A kind of method of utilizing cotton stalk powder culturing edible fungus
Technical field
The present invention relates to a kind of method of utilizing cotton stalk powder culturing edible fungus, belong to technical field of edible fungi production.
Background technology
Edible mushroom is that a kind of people like eating; And the vegetable food that is of high nutritive value; Also be the good project that vast farmers is used for shaking off poverty and setting out on the road to prosperity, though natural wild edible mushroom is nice, because of the restriction of weather or geographical conditions; This natural wild edible fungus must be finished seldom, can not satisfy numerous town dwellers' consumption demand.Therefore; The edible mushroom that disappears and sell on the vegetables market at present all is that artificial cultivation comes out generally, and its method is to be transplanted to the edible fungus species of different cultivars on the medium of multiple different materials; Under manually operated temperature humidity condition, let it grow into different edible mushrooms; The culture medium of edible fungus that past people adopts is to adopt cotton seed hulls, rape shell or other plant property fiber mostly; Because these raw materials itself are just few, add that the people of use is many, cause the culture medium of edible fungus raw material nervous; Price is constantly soaring, is that raw material is used as medium though big, the inexpensive cotton stalk of people's employing amount is arranged, because of its composition of raw materials or cultivation method improper; Cause product bacterium rate not too high, be difficult to penetration and promotion.
Summary of the invention
The purpose of this invention is to provide a kind of new method with cotton stalk powder culturing edible fungus, availability and product bacterium rate in order to improve cotton stalk reduce the Edible Fungi cost, simplify culture technique, promote shaping up of edible mushroom industry.
The inventor has been engaged in research and the production of edible mushroom since 1993 always; Particularly since 1997 just always research experiment make the medium of edible mushroom with cotton stalk; Effort through for many years sums up a rational formula and a culture technique of making culture medium of edible fungus with the cotton stalk powder at last: the composition and the percentage by weight of the cotton stalk powder culture medium of edible fungus that the present invention adopts are: cotton stalk powder 55-60%, fine earth 10-15%; Wheat bran 20-25%; Superphosphate 0.5-2%, lime 1-3%, urea 0.1-0.5%.
The cultivation method that the present invention adopts, it comprises the steps:
1, gets the raw materials ready: get all the whole culture medium raw materials ready by the above-mentioned raw materials proportioning;
2, pulverize: use cracker that cotton stalk powder is broken into the powder of diameter as 8-10mm;
3, make the dark liquid of fertilizer: with superphosphate, lime and urea are put into water and are dissolved;
4, fermentation: cotton stalk powder, fine earth and the wheat bran after will pulverizing is with making the fertilizer aqueous solution, after stirring, by every square metre of windrow 50kg heap fermentation, turns over the secondary heap in per 24 hours, extremely when the temperature of turning sour reaches 100 ℃, just stops to ferment;
5, pack sterilization: with raw material by fermentation, use plastic bag packaging, under 100 ℃ of high temperature, kept 8~10 hours, reach the purpose of sterilization;
6, inoculate, go into canopy: the former pocket that will sterilize, the two ends of flat mushroom strain implantation packaging bag, put into the preprepared plastic tunnel then; Keep 20~25 ℃ of temperature in the canopy; Humidity remains on 70~80%, keeps health in the canopy, prevents the intrusion of worm poison; Prevent that assorted bacterium from producing, the edible mushroom that grows after 28 days just can go out canopy and go on the market.
Compared with prior art, the present invention has following advantage:
1, cotton stalk is the main discarded object of special cotton growing area, rural area, and not only quantity is many, and the occupation of land time is long; Also, also be difficult to handle, cause many troubles to the cotton grower because be difficult to pull out from ground; With its be used for the growth edible mushroom raw material after, be not only twice laid, turn waste into wealth; Also, reduce many troubles for the cotton grower has found a kind of approach of handling cotton stalk;
2, doing edible mushroom with the cotton stalk powder, to cultivate other batching few, reasonable mixture ratio, and cost is low, can also improve the output of edible mushroom, and compares as base-material with cotton seed hulls, and not only cost reduces by 70%, and the output of edible mushroom also will increase by 30%;
3, production method is simple, and easy operating helps applying;
4, applied widely: the medium of this cotton stalk preparation of powder, can production multiple eating bacterium, through experiment, its is fit to the cultivating and growing of chicken pin mushroom, Asparagus, particularly mushroom and flat mushroom.
[embodiment]
Below in conjunction with embodiment the present invention is further specified:
Embodiment 1: with the method that the cotton stalk powder is cultivated flat mushroom, it comprises the steps:
1. get the raw materials ready: get all the following raw material of cultivating base by weight ratio ready, cotton stalk 55%, fine earth 15%, wheat bran 25%, superphosphate 0.5%, lime 1%, urea 0.1%;
2. pulverize: with pulverizing machine with stainless steel after the cotton stalk drying, be ground into the powder that diameter is 8mm, for use;
3. making fertilizer solution: superphosphate, lime and urea are put into container, blunge, it is dissolved fully, it is for use to process fertilizer liquid;
4. fermentation: cotton stalk powder, fine earth and wheat bran after will pulverizing, mix stirring with the fertilizer water of processing, again with the powder of mixing thoroughly; By every square metre of 1~50kg windrow; Standing for fermentation, turning in per 24 hours once extremely stop fermentation when the powder fermentation temperature reaches 100 ℃;
5. pack sterilization: powder by fermentation, pack with plastic sack, every bag of 0.5~1kg, then in closed container with 100 ℃ of high-temperature sterilizations 8 hours;
6. canopy is gone in inoculation: with the former bag of culture medium after sterilization, be cooled to normal temperature after, the two ends with flat bacterium mushroom kind is implanted the culture medium raw material bag move into booth with it then; Keep 20~25 ℃ of room temperatures in the canopy, remain on 70~80% humidity, keep health in the canopy therebetween; Prevent worm poison invasion, prevent varied bacteria growing, leave standstill just can go out canopy in 28 days and gone on the market; Survey factually, the former pocket of every 0.5kg, every bag of flat mushroom that can grow 2kg comes.
Embodiment 2: with the method that the cotton stalk powder is cultivated mushroom, it comprises the steps:
1. get the raw materials ready: get all the following raw material of cultivating base by weight ratio ready, cotton stalk 60%, fine earth 10%, wheat bran 20%, superphosphate 2%, lime 3%, urea 0.5%;
2. pulverize: with pulverizing machine with stainless steel after the cotton stalk drying, be ground into the powder that diameter is 10mm, for use;
3. making fertilizer solution: superphosphate, lime and urea are put into container, blunge, it is dissolved fully, it is for use to process fertilizer liquid;
4. fermentation: cotton stalk powder, fine earth and wheat bran after will pulverizing, mix stirring with the fertilizer water of processing, again with the powder of mixing thoroughly; By every square metre of 1~50kg windrow; Standing for fermentation, per 24 hours turning secondaries are to when the powder fermentation temperature reaches 100 ℃, stopping fermentation;
5. pack sterilization: powder by fermentation, pack with plastic sack, every bag of 0.5~1kg, then in closed container with 100 ℃ of high-temperature sterilizations 10 hours;
6. canopy is gone in inoculation: with the former bag of culture medium after sterilization, be cooled to normal temperature after, the two ends with flat bacterium mushroom kind is implanted the culture medium raw material bag move into booth with it then; Keep 20~25 ℃ of room temperatures in the canopy, remain on 70~80% humidity, keep health in the canopy therebetween; Prevent worm poison invasion, prevent varied bacteria growing, leave standstill just can go out canopy in 28 days and gone on the market; Survey factually, the former pocket of every 0.5kg, every bag of mushroom that can grow 3kg comes.
