Abstract

The invention discloses a method for culturing edible fungus. Furfural residue is used as the main material of the culture medium; the furfural residue is dross formed by acidizing corn cob and the like at high temperature, and thus, does not have infectious microbes; the furfural residue has a rejuvenation action on growth of the edible fungus, can not be easily polluted after inoculation, and has the advantage of heavy hypha growth; and the whole growth period is approximately the same as that of a common culture medium.

Description

A kind of cultivation edible mushrooms method

Technical field

The present invention relates to microbial technology field, particularly a kind of cultivation edible mushrooms method.

Background technology

Mushroom industry is a new industry and sunrise industry.Edible fungus is nutritious with it, medicinal health, environmental protection feature, be subject to the welcome of various countries human consumer, be recommended as one of large heath food in the world ten by international nutritionist, market potential is huge.Mushroom industry is also more typical labor-intensive industry, not by the restriction of the condition such as soil property, illumination, with short production cycle, instant effect, high efficiency, is applicable to very much vast rural area and manages.Development mushroom industry, for the optimization structure of rural undertaking, increases farmers' income, improves the living standards of urban and rural residents, all have important practical significance.

The original seed of edible mushrooms and the culture medium of cultivar adopt natural vegetable material to do matrix mostly, as cotton seed hull, wood chip/wooden grain, corn cob, grass meal, cereal, bamboo chip/joint etc., easily make block mycelium broken in seeded process, after inoculation, survival rate is not high.Natural vegetable material does strain substrate, and inoculation block is easily crushed, and easily cause inoculation to be polluted, mycelium survival rate declines, the problems such as the easy dehydration of bacterial classification is aging, and substratum is in the easy dehydration of container contents, and mycelium is easily aging, and the storage time is very limited.

Furfural is from corn cob, bagasse, the organic compound extracted in the agricultural-product tankage such as wheat straw, raw material used is just consistent with the basic raw material of culture medium of edible fungus, remaining furfural dregs after extraction furfural is carried out content analysis show, Mierocrystalline cellulose contained by it, xylogen, protein etc. still can reach the needs of edible fungus culturing, as long as carry out neutralizing treatment with lime to its too high acidity, be added into appropriate nutritive ingredient again, go for the cultivation of edible mushrooms completely, so not only can open up the resource of culture medium of edible fungus, and this trade waste of furfural dregs can be fully utilized, turn waste into wealth.

Summary of the invention

The object of this invention is to provide a kind of cultivation edible mushrooms method, specifically, it comprises the steps:

(1) furfural dregs pre-treatment: neutralize by the acidity of lime by useless Technical furfural slag, control PH is 5.5 ~ 6.5;

(2) nutritive medium is prepared: urea 0.5-1.5 part, sucrose 2-4 part, wheat bran 10-15 part, water 40-50 part are mixed and stirred;

(3) edible mushrooms is cultivated: nutrient solution prepared by furfural dregs step (1) handled well and step (2) mixes according to the ratio of 2:1 and loads inoculation bottle, inoculation; In culturing process, every 2 ~ 3 days concussion seed bottle 10 ~ 30s, after mycelia covers with furfural dregs surface, obtain spendable edible fungus species.

Herbicidal composition provided by the invention has following beneficial effect: because furfural dregs is by the dregs after high temperature acidified process such as corn cob, thus wherein without miscellaneous bacteria, rejuvenation effect is had to edible fungi growth, not easily pollute after inoculation, mycelial growth is vigorous, and whole growth cycle is roughly the same with general substratum.

Embodiment

Be further described the specific embodiment of the present invention below in conjunction with embodiment, following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.

Embodiment 1

The concrete technical scheme of the present invention is as follows:

(1) furfural dregs pre-treatment: neutralize by the acidity of lime by useless Technical furfural slag, control PH is 5.5 ~ 6.5;

(2) nutritive medium is prepared: 1.0 parts, urea, sucrose 3 parts, 15 parts, wheat bran, 45 parts, water are mixed and stirred;

(3) edible mushrooms is cultivated: nutrient solution prepared by furfural dregs step (1) handled well and step (2) mixes according to the ratio of 2:1 and loads inoculation bottle, inoculation; In culturing process, every 3 days concussion seed bottle 15s, after mycelia covers with furfural dregs surface, obtain spendable edible fungus species.

The above is only preferred embodiments of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.

Claims (2)
