生物可降解地膜研究进展与应用效果

Research Progress and Application Effect of Biodegradable Mulch Film

生物可降解地膜已成为可持续发展农业中聚乙烯不可降解地膜的替代品。相对于传统聚乙烯地膜,生物可降解地膜普遍存在水汽阻隔性较差、力学强度较低、降解周期较难控制等缺陷。对生物可降解地膜在力学性能和阻隔性能提高等方面的研究进展进行综述,介绍了生物可降解地膜在中短生长周期农作物铺设应用的效果。结合当前生物可降解地膜的研究与应用情况,对生物可降解地膜的研发应用提出相关的建议并对未来发展趋势进行展望。

Biodegradable mulch has become a substitute for polyethylene non-degradable mulch in sustainable agriculture.Compared with the traditional polyethylene film,the biodegradable film has the defects of poor water vapor barrier property,low mechanical strength and difficult control of degradation cycle.The research progress of biodegradable mulch film in improving mechanical properties and barrier properties is reviewed.The application effect of biodegradable mulch film in laying crops in short and medium growth cycle is introduced.Combined with the current research and application of biodegradable mulch,some suggestions on the research and application of biodegradable mulch were put forward and the future development trend is prospected.
