Embodiment 1
[0010] Embodiment 1: The raw material of seed coating agent comprises: sodium sulfite, fulvic acid, effective microorganism (Em bacteria) culture, film-forming agent, protective agent. It contains 10-15% of selenium-enriched production-increasing mother liquor, 1-3% of protective agent, 40-60% of film-forming agent, and the rest is water, which is uniformly mixed and ground at normal temperature. Wherein the protective agent adopts carbendazim or thiram, the film-forming agent adds water to absorb and grind 3-8% of methylcellulose by weight, and after crushing polyethylene glycol 2-5%, it is dissolved in water greater than 60°C, and then It is prepared by adding 15-20% ethanol and 1.5-2.5% coloring agent, mixing and grinding. The seed coating agent can be used for coating seeds of wheat, corn, cotton, etc., and the ratio of drug to species is 1:30-50.
