摘　　要：为解决太仓市农膜残留及回收问题,明确造成当前农膜残留的成因并提出相应的对策,本研究通过实地调研与定位点采样、问卷调查、关键信息人访谈等手段,对太仓市15个典型覆膜蔬菜区监测点进行采样分析。结果表明:2021年作物种植前地膜在土壤中的残留总量平均值为9.81 kg/hm^(2),种植后为9.55 kg/hm^(2),总体上属于低污染区,太仓市年均地膜残留量整体上呈下降趋势;通过调研与综合分析发现,地膜在土壤中的残留总量主要受地膜覆盖年限、蔬菜品种、农膜回收方式、作物种植方式以及地膜质量等众多因素的综合影响;种植方式和回收方式对农膜残留量的影响大于种植作物类型,是影响农膜残留量最为主要的因素。加强农膜回收可促进绿色可持续农业的健康发展,研究结果可为相关主体部门提供理论参考。To solve the problem of mulch film residual and recovery,and find out the causes and put forward the corresponding countermeasures in Taicang Town of Suzhou City,this study investigated and sampled field samples in 15 monitoring points of typical film mulching vegetable areas through field investigation,positioning point sampling,questionnaire survey and interviewed with key informant,and other means.The results showed that the average residual amount of mulch film in soil was 9.81 kg/hm^(2)before crop planting in 2021,and 9.55 kg/hm^(2)after planting.Overall,Taicang City belonged to a low pollution area,and the average amount of annual plastic film residue showed a downward trend.Through investigation and comprehensive analysis,it was found that the total amount of mulch film residual in soil was mainly affected by many factors such as plastic film mulching years,vegetable varieties,mulch film recycling methods,crop planting methods and much film quality,etc.The influences of planting method and recycling mode were greater than planting crop type on the residual amount of mulch film,which were considered to be the most important factors affecting the residual amount of mulch film.Recycling and reuse of mulch film can promote the healthy development of green sustainable agriculture,and the results of this study could provide a theoretical reference for the relevant departments.
