description The invention provides a zinc foliar fertilizer. The zinc foliar fertilizer comprises the following raw materials: nano silicon dioxide sol, a zinc fertilizer and a chelating agent. The nano silicon dioxide sol and the zinc fertilizer in the zinc foliar fertilizer are combined to form nano silicon-zinc sol with a particle size of 20-50 nanometers. The nano silicon-zinc sol can easily penetrate trough air holes of crops and enter crop bodies to be utilized by the crops, and a coating is formed after the zinc foliar fertilizer is sprayed to be in contact with the air for a certain time, so thatthe zinc foliar fertilizer cannot be lost due to rain, dew, collision and the like, and retention of the foliar fertilizer is greatly enhanced. 本公开提供了一种锌叶面肥,所述锌叶面肥的原料组分为:纳米二氧化硅溶胶、锌肥和螯合剂。所述锌叶面肥中的纳米二氧化硅溶胶和锌肥结合形成纳米级硅锌溶胶,粒径在20-50nm之间,能够轻易的通过农作物的气孔等进入农作物体内被农作物所利用,且在经过喷施接触到空气后会在一定的时间后形成包膜,不会因为雨水、露水、碰撞等原因流失,大大的加强了叶面肥的滞留性。
