Selenium-rich bio-organic fertilizer for fruits and vegetables and preparation method thereof

Abstract

The invention discloses a selenium-rich bio-organic fertilizer for fruits and vegetables, comprising 15-20 parts of sheep manure, 25-35 parts of cow dung, 15-20 parts of straws, 10-15 parts of rice bran, 8-12 parts of bone meal, 5-8 parts of chaff carbon, 2-3 parts of selenium-rich materials, 4-7 parts of biological bacteria, 1-2 parts of Azolla imbricata, 2-3 parts of nitrogen-fixing blue-green algae, 2-4 parts of humic acid, 3-5 parts of fulvic acid, 1-2 parts of chitosan, 1-2 parts of trace elements, and 4-7 parts of amino acid fertilizer. By adding animal waste, agricultural waste and other plant fibers, comprehensive nutrition is provided for growing fruit and vegetable crops, organics and fertility are increased for soil, soil temperature is increased, and photosynthetic effect is promoted for fruits and vegetables, the selenium content and the like is effectively increased for fruits and vegetables; the biological bacteria can ferment animal waste, agricultural waste and other plant fibers, the wastes are recycled, and the environment is protected.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a selenium-enriched bio-organic fertilizer for fruits and vegetables and a preparation method thereof. Background technique [0002] Selenium is honored as "the fire of life" by the medical and nutritional circles at home and abroad, and enjoys the reputation of "longevity element", "king of anti-cancer", "patron saint of the heart" and "natural antidote". The content of selenium in human tissue is 1 / 10000000, but it determines the existence of life, and its great effect on human health is irreplaceable by other substances. Selenium deficiency will directly lead to the decline of human immunity. Clinical medicine has proved that more than 40 kinds of diseases that threaten human health and life are related to human selenium deficiency, such as cancer, cardiovascular disease, liver disease, cataract, pancreatic disease, diabetes, reproductive Systemic diseases and so on.
