Selenium-rich fertilizer for sugar oranges and preparation method thereof

Abstract

The invention relates to the technical field of fertilizers and particularly relates to a selenium-rich fertilizer for sugar oranges and a preparation method thereof. The fertilizer is mainly preparedfrom tea bran, animal feces and urine, wheat germ flour, asparagus powder, nutgrass flatsedge, radix asteris, atriplex halimus, sodium selenite, selenium ore powder, selenylated carrageenan, carboxypropyl cellulose, concentrated molasses fermented powder, a pesticide, and microorganisms. The preparation method includes steps of raw material treatment, fermentation, filtration, blending, granulation, drying and the like. The selenium-rich fertilizer is rich in nutrition and has sterilization and pesticidal effects, can reduce plant diseases and insect pests and reduce use frequency of pesticides and chemical fertilizers, significantly increases the Mu yield, soluble solid content and selenium content of the sugar oranges, is high in nutritional value, is simple in preparation method and iseasy to produce.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a selenium-enriched fertilizer and a preparation method thereof. Background technique [0002] Selenium is an indispensable non-metal trace element in human life. It can decompose free radicals in the human body, and reduce the harmful peroxides in the human body to harmless hydroxyl compounds, thereby improving the ability of the human body to resist aging, immunity and hormone secretion. Selenium deficiency in the human body may cause energy deficiency malnutrition, hemolytic anemia, Keshan disease, Kashin-Beck disease, hypertension and other diseases. The World Health Organization has realized the dangers of selenium deficiency, so various selenium-supplementing health care products are produced in large quantities. However, for modern people who are increasingly pursuing health, people very much hope to use food supplements instead of medicine supplements. In recent yea...

Problems solved by technology

[0003] At present, although there are many selenium-enriched fertilizers related to fruit trees on the market, the functions of selenium-enriched fertilizers on the market are relatively single, and most of them only provide selenium content alone, and have no other functions (such as insecticidal and bactericidal, etc.), so fruit tree diseases and insect pests Serious, resulting in increased pesticide residues, seriously endangering human health, polluting the environment, and the obtained fruit not only has thick skin, but also has less water and less sugar, which is difficult to meet the requirements of growers and markets
