Summary of the invention
Purpose of the present invention is providing a kind of method for preparing Brazilian mushroom culture medium, and it comprises the compost fermentation handling procedure twice, makes it have the required nutrient of suitable Brazilian mushroom cultivation, so that reach good harvest output.
Another object of the present invention so that supply to do the cultivation of Brazilian mushroom fruit body, and reaches good harvest output at the medium that the special compost fermentation handling procedure of a kind of process is provided.
According to a kind of method for preparing Brazilian mushroom culture medium of the present invention's first purpose, its step comprises: wood chip is piled high 5 to 15 meters carry out the fermentation corruption first time, fermentation time 3 months; The cow dung that adds dry sterilization in the wood chip that fermented is for the first time carried out the fermentation second time, and the wood chip fermentation heap is high 5 to 15 meters, fermentation internal temperature 70 to 80 degree; Above-mentioned first time and when fermenting for the second time, still needed in per 15 to 30 days and to carry out a second periodicity turning, and turning need be poured water this wood chip heap layer till water overflows the heap layer after finishing.At last, when fermentation wood chip color and luster becomes dark brown near black, and the urine that does not have an ammonia disturbs flavor, promptly finishes the processing of this medium.
According to the Brazilian mushroom culture medium of the present invention's second purpose, comprise the wood chip 75% handled through compost fermentation and through the cow dung 25% of sterilization processing.
Brazilian mushroom culture medium as above-mentioned first and second purpose is characterized in that: cow dung the having in the composition can be absorbed and be beneficial to cellulosic, mineral matter and the vitamin of its growth by Brazilian mushroom, and can improve the harvest output of Brazilian mushroom; And the medium after the process secondary fermentation is handled can reduce harmful components wherein, therefore, can grow the Brazilian mushroom that is not detrimental to health.Owing to possessed above all characteristics, so Brazilian mushroom culture medium of the present invention and present same domain technology are compared, except the cultivation that the Brazilian mushroom fruit body can be provided, the meat of its harvest output height, product is tender and crisp tasty and refreshing and do not contain harmful ingredients.
Embodiment
Below only exploitativeness of the present invention and special efficacy thereof are described with preferred embodiment:
A kind of preferable method for preparing Brazilian mushroom culture medium provided by the present invention the steps include: that wood chip piles highly 5 to 15 meters, carries out primary fermentation corruption, about 3 months of time; Carry out periodic wood chip turning; The cow dung that adds dry sterilization in the wood chip of primary fermentation is carried out the fermentation second time, and the wood chip fermentation heap is high 5 to 15 meters, fermentation internal temperature 70 to 80 degree; Carry out periodic wood chip turning; Observe fermentation wood chip color and luster and become dark brown, and the urine that does not have an ammonia is disturbed the preparation that flavor is promptly finished this medium near black.
In the preparation process of above-mentioned Brazilian mushroom culture medium, when carrying out fermenting the second time, wood chip must add the cow dung of dry sterilization, and the sterilization temperature of this cow dung is 60 to 75 ℃.Simultaneously, must add pulverized limestone or calcium carbonate to adjust the ph value of this compost in good time.Control fermentation internal temperature is about 70 to 80 degree when fermenting for the second time, and it is with being intended to allow the wood chip can complete fermentation, and the effect of the capable sterilization of high temperature of generation during by fermentation, avoids residual other assorted bacterium in the medium and influences the growth of Brazilian mushroom.
In the preparation process of above-mentioned Brazilian mushroom culture medium, between first and second time yeast phase, just must carry out once periodic wood chip turning action every 30 days, the purpose of this turning is to allow the abundant and average fermentation of wood chip energy; Must pour water after each turning is intact and pile into this new wood chip, its practice can get final product water pipe by inserting outside water flows out in the middle of the wood chip heap.
In the preparation process of above-mentioned Brazilian mushroom culture medium, judge that this medium after the fermentation for the second time finishes the key of making and be:
The color of wood chip
The wood chip color finished of fermentation is light coffee color (when fermenting for the first time), and when fermentation corruption for the second time, the color of wood chip transfers dark brown to by light coffee color or during near black, promptly is judged as and finishes fermentation.
