摘要
地膜覆盖是广泛应用的农业技术,但目前使用的传统塑料地膜在带来巨大经济效益的同时,存在严重的生态环境污染问题,影响农业的可持续发展,发展可降解环保地膜是必然趋势。本研究系统阐述了国内外光降解地膜、生物降解地膜、光/生物双降解地膜、液态地膜和植物纤维地膜制备材料、制备技术和产品的研究进展与应用现状,以及五种可降解地膜的优势和不足,并对植物纤维地膜的研究方向和发展前景进行了展望。本研究结果为进一步发展绿色环保、可完全生物降解的农用地膜,促进农业的绿色可持续发展提供了理论依据。
Mulching technique is a widely used agricultural technology.The traditional plastic film currently in use brings huge economic benefits,but also induces serious ecological pollution problems and affects the sustainable development of agriculture,so the development of environmentally degradable mulching films is an inevitable trend.This study systematically describes the research progress and application status of the preparation materials,preparation technologies and products of photodegradable mulching film,biodegradable mulching film,photo/biodegradable mulching film,liquid mulching film and plant-fiber mulching film at home and abroad,as well as the advantages and shortcomings of the five types of degradable mulching films,and provides an outlook on the research direction and development prospects of plant-fiber mulching film.The results of this study provide a theoretical basis for further development of green,environmentally friendly and completely biodegradable agricultural mulching films to promote green and sustainable development of agriculture.
