphate by 100 kilograms of earth, and with the liquor potassic permanganate of 0.1% weight ratio with mud mix to water content be about 60～65%.

(8) inoculation: first toward bacterium rod bag spread a layer thickness be 8～10cm every mud, then spreading a layer thickness is 30～40cm stalk, spills uniformly liquid spawn toward stalk again, liquid bacteria access amount is 3～4% of stalk ear of maize weight; Tighten sack after full with bacterium rod is packed by above-mentioned technique always, and with pin bacterium rod bag is pricked all over air-vent.

(9) cultivation: carry out cultivation in temperature is 20～25 ℃, relative moisture about 80～85% and dark culturing room, general about 10 days, mycelia was all covered with bag.

(10) management of producing mushroom: can be with bacterium rod bag two and middle Zha Chugukou when yellow water appears in the bacterium rod, will increase illumination and ventilation this moment, and when the fruiting mouth grew a large amount of little mushrooms, cultivating indoor relative humidity will reach about 95～98%.

(11) pluck: when cap length to 10 centimetre, can gather; After all having gathered, stop to spray water 4～6 days, mycelia is in returns to form, past bacterium rod again can grow little mushroom on the bacterium pier every the water filling of mud place after several days again, and management method is the same.

Compared with prior art, the existing following advantage of the present invention:

1, the present invention be directly with pure long stalk as planting material, do not need cut off to pulverize.

2, the present invention uses EM beneficial organism bacterial classification and carries out fermented stalk, makes the stalk base-material be able to high effect ground and softens, in order to the decomposition utilization of mycelia.

3, the present invention uses the larger plastic sack of volume as bacterium rod bag, produces so soon, and two people cooperate one ton of raw material of cultivation in a day, improve several times than common plastics bag cultivating efficient.

4, applying liquid spawn inoculation of the present invention, the liquid spawn speed of production is fast, and the bacterial classification source is wide, behind the access liquid spawn, liquid spawn is flowed, and so just is penetrated into the forage the inside, and bacterial classification one is sprouted, all material feeding is covered with soon, does not allow the miscellaneous bacteria dip-dye, and fruiting is fast.

5, the present invention's application as thermal insulation layer, can guarantee that this technique can the production of realization anniversary with the earth of nutrient like this.

6, during final-period management of the present invention, clear water with nutrient solution absorbs and slowly carry moisture toward the bacterium rod, sufficient and balanced moisture and nutrition have guaranteed output by mud separating layer.
