Mushroom of the present invention is an agaricus bisporus.The present invention also is fit to substitute cow dung cultivation Agaricus blazei Murrill, dictyophora phalloidea, can also substitute edible mushrooms such as wheat bran cultivating black fungus.
The training Facilities Construction: adopt mao bamboon, plastic foil and straw to build booth, the mushroom canopy is the rectangle basal plane, rises 5m, the wide 10m of canopy.Bedstead is arranged and is located in the middle of the mushroom canopy, the wide 1.4m of bedstead, and greater than 20cm, top layer is no less than 1.6m from ceiling apart from ground for interlamellar spacing 50cm, bottom, and each bedstead is established 6 layers.Cover whole mushroom canopy with plastic foil, film adds straw screen or mat, and ceiling is established and pulled out tracheae, and both sides are equipped with louver(-vre).
The technological process of production: swine excrement → Separation of Solid and Liquid → pig manure slag+straw → windrow prewets → primary fermentation → after fermentation → cooling cooling → sowing → send out bacterium earthing → management of producing mushroom → adopt mushroom → mushroom products.
(1) outdoor primary fermentation
Build heap: build the preceding 2~3d of heap, the excrement grass is prewetted, and stockpile is with wide 2m, high 1.5m.Every layer of forage 15~18cm is thick, pig manure slag 5cm, and the excrement grass is alternately spread, and about every layer height 25cm, number of plies 10-12 layer is piled stockpile up to more than the 1.5m always.Both required to loosen, tremble unrest during the lay straw, Zha Bianqie wall again, the stockpile limit should be vertical substantially, the bedding muck requires on the limit many, the inside is few, and lower floor is few, and the upper strata is many, evenly add water and urea since the 3rd layer, and successively increase, particularly top layer should keep the pig manure thick-layer to cover, and the top piles turtleback shape, stressor layer in the increase, moisture content are grasped has the low amounts of water outflow to be as the criterion after heap is good.
Turning: the purpose of turning be by at every turn to the stirring of excrement grass, change the fermentation condition at each position of stockpile, regulate moisture, increase nutrient, distribute waste gas, increase fresh air, promote the beneficial microorganism growth and breeding, the heap that raises is warm, deepens fermentation, makes composts or fertilisers of cultivating obtain good conversion and decomposition.Therefore, should be upper and lower during turning, the innner and outer, raw material are relative with grog transposes, and the excrement grass is fully shaken up, dried wet-mixing is closed evenly.
Turning for the first time is after building 3-5 days of heap, still will water sufficient moisture during turning, and layering adds required urea and superphosphate, and moisture is grasped after the turning has a small amount of liquid dung to flow out around the stockpile.
Turning for the second time is behind 3-5 days of the turning first time, 75-80 ℃ of heap Wen Keda, and stockpile reduced width during turning, highly constant, contraction in length, and in stockpile, establish air vent, when turning, the excrement grass of should as far as possible shaking up adds the gypsum layering and is sprinkling upon on the excrement grass, helps even fermentation.Current turning is not watered in principle, and the local teeming low amounts of water of doing must prevent to water dilutional hyponatremia and cause the smelly putrefactive phenomenon of composts or fertilisers of cultivating acid.
Turning for the third time is after the turning second time 2-3 days, can carry out.Turning is highly constant, shortens length, the excrement grass is evenly mixed turn over, and pulverized limestone and calcium carbonate is mixed the back layering be sprinkling upon on the excrement grass.Wet before whole composting process stockpile moisture should be grasped, in do, principle that the back is adjusted.
Composts or fertilisers of cultivating behind the primary fermentation reaches: color is coffee-like, and degree of raw and cooked is moderate, flexible and don't easily break, and material is loose, and water content is 65-68%, and the pH value is at 7.5-8.5.
(2) indoor after fermentation
Self-heating is cultivated: the composts or fertilisers of cultivating through primary fermentation is moved into the mushroom room rapidly, puts on the shelf while hot, piles the ridge type, expects thick 20-30cm.Close the doors and windows, allow its self-heating heat up, self-heating reaches 48-52 ℃, cultivates 2 days;
Heating disinfection: self-heating is cultivated after 2 days gateway, the ventilating opening in mushroom room is closed, and feeds steam and heats up, and carries out pasteurization, and the room temperature in mushroom room rises to 58~60 ℃ and keeps 8~12h;
Temperature control: after the pasteurization, carry out the ventilation of mushroom room short time, make material temperature drop to 50~52 ℃, control this range temperature subsequently and cultivate 3~4d, finish after fermentation.After fermentation can be killed insects such as harmful assorted bacterium of agaricus bisporus growth and mite classes.
(3) sowing
After after fermentation finishes, open ventilating opening, with cultivation and fermentation material leveling, make the bed that it is tight to clap a little, the thickness of cultivation bed is at 18~20 centimetres, when material temperature drop to 25 ℃, can sow, note not can smell the ammonia flavor in the mushroom room this moment, should strengthen ventilation, turn over and tremble windrow if having, disperse ammonia and just can sow, otherwise mushroom is difficult to field planting in composts or fertilisers of cultivating, growth.Sowing is adopted and to be broadcasted sowing method, and the wheat kind is broadcasted sowing, and particle easily disperses to form the many places growing point, spreads field planting everywhere fast, 1~1.5 bottle of every square metre of sowing quantity, and compacting is tied, and closes the doors and windows, and heat and moisture preserving promotes bacterial classification to sprout, but just field planting material feeding in 2~3 days.
(4) send out the bacterium earthing
Sow after 5~6 days, mycelia begins to sprout material feeding.The temperature in mushroom room is controlled at 22~26 ℃ in the meantime, and relative air humidity remains on 70~75%.Mycelia can grow into the material end in after planting 18-20 days.Earthing is selected the field soil at the bottom of the paddy field for use, and its moisture retention is good, and gas permeability is good.The lime clear liquid spraying fine tuning of 0.5~1.2 centimetre of grogs size, grogs, it is flat and not broken that the humidity of grogs is pinched grogs with hand, do not have the white heart, tack-free being advisable.The thickness of overburden layer is grasped at 3~4 centimetres, takes the way of the diligent spray of light spray progressively to transfer to desired moisture level behind the earthing, and mushroom room relative moisture is controlled at about 90%, suitably strengthens ventilation after three days, helps mycelia and climbs soil.
(5) management of producing mushroom
When the mushroom bacteria filament length when the soil layer surface is in the kink state, add forced ventilation, suppress mycelial growth, impel the mycelia kink to form original hase, after original hase forms, begin spray knot mushroom heavy water, spray every day 2~3 times, the light spray of diligent spray, on a small quantity repeatedly, fruiting field temperature is controlled at 10~20 ℃, and relative moisture is ventilated greatly after remaining on about 90% water sprays.After knot mushroom heavy water is transferred foot,, just there are large quantities of mushrooms to grow through about 4d.At this moment in time spray the mushroom heavy water. see mushroom water spray, local many sprays that mushroom is many, spray less in the place that mushroom is few, clear the old mushroom root that is retained in bed surface, dead mushroom after every batch of mushroom is gathered, and mend the lid fine earth that wets.
Output and quality
According to every square metre of output average out to of method of the present invention 11.5kg, the material biological transformation ratio reaches 56.4%.Product quality is accomplished the agaricus bisporus product from the organoleptic indicator, mushroom body white, mushroom shape rounding, full, not parachute-opening, and size is even, no bacterial plaque, foxiness.Agaricus bisporus special delicate fragrance, anacidity, peculiar smell, free from insect pests such as smelly, mould are arranged, water content 90%.Accomplish that from physical and chemical index the agaricus bisporus product quality meets NY5097-2002 " pollution-free food agaricus bisporus " physics and chemistry sanitary standard.
