Research Status and Prospects of Three Biodegradable Plastic Films
As an important agricultural technology,plastic film mulching can provide insulation and increase crop yield during the planting process of crops.However,traditional plastic mulching is difficult to degrade in natural en-vironments,and aged and broken plastic mulching can also cause soil pollution and other problems,which will in-crease the economic cost of mulching planting.Therefore,further research on biodegradable plastic film and increas-ing its promotion and application has become an important development direction for plastic film covered planting.This article reviews the degradation principles,membrane materials,and methods of three common biodegradable plastic films in China,as well as the research status of biodegradable plastic films,liquid plastic films,and photode-gradable plastic films in recent years.The development prospects of these films are also discussed.
