Abstract In order to promote the application of biodegradable mulching film in pepper fields production，and screen suitable biodegradable mulching film products，this study compared the application effects of 3 different components of full-biodegradable mulching film，including tarch-base，PBAT + PLA，PBAT + PLA + PHA in pepper fields production．The results showed that 2 black full-biodegradable mulch BM2 and BM3 with PBAT as their main ingredient could all have accelerating effects on pepper plant height，spread width，stem thickness，and root system dry weight．Moreover，all of them could significantly increase pepper yield．The increasing rates were 67.8% and 72.7%，respectively comparing with those of the CK．The degradation law of these 2 kinds mulch film were applicable to pepper fields production，and the residual film would not affect the plowing operation of farm machinery after closing the garden．During spring pepper fields production the black full-biodegradable mulch film with PBAT as its main component could be used at Wuhan area．
