[0072] ①Screen, dry, and crush corn cobs, a kind of natural crop waste, to a particle size of 0.005-0.1mm, and design the formula of the cultivation material additive required for the cultivation of selenium-enriched Pleurotus eryngii.

[0073] The additive formula is as follows:

[0074] 100 parts of corncob flour;

[0075] Sodium selenite 0.0011~0.0022 parts.

[0076] ② Grind the above sodium selenite to a powder with a particle size of 0.005-0.1 mm, and fully stir and mix with corncobs to obtain a mixture with a particle size of less than 0.1 mm and a selenium content in the range of 5-10 mg / kg.

[0077] ③ Process and granulate the above mixture to make it into particles with different particle sizes, and the particle sizes are controlled within the ranges of 0.005-0.1mm, 0.1-1.0mm, and 1.0-5.0mm respectively.

Abstract

The invention discloses a method for carrying out rich-selenium culturing of plelmtus eqngiu by utilizing sodium selenite. The method provided by the invention is characterized by comprising the following steps: mixing a rich- selenium culturing material additive the weight of which accounts for 1-10% of the total weight of a culturing dry material into the culturing dry material; culturing according to a common culturing method, thus obtaining rich-selenium plelmtus eqngiu, wherein the content of the selenium in the rich- selenium culturing material additive is 0.5-100mg / kg, the numerical values of the particle sizes of the particles of the rich-selenium culturing material additive are distributed in multiple different numerical vaue intervals within a range from 0.005mm to 5.0mm, the particles with the particle size of 1.0-5.0mm accounts for 10wt% of the total additive, and the particles with the particle size of 0.005-0.1mm at least accounts for 40wt% of the total additive; and therich-selenium culturing material additive is prepared from the following raw materials in parts by weight: 100 parts of corn cob powder and 0.0011-0.022 part of sodium selenite. The plelmtus eqngiu cultured by the method has the advantages of high selenium utilization ratio and stable selenium content in batches; and the method ensures no hidden selenium contamination trouble and is convenient tooperate and easy to popularize.

Description

technical field [0001] The invention relates to edible fungi, in particular to a method for strengthening selenium nutrition of Pleurotus eryngii 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. .
