[Degradation Characteristics of PBAT Fully Biodegradable Mulch Film].

Replacing traditional plastic mulch with fully biodegradable mulch is an important research direction to solve the problem of "white pollution," but whether it can truly realize biodegradation is still the focus of 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） fully biodegradable mulch film and ordinary polyethylene （PE） mulch film, with no mulch film （CK） as the control. Macroscopic characteristics such as the degree of apparent cracking of the mulch film, loss of the mulch film area, and the rate of weight loss were observed, and the results were combined with the results of scanning electron microscopy （SEM）, Fourier transform infrared spectroscopy （FTIR）, and thermogravimetry （TGR）.
