摘要

地膜覆盖技术大大提高了农业生产效率。然而,它也带来了土壤污染等环境问题。生物降解地膜作为环境友好型替代品,因地区差异和作物生长差异而呈现出不同的特性。本综述以文献和从科学网等数据库收集的数据为基础。本研究全面概述了可生物降解地膜的发展、类型和降解特性。得出以下结论:(1)使用可降解地膜可以保水、保持土壤温度、改善土壤营养、提高土壤呼吸速率、促进土壤微生物活动。(2)生物降解地膜可促进作物根系发育,抑制杂草,缩短作物生长周期,提高作物出苗率,扩大作物种植范围。(3) 目前,生物降解地膜的不完全降解性、相对较高的成本及其降解产物对土壤的潜在危害仍限制着其在农业生产中的广泛应用。本研究旨在为今后研究和应用生物降解地膜提供参考,希望能促进其在农业可持续发展中发挥作用。

Classification of Degradable Mulch Films and Their Promotional Effects and Limitations on Agricultural Production
Film mulching technology has greatly improved the efficiency of agricultural production. However, it also causes environmental problems such as soil contamination. Biodegradable mulch films, which represent environmentally friendly alternatives, present different characteristics depending on regional differences and crop growth differences. This review was based on the literature and data collected from databases such as the Web of Science. This study provides a comprehensive overview of the development, types and degradation characteristics of biodegradable mulch films. The following conclusions are presented: (1) Applying biodegradable mulch films can conserve water, maintain the soil temperature, improve soil nutrition, increase the soil respiration rate, and promote soil microbial activity. (2) Biodegradable mulch films promote crop root system development, suppress weeds, shorten the crop growth cycle, improve crop emergence rates, and expand the planting range of crops. (3) At present, the incomplete degradability of biodegradable mulch films, their relatively high cost and the potential harm to soil from their degradation products still limit their widespread use in agricultural production. The aim of this study is to provide a reference for future research and for the application of biodegradable mulch films in the hope of promoting their role in the sustainable development of agriculture.
