The invention relates to a medium and
trace element nutritional synergist with abundant
sulfur and
zinc and application of the medium and
trace element nutritional synergist. The medium and
trace element nutritional synergist comprises 38%-75% of medium and trace element components, 0.5%-4% of dispersing agents, 0.5%-6% of
wetting agents, 0.5%-5% of film-forming agents, 0.5%-5% of coalescing agent, 0.5%-5% of fillers, 19.5%-40% of water and 0.5%-2% of pigments. Various components are uniformly mixed with one another to obtain a product which is flow
emulsion, and the coalescing agent is ethylalcohol or texanol ester
alcohol. The application includes enveloping granular
macro-element fertilizers and powdery fertilizers with the medium and trace element nutritional synergist for providing medium and
trace element nutrition such as the
sulfur and the
zinc for the fertilizers;
coating seeds with the medium and trace element nutritional synergist for improving the
vitality of the seeds, increasing the
germination rate of the seeds and improving the activity of seedlings; spraying the medium and trace element nutritional synergist on leaf surfaces for quickly providing the medium and
trace element nutrition such as the
sulfur and the
zinc for crops; applying the medium and trace element nutritional synergist to
drip irrigation and fertilization, allowing the medium and trace elementnutritional synergist and other
macro-element fertilizers to be fed to positions near the root systems of the crops and further allowing the medium and trace element nutritional synergist to be absorbed by the root systems of the crops. The medium and trace element nutritional synergist and the application have the advantages that a medium and trace element nutritional layer can be quickly and efficiently formed on the surface of each
fertilizer or the surface of each seed without
drying, and the medium and trace element nutritional synergist is excellent in leaf surface spraying performanceand suspension
fertilizer performance.
