Abstract

The invention discloses a culture medium of selenium-enriched hericium erinaceus. The culture medium is prepared by the following accessories and ingredients in parts by weight: the ratio of the weight parts in main culture materials among cotton seed hull, wheat bran and selenium-enriched soil is 6: 3: 1; and the weight parts of the accessories in the culture medium are as follows: 30-35 parts of broad leaf wood chip, 20-25 parts of dry cow dung, 2-3 parts of fructose, 2-4 parts of urea, 1-2 parts of gypsum, 500 ppm of sodium selenite, 1000 ppm of ammonium molybdate, 800 ppm of zinc sulfate and 1000 ppm of monocalcium phosphate. The culture medium of the invention has the advantages of vigorous growth of thallus, higher content of selenium in hericium erinaceus, higher nutritional value of thallus, high utilization rate of bacterial strains to the culture medium, high biological conversion rate and low cost, and improves the economic benefit for cultivating hericium erinaceus.

Description

The substratum of a kind of rich selenium Hericium erinaceus (Bull. Ex Fr.) Pers.

 

Technical field:

The present invention relates to the production field of Hericium erinaceus (Bull. Ex Fr.) Pers., relate in particular to a kind of configuration of Hericium erinaceus (Bull. Ex Fr.) Pers. nutrient media components.

 

Background technology:

Hericium erinaceus (Bull. Ex Fr.) Pers. is the traditional luxury dish of China, and meat is tender, taste is fragrant, tasty.One of four large famous dishes (hedgehog hydnum, bear's paw, sea cucumber, shark's fin).The title that has " mountain delicacy hedgehog hydnum, seafood delights bird's nest "; The nutritive ingredient of Hericium erinaceus (Bull. Ex Fr.) Pers. is very high, and every hectogram, containing 26. 3 grams, protein, is two times of mushroom.It contains much 17 kinds of amino acid, and wherein needed by human body accounts for 8 kinds.Fatty 4.2 grams of every hectogram hedgehog hydnum, is genuine high protein, low-fat food, is also rich in addition various VITAMIN and inorganic salt.Hericium erinaceus (Bull. Ex Fr.) Pers. improves a poor appetite, and strengthens barrier of gastric mucosa function, improves lymphocyte transformation rate, promotes the effects such as white corpuscle.

What current Hericium erinaceus (Bull. Ex Fr.) Pers. substratum on the market adopted is wood chip 26%, wheat skin 20%, gypsum or calcium carbonate 2%, sugar 1%, calcium superphosphate 1% is main raw material cultivation Hericium erinaceus (Bull. Ex Fr.) Pers., the carbon source nutritive element of weed tree sawdust is single, the growing environment restriction element of the Hericium erinaceus (Bull. Ex Fr.) Pers. of cultivating is more, output is relatively low, and selecting wheat skin is the nitrogenous source of Hericium erinaceus (Bull. Ex Fr.) Pers. growth, the more difficult Root decomposition by Hericium erinaceus (Bull. Ex Fr.) Pers. of its nitrogen element absorbs, be unfavorable for the expansion of Hericium erinaceus (Bull. Ex Fr.) Pers. bacterial strain and cap, caused nutritive value and the composition of the Hericium erinaceus (Bull. Ex Fr.) Pers. growing out less, the content of trace element is lower, be unfavorable for the eutrophic absorption of people.

In order to address the above problem, it is lower that the present invention proposes a kind of cost, is rich in the Hericium erinaceus (Bull. Ex Fr.) Pers. substratum of selenium element.

 

Summary of the invention:

The object of the invention is to provide the substratum of a kind of rich selenium Hericium erinaceus (Bull. Ex Fr.) Pers..

Scientific circles' research discovery, the height of blood selenium level is closely bound up with the generation of cancer.A large amount of survey data explanations, regional food and the height of Selenium in Soils content and the sickness rate of cancer have direct relation, for example: food and the selenium content in soil that this is regional are high, the M & M of cancer is just low, otherwise, the cancer morbidity that this is regional and mortality ratio are just high, the generation close relation of statement of facts selenium and cancer.Scientific circles also recognize that selenium is " anticancer king " in body trace element simultaneously.Selenium is the activeconstituents that forms Selenoperoxidase, and it can prevent beta Cell of islet Oxidative demage, makes its function normal, promotes sugar part metabolism, reduces blood sugar and glucose in urine, improves diabetic subject's symptom.

For achieving the above object, the present invention proposes the substratum of a kind of rich selenium Hericium erinaceus (Bull. Ex Fr.) Pers., by batching and the auxiliary material of following parts by weight, is prepared from:

Cultivating weight part in major ingredient is: cotton seed hulls: wheat bran skin: rich selenium soil=6:3:1;

In substratum auxiliary material, weight part is: broad-leaved wood chip 30-35, dry cow dung 20-25, fructose 2-3, urea 2-4, gypsum 1-2, Sodium Selenite 500ppm, ammonium molybdate l000ppm, zinc sulfate 800ppm, monocalcium phosphate l000ppm;

The substratum of above-mentioned rich selenium Hericium erinaceus (Bull. Ex Fr.) Pers. is by weight being major ingredient: auxiliary material=5:1 configuration forms;

Above-mentioned rich selenium soil is for containing the earth of the rich selenium element that selenium element wt mark is 2%-5%.

The invention has the beneficial effects as follows, proportioning is simple, easy to use, when reducing traditional culture medium cost, has effectively guaranteed the selenium constituent content of Hericium erinaceus (Bull. Ex Fr.) Pers..And biologicak efficiency is high, method is simple, and cost is low, is easy to promote.

 

Embodiment:

Embodiment 1

The preparation of the substratum of the method for cultivation of a kind of rich selenium Hericium erinaceus (Bull. Ex Fr.) Pers..Substratum has major ingredient and auxiliary material cooperation to form.Substratum major ingredient weight part is: cotton seed hulls: wheat drum head: earth=60 kilogram: 30 kilograms: 10 kilograms.Substratum auxiliary material weight part is broad-leaved wood chip 35, dry cow dung 20, and fructose 3, urea 2, gypsum 1, Sodium Selenite 500ppm, ammonium molybdate l000ppm, zinc sulfate 800ppm, monocalcium phosphate l000ppm, takes 20 kilograms by above-mentioned weight part.Get 100 kilograms of major ingredients, 20 kilograms of auxiliary materials mix.

Use the Hericium erinaceus (Bull. Ex Fr.) Pers. of cultivation of the present invention and the contrast of traditional Hericium erinaceus (Bull. Ex Fr.) Pers. as follows:
