Abstract

Recently, the demands of biodegradable plastic for mulching application have vastly increased due to environmental concern, conservation of soil health and ease of residue management after growing season. The raise in demands also reflected by the increased number of studies related to biodegradable plastic mulch in the past 10 years. Biodegradable plastic mulch film has emerged as a promising alternative material for mulching due to ease of installation, offers benefits comparable to polyethylene (PE) mulch film, in situ biodegradation and able to improve soil fertility. This review sheds light on recent advances in different formulations of plastic mulch film. Formulations based on single polymer, polymer blends and polymer composites of biodegradable natural and synthetic polymeric materials particularly for mulching application were discussed. Comprehensive discussions on the performance of different formulations used for mulching material are reviewed in this review article.

摘要

最近，由于对环境的关注、土壤健康的保护和生长季节后残留物管理的便利性，用于覆盖应用的可生物降解塑料的需求已大大增加。在过去 10 年中，与可生物降解塑料覆盖物相关的研究数量增加也反映了需求的增加。由于易于安装，可生物降解的塑料地膜已成为一种有前途的地膜替代材料，其优点可与聚乙烯 (PE) 地膜相媲美、原位生物降解并能够提高土壤肥力。这篇综述揭示了塑料地膜不同配方的最新进展。讨论了基于可生物降解的天然和合成聚合物材料的单一聚合物、聚合物共混物和聚合物复合材料的配方，特别适用于覆盖应用。
