Problems solved by technology

[0005] At present, inorganic selenium such as sodium selenite is often used as a selenium source to cultivate selenium-enriched oyster mushrooms, which is highly toxic and threatens the health of practitioners. The absorption and utilization rate of selenium is low, and there is a potential pollution; , poor food safety
Organic selenium sources with low toxicity, such as protein selenium and yeast selenium, are often sprayed on the surface of crops to enrich selenium. This method is costly and has poor selenium enrichment effect. It does not use large-scale promotion

Embodiment 1

[0026] (1) Preparation of cultivation bags: Soak the crushed corncobs in a selenium-enriched solution with a selenium content of 50 mg / kg prepared from arginine selenate for 12 hours, and then mix them with other main and auxiliary materials in the cultivation material. The percentage of main and auxiliary material dry weight of cultivation material is:

[0027] Corncob: 45%;

[0028] Cottonseed hulls: 45%;

[0029] Bran: 9%;

[0030] Cornmeal: 1%;

[0031] Lime: 0.05%.

[0032] Adjust the water content of the cultivation material to 55%, and the selenium content to 25mg / kg, stir and mix well, put it into a plastic bag, and seal it with a ring after drilling.

[0033] (2) Sterilization: Put the cultivation bag into the sterilization chamber, the temperature reaches 100°C, steam sterilization for 12~14 hours, and keep warm for 10 hours after stopping the heating.

[0034] (3) Cooling: After the sterilization is completed, open the hatch, and when the temperature drops to 8...

[0039] (1) Preparation of cultivation bags: Soak the crushed corncobs in a selenium-enriched solution with a selenium content of 100 mg / kg prepared from arginine selenate for 12 hours, and then mix them with other main and auxiliary materials in the cultivation material. The percentage of main and auxiliary material dry weight of cultivation material is:

[0040] Corncob: 45%;

[0041] Cottonseed hulls: 45%;

[0042] Bran: 9%;

[0043] Cornmeal: 1%;

Abstract

The invention relates to a cultivation method for selenium-enriched oyster mushrooms with small mushroom caps and large stipes. The cultivation method comprises the following steps: preparing a cultivation bag; sterilizing; cooling; inoculating; managing a greenhouse, and the like. The total selenium amount of selenium-enriched cultivation materials is 10-50mg / kg and selenic acid arginine is used as a selenium source; main materials and auxiliary materials adopted by the selenium-enriched cultivation materials are as follows in dry parts by weight: 45% of corncobs, 45% of cottonseed hulls, 9% of bran, 1% of corn meal and 0.05%-0.1% of lime. The selenic acid arginine is used as the selenium source so that the toxin is small and the safety is high; the absorption utilization rate of the selenium is high. The selenium content of sporocarps of the obtained selenium-enriched oyster mushrooms is high, the residual amount of the inorganic selenium is less and the eating safety is high; the disadvantage that the selenium content of the oyster mushrooms is lower is made up and the nutritional health value of the oyster mushrooms is improved. The sporocarps of the selenium-enriched oyster mushrooms have the small mushroom caps and the large stipes, the mouth feel and the appearance quality of the selenium-enriched oyster mushrooms are greatly enhanced and the commodity value of the oyster mushrooms is improved.

Description

technical field [0001] The invention relates to a method for strengthening selenium nutrition and improving the quality of edible mushrooms, in particular to a method for strengthening selenium nutrition and cultivating selenium-enriched oyster mushrooms with small caps and large stalks by using arginine selenate as a selenium source. Background technique [0002] Selenium is one of the essential trace elements for the human body. It is the active center of various enzymes such as glutathione peroxidase, deiodinase, and thioredoxin reductase. It is of great significance for maintaining normal physiological functions of the human body. Studies have found that selenium has various physiological functions such as anti-oxidation, improving the oxygen-carrying capacity of red blood cells, improving human immune function, protecting cardiovascular and myocardial health, preventing and fighting cancer, affecting human thyroid metabolism, and being a natural antidote for various meta...
