Problems solved by technology

Both of the above two patents produce selenium-enriched fungi by adding inorganic selenium to the dry material for cultivation; the addition of excessive inorganic selenium, which cannot be absorbed by the fungus, will cause a large amount of selenium to remain in the dry material for cultivation, causing irreparable damage to the environment. pollution

Embodiment 1

[0019] During the booting stage and filling period of rice, organic selenium fertilizer is sprayed on rice leaves, and the rice straw is dried in the sun after harvesting to obtain selenium-enriched rice straw, and then the dry material for the cultivation of Agaricus bisporus is formulated according to the following components by mass: Selenium-enriched rice 55 parts of straw, 35 parts of cow dung, 0.3 parts of urea, 5 parts of phosphate fertilizer, 3 parts of gypsum powder, 3 parts of lime, 6 parts of selenium-enriched peanut cake, 3 parts of selenium-enriched psyllium; The amount is 2.0-10.0 mg / kg.

[0020] The cultivation steps of Agaricus bisporus are as follows:

[0021] 1) Material selection Prepare raw materials according to the above-mentioned cultivation dry material formula;

[0022] 2) Pre-wet the selenium-enriched rice straw for composting. 2-3 days before composting, wet or soak the straw to make the straw soaked and maintain sufficient moisture; when composting...

Embodiment 2

[0030] Spray organic selenium fertilizer on wheat leaves during the booting stage and filling period of wheat, and dry the straw after harvesting to obtain selenium-enriched wheat straw, and then prepare the dry material for the cultivation of Agaricus bisporus according to the following components by mass: Selenium-enriched wheat 70 parts of straw, 30 parts of dried chicken manure, 1.2 parts of urea, 3.5 parts of superphosphate, 3 parts of gypsum powder, 3 parts of lime powder, 3 parts of calcium carbonate, 6 parts of selenium-enriched astragalus; among them, selenium-enriched wheat straw contains selenium The amount is 2.0-10.0 mg / kg.

[0031] After testing, the selenium content of Agaricus bisporus cultivated according to the cultivation dry material of this example and the cultivation steps of Example 1 is 0.2-1.5 mg / kg, and the taste is better than that of common Agaricus bisporus.

Abstract

The present invention discloses a selenium-rich agaricus bisporus production method using selenium-rich crop straws. Selenium-rich crop straws with 50%-70% of the total weight of cultivation dry materials are mixed into the cultivation dry materials. The selenium-rich agaricus bisporus production method uses natural selenium-rich crop straws as raw materials, has a high selenium utilization and no pollution problems, and can solve the crop straw recycling problem, is environmentally friendly, is simple and easy to operate, and improves the selenium content of agaricus bisporus to 0.2-1.5 mg / kg.

Description

technical field [0001] The invention relates to a method for producing selenium-enriched Agaricus bisporus by utilizing selenium-enriched crop straws. Background technique [0002] Patent CN101637101A discloses an industrial cultivation method of selenium-enriched Agaricus bisporus, which mainly produces selenium-enriched Agaricus bisporus by adding sodium selenite to the dry material for cultivation. Patent CN101921146A discloses a method for cultivating edible fungi such as selenium-enriched fungus with 99.9% selenium-containing ultrafine selenium ore powder as a selenium source. , the conversion of inorganic selenium to organic selenium is achieved through the cultivation of edible fungi. Both of the above two patents produce selenium-enriched fungi by adding inorganic selenium to the dry material for cultivation; the addition of excessive inorganic selenium, which cannot be absorbed by the fungus, will cause a large amount of selenium to remain in the dry material for c...
