Abstract
People use plastic film mulching to increase soil temperature, keep water and protect crops from insects and grass, therefore, which increased crop yield. However, with the film used years increasing, a lot of film residuals accumulated in the field. As a result, the increasing residuals destroyed soil structure, affected agricultural environment, harmed the crop growth, and furthermore, affected the food safety and human health. So, government should strengthen environmental publicity to improve the understanding of the film pollution, work out the residual film management laws and regulations, develop the recycling economy to reuse the residuals, and research biodegradable films and other ways to prevent agricultural environment from pollution.
