Replacing traditional plastic mulch with fully biodegradable is an important research direction to solve the problem of "white pollution," but whether it can truly realize biodegradation still focus many scholars. In this study, field and indoor experiments were carried out in Pingluo County, Ningxia Hui Autonomous Region, using poly（butyleneadipate-co-terephthalate） （PBAT） film ordinary polyethylene （PE） film, no （CK） as control. Macroscopic characteristics such degree apparent cracking loss area, rate weight observed, results combined scanning electron microscopy （SEM）, Fourier transform infrared spectroscopy （FTIR）, thermogravimetry （TGR）. Combined microscopic features SEM, FTIR, thermogravimetric analysis （TG）, CO
