This study selected three types of ecological plastic films with different degradation times to conduct application experiments on potatoes in Tengzhou. The experimental results showed that the degradable ecological plastic film has the same insulation and moisture retention performance as ordinary polyethylene plastic film during the early stage of potato growth and before degradation, and can meet the film covering requirements for potato growth.After the degradation phenomenon occurs, the degradation process was continuous and stable, and the tensile performance significantly decreases when the potatoes are harvested, resulting in local crushing. Potato covered with ecologically degradable plastic film have good growth throughout their entire growth period, and there is no significant difference in yield compared to the treatment covered with ordinary polyethylene film, indicating good prospects for promotion and application.
