摘　　要：为探究全生物降解膜在烟草种植中的应用价值,评估其在作物生长中是否具有良好的保温、保湿效果,本文通过全生物降解膜田间服役老化观测以及采用红外光谱、扫描电子显微镜、拉伸力学性能测试、凝胶含量测试对全生物降解膜在降解过程中化学结构、表面微观形貌、抗拉强度等变化进行分析。结果表明,全生物降解地膜田间服役51天时,作物根系处膜面仍完整,能够满足作物覆膜周期要求。此外,在作物采摘翻地后,生物降解膜可在田间实际环境中降解,无残膜产生。To explore the application value of a fully biodegradable film in tobacco planting and evaluate its suitability in crop growth with good thermal insulation and moisturizing effects,this paper analyzed the changes in chemical structure,surface micromorphology,and tensile strength of the fully biodegradable film during the degradation process through field service aging observation and infrared spectroscopy,scanning electron microscopy,tensile mechanical property test,and gel content test.The results indicated that when the fully biodegradable mulch film was served in the field for 51 days,the film surface at the root system of the crop was still intact.This could meet the requirements of the crop mulching cy-cle.In addition,after the crops were picked and ploughed,the biodegradable film could be degraded in the field under ac-tual environments,and there was no residual film generated.
