Description
Technical field
The present invention relates to a kind of fungus growing technique field, particularly relate to a kind of improve Pleurotus ostreatus nutritional labeling,
Reduce culture medium and the preparation method of heavy metal.
Background technology
Pleurotus ostreatus (formal name used at school: Pleurotus ostreatus;Have another name called pick up the ears, oyster cap fungus, oyster mushroom, black Paeonia suffruticosa
Mushroom, Taiwan is also known as Pleurotus geesteranus) it is Agaricales Pleurotaceae one kind under Basidiomycota, it is kind of a fairly common ash
Color edible mushroom, the traditional Chinese medical science thinks that Pleurotus ostreatus is warm in nature, sweet in the mouth.There is effect of wind-evil dispelling and cold-evil expelling, relaxing muscles and tendons and activating QI and blood in the collateral.For
Control the diseases such as lumbago and skelalgia, numb hand and foot, blockage of main and collateral channels.Cancerous cell is had very by the proteoglycan body in Pleurotus ostreatus
Strong inhibitory action, can enhancing human body immunity function.Currently on the market for pursuing the Efficient Cultivation of Pleurotus ostreatus, often
Being commonly incorporated into chemical fertilizer, cause producing Pleurotus ostreatus head big, yield is many, but reduces nutritional labeling, heavy metal
Content is high, and poor quality, mouthfeel is poor.
Vast researcher has been carried out greatly for the technology improving Pleurotus ostreatus nutritional labeling and reduction content of beary metal
Quantity research works, and mainly provides following two for cultivating the culture medium of Pleurotus ostreatus:
Method 1, a kind of culture medium improving Pleurotus ostreatus nutritional labeling, count by weight and include: distiller grains 80-90
Part, Pulvis Talci 2.5-2.7 part, soybean germ powder 4-5 part, ferrous citrate preparation 1-1.4 part, bamboo send out

Part, quick lime 3-5 part, potassium dihydrogen phosphate 0.2-0.3 part, fish soup 15-18 part, Nutrition Soil 1-2 part.
The Pleurotus ostreatus of the culture medium cultivation that method 1 and method 2 provide has individual big, in good taste, nutritious
Feature, but Media Components is extremely complex, increases the production cost that Pleurotus ostreatus produces, and is unfavorable for producing and promotes;
But the content of beary metal of Pleurotus ostreatus does not reduce.
Separately, the type of existing oyster mushroom culture medium is the most various, and generally speaking component is the most complex, though carrying
High nutrition aspect tool has certain effect, but is reducing the DeGrain of content of beary metal, simultaneously by
The most complex in its component so that in production practices, to be difficult to operation, and also increase production cost and labor
Make the time.
Therefore, need one badly and can improve Pleurotus ostreatus nutritional labeling, Pleurotus ostreatus content of beary metal, and group can be reduced again
Divide simple, low cost and culture medium convenient to operation.
Summary of the invention
It is an object of the invention to provide a kind of improve Pleurotus ostreatus nutritional labeling, reduce heavy metal culture medium, should
Nutrient media components is simple, low cost and convenient to operation.
Another object of the present invention is to provide a kind of and improve Pleurotus ostreatus nutritional labeling, the culture medium of reduction heavy metal
