[Objective]To reduce the pollution of common plastic film on cultivated land and achieve the goal of sustainable agricultural development,stable food production and environment-friendly.[Method]The degradation rate of PBAT biodegradable film in cultivated soil and its effect on the growth and yield of fresh corn were investigated through the comparative test of biodegradable film and ordinary film.[Result]The biodegradable plastic film had good degradation performance,and had obvious inhibition effect on weeds in the early stage,which accelerated the growth process of maize.The degradation film began to break after the temperature increased,and the effect of heat preservation and moisture conservation was slightly worse than that of ordinary film,but the yield increase effect was significantly better than that of ordinary film.[Conclusion]Biodegradable mulching film could replace ordinary mulching film for corn crops,reduce pollution,improve yield and increase economic benefits.
