Abstract：The restof the plantfiber are naturalldegraded，resulting in a huge waste of resources.Plant fiber film is a special celllose film prepared by plant fiber， which can be decomposed by microrganisms in nature，thus becoming a degradable environmental protection film.This celllose film can be used in the fieldof crop mulching，and can effctively developand use plant fiber resources，and thedegradation productsare notharmful to soil and crops. Through the modification of plantfiber，itcan further enhance thestrength，wear resistance，acidandalkali resistance，oxidationresistanceand service lifeof plant fiber，and significantlyimprove thethermal decomposition ability offiber，which can make it maintain stable performance in high temperatureenvironment.In this paper，three plant fiber modification methods（chemical modification，physical modification，biological modification）and theirresearch status are reviewed，the existing problems are analyzed，and their development prospects are prospected.
