Method for cultivating pleurotus eryngii uniformly rich in selenium with mixed organic selenium source

Abstract

The invention discloses a method for cultivating pleurotus eryngii uniformly rich in selenium with a mixed organic selenium source. The method is characterized in that the method comprises the steps of mixing selenium-rich cultivating material additive accounting for 1-10 percent of the total weight of dried cultivating material into the dried cultivating material, and cultivating pleurotus eryngii according to an ordinary cultivation method to obtain pleurotus eryngii uniformly rich in selenium; the selenium-rich cultivating material additive has a total selenium content of 5-50 mg / kg, and needs to be crushed first and then compressed to form particles of certain grain sizes, the grain sizes of the particles in the selenium-rich cultivating material additive are in the range of 0.005-5.0 mm with multi-grain-size regional distribution, the particles having a grain size of 1.0-5.0 mm account for about 10 weight percent of the total weight of the additive, while the particles having a grain size of 0.005-0.1 mm account for at least 40 weight percent of the total weight of the additive. The method has the advantages that the selenium utilization factor of the cultivating material in pleurotus eryngii is high, the selenium content in different batches of picked pleurotus eryngii is stable, therefore, the method is highly safe, convenient to operate, and easy to promote.

Description

technical field [0001] The invention relates to edible fungi, in particular to a method for enhancing selenium nutrition of Pleurotus eryngii by using high-selenium straws, and belongs to the technical field of biotransformation of selenium resources. Background technique [0002] Pleurotus eryngii, also known as Pleurotus eryngii, belongs to the Phylum Fungi, Basidiomycetes, Agaricaceae, Pleurotaceae, and Pleurotus. . Pleurotus eryngii mushroom body is rich in nutrients, has a pleasant almond fragrance and abalone-like taste; the flesh is thick, crisp and tender, especially the stipe is dense, firm, and milky white, and can be eaten entirely, and the stipe is more crisp than the cap Smooth and refreshing. It is rich in protein, carbohydrates, vitamins and minerals such as calcium, magnesium, copper, zinc, etc., which can improve the immune function of the human body. Cardiovascular disease and beauty effects, suitable for fresh-keeping and processing, deeply loved by peo...

Problems solved by technology

[0005] The purpose of the present invention is to provide a method for uniform selenium-enriched cultivation of Pleurotus eryngii by using a mixed organic selenium source, which solves the problem in the prior art between the growth of Pleurotus eryngii head tide after selenium-enriched cultivation or the growth of excessive moisture between Pleurotus eryngii strains. Uneven batches of selenium content, large fluctuations in selenium-enriched fruiting bodies, etc.
