Problems solved by technology

[0008] The purpose of the present invention is to provide a selenium-enriched corn stalk and a production method thereof, which solves the problems in the prior art that the selenium content of the corn stalk is insufficient and it is difficult to carry out selenium-enriched cultivation, and can be used as a selenium-enriched animal feed and a base material for edible mushroom cultivation. Human beings provide poultry and edible fungus products with safe selenium supplementation

Embodiment 1

[0023] First follow the steps below to produce selenium-enriched biological preparations:

[0024] (1) By weight, put 250kg of pig manure, 100kg of sheep manure, 50kg of rapeseed cake, and 5L of EM raw dew into the fermentation tank, add 150kg of water, cover and ferment for 30 days until there is no odor;

[0025] (2) Add 800kg of water and continue to ferment for 30 days until the solid components in the ingredients are dissolved;

[0026] (3) Take the fermentation broth and filter it with 200 mesh to obtain the mother liquor of selenium-enriched biological preparation;

[0027] (4) Add 6 kg of sodium selenite to 100 L of mother liquor, dissolve and stir evenly without precipitation, and obtain selenium-enriched biological preparations after the reaction is complete.

[0028] The production method of using the selenium-enriched biological preparation for selenium-enriched corn stalks is as follows: under conventional management and cultivation conditions, when t...

Abstract

The invention discloses selenium-enriched corn stalks and a production method thereof. The content of selenium in the selenium-enriched corn stalks ranges from 10 mug / kg to 200ug / kg, and the content of organic selenium is larger than or equal to 70%. The production method includes: when each of corn seedlings subjected to final singling grows 5-6 visible leaves, using 100ml of selenium-enriched biological agent diluted with water 500 times of the biological agent in volume to spray the corn leaves for each acre; when each plant grow 13-14 visible leaves before sprouting of corn male ears, using 300ml of the selenium-enriched biological agent diluted with the water 500 times of the biological agent in volume to spray the corn leaves for each acre; and obtaining selenium-enriched corn stalks after harvesting. Inorganic selenium is converted into organic selenium by microbiological treatment, the organic selenium is then sprayed to plant leaves, and accordingly environment pollution caused by traditional direct supplement of inorganic selenium, such as sodium selenite and the lie, is avoided, produced corn stalks are stable in selenium content and can be used as selenium-enriched animal feed and edible fungus culture medium, safe and selenium-supplementing livestock and edible-fungus products are provided for human, and the selenium-enriched corn stalks have positive significance of improving human selenium level and preventing and treating diseases.

Description

[0001] technical field [0002] The invention belongs to the technical field of production of selenium-enriched agricultural products, and in particular relates to a selenium-enriched corn stalk and a production method thereof. technical background [0003] Selenium is an essential trace element for the human body. It is a multifunctional nutrient element for life. It has anti-oxidation, regulates the body's metabolism, improves the body's immunity and disease resistance, improves the reproductive function, resists tumors, and prevents endemic diseases (such as Keshan disease , Kashin-Beck disease), delaying aging, antagonizing toxic elements and other functions. Studies in recent years have shown that selenium is closely related to the structure and function of the cardiovascular system and the occurrence of diseases. Selenium enzyme-glutathione peroxidase has the functions of reducing peroxide, resisting lipid peroxidation and protecting cell membrane. The heart is ver...
