Abstract

According to a selenium-rich organic fertilizer provided by the invention, raw material components are scientifically proportioned, selenium ore rock is used as a selenium source, selenate and selenite with strong oxidizing property are not used, nutrient loss in fermentation raw materials is avoided, seaweed, animal waste, crop straw, rapeseed meal and coco coir are added as humus raw materials, and a carrier is added to improve the fermentation efficiency; and a microbial agent is added for fermentation to obtain the selenium-rich organic fertilizer with high selenium content. Bentonite, quartz sand and acrylamide-starch-acrylate terpolymer are adopted as carriers, the fermentation efficiency is improved, fermented humus can be loaded, the water conservation capacity of soil is improved, and component loss caused by rain wash after the organic fertilizer is applied is avoided.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a selenium-enriched organic fertilizer and a preparation method thereof. Background technique [0002] Selenium is the fire of life, the fifth anti-cancer, the foundation of health, and can effectively prevent and treat more than 40 kinds of human diseases. More than 80% of the countries and regions in the world are low in selenium or deficient in selenium, and 72% of the regions in my country are deficient in selenium. Using plants to realize the transformation of inorganic selenium into organic selenium and increasing the selenium content in food is fundamental to improving the selenium nutrition of humans and animals Measures, plants have a strong ability to enrich selenium, and can actively absorb selenium in the environment. During the plant transformation process, it becomes natural organic selenium through the action of many amino acids in the plant, especially sulfur-con...
