The invention relates to the field of
crop fertilizers, in particular to a stabilized
selenium-enriched
fertilizer and a preparation method thereof. The stabilized
selenium-enriched
fertilizer comprises the raw materials including a
selenium-containing substance, an
amino acid substance, a soil enhancement substance, a stabilized substance and a
coating substance, wherein the
mass proportion of pure selenium in the selenium-containing substance, the
amino acid substance, the soil enhancement substance and the stabilized substance is 1:(1-10):(20-50):(100-200), and the mixture obtained by pelleting 1 kg
coating substance is added with 3-5ml of 3-5 percent
coating solution. According to the stabilized selenium-enriched
fertilizer, provided by the invention, in the respects of slow release, fixation prevention, absorption promotion and the like, after the stabilized selenium-enriched fertilizer is applied, the selenium enhancing ability of the
crop is remarkably enhanced, and the output is remarkably improved. The invention further provides a preparation method of the stabilized selenium-enriched fertilizer, which is simple and easy to implement, and prepares the stabilized selenium-enriched fertilizer with good use effect.
