农用地膜残留污染的现状与防治

农用地膜良好的增温保墒效果已对中国农业产生了重大的、积极的作用，但同时随着地膜覆盖技术的普及，残留农用地膜也已经带来了一系列的负面影响，大量的残留地膜破坏土壤结构、危害作物正常生长发育并造成农作物减产，进而影响到农业环境，通过对中国有关地膜残留研究文献的综述，对农用地膜的应用现状、残留地膜的分布特征及影响因素，以及残留地膜的危害特点进行了综合分析，并针对目前存在的实际情况，提出了农用地膜残留污染的防治技术措施。

Present situation of residue pollution of mulching plastic film and controlling measures

Increasing temperature and keeping soil moisture effect of mulching plastic film have brought a positive and important progress in agricultural productivity, and also the residue of mulching plastic film in the field has already become a negative factor that affected agricultural environment, which destroyed soil structure and harmed growth of crop. Based on results of domestic study on this issue, the authors comprehensively analyzed the application situation of mulching plastic film in agriculture, and the distribution characteristics as well as the influencing factors, the harm ways of the residue of mulching plastic film. According to the actual situation, the techniques of preventing and controlling measures for residue pollution of mulching plastic film were put forward.
