摘　　要：农田地膜覆盖已成为一项成熟的农业栽培技术,它能保水、保肥、保持湿度,有效延长作物生长期,提高农作物产量。农田地膜的应用在中国得到迅速推广,石家庄市近年来农田地膜用量处于持续上升趋势。由于传统农田地膜残膜回收率低,且不易降解,随着农田地膜覆盖使用年限的增加,土壤中残膜量逐步增加,造成地膜污染。通过分析农田地膜污染对农作物产生的危害,针对残膜存在的问题,提出防治地膜污染的对策与措施,使农业生产能够持续健康发展。The farmland mulching film covering has become a mature agricultural cultivation technique. It can preserve mois- ture and fertility nicely, maintain the humidity, and effectively extend the crop growing period and increase crop yield. Thus, it has been quickly spreading all over the country. The usage amount of farmland mulching film has been in an upward trend in Shijiazhuang City in recent years. But the recovery rate of the remaining traditional farmland mulching film is low, and it is dif- ficult to degrade, so with the increasing usage of the farmland mulching film after durable years, the remaining film in the soil is gradually increasing, and this causes pollution. This article has analyzed the harm of the farmland mulching film pollution to crops. Aiming at the existing problems concerning the remained film, it provides strategies and measures to control the film pollution, in order to enable the sustainable and healthy development of agriculture.
