Abstract

The invention discloses a selenium-enriched ecological bacterial fertilizer and a preparation method thereof, and belongs to the technical field of preparation of fertilizers. The selenium-enriched ecological bacterial fertilizer comprises the following raw materials: urea, urea phosphate, diammonium phosphate, potassium nitrate, boric acid, selenium potassium phosphate, zinc sulfate, corn straws,a biogas slurry, an EM bacterial liquid, a straw fermentation inoculant, CM bacteria, soybean lecithin, lignin, sodium alginate, chitin, an EM bacterial liquid, mushroom residues, selenium humate, aselenite, brown sugar, selenohomocystine, beta-oligomeric acid, stearic acid, sodium hexametaphosphate, N,N-dimethylformamide, ammonium persulfate, selenium ore powder, itaconic acid, dibutylcarboxyltoluene, silane coupling agent KH-550, diethylenetriamine, attapulgite, o-phenyl benzoic acid and polyvinyl alcohol. The selenium-enriched ecological bacterial fertilizer provided by the invention isprepared by the steps of preparation of compound fertilizer particles, preparation of a film coating material liquid, coating of the fertilizer particles and drying; and the ecological bacterial fertilizer provided by the invention can improve the yield of crops and the content of a selenium element.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a selenium-enriched ecological bacterial fertilizer and a preparation method thereof. 【Background technique】 [0002] Selenium is an essential trace element for the human body, an antioxidant to maintain the balance of the body, and is known as the trace element that dominates life. Selenium can enhance the body's immunity, prevent diabetes, cataract and cardiovascular and cerebrovascular diseases, and also has the functions of detoxification, detoxification, prevention of liver disease and protection of the liver. When planting crops with high selenium content, it is necessary to invest in fertilizers with high selenium content to increase the enrichment of selenium in plants, so that selenium can be absorbed by the human body.
