摘　　要：基于农田残膜回收作业以及资源化再利用,在农田残膜回收作业质量指标体系设计中提出田间碎屑滞留量、有效回收物清洁率的概念,结合残膜收净率,提出3个约束指标以促进残膜回收机具技术进步和作业质量的提高,探索残膜回收作业质量的考核方式。田间检测结果证明,地膜厚度是影响收净率和有效回收物清洁率的因子,膜厚对碎屑滞留量影响不大,碎屑滞留量与耐候期、回收时地膜的完整程度有关。Based on recovery of waste film and reuse of resources,concept of field debris retention and cleaning rate of effective recovery was put forward in the design of quality index system for farmland residual film recovery operation. Combined with recovery rate of residual film,three constraint indexes was put forward in order to promote technological progress and improve operation quality for residual film recycling machine,and explore assessment method of residual film recovery operation quality.Field test results showed that thickness of plastic film was the factor that influenced collection rate and cleaning rate of effective recovery. Film thickness had little effect on debris retention. Amount of debris retention was related to weather fastness and integrity of plastic film during recovery time.
