Abstract：Activeingredientsof traditional Chinesemedicinewithantibacterialandgrowth-promoting efectswerecompounded withchitosan，supplementedwithpolyinylalcool（VA）andlycerolsfunctionaladitives，andahigh-performancebiose coatingagentcompositesubstratesystem assucefullyonstructedusingtheblendngcroslinking techique.Compreensiveanalysisbasedonfourindicators，namelywatersolubility，waterabsorptionrate，tensilestrength，andwaterpermeabilityrate，ndicated thattheZG4J4sampleexibitedthebestoverallperformance；thecompositionoftheZG4J4samplewas traditionalChinesemedicinechitosan，glycerol，and polyvinylalcohol（PVA）atavolume ratio of .The ZG4J4 sample possessed characteristics such as stablestructuregodwatersolubility，andstrong teralstability.Thsdgerinationrate，germinatiopotetial，andgatio index of the ZG4J4 coating group were 95% ， 90% ，and 15.726，respectively，all higher than those of the tebuconazole coating group andthencoatedcontrolgroup；thisdemonstratedthattheZG4J4samplesignificantlypromotedseedgerminationandwasanecellent substrate material for corn seed coating agent.
