The invention relates to a synergist rich in intermediate elements and nutrients based on sulfur and zinc and its application. The synergistic effects of nutrients include 38% to 75% of intermediate and trace element components, 0.5% to 4% of dispersant, 0.5% to 6% of wetting agent, 0.5% to 5% of film forming agent, 0.5% to 5% of film forming agent adjuvant, 0.5% to 5% of film-forming agent, 0.5% to 5% of film-forming agent, 0.5% to 5% of filler, 19.5% to 5% of filler, and 19.0% to 5% of water. Pigment After the components are evenly mixed,The product is liquid emulsion. The adjuvant of film-forming agent is ethanol or dodecyl alcohol ester. The synergistic effect of nutrients enables the formation of nutrient layers based on intermediate elements and trace elements on the surface rapidly and effectively.It is a kind of chemical fertilizer or not dried on the seed surface, and has good foliar spray performance and suspension fertilizer performance. The synergistic effect of nutrients is suitable for coating granular fertilizer with large elements and powder fertilizer.It provides nutrients for fertilizers with intermediate and trace elements such as sulfur and zinc； seed coating, which improves the strength and speed of seed germination, and provides seed formation activity； leaf spraying, Provide nutrients based on intermediate and trace elements, such as sulfur and zinc, for growing crops； and fertilization and drip irrigation,In order to obtain plant roots planted with other large element fertilizers and allow plant roots to absorb.La présente invention concerne un synergiste de substance nutritive riche en éléments méso et en oligo-éléments à base de soufre et de zinc et une application de celui-ci. Le synergiste de substance nutritive est constitué de 38 % à 75 % d'un composant à base d'éléments méso et d'oligo-éléments, 0,5 % à 4 % d'un dispersant, 0,5 % à 6 % d'un agent mouillant, 0,5 % à 5 % d'un agent filmogène, 0,5 % à 5 % d'un adjuvant d'agent filmogène,
