摘要/Abstract

摘要： 将具有抗菌、促生长功效的中药活性成分与壳聚糖进行复合,并辅以聚乙烯醇（PVA）和甘油作为功能助剂,采用共混交联技术成功构建了高性能生物质种衣剂复合基材体系。通过水溶性、吸水率、拉伸强度、透水率4项指标的综合分析,ZG4J4样品综合表现最佳,ZG4J4样品的组成为中药-壳聚糖、甘油和聚乙烯醇(PVA),其体积比为25∶2∶100。ZG4J4样品具有结构稳定、水溶性好、热稳定性强等特点;ZG4J4包衣组的种子发芽率、发芽势、发芽指数分别为95%、90%、15.726,均高于戊唑醇包衣和未包衣对照组,证明ZG4J4样品能明显促进种子萌发,是一种性能优异的玉米种衣剂基材。

Abstract: Active ingredients of traditional Chinese medicine with antibacterial and growth-promoting effects were compounded with chitosan, supplemented with polyvinyl alcohol (PVA) and glycerol as functional additives, and a high-performance biomass seed coating agent composite substrate system was successfully constructed using the blending-crosslinking technique.Comprehensive analysis based on four indicators, namely water solubility, water absorption rate, tensile strength, and water permeability rate, indicated that the ZG4J4 sample exhibited the best overall performance; the composition of the ZG4J4 sample was traditional Chinese medicine-chitosan, glycerol, and polyvinyl alcohol (PVA) at a volume ratio of 25∶2∶100. The ZG4J4 sample possessed characteristics such as stable structure, good water solubility, and strong thermal stability. The seed germination rate, germination potential, and germination index of the ZG4J4 coating group were 95%, 90%, and 15.726, respectively, all higher than those of the tebuconazole coating group and the uncoated control group; this demonstrated that the ZG4J4 sample significantly promoted seed germination and was an excellent substrate material for corn seed coating agent.
