【Abstract】 As an environmentally friendly material, fully biodegradable mulch films have broad application prospects in agricultural production. This paper introduces the research background and significance of fully biodegradable mulch films, presenting commonly used resin types including polylactic acid(PLA) and polyhydroxyalkanoates(PHA). It details the preparation technologies and their impacts on film properties, while evaluating regional application status across agricultural regions. Aiming at the aging problem of fully biodegradable mulch films, this paper outlines the commonly used aging research methods, such as indoor accelerated aging experiments, field experiments. Furthermore, it deeply discusses the main factors affecting the aging of fully biodegradable mulch films and proposes methods to enhance their anti-aging properties. Through this review, we aim to provide valuable references for the research and application of fully biodegradable mulch films.更多还原
