Boron-molybdenum foliar fertilizer and preparation method thereof

The invention discloses boron-molybdenum foliar fertilizer. The raw material components of the boron-molybdenum foliar fertilizer comprises nano-silica sol, boron fertilizer, molybdenum fertilizer anda stabilizer. According to the boron-molybdenum foliar fertilizer, elements of boron and molybdenum are added on the basis of the nano-silica sol, so that absorption and accumulation of heavy metal cadmium, arsenic and lead in rice is reduced after spraying of the foliar fertilizer, the yield and quality of rice and other crops are improved, and trace elements required by the crops are supplemented; and since the stabilizer is added to the foliar fertilizer, the boron-molybdenum foliar fertilizer also has a stabilizing effect. 本公开提供了一种硼钼叶面肥，所述硼钼叶面肥的原料组分为：纳米二氧化硅溶胶、硼肥、钼肥和稳定剂。所述硼钼叶面肥是在纳米二氧化硅溶胶的基础上添加硼钼元素，这样在喷施后可降低水稻等作物重金属镉、砷、铅的吸收累积，还提升水稻等作物产量、品质以及补充作物所需的微量元素，且因为在叶面肥中添加了稳定剂，所以本公开所述的硼钼叶面肥还具有稳定的效果。
