Problems solved by technology

Since the biological half-life of selenium is about two weeks, it metabolizes quickly in the body and must be supplemented continuously. Therefore, scientific supplementation of selenium is a worldwide problem. Supplementing inorganic selenium is not easy to be absorbed by the human body, and it is easy to be poisoned. rise

Embodiment 1

[0059] A preparation method of selenium-enriched organic fertilizer comprises the steps:

[0060] (1) 20kg of selenium-enriched edible fungus culture waste (the culture medium discarded after cultivating organic-selenium-rich shiitake mushroom strains in Example 3 of CN102960184A) and 80kg of poultry manure were pulverized respectively, and mixed to obtain 100kg of base material;

[0061] (2) Add 0.3kg of a mixture of Saccharomyces cerevisiae and lactic acid bacteria (mixing ratio 3:1) to the 100kg of base material obtained in step (1), and ferment after mixing evenly. Turn over once; ferment for 5 to 7 days to obtain the fermented material, and reduce the moisture content of the fermented material to 25%;

[0062] (3) Add 3.5kg of biological nitrogen, 3.5kg of biological phosphorus, 3.5kg of biological potassium, 15kg of humic acid, 0.35kg of calcium carbonate, 0.35kg of ferrous sulfate, 0.35kg of The borax trace element of zinc sulfate, 0.35kg, through mixing, pulverizing, ...

Abstract

The invention relates to a preparation method of an organic selenium-rich fertilizer. The preparation method comprises the following steps of: (1) smashing and mixing an edible selenium-rich fungus cultivation waste with animal dungs, thereby obtaining a basic material, and fermenting the basic material by adding fermentation bacteria; (2) adding biological nitrogen, biological phosphorus, biological potassium, humic acid and trace elements into the fermenting material obtained by the step (1), mixing, smashing and screening the fermenting material, thereby obtaining a powder product; and optionally, carrying out the step (3) after the finishing of the step (2): granulating the powder product to obtain granule products. By selecting the component types and the component content of the raw materials of the organic selenium-rich fertilizer and optimizing the preparation process, the preparation method of the organic selenium-rich fertilizer is obtained. The preparation method is simple and convenient to operate, and low in cost and is environment-friendly.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to a selenium-enriched organic fertilizer and a preparation method thereof. Background technique [0002] Selenium is a multifunctional life nutrient that can scavenge free radicals, resist oxidation, strongly inhibit the generation of peroxidation properties, enhance immune function (20-30 times), protect biological cell membranes, enhance prostate regulation, prevent blood clots, Cholesterol removal has the same effect as insulin, which can significantly promote the ability of cells to absorb sugar and blood circulation, prevent skin aging, reduce the carcinogenicity of carcinogens, remove mutated cancer cells in the body, and prevent the division and growth of cancer cells. [0003] Yu Ruomu, a famous nutritionist in my country, pointed out that selenium should be supplemented like iodine supplement, and wrote the inscription "Selenium-enriched food, healt...
