specific Embodiment approach 1

[0016] Specific embodiment one: the cultivation compost of a kind of selenium-enriched fungus of the present embodiment is by weight percentage, and the percentage content of each component of this cultivation compost is: selenium-enriched black currant pomace and twig mixture 30~ 40%, sawdust 40-50%, wheat bran 15-25%, lime 0.5-2% and gypsum 0.5-2%; the selenium-enriched black currant pomace and branch mixture is prepared according to the following method:

[0017] Spray 250 times liquid selenium-enriched fertilizer in the full flowering stage and fruit expansion stage of black currant respectively, and the spraying amount is 40kg / 667m 2 After the black currant is harvested, take the black currant pomace after squeezing the juice and part of the pruned branches, dry or sun-dry it, and crush it into particles with a particle size of 0.2-0.7 cm, to obtain final product;

[0018] The selenium-enriched fertilizer is composed of the following components, and the content of each co...

specific Embodiment approach 2

[0019] Embodiment 2: This embodiment differs from Embodiment 1 in that: the percentage content of each component of the cultivation compost is: 35% to 40% of selenium-enriched black currant pomace and branch mixture, sawdust 43-50%, wheat bran 15-20%, lime 1-2%, and gypsum 1-2%. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0020] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the percentage content of each component of the cultivation compost is: 35% of selenium-enriched black currant pomace and branch mixture, 43% of sawdust , wheat bran 20%, lime 1% and gypsum 1%. Others are the same as in the first embodiment.

Abstract

The invention relates to compost and a method for cultivating selenium-rich auricularia auricula. The compost and the method aim to solve the problems of low selenium content of existing cultivated auricularia auricula and the like. The method includes (1), uniformly mixing 35% of selenium-rich ribes nigrum pomace and branches, 43% of sawdust, 20% of wheat bran, 1% of lime and 1% of gypsum fibrosum with one another to obtain mixtures, adding water into the mixtures, sufficiently uniformly stirring the mixtures and the water to allow the water content of the mixtures to reach approximately 60% and regulating a PH (potential of hydrogen) value of the mixtures until the PH value reaches approximately 8.0; (2), mixing the mixtures, then immediately bagging the mixtures, forming openings, inserting rods into the mixtures, sterilizing and cooling the mixtures, carrying out inoculation and sealing the openings; (3), carrying out spawn running management; (4), accelerating germination and separating spawn in beds; (5), carrying out auricularia auricula producing management; (6), harvesting finished products to obtain the auricularia auricula after auricularia auricula fruiting bodies grow and are mature by 80%. The compost and the method have the advantages that raw materials for cultivating the selenium-rich auricularia auricula are reasonable in matching and high in selenium utilization rate and are in nutrition balance, auricularia auricula cultivation requirements can be met by C / N (carbon nitrogen ratios), and accordingly the compost and the method have broad development prospects.

Description

technical field [0001] The invention relates to a cultivation method of selenium-enriched fungus and a preparation method of cultivation compost. It is especially suitable for the cultivation of selenium-enriched edible mushroom products. Background technique [0002] Selenium is an essential trace element for the human body. It participates in important metabolic activities of living bodies. The dietary structure of Chinese people has a low selenium intake. Supplementing selenium in food can enhance human immunity and improve physical fitness. Fungi have a good enrichment function for mineral elements. Compared with ordinary edible fungi, selenium-enriched edible fungi have higher biological activity. As an important component of organic selenium in edible fungi, selenium polysaccharides have dual functions of selenium and polysaccharides. Compared with ordinary polysaccharides, it has higher antioxidant activity, anti-tumor activity and activity of enhancing the body's im...
