摘　　要：采用不同用量的戊二醛(0%、1.5%、3.0%、6.0%、9.0%)作为交联剂,对不同质量浓度的壳聚糖溶液(1.0%、1.5%、2.0%、2.5%)进行不同程度交联,探索交联壳聚糖溶液的成膜性能和包衣性能及其对玉米种子发芽率的影响。结果表明,交联壳聚糖成膜性能和包衣性能得到明显改善,2.0wt.%-1.5%(即壳聚糖质量浓度2.0%,戊二醛交联剂用量1.5%)样品的成膜时间为9.6 min,包衣脱落率为8.4%,包衣均匀度为91.8%,发芽率为93%。Different amounts of glutaraldehyde(0%,1.5%,3.0%,6.0%,9.0%)were used as crosslinking agents to cross-link chitosan solutions(1.0%,1.5%,2.0%,2.5%)with different mass concentrations to explore the film forming and coating properties of cross-linked chitosan solutions and its effect on the germination rate of corn seeds.The results showed that the film forming and coating properties of crosslinked chitosan were greatly improved.The film formation time of 2.0wt.%-1.5%sample(i.e.,2.0%chitosan concentration,1.5%glutaraldehyde crosslinking agent)was 9.6 min,the coating shedding rate was 8.4%,the coating uniformity was 91.8%,and the germination rate was 93%.
