Summary:The invention discloses an efficient anti-dissipation selenium-rich fertilizer preparation method, which comprises: 1, mixing 30-80% by mass of sodium alginate, 1-5% by mass of one or a mixture of sodium selenate and sodium selenite, 10-60% by mass of humic acid, 1-10% by mass of one or a mixture of fish protein peptide powder and compound amino acid powder according to a certain ratio; step 2, spraying the material obtained in the step 1 with a chitosan oligosaccharide solution with a concentration of 0.1-1%, supplementing the water content to 10-35%, requiring convenient granulation, and using a roller or a turntable for granulation while spraying to form a high-activity selenium-rich inner core with a particle size of 2-5mm; 3, a chitosan oligosaccharide solution with the concentration of 5%-35% is used for spraying the selenium-rich inner core obtained in the step 2, it is appropriate that a liquid film is evenly attached to the surface of the selenium-rich inner core and does not run off, the ratio of th
