Abstract:

Se-enriched effects of Se fertilizer on red peanut were evaluated by foliar spraying and drenching on the roots. The results showed that Se content of red peanut increased to the standard for Se-enriched agricultural products in Se-enriched soil without Se fertilizer, and red peanut had strong Se-enriched ability. Foliar spraying and drenching on the roots of Se fertilizer had extremely significant impact on Se content of red peanut, and the effect of foliar spraying was better than drenching on the roots.

Key words: Se-enriched soil, Se fertilizer, Red peanut, Effects of Se-enrichment
