摘　　要：[Objectives]This study was conducted to investigate the effects of lignin-based fully biodegradable plastic film on the growth and quality of lettuce under open-field cultivation conditions.[Methods]In this experiment,compared with bare soil,a polyethylene plastic film(PE)treatment and two lignin-based fully biodegradable plastic film treatments(LBF-0.01 and LBF-0.008)with different thicknesses were set to study the effects on the growth and quality of lettuce.[Results]During autumn cultivation in Shanghai,the thermal insulation performance and yield-increasing effect of the two degradable plastic films were consistent with those of PE film,and effectively met lettuce growth requirements,but treatment LBF-0.01was better than treatment LBF-0.008.Moreover,lignin-based fully biodegradable plastic film could significantly increase the contents of Vc,soluble sugar and carotenoids in lettuce,and treatment LBF-0.008 showed the best effect.It could be seen that under the experimental conditions,the two kinds of lignin-based biodegradable plastic films with different thicknesses could be applied to the cultivation of lettuce in the open field in Shanghai in autumn,and LBF-0.01 had the best effect of increasing temperature and increasing yield,while LBF-0.008 had the best effect of improving quality.[Conclusions]This study provides theoretical basis and technical support for the further application of lignin-based fully biodegradable plastic film.
